tarnhelm Posted April 23, 2011 ID:419719 Share Posted April 23, 2011 I'm reasonably adept at solving computer problems, but this one has me stumped. I'm running windows XP/PRO SP3 on a homebuilt desktop computer. a little while ago it stopped connecting to our network unless I removed the adapter from the hardware list in device manager and re-scanned for hardware. i decided to replace the card with a new intel pro/1000 gt, but same problem. when I check the card out it tells me tcp/ip is not activated. I suspect there might be a conflict on the network. there are in fact two routers, but they do not share ip address ranges, so there is no possibility of getting the same address. I will probably disable dhcp on the lesser router, though I doubt this will have any effect whatsoever. so far I have been able reinstall the card in device manager every time. My luck could run out though. Any Ideas? I may ask Intel, though the problem is not different than what I had with my old USR adapter.thanks. Link to post Share on other sites More sharing options...
Firefox Posted April 23, 2011 ID:419760 Share Posted April 23, 2011 Hello, if you have two routers and they are both configured for DHCP, it is quite possible that two computers are getting the same IP. Especially if both routers are configured to give the same range of numbers in the DHCP scope.Disable one from giving IP numbers, or leave both on, just change the range that each one gives out numbers. For example one router can give out a range of say 192.168.1.50 - 100 and the next router could give out a range of 192.168.1.101 - 150. This way they will not give conflicting numbers.If you have two computers with the same IP, one will loose connection. Link to post Share on other sites More sharing options...
tarnhelm Posted April 23, 2011 Author ID:419872 Share Posted April 23, 2011 well I plan to do that, but the base ip addresses are different to begin with. I really do not think this is the problem though, otherwise deleting the card from device manager and reinstalling it would not work. I'll update later on.

tarnhelm Posted April 24, 2011 Author ID:420281 Share Posted April 24, 2011 that was pleasant. disabling dhcp on the router that is provided by verizon works until the IP address lease expires for the one I need to use for DHCP (a gigabit wireless N router). then all hell breaks loose and I have to do a cold reset of the verizon router. the two minutes it takes to rejig the Ethernet card on every reboot is a breeze by comparison. I'll get to the bottom of it. the router and modem are integrated, so I am stuck with this arrangement for now. Link to post Share on other sites More sharing options...
Firefox Posted April 24, 2011 ID:420309 Share Posted April 24, 2011 Another thing to try is check that you have the latest drivers on you network cards, and the latest firmware on the routers.... Link to post Share on other sites More sharing options...
tarnhelm Posted April 26, 2011 Author ID:421407 Share Posted April 26, 2011 thanks for the idea. the wireless N did in fact need updating, but had no effect. mind you this problem started out of the blue. when I fonally figure it out I'll post the solution.

tarnhelm Posted May 3, 2011 Author ID:424241 Share Posted May 3, 2011 fixed it. the driver for the defunct on-board ethernet adapter had magically revived itself. I found this thanks to another problem I was having with a memory leak, traceable to an nvidia service. Link to post Share on other sites More sharing options...
