Cheat Engine

[Xeleron]

Well , it doesnt detect my internet anymore after my pc stand on for more then 3-4 hours.
mostly its on to download , but its anoying when i come home and downloaded almost nothing because the internet fell away.
The only solution i have found is restarting the pc. In internet network i have 3 routers.
A linksys and a Belkin and a FON (wifi). i use the belkin downstairs to connect to my other pc, a FON wifi router and a link to my other router.
i use the linksys for connection to my other pc ofcourse and a link to my xbox.
i plugged the internet cable comming from the linksys router into the internet connection on the motheboard.
Also yes i updated both routers firmware.
Pc Type : HP Compaq d530 2.7Ghz
OS : Windows 7

Thanks in advance.
