Router Connected To Dead Wired Computer - Network Still Works?
Jan 25, 2011
MY ISP is AT&T. I have their Westell DSL modem, with a bridged connection to a Linksys wireless router. The router is connected via ethernet to a dead computer: a 7 year-old Dell desktop that will boot up but shut down right away. I have been able to connect multiple laptops wirelessly to this network. I thought an ethernet connection was required in a home network such as mine? The cable has been plugged into a dead computer for several months and frankly I'd like to get rid of the desktop. What exactly is the ethernet requirement - just to be plugged into a port? Could I theoretically just yank the ethernet card out of the desktop and use it instead of the whole dead system?

I am running Ubuntu 10.04 on my Acer Aspire One netbook.The wireless connection works great, but the wired is totally dead.
When I plug the Ethernet wire, the little led next to the port doesn't blink.
If I do ifconfig, this is the output:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:1659 errors:0 dropped:0 overruns:0 frame:0
TX packets:1659 errors:0 dropped:0 overruns:0 carrier:0

[code]....
There is no eth0. Is that normal?
In the "Network Connections" GUI there is an entry "Wired connection 1", its "MAC address" field is blank.
How can I make the wired connection work?

Intalled a new router (Linksys Cloud 1200) yesterday. Immediately after that the 2 computers that were connected to the network could no longer access the internet. My laptop and my ipad can access the internet wirelessly. The laptop which was not connected to the network when I connected the router can access the network both wirelessly and wired. Printers attached to the network will print without a problem.Finally I took an old computer out of storage (running WinXP) and hooked it up to the wired network. It too has no problems accessing the network. So have to assume the issue is a software issue with the two computers that were hooked up to the network when I changed the router.I have read the posts here - I did a stack reset on one of the computers but no luck. I removed Norton 360 and Team Viewer which in other posts people said they had issues with...to no avail.
Since I dont have a wireless connection to the 2 computers that cannot access the internet - I cannot download TSG SysInfo. However here I did copy the ipconfig lines below from the desktop thats not responding. [code] Was working fine until I replaced the router. I tried going back to the oldrouter (Netgear) same issue - no wired internet connectivity.

I'm trying to set up a wireless network for my parents. I have a Belkin Play N600 router (model F7D8302) that I'm trying to hook up to an Acer desktop running Vista. The modem is a Siemens Speed stream 4100. I have a cable going from the ethernet port of the modem to the modem port on the router. The pc is connected to one of the other four ports in the router. The wireless works fine, but I can't get the wired connection on the desktop working. The Internet light on the modem is not on, but the modem works fine when connected directly to the pc. I've tried power cycling and resetting everything, but it's still not working.

I have a Cisco linksys router e1550. My wireless network is working fine, but my wired (PC) is not working?
Removing the router and having the modem connected to my PC works but when I put on my router my wired connection only works for a few seconds to none
So I think the router may be causing it, could it be the settings? Even though there at default.

About 6 months ago I bought a new router (Linksys E1000 v2.1) which worked great right out of the box. A couple months later I tried to setup a home network so that my two laptops could access a shared drive on my wired desktop, but for some reason they didn't show up as being on the same network. All computers involved are running Windows 7 if that matters.
Upon a recommendation from I friend I put DD-WRT on the router and it worked fine. Setup MAC filtering and WPA2 Personal security. This worked fine for about 4 months until today.
When I got home from work today I noticed my laptop wouldn't pull up any web pages, but it said it was connected. Then I noticed my iPhone wasn't connected either. I restarted my laptop and then it wouldn't connect to the wireless either (I could see the wireless, but I would get a Could not Connect error when I tried to connect to it).
I went to my desktop and it is working just fine, it is plugged into the back of the router. I also have an AT&T MicroCell (cell phone booster) that is plugged in to the back of the router and it works fine too.
I removed the encryption and MAC filtering. I then reset to factory (or "factory" DD-WRT) and now the wireless works, but it is MUCH slower than my desktop. I ran a speedtest on my desktop and got 12 Mbps down and 1 Mbps up. On my laptop, I get 0.03 Mbps down and 0.25 Mbps up.

