Can't get computer to connect to Internet

post #1 of 17
Thread Starter 
Tuesday, I got a call for one of our clients that works from home. The computer (new), wouldn't connect to the Internet anymore and she wasn't able to work from home on the computer.

When I went out there, I noticed that it wouldn't even ping the router or other computer attached. Tried a few things, new NIC drivers, etc. Determined that the network card (onboard) went bad after a lightning storm.

For what its worth, she had a laptop that I was able to connect to the Internet through the SAME cable connected to the SAME port on the router/switch/cable modem.

Today, I get a call that it is doing it again. Except this time, I was able to ping the router.

What I CAN ping:
192.168.0.1 (router)
8.8.4.4

I can't , however, ping by hostname to google.com ... even if I'm using the ISP DNS or google DNS.

While on site, I got rid of AVG, Bonjour ... but was still unable to get anywhere with the network connection. I could ping out via IP but got nothing using multiple DNS servers.

===========================

After that, I brought it back to our office. As soon as I plugged it in the network it started working fine ...


Are there any suggesions?

I would try using a different router to determine whether the current DSL line/router is damaged or not.

I've connected my personal laptop to the router (all 4 ports) and their laptop to the router (all 4 ports) with no problems.

Unfortunately it's a cable modem / wireless ap / router / switch all in one so it can't be replaced one component at a time.

Was able to find out what the problem was. Apparently something happened to the all-in-one cable modem/router/wireless/switch device and it couldn't auto negotiate anymore with the network card in the desktop.

The network card in the desktop is an Intel gbit card and the other computers I was connecting to it with were only 10/100. What would happen is the computer would connect and work fine for a few minutes but then it would start trying to figure out what speed the network was at (10, 100, 1000), fail at discovereing that and then just drop completely.

First thing I do when troubleshooting is checking that I have a valid address.
