How to make RT2500 connect at 54 Mbit/s

[mbar]

No matter what I do, e.g. "iwconfig ra0 rate 54M" my card always shows Bit Rate=11 Mb/s. Is there any magic I should use to make this work as G card? Apart from that, everything seems fine, I have active network connection.

My WLAN consists of two RT2500 cards, one PCMCIA in my notebook, one PCI in my desktop (which works as a router). Both of them won't work in 54M mode

Does your access point support 54M ?
If it does, have tried changing some settings on you AP rather than just trying on your computer?


For wireless to be running at 54G both AP & wifi card have to support 802.11G I think.

i don't know the card and don't own one so i can't try it out, but http://gentoo-wiki.com/HARDWARE_rt2500#Setting_up_Network edits the RT2500STA.dat file and sets WirelessMode=0 for mixed 802.11b/g. i don't know how up to date that information is, mind you. could well be that your drivers require a special method to set the mode.

I use two RT2500 cards in ad-hoc mode (link between two computers) I don't have and don't need AP. I know that RT2500 cannot work in master mode tough.

When your AP support 54M the card will go in 54M rate after a few seconds, mine also starts in 11M, then goes to 22M and eventually to 54M, it just takes a while. Setting it manually "stops" my card for going to 54M, so then it stays 11M...

Good luck,

OK, I solved it. I had to insert this:

AdhocOfdm=value
0: Adhere WIFI spec, the Tx MAX rate will be 11Mbps in Adhoc mode
1: Violate WIFI spec, the Tx MAX rate will be 54Mbps in Adhoc mode

into /etc/Wireless/RT2500STA/RT2500STA.dat
Wiki page http://gentoo-wiki.com/HARDWARE_rt2500 is outdated, as it specifies said option as:
AdhocModeRate=value
value
0: Adhere WIFI spec
1: Violate WIFI spec

AdhocModeRate does NOT work with drivers in portage.
