• Wireless Disconnects Randomly, then won't reconnect

  - by Nironan12

  Okay, so I have a Gateway laptop, with Windows Vista SP2, and a Linksys-Cisco WRT54GL Wireless-G Broadband Router. When I boot up my laptop, it automatically connects itself to my home network. Then at random times, it disconnects itself from said network. I go to reconnect it, but I get an unknown error and none of Vista's suggestions are working. Sometimes, after 5-10 minutes, it will reconnect itself. I've already tried updating the firmware. I can't install any other firmware, or make a factory reset. My dad owns the router and buys the internet and he won't let me TOUCH it. I can't do ANYTHING to it.

• Dell Vostro 1510 can't connect to wireless--how can I fix this?

  - by Miss Spider

  I'm having some trouble with my Dell Vostro 1510. I installed wubi on it two days ago and I've only been able to use the Internet with an ethernet cable. The network seems to definitely recognize that the wireless--even other peoples' wireless--is there, but it can't manage to get on. I'll post the lpsci here, so that you can see the Broadcom card I'm working with. I have downloaded the kernel 2.6.39-0-generic, which doesn't appear to have done a lick of work. 06:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

• trying to set up wireless router, failing

  - by j j

  Hi, I am trying to set up Netgear's wireless-n WNR2000 router, following their oversimplified 5- step process for plugging in wires, and I'm not having any success. It comes down to: once everything is wired and turned on in the correct order, all of the LEDs match the image they give of 'what should be lit up', but their setup disk still doesn't find the router. They have a site to set up the router manually, www.routerlogin.net, which I cannot navigate to, even while wired directly to the router. http://192.168.1.1 doesn't connect to anything, either. The interesting part: i get ping replies from Google's DNS server at 8.8.8.8 while this is set up. but cannot connect to any web site by name, since the router's DNS isn't set up. One thought is that the router and modem both have the same IP address, so it's conflicting, but I'm not sure how I'd resolve that. Any ideas?

• Computer freezes, wireless network icon disappears

  - by Heidi

  As you can see I have two problems. I have a Toshiba Tecra A3 computer. It is 5-6 years old and it is connected to a D-link router. For a period now it has not been working correctly. The computer freezes either when i try turning it on or when I have been using the computer for a short period of time. The times the computer works normally I have a problem with a disappearing wireless network icon, and so I have no internet. Can this be fixed or do I have to buy a new computer? I only use the computer for internet surfing and easy tasks like word etc, so I would like to keep it as long as possible.

• Wireless Bridge -DHCP

  - by Usta

  I was thinking of picking up a couple of TP-Link wireless routers, and setting them to bridge. I have a sep. LAN network that would have one of them, and I'd put one on my internet connection. Would I be able to keep my current IP subnets? (255.255.255.0 and 255.0.0.0) or would I have to pull my IPs from the same IP range. (I want to keep my current DHCP servers in place) The reason I want a bridge is so that I can VPN into the internal network.

• Connect a Sitecom WL-174 to another wireless router

  - by Thijs Wouters

  I used to connect via a Sitecom WL-174 directly to ADSL internet. There were some pc's which connected wirelessly and some connected with a wire. Now we got another provider and we need to use the router which came with it. It is also a wireless router. It works perfectly. But I need to connect the other pc's which were connected with a wire previously. Is it possible to connect the Sitecom router wirelessly to the other router? If so, how? Thanks.

• Blacklist a single access point of a wireless network

  - by Zr40

  At my university, one of the wireless access points is failing. When something tries to associate to the network using that access point, it deassociates the client, claiming 802.1X authentication failure. Other access points do work normally using the same credentials. The issue has been reported, but after a month it still has still not been fixed. Now, I'm looking for a way to blacklist the access point's BSSID, so the OS prefers other access points on the same SSID. How can I blacklist specific BSSIDs in either Mac OS X Snow Leopard or Windows 7?

• D-link Local wireless

  - by Filippo

  I created a wireless network inside a D-Link DIR-301 connected to a Mac, What I want is that every device to connect to this network if the browser automatically opens instead of the default homepage, it redirects to my website already set in the localhost of the machine which also has the router attached. I'd also like to see that instead of the IP to connect to the site, there will be a "fake" link. What do you advise me? how can I proceed? I state that I am a bit novice in this field, being more a web programmer.

