I'm using WPA but using it without any encryption doesn't change anything. At the same time it is possible to use an Atheros device (FreeBSD 7 stable box too) without any drawbacks. I'm able to regain performance if I restart the network, but sometimes I have to shutdown the computer first. The card: cardbus0: Expecting link target, got 0x0 ral0: <Ralink Technology RT2661> mem 0x88000000-0x88007fff irq 16 at device 0.0 on cardbus0 ral0: MAC/BBP RT2661B, RF RT2529 (MIMO XR) ral0: Ethernet address: 00:0e:2e:94:cf:4c ral0: [ITHREAD] Vendor Edimax, IEEE 802.11g MIMO cardbus, model EW-7608PG >How-To-Repeat: Just surf 1-2h and the performance will drop until almost nothing. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
