Hi Antiloop
Did some testing on wrt54g too, indeed most of the time connection drops to 2 or 1 mbit, although i had some stable connections at 11mbits, once connected at 11 mbits it stays connected at that speed, used channels 9 and 13.
I also did some testing on my Cisco AP342 and connection is always 11 mbit, with or without WEP, 64 and 128 bit, on all channels, both with long and short preamble, so it is possible
Could it have anything with the broadcomm chip, as far as i know, used in both the WL500G and the WRT54G ?
No comment from Asus yet ?
