Weird network issues, tech help omg

[Thor]

Ok so I suspect I might have a problematic motherboard, the onboard LAN refused to work for me so I bought a new NIC.

The new NIC is setup, I can ping to websites, do a tracert to a local newspaper webpage but when I go to firefox or IE it always hangs on waiting for the webpage to respond. In fact I even just now got calgarypuck to load maybe 1/10th of the data on its page, so a complete trickle of traffic.

Here's the pings/tracerts, maybe you guys can see something I don't, or at least help me come to the sad conclusion I need a new mobo.

how about ping -t www.yahoo.com

Let it run for a couple minutes, then hit control-c to get it to spit out the final stats on packet loss

Seems like a DNS or default gateway problem.

We can’t tell from the ping samples provided - he’s pinging himself, the wrong address for the router, etc.

You are totally right, we need way more information, I looked at the information and made too many assumptions. I never clued in that he was pinging himself, I just assumed it was another PC on his network. He couldn't ping what I assumed is his router, so thats what makes me think gateway. I didn't even consider the fact that it was the wrong address.

[Thor]

Ahh silly me lol, kk gonna boot up the big boy and do that test.

[Thor]

for ping -t yahoo I'm getting unable to resolve target system name.

Wouldn't this be likely a hardware issue if I've tried two NIC's and 1 wireless NIC with all the same weird problems of connectivity?

Are you connected directly to the modem or through a router? I know it's very basic (and you may have already tried) but rebooting the modem and/or router is usually required when adding a new device.

[Thor]

Yeah we drew cat5e from the modem upstairs directly to my room for the desktop, reset the router and switch as well, we get our TV from the same feed as the internet; silly Icelanders. Oh well 2 more years till we get our fiber optic line in.

Take the router out of the equation, I had something similar and it ended up being the router itself, it was very weird too because it was very intermittent.. like every few hours for only a few minutes.

What do you mean that your TV comes on the same line as your internet? What type of internet do you have? How is it all set up?

With certain cable modems if you have the TV signal and internet coming from the same source but split on a low quality unamplified splitter, this can cause the issues you are talking about.

The other thing is your hammer is probably causing electromagnetic interference. You should stop carrying it around with you all the time.

I would be more inclined to think it is a network issue, since 3 pieces of hardware that all essentially do the same thing don't work.

Try statically assigning an IP address, rather than use DHCP. Make sure you are using an IP address that isn't already taken. 255.255.255.0 for a netmask. Use your router's IP address for the gateway, and primary DNS server. Use 8.8.8.8 (or your ISP's DNS server if you know it) for the secondary DNS. Once the network adapter is configured, flush your dns (ipconfig /flushdns at command line).

If that works, then my guess is the DHCP server on your router is borked and sending out incorrect settings (or not sending out anything at all).

edit: This might be a stupid question, but is there a chance there is 2 DHCP servers running on your network? 2 routers maybe?

Ok so finally I did something I should have done last week, took my tower to my brothers and hooked it up to his internet, BAM both the expansion NIC and onboard NIC connected to the internet fine without any problems.

The internet companies here use the adsl for TV/Internet, so they have their own preconfigured routers that you have to use. On the back of mine upstairs it goes internet/TV/TV/internet for the router ethernet outs.

The interesting thing is that the ethernet line which goes right now to this laptop works perfectly, and when I plug it into the tower it doesn't work. Either by not even seeing the network to seeing it but not being able to load anything. Doing the usual cheap fixes like ipconfig /release renew did nothing and win 7's troubleshooting software always said to unplug and restart your router/nic.

All of those things I've done of course many times.

It could be that you have to register the MAC address of your devices with the ISP. You should call their tech support and run through their basic troubleshooting, that will help bring potential issues like this to light.

Well the tech is baffled too, I'd take the ethernet cable from my laptop, move it to the desktop and watch the router status show the laptop connected and then nothing shows up when the desktop is connected.

Tried all the troubleshooting steps we could, they have elevated it so we'll see what they figure out. Bizarre stuff anyhow, looking forward to find out what is the problem here.
