Turning them off didn't fix it.

I have switched to 802.11b:

        inet netmask 0xffffff00 broadcast
        inet6 fe80::20f:b5ff:fefa:9196%ath0 prefixlen 64 scopeid 0x1
        ether 00:0f:b5:fa:91:96
        media: IEEE 802.11 Wireless Ethernet autoselect (DS/5.5Mbps)
        status: associated
        ssid homenetwork channel 11 bssid 00:19:db:0a:39:e6
        authmode OPEN privacy OFF txpowmax 37 bmiss 7 protmode CTS burst
        bintval 100

Sometimes it goes to 11Mbps, but usually stays at 5.5. Guess what,

That's for TX, and is for packets whose size <= 250bytes.

browsing has been much better now. Even though slowness occured a couple
of times in the last 16 hours on 802.11b, it hasnt actually halted
completly once.

One thing that's is very strange is the NIC did recv mac frames sent by 11g mode AP. I would suspect they were discarded by upper layer because of csum error.
