• Macbook cannot see specific wireless network after being connected to it for a while

  - by donut

  Okay, so there's a single wireless network that my laptop has troubles with. My Macbook Pro used to be fine with it until it changed to using channel 13 (or 11?). Since then, after being connected to it for a while it disappears from my laptop's view. Other networks are showing up fine and other computers (including several Macs) have no troubles connecting to this network. If I clear my system cache using Onyx and then restart (sometimes a couple times) my laptop can see and connect to it again. But it seems that if I disconnect and try reconnecting I have to clear my cache again. One thing to note is that if I put my computer to sleep while connected to this network it has no problems reconnecting on wake up. I've got a 15" Macbook Pro 2,2 with Leopard 10.5.8.

• How can I view my IIS hosted sites on other machines on my network

  - by Truegilly

  Hello, at home i have a simple network setup conatining 2 machines and 1 belkin router. On one machine i have a site hosted with IIS7. Rather than the standard localhost/index.htm address i have added an entry in the HOSTS file pointing the local ip (127.0.0.1) to this domain - www.mysite.dev. i can access the site with www.mysite.dev with no problem. what i would like to do is be able to view this site from my other machine on the network. initially i assumed this could be done with a url like so MACHINE-NAME/www.mysite.dev, but the connection always times out. But I can ping MACHINE-NAME without problems. For testing purposes i have diabled the windows firewall on both machines but to no joy. Like a typical web developer, my techy/network skills are pretty poor. Can anyone see where im going wrong ?? thank you for your time Truegilly :)

• Mac claims to have connected to wireless network, but hasn't

  - by Mick

  I am attempting to connect a new mac OSX 10.6.5 laptop to a wireless network (I am a windows expert but a mac novice). It used to connect without problem to the network when I had the security set to "64 bit wep". Now I have changed the security on my belkin router to "WPA-PSK (no server)". I have two PC's and an old mac connecting via the new security setting without problem. Now I have the problem that on the new mac, the wireless icon is indicating a good connection (5 dark bars). Also the network name has a tick next to it on the wireless drop down menu. But I can not view any websites. I can not even connect to the router by typing 192.168.2.1 into a browser address bar. Any ideas where I went wrong?

• How to execute everything in the Local Area Network

  - by matnagel

  We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

• Mac Parallels - Bridged network

  - by Jack

  I am new to Apple and my task is to install VMs on a Mac server. I am trying to install 4 VMs and I want them to have separate IPs and be visible on the network as separate machines. What are my options? My research shows me that I can use a bridged network, but I have to select an adapter. I have only two network adapters, does that mean I can only have 2 VMs? And when I configure the 2 VMS, will my actual server have internet connection? Or does it use the Mac's address?

• Mixed network, Linux-to-Linux hostname resolution issues

  - by James

  At work we have an WinSBS domain at the heart of our network, which is all Windows PCs. The domain controller is acting as a DNS for these computers. I have recently added some personal use Linux machines to the network, without joining them to the domain. I have set up Samba with "wins server" pointing to the domain controller, which lets the Windows boxes resolve the Linux hostnames just fine. I also have resolvconf set up with the domain controller as a nameserver and the local domain as a searched domain, which lets the Linux boxes resolve the Windows hostnames just fine. However, the Linux boxes will not resolve other Linux hostnames at all. Given that I don't have control over the DNS server (I am not the network admin) and that at least one of the Linux boxes is not an always-on machine and is likely to change its LAN IP frequently (via DHCP), what service am I missing to make their hostnames visible to each other?

• OS X will not register newly installed network adapters

  - by Chris

  I have purchased an Edimax 7318USg and tested it on a Windows machine (works). The installation process for the software for this adapter runs smoothly. However, OS X simply does not recognize new network adapters. When you go to System Preferences/Network, a new network adapter should be present/there should be an alert. This is not the case. Why might this be? Is there a setting I may reset to force the operating system to recognize this? Thanks!

• My internet connection just got really slow - How can I troubleshoot it?

  - by Walden

  A few days ago my connection became really slow. I have DSL which should be 3mb down and 768k up. I'm lucky if I get 768k down and 200k up. It sucks. I called my ISP, Verizon and they did some sort of line test and told me the problem was on my end. I rebooted my modem several times, like they told me. I'm not really sure why I even bothered calling them, the guy on the other end was just reading stuff out of a notebook - pretty useless. So, I checked my network traffic in windows resource monitor, and there doesn't seem to be anything there hogging the bandwidth. What else could be slowing my connection down on my PC? on my router? Something else?

• Ubuntu Kernel Panic on Inserting Network Cable

  - by Skizz

  I've been having a recurring kernel panic with my Ubuntu 9.04 installation (see other posts by me). Today, I was fiddling around trying to get some cable attached when the system panicked. Looking at the layout, the only cable in the vicinity was the network cable. Upon further investigation, it seems that the system reliably panics whenever I insert a network cable. Removing the cable does not cause the panic. How do I stop the system panicking when I insert the network cable? If more information is needed, please add comments/answers and I'll post the required data.

