Okay, it seems that a lot of people (not just Windows 8 users) are having the same problem with internet connection. I recently bought a computer off a friend that he had recently installed Windows 8. Despite already not being satisfied with the new OS, I've now begun to encounter this problem:
My internet connection worked fine at my house to begin with, but now I can't seem to make the internet connection last. Sometimes it lasts for up to around 20 minutes, but sometimes a matter of 5 seconds before dropping out again. Each time it drops, I troubleshoot and without fail it says "Default gateway is not available", but says it's fixed, and the internet works fine until it proceeds to drop out again. Sometimes it has ALSO come up with "DNS server is not responding", but that never says it's been fixed, only detected, and also "Problem with wireless adapter or access point", which does say is fixed.
My laptop is Dell l502x, the wireless adapter is Intel(R) Centrino(R) Advanced-N 6230 and I
m running Windows 8. I've tried un-checking the box to save power or whatever, and manually changing the IP addresses in the Internet Protocol Version 4 (TCP/IPv4) properties. I have spent about 7 hours of my day reading other forum posts like this but have still had no success. Please try to help me!
