One of my few complaints about HP’s TX1000 is the 802.11g performance with the embedded Broadcom radio. 802.11a on the same wireless radio is better, but the G side performance was not up to my expectations nor was it as good as other Vista Broadcom chipset/driver combinations.
So, I asked my friends at D-Link for one of their new ExpressCard/34 draft 802.11n cards.
It (DWA-643) arrived this morning. The difference was like night and day. I can copy files over the network at blazingly fast speeds and no dropped connections.
D-Link uses Atheros (as opposed to Broadcom) chips in their draft N gear.
