so i have a laptop sharing a wireless connection using ICS. it's connected via a crossover cable to a desktop and it works.... but only for a short while. About 10 minutes at the most. At first I had used this to get my xbox 360 to connect to xbox live, and that worked until i started pinging out of games after about 10 minutes or so. So i just ended up using the ethernet for that and stopped worrying about it. However i just recently got a used computer that i've just wiped clean and since i don't have an extra wireless card, i decided to bust out that crossover cable again. And the same problem is happening again. After 10 or so minutes, the internet cuts out and doesn't work on either computer until i physically remove the cable. The internet starts working again on the ICS enabled laptop, and it'll only work when i wait a second and plug it back in for the desktop. Confused yet? Sorry if this is so long to read, i've tried to be as descriptive as possible.
