  • Sharing Windows Folders on a Network... other PCs see but can't access

    - by John
    I'm soooo tired of network setup issues. All I want to do is share a folder and all it's sub-folders so other PCs on my network can view and change this remote location. Why is it that setting a dir to "shared" doesn't actually make it usable in any way? The other PC can see the fodler but is unable to actually open it and look inside. It seems every time I want to do this I go through some semi-random process of right clicking the folder and enabling sharing, then looking in the folder properties to add permissions and other sharing... and then I end up with some folders working but others will randomly block permission on certain files or sub-dirs. I have 5 PCs in my local testing network and I cannot believe it should be this complicated... where is the simple "make this folder work on the network" option?! I have a mixture of XP, Vista & W7 machines, but this seems common to all of them.

  • Using a second wifi router as a wireless bridge

    - by Greg-J
    I purchased a D-Link DGL-4500 to replace my aging WRT54G around a year ago, only to find it nowhere near as reliable. It's been collecting dust since. I'm wondering if there is a way to use it as a wireless bridge so I can connect it to my home network and then use it's ethernet ports to provide network access to several devices. Is this something that can be done? If not, are there devices meant for this? Any help would be appreciated.

  • How to set up Asus RT-N66U in bridge mode with wired connection to main router?

    - by Milligan
    I have a wired router (TP-Link RT-860) in the basement where the cable service comes in. Eight wired ethernet connections span two buildings. I currently have a Linksys wireless router set up in bridge mode, but its signal doesn't span the whole area. I have purchased an Asus RT-N66U to replace it, but I can't figure out how to set it up in bridge mode. Does anyone know if this is possible? Second question: Would there be any advantage in installing DD-WRT on the Asus?

  • How to prevent eMule from jamming up the router?

    - by the searcher
    Usually, when eMule is started, after some time, I find that the router is jammed, so the internet connection on that computer stopped working, or it seemed to be waiting for some port to be freed up before it can connect to a website. This sometimes affect even other PCs or Macs using the same router. Is there a way to prevent eMule from hogging too much resource or ports? I see that there is under Options -> Connection "Max Sources/File" and a "Connection Limits - Maximum Connections". Right now I set them to really low numbers: the first to 120 and the second to 200, but what are good numbers to fill in there so that it can work well without jamming up the router or use up the network resource of the PC or Mac? Or could it be that the number of files that are "Waiting" is too high, and used up too much resource? (If so, can emule automatically limit the number to 10 or 20 to prevent using too much resource?) (This happened before on Linksys router, Netgear router, and the AT&T U-verse router.)

  • How to troubleshoot latency between 2 linux hosts

    - by Jimm
    The latency between 2 linux hosts is about .23ms. They are connected by one switch. Ping & Wireshark confirm the latency number. But, i dont have any visibility into what is causing this latency. How can i know if the latency is due to NIC on host A or B or the switch or the cables? UPDATE: The .23 ms latency is bad for my existing application, which sends messages at very high frequency and i am trying to see if it can be brought down to .1ms

  • client subscribed to a multicast group not receiving data

    - by Abruzzo Forte e Gentile
    I have a network that was setup for multicast traffic IN Machine A there is a server application generating multi-cast traffic. I have also different clients subscribing to that mulicast traffic -some client are in the same machine A -other clients are in machine B,C,D # Address I am using IP : 239.193.0.21 PORT: 20401 I don't know why but the client in machine A , even if they join the group, don't receive any data while (and this is the funny part) machine B,C and D receive everything. Checking with Wirshark I can see that the UDP traffic flow is there in Machine A. I am using LInux/Red-Hat Enterprise 6.2 What should I look at? Any setting in the os? Firewall or what?

  • Can I use the Airport Express as a an uplink between two networks?

    - by Ant Swift
    I have two separate networks using different IP ranges, 192.168.0.* for the wired only, isolated network and 192.160.1.* for the wireless only network which is connected to the internet. The wired network has a network printer setup and working and I want to be able to share it out to members of the wireless network (see diagram below). In short I need some kind of uplink between the two networks. Currently running a cable is out since there is no suitable route. I have a spare Airport Express and I am wondering if I could attach it to the wired network and have it join the wireless and act as the uplink between the two. Anyone know if the device is capable of this?