I have two PCs hooked up to the same router, a BEFSR41. Both connect to the internet fine. One can access the router setup/admin page fine. On the other one, though, the router asks for a user name and p/w, but the setup screen never loads. I get the eternal "Loading" message but it never gets there.

Since the blackout beginning of this week from dlink I had to reset my camera totally to operate it again. works now again with iphone and with mydlink. But it only works as long it is connected via lan cable to my router. I accessed the set up (via ipaddress) and entered the router details to the setup but as soon I disconnect from lan it does not work anymore. What did I oversee.

So I have a Westell 7500 Modem/Router with Century Link DSL. I've been running a couple of laptops and my wifi enabled TV on the wireless. A few days ago I got a new desktop PC (Windows 7) and plugged the ethernet cable into it. Everything was great but the wireless was a bit slow for the TV so I plugged that in with an ethernet cable too. No problems for a few days. Today, we had a power blip and everything reset and I noticed that the internet light on the modem was solid red and I couldn't access the internet on any machine (ethernet or wifi). I called the ISP who said there was an outage in the area. A few hours later, solid green light on the modem BUT the TV (ethernet connected), my iphone, and my laptops could NOT connect, despite the network showing up with a full signal. Oddly, my new PC, connected via ethernet was fine so I played some Diablo (side note). Here's the deal: the new PC connects just fine but nothing else will. If I unplug the ethernet cable to the PC or disable the LAN connection, the red internet light appears on the modem. It seems as though the PC has hijacked the modem in some way. Even the TV won't connect with the ethernet cable. The only way the internet works now is if the modem is connected to the new PC. I've done all the resents - unplugged the modem and let it sit for 10-15 minutes, accessed the router settings, etc etc. Why would this start happening now after everything was working well for several days and how do I fix it? I need the wifi connection! Update: Plugged my Macbook Pro into the ethernet cable (took it out of new PC) and it works.

My computer is a 32 bit, Win7 SP1 with Pentium Dual Core 2.6 Ghz and 2Gb of Ram on a wired network. My wife has a similar system using a wireless network. She can ping my IP Address, but I cannot ping hers. We both have full access to the Internet. We are using the same workgroup, and both computers have file and printer sharing enabled and IPv6 addresses and DNS server addresses selected automatically.The problem appears to be with my computer?

My wired desktop cannot access the internet. Its still connected to my home network however. Every other computer on the network can connect to both the network and the internet just fine. the wired desktop is running windows xp. I have tried renewing the ip address, resetting IE settings, disabling the firewall, and I am currently running an anti-virus scan.

Is it possible to limit the bandwidth of one Mac on a wired network (only medium is the Netgear router WPN824v2)?
Both are Mac. Mine is newest iMac. Other one is a MDD PowerMac. Both are OS X. Mine is Lion.
I need to be able to throttle the bandwidth of the other computer.

Earlier today my modem died so I looked around and found an old modem (D-Link DSL-300T) lying around so I decided to use that one instead of purchasing a new one.It always worked great in the past, but when I tried it today I can only find a connection on this computer (garbage computer), the other 2 computers in my network can't connect to the internet, they can't even connect to the network at all.Oh and the router I'm using is a D-Link DIR-100. This computer is running windows XP, so is another one in the network and the one I want the connection to work on is running windows 7.

have a Cisco 5508 controller (version 6.0.199.4) that when I enable global multicast mode it will work for an hour or two and then it will kill the network. All internet both wired and wireless, access to server everything dead. I then have to directly connect to the service port and disable the global multicast mode. Then two reasons for enabling it are Docs2Go and LanSchool both require multicast to be enabled. I have it enabled on our wired network and it works OK there. ted.

I'm desperately trying to set up my old D-Link DI-524 on my parent's Toshiba laptop...I'm visiting and going thru withdrawals! I've installed it, run the wizard etc but it doesn't work...not even wired. I've tried various cable configurations and I get nothing. Both cables are good and work just fine connected to the modem. I've reset it a few times, upgraded the firmware and still nothing...I'd think I'd at least get it to work hard wired. My laptop can see the network I set up even...but no data transmission. I'm not a wireless expert, but I need to become one fast!

