I got on the phone with Charter Tech Support and did the ipconfig/release and ipconfig/renew. This did not work. We then unhooked the cable from the modem and repeated the process. It picked up the cable modem ip of 192.168.100.1 at that time. We then reconnected the cable to the modem and repeated the process. The system lost the ip and 169.254.xx.xx was assigned. Charter sent a tech to the house and he worked on the system, changed the modem, etc. Still no luck with accessing the internet. He convinenced me (correctly) that the problem was not theirs. He said it could be spyware or a virus capturing the internet connection. I completely unhooked teh computer and brought it to my house to pull files off of it and re-format everything.
When I hooked the computer into my router and network it works fine. I thought maybe my router was blocking what ever was causing the problem so I hooked the computer directly into my DSL modem with Centurytel. Still the system worked fine. I returned the computer to the friends house and took my laptop along with me to verify that it was not a Charter problem. When I again plugged the problem computer into the Charter system, same problem, limited or no connectivity. Assuming it was Charter's problem, I double checked by un hooking the problem computer, powering down the cable modem and plugged in my lap top. The lap top is able to hook to the modem and works fine no problems what so ever. At this time, I reconnected the problem desktop and ran winsockfix. This did not solve the problem.
Thus I brought the problem Desktop back to my house and proceeded to remove files and complete restored the computer to factory defaults with a destructive restore reformating the hard drive etc. Again before and after the restore the computer hooks to my DSL modem and gains connectivity with no problem, both throught the router and direct to the modem.
I take the computer back and hook it up anticipating it will now be fixed. I connect it to the Charter Cable modem and same problem even after the restore. The laptop continues to run fine on the Charter Cable modem, however when it is disconnected and this desktop is then connected the desktop gets a limited or no connectivity.
I am stumped. I don't know what else to try or what could be causing this problem. I have changed the cables hooking the computer to the modem. The only difference I can think of right now is the laptop is running XP Pro and the desktop is running XP Home. Any suggestions would be greatly appreciated. Thanks Kevin
