[Wireless] Ndiswrapper flaky, bcm43xx slow

Hi everyone.

Recently i bought an hp tx1020ea (tx1000) - a fine laptop, crucially with an integrated wireless card.

Code:

03:00.0 Network controller: Broadcom Corporation BCM4310 UART (rev 01)

The bcm43xx driver is fine, but limited to speeds approaching 20kBps. Ndiswrapper is speedy, reaching >100kBps (this is an 8Mb connection), but the ping reveals the connection to be sadly inconsistent.

Code:

So, gods of Frihost, any ideas?