• Wireless adapter won't enable

  - by user52141

  I bought a d-link dwa-125, plugged it in and windows recognized it right away and said everything was good to go. But there were no connection options. When I open up the network control panel and have it show me the adapters... the wireless adapter is greyed out and says it is disabled. So I tell it to enable. It says is it enabling, then says it is enabled... but the adapter stayed greyed out saying disabled. I am running 7 x64. I have reinstalled drivers, connected it via lan and had it update drivers.. same problem. It works just fine on any other computer in the house, just not this one.

• Ubuntu 12.04 wireless detected, but can't connect to 128-bit WEP enabled microsoft MS-700 base station

  - by ubuntufan

  I installed Ubuntu 12.04 on a Presario R 3000. The Wireless card was not detected (firmware missing). Based on several related posts, I downloaded and installed the b43 driver and wireless was finally enabled. However, I am unable to connect to my base station successfully. The base station is configured for WEP 128-bit. I tried both infrastructure mode and ad-hoc mode (with the channel, band, etc. configured). Appreciate any help in trying to get past this.

• Wired and Wireless Network Duplication

  - by Dave

  Howdy! Running into an issue when some of our client's have their laptop's connected via the wired ethernet network aswell as on the WLAN of the same network. There is know issues caused to the end clients.. BUT! Being a Managed Services Engineer i get pretty over the alerts that come through on our reports for machine's with the same hostname on the same network! We are not going to remove this monitoring because it does help a lot with detecting and stopping inferior users and things like that. So basically.. Question is, is there a way in Windows (third party programs welcome) to disable the wireless network when a wired network is connected and operational.. I know that Windows automticaly 'prefers' the wired network, however they are still both connected and therfore there is duplicate hostnames on the same network. Could also have stupid issues with DNS and things like that! Thanks!

• My wireless network slows down every 7.5 minutes when my desktop is switched on

  - by Dog Ears

  My network has lag spikes lasting for a few seconds every 7.5 mins. The spikes also effect any other computer connected connected to my wirless router at the time. My wife has to connect her laptop via a cable to prevent the lag causing problems when she's VPNing into her work. If I switch my PC off the problem goes away! I've got an Edimax 7728ln 802.11n wireless card and Speedtouch 585v7 (I'm with Be) I've Tried... Updated the drivers from Edimax website: 2.0.3.0 (it does say 3.0.2.0 in devices properties though) WLAN Optimizer doesn't seem to be helping What can I do?

• com0com silent install (test signed com0com.sys shows up as signed in explorer but not in Device Manager)

  - by Andrew

  My goal is to have the com0com serial driver install without popping up the install wizard on both WinXP and Win2000. I am working on WinXP x86. I have followed the test signing instructions for the com0com driver, replacing amd64 with i386 at line 60. I have added my test certificate as both a root and trustedprovider using the following commands: certmgr /add com0com.cer /r localMachine root certmgr /add com0com.cer /r localMachine trustedprovider And verified that it is listed under both locations. I then run the newly built setup.exe. This installs the signed com0com.sys file into C:\WINDOWS\system32\DRIVERS and sets up a pair of virtual serial ports and a bus between them. Using explorer, I go to the DRIVERS directory, right click on the com0com.sys file and verify that it has the "test" digital signature. I then go into Device Manager, open the "com0com serial port emulators" entry, pick an entry and do Properties-Driver and see that it says "Not digitally signed". I click details for the driver and can see that it is referring to the com0com.sys driver file that I just confirmed is signed. I found what might be a related issue but I'm not sure. Does WinXP demand a WHQL signature? If so, does that explain why the com0com.sys file is signed but the device driver entries say they aren't signed?

• OpenSolaris / Nexenta problems with NetXen 4-port NIC card (ntxn driver)

  - by ewwhite

  Hello, I'm running NexentaStor Enterprise on an HP ProLiant DL180 G6 server. The onboard NIC interfaces surface as igb0 and igb1 and work well. However, I've added an HP NC375T 4-port network card using the NetXen 3031 chipset. This card should be handled by the ntxn driver in the SUNWntxn package, but that results in "ntxn0: failed to map doorbell" messages upon boot. The network interfaces don't show up. After some research, I found HP's driver package for the card. The release notes for the driver package state: This version of the Driver is supported only on Oracle Solaris 10 5/09 & 10/09. Oracle Solaris 10 5/09 & 10/09 contain an older version of NetXen P3 driver package called SUNWntxn. So, adding another version of NetXen P3 driver package using pkgadd command might result in conflicts with the NetXen driver binary & related files. Users are advised to uninstall native SUNWntxn driver package before installing the new package. The install completes, but I end up with a different set of errors in initializing the card. ifconfig ntxn0 plumb ifconfig: cannot open link "ntxn0": DLPI link does not exist dmesg output: Jan 29 07:20:17 ch-san2 ntxn: [ID 977263 kern.warning] WARNING: Memory not available Jan 29 07:20:17 ch-san2 ntxn: [ID 404858 kern.notice] NOTICE: ntxn0: Mac registration error Trying to manually create the device files: root@ch-san2:/volumes# add_drv -i "4040,100" ntxn ("ntxn") already in use as a driver or alias. Update the driver: root@ch-san2:/volumes# update_drv -f ntxn devfsadm: driver failed to attach: ntxn Warning: Driver (ntxn) successfully added to system but failed to attach Any ideas on how to get this driver working, or should I ditch the card and go with an Intel or something else?