    - by Samuel Adam
    I want to ask why there is only me on Task Manager's Users tab. Originally I wanted to be able to chat with other clients on my local network using msg command, but I can't found any other user. How to see other users on the same network? I use Work Network, and all of the users is using wifi to connect. I googled about it, but no information is close enough. As much as a newbie question it sounded, I really appreciate any help. Thank you ! :)

  • How to restrict access to a specific wireless network to only 1 user profile in Windows 7.

    - by Mathlight
    Hi all, I'm using Win7 SP1. I've got multiple users on the laptop that can / must connect to a wireless network, lets call it Wireless1. I've got an second wireless network, (lets call it Wireless2), which I want to limit access to only the admin user of the laptop. Now I can remove Wireless2 in the network manager every time, but i want a more user friendly solution, so that only the admin can connect to Wireless2, and all the other users cannot ( they may see the network, but must enter the password, like all other networks ). Any ideas?

  • How to route broadcast packets from machine with two network interfaces on same subnet

    - by Syam
    I run RHEL 5 and have two NICs on one machine connected to the same subnet: eth0 192.168.100.10 eth1 192.168.100.11 My application needs to receive and transmit UDP packets (both unicast & broadcast) via these interfaces. I've found the way to handle the ARP problem and I've added routes to handle the routing problem: ip rule add from 192.168.100.10 lookup 10 ip route add table 10 default src 192.168.100.10 dev eth0 (and similarly, table 11 for eth1) The problem is that only unicast packets gets routed properly. Broadcast packets always go out through eth0. I tried removing the rule for 192.168.100.0 & 192.168.100.255 from table 255 and adding them to my tables. But then I see ARP requests being given out for packets to 192.168.100.255 (obviously, no nodes respond and nobody gets any data). Due to several techno-political issues, I'm stuck with this configuration and can't change subnets or try something different. I've tried SO_BINDTODEVICE and it works, but I'd prefer a solution that doesn't need my application to run as root. Is there a way to get this working? Any help is highly appreciated.

  • Can't find PC on network

    - by Simon Verbeke
    I just got myself a new laptop, and set it up. It is connected to the wireless internet in my home. I then wanted to create a homegroup between the laptop and my desktop, but they can't find each other. Probably because the desktop has a wired connection to the router and the laptop is connected to a wireless access point. The router and the AP are connected to a switch in the middle by cable. A sketch of the network: Laptop - - - Wireless Access Point ----- Switch ----- Router ----- Desktop ^ ^ ^ ^ Wireless Wired Wired Wired They both point to the same gateway and DHCP-server (on 192.168.0.1). And I can ping to that address from both PCs. When I try to ping either of the PCs the pings time out. The subnets are also the same (255.255.255.0) and the IPs are in the same range (192.168.0.114 laptop, 192.168.0.205 desktop). So I don't really understand what I need to do to be able to access either computer from the other. The weird thing is that Synergy (to use mouse and keyboard over the network) works, just by using the IPs assigned to both PCs. The acces point is a linksys WAP54g, but I'm unsure of the Router, it has a custom casing from our ISP and hides any clues for identifying the product. I'm going to google a bit so I can add that info later. Both PC's are Windows 7 64 bit. The desktop is Ultimate, the laptop Professional.

  • All internet requests in Windows time out

    - by Brandon
    So, I've run into a very strange problem with my home wireless network. Previously, at seemingly random times, the router seemed to disconnect all wireless hosts and cause all of the wired hosts to have a "limited connection" according to windows. In order to fix this, I had to unplug all of the wired hosts from the router, unplug the modem from the router, and power cycle the router. This seemed to solve the problem for a while until the exact same thing happened a day later and I had to go through the same process again. That's where I noticed something weird happening. There was one wireless host (a Windows Vista laptop) that seemed to be causing the router to disconnect the other hosts whenever it connected. When this happened, only that laptop was able to use the wireless from the router. When this happened, I disconnected it from the wireless (by disabling the wireless adapter) then reconnected it (by re-enabling it) and now it, like the other hosts, couldn't connect. I've never really seen anything this strange happen on our network before. So, I restored the router to factory settings and the problem seems to have vanished except one crucial problem. There's another host (a Windows 7 laptop) that was perfectly able to connect before all of the router issues and even in between the crashing and power-cycling events but now says its connected and says it's able to reach the Internet, but all requests time out. In any browser I've tried, the tab says connecting to [site]... for a solid minute and then tells me the request timed out. When I try to ping google.com in cmd it also says request timed out. In frustration, I booted into a dual-boot Ubuntu installation on the Windows 7 host and the connection works fine, to my surprise, as ubuntu is where I am now typing this rather long question. I haven't looked through the event log in windows but will post anything I find in an edit I haven't tried connecting (in Windows 7) to any other wireless network, since The fact that it works in Ubuntu suggests its Windows and not the router but I didn't change any wireless settings in windows before it being able to reach the Internet and not. Does anyone have any clue what could have happened. I opened to buying another router as this one is almost a year old :) but I would like to know whats going on here. Thanks in Advance! P.S. Sorry for how long my question is, I'm a little anxious (:

