Q. Windows XP. Linksys WRT54G.
When my internet cable is plugged directly into my computer from the wall, my computer obtains an IP address and connects to my browser no problem.
When I plug the cable from the wall into my router and then from the router into the computer, it also obtains a IP address, says I'm connected but my browser will not work. This also happens when I connect to it wirelessly.
So basically, when I go directly from the modem to my computer my internet works fine, but when I go through to router, it says it's connected (Internet and WLAN light are both on as well on the router) and has IP address but the browser will not work.
I've tried so many things, PLEASE HELP!!!

Answer
make sure it gets IP Address, Gateway, & DNS. go to Start > Run > type CMD to open command prompt, then type IPCONFIG /ALL, make sure the adapter has tcp info.
Also don't use wireless and ethernet at the same time, 1 or the other, if you plug your ethernet in, disable the wireless, if you use wireless don't plug in the ethernet.
Make note of those IP Addresses, then from the copmmand line ping the default gateway ip (ie.. ping 192.168.1.1) or whatever your gateway IP is. if that works you can communicate with the router. Next ping an external host such as ping yahoo.com, if it fails ping the IP...ping 66.94.234.13 if that works its a bad DNS Server

Answer
I've done security audits for companies for very similar issues.
While I don't have all the info to definitively say what the cause is, there's are a few possible explanations
1) radio interference. I had a case where speakers were getting intermittent reception of a talk radio station! This is a very rare event, but it does happen from time to time.
2) you did have a program running and just didn't know it. To see if you're running something that's connected to the net, run netstat from the command line like so: netstat -ab This will tell you what programs are generating the network traffic.
I hope this helps!