• Disable or remove filter driver for single HID device

  - by snoopen

  Running Windows XP in a corporate setting here. I have an issue where a filter driver is interfering with the functionality of different USB HIDs. For example graphics tablets do not respond while the filter driver is in place. I've also had the issue with foot pedals used with transcription software. My question is really two fold: A) what makes Windows use a filter driver on one HID but not another? B) when a filter driver is causing conflicts how can I disable it on the affected devices? Background I've previously narrowed down the issue to the filter driver by uninstalling the software (Funk Proxy Host) responsible for the filter driver. The software is a type of RDP we use here at work. (I might have even booted into safe mode and renamed the file, I forget). I believe the filter driver is present to disable or modify the use of the local keyboard and mouse while admin staff are assisting users. Either way I don't have the authority to just go uninstalling this software. As far as I can tell the software versions are the same, however I'm not sure if the device driver definitions are all the same as I don't know where these things would be located. To check for the presence of the filter driver I locate the hardware device in Device Manager, click Properties Driver tab Driver Details.... It shows up as ph32ihid.sys. Even though all machines are meant to have the same SOE and do have Funk Proxy Host installed I don't always have issues with the same HIDs. A few machines here the foot pedals without any issues. I've not had any machines work with the graphics tablet without uninstalling Funk software. Driver details I've just read up a bit more about filter drivers and found the drivers description in the registry under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ProxyHostHIDFilter" There it's called "Kernel-mode HID filter driver for the Proxy Host". Presumably I could also disable it here but that would be system wide which is probably not desirable?

• WinUSB application or User-Mode Driver as a filter driver for USB Analysis/Sniffer/Trending

  - by Robert

  A question to maybe some who have worked extensively with WinUSB APIs or use mode USB drivers - Does anyone know if the WinUSB API or a user mode driver can be used as a passive observer of USB connections, capturing notification of interrupts, control requests, data transfers...etc without interfering with other applications (such as iTunes) which would obviously require concurrent access to the device at the same time my application is monitoring the connection and displaying data on it? Or do you pretty much have to write a kernel-mode filter driver and inject yourself in the USB stack in order to make that happen? In the past, there have been a few credible options (libusb-win32 and usbsnoop to be specific) though both are built around the old DDK, not the Windows Driver Foundation, and are not really supported on a regular basis any more. I'm hesitant to build something significant around them, as a result.

• How to completely remove a wireless network setup from vista?

  - by 3d1l

  To remove a wireless connection setup I basically go to (network and sharing center) then select (manage wireless network) and then from the list of wireless networks I right click on the one that I want to remove and select (remove network) from the drop down menu. Problem is that when I go to define the wireless network again the system said that the network connection already exist so it seems that even when the wireless network definition is not longer display in the connections list, Vista keeps the configuration somewhere. So How can I be sure that a particular wireless network has been completely removed?

• How should I troubleshoot a problematic wireless connection on Linux?

  - by Gearoid Murphy

  I recently purchased a netgear 150 usb wireless dongle for use with my 11.10 Xubuntu amd64 system. Using the network-manager interface, I can see local wireless networks and enter the authentication details for my local wireless lan. Unfortunately, the connection does not seem to work, I keep getting notifications that my wireless has disconnected (but none indicating that I've connected). When I examine syslog, it seems to indicate that I've successfully associated with the wireless switch and that dhcp has successfully acquired an ip address but the log shows that the dhcp process keeps sending requests, eventually dropping the connection. 'ifconfig wlan0' never shows the dhcp address logged in syslog. I suspect that the problem lies with the usb dongle, my configuration or the wireless switch but I am not certain how to isolate the problem, can anyone provide some insight on how I should go about homing in on the cause of this problem or verifying the functionality of the individual components, thanks.