  • A proper way to create non-interactive accounts?

    - by AndreyT
    In order to use password-protected file sharing in a basic home network I want to create a number of non-interactive user accounts on a Windows 8 Pro machine in addition to the existing set of interactive accounts. The users that corresponds to those extra accounts will not use this machine interactively, so I don't want their accounts to be available for logon and I don't want their names to appear on welcome screen. In older versions of Windows Pro (up to Windows 7) I did this by first creating the accounts as members of "Users" group, and then including them into "Deny logon locally" list in Local Security Policy settings. This always had the desired effect. However, my question is whether this is the right/best way to do it. The reason I'm asking is that even though this method works in Windows 8 Pro as well, it has one little quirk: interactive users from "User" group are still able to see these extra user names when they go to the Metro screen and hit their own user name in the top-right corner (i.e. open "Sign out/Lock" menu). The command list that drops out contains "Sign out" and "Lock" commands as well as the names of other users (for "switch user" functionality). For some reason that list includes the extra users from "Deny logon locally" list. It is interesting to note that this happens when the current user belongs to "Users" group, but it does not happen when the current user is from "Administrators". For example, let's say I have three accounts on the machine: "Administrator" (from "Administrators", can logon locally), "A" (from "Users", can logon locally), "B" (from "Users", denied logon locally). When "Administrator" is logged in, he can only see user "A" listed in his Metro "Sign out/Lock" menu, i.e. all works as it should. But when user "A" is logged in, he can see both "Administrator" and user "B" in his "Sign out/Lock" menu. Expectedly, in the above example trying to switch from user "A" to user "B" by hitting "B" in the menu does not work: Windows jumps to welcome screen that lists only "Administrator" and "A". Anyway, on the surface this appears to be an interface-level bug in Windows 8. However, I'm wondering if going through "Deny logon locally" setting is the right way to do it in Windows 8. Is there any other way to create a hidden non-interactive user account?

  • Two routers on the same network

    - by qroberts
    My ISP has supplied me with a modem/router all in one and it isn't very good. It loses its settings and dies frequently. So I have another router in my apartment (Linksys wrt310n) that is connected to the modem via LAN-LAN port connections. I want to give my Linksys router the DHCP role and also have the ISP modem DMZ everything to the Linksys router. I want to be able to have all computers connected to both routers on the same network as well. I have been able to make it so that the Linksys has a DMZ to it from the ISP modem, but ISP modem LAN port - Linksys WAN port, so they were on different networks. Is there a way to have it so that both of them are on the same network but the Linksys router handles DHCP and port forwarding?

  • How do I connect to my home's primary wired network through an extra (wireless) router?

    - by Matthew Patrick Cashatt
    Thanks for looking! I have set up a desktop PC in my workshop. The Cat 5 cable connects from this PC to a wireless router which is connected to my home network. The Internet connection is working just fine. However, the "wired" network this is on shows up as a different wired network than the one that the PCs inside my house are connected to. This is a problem because I would like to connect this workshop PC to various shared resources like printers, HD Homerun (cable tv card), shared drives, etc. When I go to "Network and Sharing" and attempt to find the network that the PCs inside my home are connected to, I don't see it. Any help is appreciated. Thanks!

