My motherboard ( sig ) has build in LAN card. Every once in a while, the computer Windows XP will loose the internet connection, meaning; the net work status will be allright and connected, but, I will not be able to go online in any way. I have reset my modem, my router, and still nothing. I reinstalled Windows, and reset the modem, and ran Road Runner install software, it it seemed fine. Then it happened again. And once more, and now, once more. I used the above to fix it, but frankly I am sick of having to do that. I'm sure it's not my router, because I had the same problem with a DLink router, now I got a Linksys...so what do you think it is; my modem, or my LAN card. And if it's my lan, I really don't feel like sending my whole mobo back, I don't even know if I can do that in the first place. I just put in an old 3Com card, and it works fine for the time being, otherwise I would not be online. So any ideas anyone? Help would be very much appreciated, thanks bundles.