• Planning home network

  - by gakhov

  I'm planning to setup my home network from scratch and want to ask professional opinions or tips. My home is connected to Internet with a cable connection (100 Mb/s). The devices I would like to connect are VoIP phone (RJ-45), TV (WiFi/LAN), 3 laptops (WiFi), 2 smartphones (WiFi), an iPad (WiFi), a Kindle (WiFi), a network printer and, probably, a home media storage (WiFi/LAN). As you can see, the most load will be on WiFi connections (probably, even if TV supports WiFi it's better to connect it by LAN?). So, I need help to choose the best router (or combination of routers) to support stable connections for all these devices and minimize the total number of routers/adapters. I like how Cisco/Linksys devices were working for me in the past, so preferably (but not obligatorily) I want to setup network with their solutions. Any thoughts?

• Problems connecting Centos to the network when running in VMWare

  - by Sakin

  Hi, I installed CentOs on VMware running on windows XP. When trying to configure it to connect to the internet, I get an error message when trying to bring up the network interface: [root@VMLinux ~]# /et/init.d/network start Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0... failed [FAILED] VM is running on a machine that has access to the network, I tried it on two different networks that have DHCP enabled. I tried to configure VMWare to use a bridged connection as well as NAT connection. An image of Ubuntu runs fine on the same VMware. What am I missing here? Thanks.

• gigabit network with adsl modem

  - by user51006

  Hi, i would like to build a gigabit network to connect the different computers at my home. I already have an 100Mb adsl router/modem but i have an hard time to find a 1000Mb one, so i came up with the idea of using a normal 1000Mb router or switch to put between the adsl modem and the computers. So i only use the adsl modem to connect to the internet and the gigabit router as dhcp to connect the different computers. But to get to the question. Will the 100Mb adsl router slow down my network? Will data travel like pc gigabit router computer or pc gigabit router adsl router gigabit router pc. My gut says it will go like in the first option but i have seen network hardware do some weird stuff. What do you think?

• Why does WebDAV fail from inside home network

  - by Claus

  On my OSX server there is a folder that is configured in the Server App to be accessible via WebDAV. This folder is used to sync OmniFocus. On my router, I have set up a dynamic dns. When I am outside my home network (physically away or when connected via a vpn), I can connect and sync fine via: https://<server name from dyndns>/<username>/<path to WebDAV folder> However, when I am in my home network, the connection to WebDAV does not work (other connections, AFP, f.ex, do work). What could be some reasons why I can't connect to WebDAV from within my home network? What log files could give hints and where are they stored? I am running OSX server 10.9.3. and server.app. Thanks for your help.

• Office 2007 network share access denied

  - by Rodent43

  Hope I have not duplicated an issue already posted but I could not find anything from the search... Right here is the problem, we have recently updated all our desktops to the MS Office 2007 suite and people have issues trying to open simple files like word documents... the systems are Windows XP (SP3) Novell Network with novell client Office 2007 when they try to open a word document from a usual network share word presents a message reporting Access Denied Contact Administrator So we assumed network permissions, none of which have changed...so try the same file with Wordpad and it opens fine, be it with formating issues of course... Now copy the file to your desktop, which is not redirected, and you can open the file in word as normal... so does anyone know if office 2007 uses some new permission when opening files? does it create temps or something... any pointers would be appreciated

• Hyper-V extensible virtual switch disables network

  - by Sebastian Krysmanski

  I just installed the Hyper-V role on my Windows Server 2012. It comes with something called a "Hyper-V extensible virtual switch". I assigned it to the only network card in my server. By doing so, the network card became useless/disabled/inactive/.. because the virtual switch disabled all features (IPv4, IPv6, Client for Microsoft Networks, ...) on the network adapter. Is this supposed to happen? I admit I've no idea what this "extensible virtual switch" actually does. A short explanation would be nice as well.

• In TCP/IP terms, how does a download speed limiter in an office work?

  - by TessellatingHeckler

  Assume an office of people, they want to limit HTTP downloads to a max of 40% bandwidth of their internet connection speed so that it doesn't block other traffic. We say "it's not supported in your firewall", and they say the inevitable line "we used to be able to do it with our Netgear/DLink/DrayTek". Thinking about it, a download is like this: HTTP GET request Server sends file data as TCP packets Client acknowledges receipt of TCP packets Repeat until download finished. The speed is determined by how fast the server sends data to you, and how fast you acknowledge it. So, to limit download speed, you have two choices: 1) Instruct the server to send data to you more slowly - and I don't think there's any protocol feature to request that in TCP or HTTP. 2) Acknowledge packets more slowly by limiting your upload speed, and also ruin your upload speed. How do devices do this limiting? Is there a standard way?