• USB Wifi will not connect on Windows 7 (Even though the driver installs OK)

  - by Pete Roberts

  Windows 7 will not connect to a WiFi Netowrk using a USB Network Adapter. I have 3 adapters, A Senoa SUB 364 (EXT), a Repeatit SU2410 USB V2 and a ZYXEL G202. All of these devices install OK on Windows 7 Home Premium on my Destop PC (64 bit) and on my Asus Wii Netbook (32 bit). In each case the adapter can be enabled/disabled and the driver properties says it is working correctly. When I try and connect to a network Windows 7 behaves as though the adapter does not exist and reports no networks. The Wii has an integrated adapter which works perfectly under Windows and connects to either of the 3 networks available to me. I have done all the checks I can on the configuration. What seems odd to me is that it happens to all 3 devices on 2 different windows 7 PCs both of which are working perfectly in any other respect. This suggests the common denominator is me and I must be doing something wrong.. what's also strange is that I cannot find any similar problems being reported on any of the forums. From what reading I've been able to do it seems like the new wifi virtualisation thingy in W7 is not recognising the adapters which suggests I', missing a configuration option somewhere. Looking forward to finding out if I'm not alone or just being stupid. Pete

• Networking problems in VMWare with wireless bridge

  - by Robert Koritnik

  Barebone data: virtualization: VMWare Workstation 6.5 (latest) Host: Windows Server 2008 x64 Guest: Windows Server 2008 x86 Host network adapter: wireless Guest network adapter 1: over Bridge VMNet (automatic) Guest network adapter 2: over Host only VMNet Problem When I surf the net within VM my internet connection just gets stalled (not dropped). It doesn't experience any timeout whatsoever, it just stops downloading/communicating. For instance: I start downloading a file with a browser (IE/FF/CR doesn't matter) and I have to pause/restart download when speed drops to 0. I could wait indefinitelly but connection won't pickup automatically. What did I miss in my network configuration? Update 1 I've tested this in various combinations. This works fine when host is connected via Ethernet. But when connected via Wifi, the connection on the guest works as previously described. It connects fine. It gets a valid IP from DHCP... Everything is cool as long as you don't start doing some intensive network traffic (ie. download a 2MB file) In this case it starts downloading and stops after a while. Speed just drops to 0B/s... Sometimes it picks up back, sometimes it doesn't. Connection still stays and works. I can ping around with no problem.

• Most transparent way to connect two LANS using a WET610N Wireless Bridge

  - by Spencer Ruport

  I have two wired systems hooked to a Linksys WRT54GL wired/wireless router which is also hooked to my internet. I'll refer to this as LAN1. I have two more systems in another room that are connected wirelessly. Recently I decided I would much rather have another wired LAN in the other room and use a bridge to connect them. This would be LAN2. Prior to hooking up the device I assumed that the ethernet side of the bridge would have a DHCP server so that I could simply hook it up to a switch and I'd be on my way. However that isn't the case which leads me to believe I'll have to add one to LAN2 correct? Or is there some way to have the DHCP from LAN1 also hand out IP addresses to LAN2? If I do need a DHCP device on LAN2 what would be best? Another hardware device or should I just install some DHCP software on one of the systems (since they're both on 24/7 anyway). Any recommendations would be appreciated. :)

• Handheld Linux device can't see one wireless network

  - by Nathan

  I'm using a Nokia N810 running OS 2008 (version 5.2008.43-7; should be the latest). It can see networks up and down the street in my neighborhood and can connect to mine using WEP. I can also connect to free networks at restaurants and the like. When I bring it into work, it can't see a wireless network ("No connections available"). When I use netstumbler on my laptop I can see a list of several essids showing green connectivity for the network. I know that the network has its essid broadcast, and I know that it's unsecured. When I run iwlist wlan0 scan, I see several APs with no essid, but I don't see anything with an essid set. I have verified using iwlist that my hardware supports the correct channels and speeds. I know this isn't a Nokia/mobile forum, but it's running what's basically a Debian kernel. Any suggestions on what to do in this case? I'm really frustrated by this. Thanks, Nathan

• Setting up 802.1X wireless connection on OSX

  - by hizki

  I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort (version 5.5.2). I am trying to connect to my university's wireless network, but it has a 802.1x security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my Mac? I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort (to version 5.5.2) it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password. Update: I have already tried to create a new "location", removed all the 802.1x user profiles and all the remembered networks, and made sure the in the TCP/IP tab 'Configure IPv4' is set to "Using DHCP". I also moved /Library/Preferences/SystemConfiguration/preferences.plist to my desktop in attempt to force the system to create a new set of settings. Still I can define the connection to work.
