I just bought my wife an Asus K53E laptop with Windows 7 so she can have portable internet while I'm gone. The internet is intermittent at best, very slow when it actually works. I updated all drivers on the laptop and router, even tried changing the channel on the router but I havent found anything that worked. I dont think its the router since my other laptop and desktop are working fine. I tried the Intel diagnostics tool, all tests past but the ping test, said no response from the default gateway and the DHCP server. Can anyone help?
