I recently got an N capable router, and have had connectivity issues ever since. Never had problem with G. The new N network uses WPA2 security, but Windows 7 seems to recognize it as WEP. Entering the passkey results in an error, and I'm thinking this is because of the security type.
I downloaded the latest wifi card driver directly from ralinktech.com, but that doesn't seem to have helped. Curious if anybody has encountered this before.