• 2nd/3rd version of wireless network appears

  - by neildeadman

  I replaced an old SpeedTouch ADSL router with a Netgear DG384 that I have and whilst doing so decided to change the wireless password. For this question assume my wireless network SSID is DeddersHome. On my netbook and macbook pro (running Win7) it won't connect to the Internet. When I hover over the tray icon for wireless it says "DeddersHome 2" and "DeddersHome 3" have no internet connection. What are these additional wireless networks? I can't see them in the wireless network list on any wireless device I have. Wired connections and wireless through my iPhone work fine. I saw this before with the SpeedTouch, but it just went away!! I also have one Apple AirPort Express connected to the wireless network which my Xbox is connected to (wired). This all worked before... I am going to remove AirPort to see if it is this causing the problem, but thought I'd ask the question to give it time for an answer whilst I continue to search. Cheers

• Can't connect to YouTube from specific network

  - by Tyilo

  Using my current network, I am unable to connect to http://www.youtube.com/. It doesn't matter what browser I use or if I use a cli-command (wget, curl). Error in Google Chrome: Oops! Google Chrome could not connect to www.youtube.com Error using curl: curl: (7) couldn't connect to host If I use nslookup to get the IP-address of YouTube, I get 173.194.32.32. If I go to http://173.194.32.32/ in my browser it can connect, but as Google is probably checking the Host HTTP-header, it shows Google's frontpage instead. There is no blocked websites on the router and other devices on the network seems to work. My computer only has this problem on this specific network. I am using Mac OS X 10.8.2 on a MacBook (mid 2009).

• Windows 7 Wireless Network Adapter Stopped Working

  - by Andrew B Schultz

  I have a Windows 7 Ultimate machine where the wireless adapter all of a sudden started having trouble connecting to wireless networks. Whenever I go to a new place and try to connect to a wireless network, it says that the DNS server is not responding, and tells me to go unplug the router and try again. After several locations in a row telling me this, I began to realize something was wrong with my adapter, not the routers. I am no longer asked to identify the security level for any new networks (Work, Home, or Public) like I used to be (it defaults to Public now - with the park bench icon). Often, resetting the router doesn't even work. Running the Windows 7 troubleshooter doesn't give me anything better than the advice to reset the router. However, the adapter will still connect to the wireless network at my main office without any problems. Does anyone know why a wireless network adapter can get so finicky so suddenly? Thanks!

• routing traffic between two network cards through firewall

  - by RubyFreak

  I'm trying to test a network device (firewall) using a Linux box, with two network cards, one interface connected to the WAN zone and another interface to LAN zone. The configuration is similar with that |ETH0| <-> | FW | <-> ETH1 So from both interfaces I'm able to ping the respective firewall interface. But i'm not able to fire something like: ping -I eth0 ip.from.eth1 and to get any answer. Is that possible or should the linux network namespace solution or user level tcp stacks (VMs are out of question)

• Can I increase the link speed of the RAS Server on our MS Win2k3 box?

  - by Ducain

  We are running a Win2K3 Server box, and I'm a remote employee that connects via VPN. I've been frustrated for some time by the connection speed over the VPN (the office HQ has a decent speed and I have a biz class connection here), and decided to do some checking today. This morning, I was dialed in and looked at the networking tab of the task manager, and I see that the adapter for the RAS Server (the box has 4 Gigabit adapters) has a speed that seems far too low. The speed for the RAS Server link hovers between 300 - 600 Kbps. The local connection (and others) all say 1 Gbps. Can I set this to a higher speed? Is this information accurate? Thanks for the input.

• Network adapters reliability

  - by casey_miller

  Can you help me with understanding of reliability of network adapters. Most of the time servers do have at least 2 NIC's bonded to provide sort of a HA for it. So in case of one NIC fails, the second would still do the job. I wonder which factors work when you use network adapters. I know that, the most important and weakest part of any computer system is: storage (i.e HDD). but how reliable actually network adapters are? There are more expensive ones, and cheaper adapters. In which cases do they actually fail? In what circumstances. May it be a intensive usage of them Time when it's on In your experience how often you found yourself changing NIC's due to their fail? Or just what's the typical lifetime of commodity NIC's? thanks.

• Mapping skydrive as network drive in macos

  - by vittore

  as you probably know, if you have windows live account you can use free skydrive 25 gb storage. Even more a lot of people know that if you go to your skydrive in browser and copy cid query parameter value (https://...live.com/...&cid=xxxxxxxx ) you will be able to map skydrive as network drive in windows using this network pass \[cid].docs.live.net[cid]\ I do now that if you have network share like \server\folder i can map it in macos too, as smb://server/folder. however it is doesn't seem to be a case with skydrive when i try to map it as smb://[cid].docs.live.net/[cid] finder tells it can't connect. Anyone know how to map it ?

• Dial-in VPN Routing issue when on 192.168.x.x network range

  - by Ian

  I'm not an expert on networks but have a small office on the 192.168.x.x. range which is managed by a vigor (2800) router. I have enabled the VPN dial-in option on the router so I can get to the server on 192.168.1.100 which works fine from my macbook when i'm NOT on a local network with that is on the 192.168.x.x range. e.g. works fine when I tether over my Android smartphone but when I try & connect when on my home network, it connects, I can access the router (192.168.1.1) but cannot access 192.168.1.100 - traceroute doesn't hop via 192.168.1.1 I have enabled "send all traffic over VPN connection but again, not joy... Feels like the osx platform isn't routing the traffic out to the vpn endpoint as the destination address is on the local subnet but expect it would be. This work fine on a windows PC on the same home network. Any thoughts on what the issue could be?