  • How to make Windows 7 use the internet connection that I specify

    - by user138957
    I have a LAN adapter and a USB wireless internet connection. When both connected windows 7 always uses the USB. I tried changing the metric values but no luck. Let me explains the steps I took. Currently automatic metric on all adapters. LAN connected. ipconfig shows that it is connected to the correct ip/dns/gateway etc. IPv4 Route table shows Metric 24 Then connected USB. ipconfig shows USB connectivity then LAN in that order. Internet is now through USB. IPv4 Route table shows Metric 4249 for LAN and USB is 41. Gateway for USB shows "on-link". netstat -rn shows USBDEVICE on top. Changed LAN metric to 5 and now the route table shows LAN as 9 (not sure why it added 4) and USB as 41. netstat shows LAN then USB. ipconfig shows LAN then USB. But still connection is through USB. How do I know? Task manager shows utilization only through USB as well as speed is showing around 1mbps rather than LANs 10mbps. How can I get win7 use LAN while USB is connected. I am just trying to use USB as a backup just in case I lose LAN connection. Please help!! I thought i will make USB metric manually to say 10. But it says I have to reconnect for it to be effective. Currently USB still shows below LAN and still has 9 and 41 in the table. Disconnected USB. Table shows LAN metric as 24 (Not sure why it got changed from 9 and setting got reverted by to automatic) Reconnected USB. Now in the setting still shows 10 and the route table shows 11 for USB and LAN shows 4249 (settings shows 4245, 4 less)) For some reason restarting USB is resetting LAN setting when reconnected. Thanks

  • Unable to share internet by using HOSTEDNETWORK after installing AVAST recently

    I was able to share my laptop's internet with my smartphone by using this command "netsh wlan start hostednetwork". But when I installed Avast in my Windows 8 OS, I am able to start the hostednetwork as before and my smartphone also finds the virtual AP but still I can't use internet on the smartphone. It's like the internet sharing has been disabled by the Antivirus. How do I tell Avast that its okay to use the hostednetwork?

  • How can I get the same SSID for multiple access points?

    - by krosenvold
    I need to upgrade my existing wireless infrastructure and this time I want 2 access points to cover my house, since I get blind spots no matter what with a single AP. I have physical cabling to my central network available for both access points. I would really like these two to interoperate seamlessly as a single SSID. How do I do this? What are the features that the new access points I'm buying would need to support?

  • Windows XP Pro 'Connect to' logon box greyed out with Guest

    Have a machine i've just nuked and paved to be used in a public enviroment, yet still connected to a Workgroup. Would like it to prompt for a logon when accessing any of the network shares as different departments will be using it. It does prompt for a login but the username field is greyed out. Have disabled simple file sharing, disabled guest account, changed Local Security Policies (Network access Sharing and Security model to 'classic') all to no avail. A google around has lots of other people with the same issues, lots of 'fixes' with very few feedback. Of course none of these work for me! :)

  • Connecting a Wifi router to receivers with a cable instead of antenna?

    - by 31eee384
    This is a very strange question--I'd go so far as to say it's a stupid question. I'm being told that it is possible to, to describe it briefly, use a cable to connect an access point and a receiver directly to one another. This means that I would unscrew the access point's antenna, and attach one end of a cable to the port. Then, on the wireless receiver, I would also unscrew the antenna and plug in the other side of the cable. I'm being told the connection would work after this, just as a normal Wifi connection would. Bonus mini-question: if this works, would it still work if a splitter were attached to the access point and multiple receivers plugged in to the network? What would happen if I do this? Based on my surprisingly deficient knowledge of radio transmission, I don't think it would work. I would like some help knowing why it won't (or will) though, if possible. This is a somewhat hypothetical question--I realize that Ethernet does this exact job very handily, and I could just throw in a switch instead of the splitter. I simply feel that I should understand this scenario. Thanks for any help you can offer.

  • Home Network Stopped Working

    - by James
    I have a home network where a machine running Windows 7 Ultimate N acts as a central hub for other devices to access media. This has been running for around 2 years now and there has been no recent configuration changes. The machine has a static IP address (192.168.0.3), which also has not been changed. A few laptops, Sonos music system and mobiles are using the machine for music/video mostly. Additionally, post 3389 was also open for RDP. I used a no-ip agent to map a hostname so I could RDP to the machine from the internet. As of yesterday when I try to ping the machine, I get PING:Transmit Failed, General Error I noticed however, the IP it is pinging is 0.0.2.233. All shares etc are no longer functioning including RDP. On the machine itself, an IP config shows like nothing has changed. It still shows the expected IP. If I ping itself from its hostname, I get the same error as above. machine has been rebooted, the router has been also. Any ideas where to even start on this?