I am with Virgin media (UK) and have the 20mbps fiber optic connection. My area has recently been having problems with the broadband and Virgin has recently fixed these problems. However I used to get around 19mbps now that the problem is fixed my computer which is wired to the router gets about 0.4mbps downstream... However the 5 wireless computers all get 16mbps which is pretty good for them. Windows tells me that its a firewall issue and I currently can't use two programs, spotify and steam. They both have firewall issues, even if I turn off my firewall which is the windows one. I also have avast, and when I turn that off, still no good. I used OpenDNS, stopped using that flushed my DNS, that didnt work. I tried to optimize my computer settings, by changing various values in Regedit.All of this has done nothing. I should add that I have recently re-installed Windows 7 so on this fresh install it has never had decent internet speed. Which I thought was weird.. I have basically had these problems since the fresh install. All of my drivers are up to date.

Wired Internet works on laptop but not on desktop 1) Cable modem --> Switch --> Wireless Router --> ATA Adapter for the VOIP Phone --> Desktop Worked until i had a minor power outage. After which everything stopped ie No internet. So i tried scenario 2.
2) Cable modem --> Wireless Router --> Switch --> ATA Adapter for the VOIP Phone --> Desktop Got internet working (wired and wireless) for few days and then it stopped suddenly again. I tried both the above scenariosn again, but didnt work.
3) Now I connected my laptop (which i connected via wireless only before) with wire from cable modem straight to Laptop. Interent works
4) When I connect the same wire used successfully on laptop to my desktop, internet doesnt work. Both Laptop and desktop have windows 7?

I have a Netcomm NB9WMAXXn router and 3 laptops i want to connect to it wirelesslyThe problem is that the iwreless internet connection slows down and eventually drops out after about 30m unless one of the laptops remains connected via Ethernet to the router. The wireless laptops will remain connected to the router but the internet connection will fail. The laptop with Ethernet connection retains a very good connection so i'm thinking this is an issue with my router or it's configuration

Some time ago the mother-board ethernet card on my Dell Dimension 8400 failed, so I fitted a PCI card, and all was well: The failed card was Broadcom NetExtreme 57xx. The PCI one is Realtek RL8139. I got back onto the web, even though one of the (now two icons) in the system tray has a red cross, and all seemed well.
Recently I wanted to set up a home network with a wireless laptop, and though both machines seem to see each other I cannot connect the PC to the LAN to share files. The Ethernet icon in the tray has a red cross, and gives the pop-up "Not Connected - no connections are available". The Network and Sharing Centre will not let me connect, apparently because it thinks I am connected to a public network, which I cannot change to work or home. but it also has a red cross on the PC to Internet connection. If I run the troubleshooter, it cannot find and fix any problems. In the security settings app, I have set the radio buttons to be able to change the status of networks, and to rename them. If I try to connect from the laptop to the PC, I am asked for a network ID and password, but there is nowhere for me to set this up. I have a wireless dongle, but this gives the same symptoms. I am able to connect to a wireless printer (ethernet cable to router, then wireless to the printer).
I have tried many things, always making sure I have Administrator privileges. I don't know whether the problem is that the PC only sees the faulty modem, or is something to do with the public network status, which I have seen as a problem in many other posts, but none of the solutions have worked. I have uninstalled the faulty modem, but obviously cannot physically remove it, as it is part of the motherboard.

I've got an RV042 router at home and am connected from my office via the QuickVPN client ver 1.4.1.1.2. I can ping the RV042 and log into the administration page and make changes. However, I can not see other computers on the remote network. I can not ping them. When I open my Network page, I still see the computers on my local network.
All machines are running Windows 7 Ultimate. ISP is Comcast at both locations. WAN IP's are dynamic, but have not changed in over a year. Local IP's on the remote (home) network are static..[url]....

how to block a user from using the internet when they plug their computer into a router. My roommate has refused to pay her share of the internet and, being a college student, I don't have enough money where I feel generous enough to let her have free internet after stiffing me. Basically, I have 2 routers at the moment (hoping to fix this soon): my Qwest modem works as a router but I also have a Linksys router connected to it. The only phone jack is in her room so I have no way of stopping her from plugging her computer straight into the modem and/or router. I've configured the wireless so that she would be unable to access the, wirelessly but I'd like to know how to prevent her accessing the internet when she plugs her computer directly into either component.
