I'm actually having some issues with the buffalo now, which isn't making sense to me hehe.
When my PC is wired to the router - the mobo's nic only shows 100 mb/s in the connection status, instead of gigabit, and I know the nic is gigabit. My laptop is wireless and shows 150-300mbps which is expected.
Using this arrangement, my laptop copies a large file from the PC at about 1.5mb/sec.
However, my PC also has a wireless N nic (it's pci, up to 150mbps). Using both the pc and laptop wirelessly, the laptop can copy a large file from the PC at about 9mb/sec.
I'm checking out the buffalo support forums, a lot of people have questions. The internet is perfect everywhere in my 2400sqft home though. I bought this based on a great review from maximumpc. They were getting over 30mb/sec at 65 feet away , or something like that.
I guess I have to keep messing with the NIC settings or something.
