Huh. : I suspect forcing 54Mbit will either not work at all (because the signal isn't : strong enough or your hardware doesn't support it), or it will negotiate a : speed up to 54Mbit (which would result in no functional change). Okay, this has me a bit curious, so I dug into it a bit more: SSID BSSID CHAN RATE S:N INT CAPS linksys 00:06:25:7b:25:3d 6 11M 35:0 100 E MYSSID 00:12:17:85:9a:3b 11 54M 39:0 100 E wahoo62 00:13:46:47:0f:0e 11 54M 4:0 100 EPS I'd have thought that a S:N of 39:0 wouldn't be all that weak, no? Looking at a post by Sam this past August, he calls 30:0 "very strong", though that was for an 802.11b link. I'd think that the higher the number, the stronger the signal. Is the above too weak to handle a full 54Mbps link?
