Wireless configuration on 11.1: Minor configuration issue.

English Network/Internet
1

Hey everyone.

Just a minor issue I have with my wireless; I’ve got everything working, except that when I reboot my wireless card ‘forgets’ that it should be running at 54mb/s, and reverts back to 1mb/s. I’ve had to run “iwconfig wlan0 rate 54M” each time I boot.

Any help on getting openSUSE to remember to run at 54mb/s?

Many thanks… :smiley:

There’s a startup script at /etc/init.d/boot.local. Put that line in there and try it out. Might fix it.

What wireless card are you using? In 2.6.27, the kernel used with openSUSE 11.1,
most systems automatically adjust the speed to the fastest supported by your
particular setup. Although the card will go at 54 Mb/s, you might get higher
throughput at 48 or 36 due to excessive retries at higher nominal rates.

Also, please post the output of ‘dmesg | grep algorithm’. That will specify
which rate control mechanism is being used.

Thanks for the replies, guys.

swerdna, that fixed it. Thanks :smiley:

lwfinger, I’m using a Ralink RT2500-based card, a Belkin F5D7000, with the rt2500pci drivers.

dmesg | grep algorithm
phy0: Selected rate control algorithm ‘pid’

Try the drivers from compat-wireless-kmp-Flavor matching your output from “uname -r”.

Webpin - compat-wireless-kmp

openSUSE-Kernel:


modinfo /lib/modules/2.6.27.21-0.1-default/kernel/drivers/net/wireless/rt2x00/rt2500pci.ko
version:        **2.1.8**

compat-wireless:

modinfo /lib/modules/2.6.27.21-0.1-default/updates/drivers/net/wireless/rt2x00/rt2500pci.ko
version:        **2.3.0**

Strange that it stays at 1 Mb/s The ‘pid’ algorithm is generally more aggressive
than ‘minstrel’, but the rt2500pci driver in 2.6.27 may have a bug that is
keeping it from adjusting the rate.

It’s very strange. I’d say you’re probably on to something; if you want me to give you any data readouts for analysis let me know, but I’m pretty useless in any other capacity.

Akoellh, as much as I’d love to try out those drivers, everything is now running perfectly and, well, I’d rather not jinx myself.

Thanks again.
