I have two computers on a wireless network. One is a dell laptop that works great with the wireless. The other is a computer that I built myself (after getting some great advice here!), which does not work so well with the wireless. I have the standard router that comes with ATT U-verse service, a 2Wire i3812V and a supposed 12 Mbps connection. It is in the other room wired to the TV (only about 20 feet away, with one wall between).
Using the ATT speedtest (http://www.att.com/speedtest/) with both computers in the same area, the laptop clocks in at usually between 9 and 11 Mbps. The desktop connection is really variable, sometimes as low as 1.5 Mpbs but rarely over 6. The USB adapter I have for the desktop is a Realtek 11n RTL819.
I'm assuming that the problem with the desktop is that adapter since all the other hardware is so much better than the hardware of the laptop. Do you think that is the case? Would a PCI card work better? If so, can you recommend one?
It seems to me with the hardware I have and the connection I have, the internet on the desktop should be screaming fast, but it just isn't. Very frustrating.
Thanks for your help,
mc
