Strange WLAN issue with ral(4) in hostap mode

2009-01-01 Thread Damon McMahon
Greetings, Ever since I installed my MSI-PC54G2 ral(4) PCI card in my OpenBSD 4.3 i386 box running in HostAP mode I've had a weird connectivity issue. Put simply, connectivity with laptops is very iffy, but desktops are fine. Symptoms are that connectivity FROM the access point TO the node is very

Thanks, Todd, and my apologies go to Jussi for misunderstanding his point. I can replicate this behaviour. Windows allows me to change the "Power Save Mode" on the Atheros AR5008 card used by Apple in the MacBook Pro to "Off" which resolves the issue (when the MBP is booted into Windows, anyway).
