What kind of connection speed should I expect with this "b"-type wireless connection? Kinternet shows ~1Kb/s -- isn't that ridiculous? With an 11 Mbit/s data transfer rate I think I should get 800-1000 KB/s. Thanks.

That IS ridiculous. I'm on an 11Mbit/s router two rooms away and I can hit 500Kb/s no sweat. There is a way to set the data transfer rate of your card from the command line. You can see what rates are available with "iwlist rate" as root. As for how to change it if it's wrong....I know there is a command, but I don't know it off hand. This will as least tell you what rates you are supporting though.

You are right. I did an ADSL speed test and I am getting 2200Kbps in download and 530Kbps in upload. But how can I find the maximum bandwidth on my WLAN? Is there a utility for that under Linux? Thanks.

I'm sure you can find something. I did a search at Softpedia... here are the results. http://linux.softpedia.com/progSearch Hopefully something there will help you!

the bad news: with a static ip assigned to the WMP54G v4 (PCI) wireless card and the 1.4.6.2 ralinktech driver my SuSE 9.3+ Pro computer hangs a few seconds or minutes after reboot, particularly upon launching a web browser (doesn't happen when card is configured to use dhcp). i tracked this down to a network issue since all is fine if i bring the network service down right after i log in.

the good news: there is this open source rt2x00 project at rt2x00.serialmonkey.com with downloads hosted at sourceforge.net.

the very good news: i've updated the rt2500 driver again using release 1.1.0-b3 from above. it works perfectly!!! obviously, the ralinktech module rt2500 release 1.4.6.2 was somewhat unstable. below is an excerpt from the Changelog file in 1.1.0-b3.
Code:
Changelog for 802.11g rt2500 driver and RAConfig2500 Utility

 Version: 1.1.0-beta3 
        * PCI Management Cleanup
        * Fix for RaConfig crashing on statistics (ChrisH)
        * Big-Endian fix for RaConfig
        * Channel change fix for adhoc mode
        * Fix for association to non-broadcast AP's
        * Fix to allow this device to create Adhoc networks
	* 4kb stacks are now supported (1190152)
	* Rolling of changes in Ralink 1.4.6.1 + 1.4.6.2 release including:
		* Fix- Mlme queue tail pointer
		* Add- WPANONE
		* Add- AUTH AUTO method
		* Fix- racing condtion in mlme.c and rtmp_data.c
		* Fix iwconfig - Link Quality(means Channel Quality), Signal level and Noise level.
		* Fix iwlist ra0 channel - print out

    KNOWN ISSUES
        * Promisc/Monitor mode only see's packets leaving AP (1009565)
        * RaConfig has multiple issues in configuration
        * Some pre-up config may not take affect (1103395)
        * Extra Beacon packets need to be tamed (1089461)
	* Noise values in scanning results are invalid (1246025)

    CURRENTLY NOT SUPPORTED
        * SMP Processors and Kernels (1099089)
	* Power Saving Modes (1159331)
        * USB rt2500 devices - please see the rt2570 driver
        * Bridging with other interfaces
last but not least, with this updated driver it is no longer necessary for your router to broadcast the SSID.

rt2500pci, and AMD64 SuSE 10.0.42 (10.1)

1st and foremost, I'm a relative Linux NOOB!! So apologies in advance, when I type something dumb. That being said, I'm having a devil of a time getting this wireless card to work with the "subject" titled config.

The instructions I read in the README file that I d/l from Ralinks website, although I tried to follow them, stop @ process "c" in the section entitled "Setup Sequence", saying SuSE version not supported - ok no surprise, since I'm running 10.1 and right in the readme file it says suse supported 8.1 and 9.0.

However, after reading through this thread, and using some of the tools discussed, I DO have rt2500pci, and rt2x00core (for kernels 2.6 +) running in lsmod. Also contained w/in /lib/modules is rt2500pci.ko and rt2x00core.ko (ko for kernels 2.6 +).

On to the problem, and some anomolies I have stumbled on.

1st if I get to playing with YaST, or the KDE Control Module for Wireless Networks, or certain commands with ifconfig, I'll get a process lock, then I can't even reboot my machine normally, I have to logout --> restart --> ctrl-alt-bksp --> login as root --> init 6, then the system locks on shutting down network interfaces, and I have no choice but to hit the reset button.

On 1st reboot after that procedure, rt2500pci and rt2x00core are NOT in lsmod, nor are they listed in /lib/modules, now I do a "normal" restart, and we're back to square one.

2nd if I ask the YaST utility to list my system components it says network adapters ra2500, blah, blah, drivers assigned, etc, etc...

There is no "device" name however, i.e. wlan0 (would be logical, but what am I thinking?!), anyway, while still in the "normal" state iwconfig shows l0, eth2, and sit0, but anything I try to do with eth2 (which I'm assuming, probably incorrectly, is the wireless adapter seen by YaST), for example iwconfig eth2 essid mycompany, then iwconfig - there are no changes.

3rd - if I go into YaST Modules, network devices, network card, there is nothing there.

4th - I have eliminated hardware failure, as I triple boot this same box, SuSE 10.1, WinXP Pro, and Win2K Pro, XP and 2K both work, XP with the linksys driver, and 2K with the Ralink driver (2K linksys driver caused memory errors).

ok, so what am I missing?

I have the fortune of having a raggedy old HP netserver LC3 running the same card - Win2K Server (ONLY driver that would work at all is Ralink, and it still drops packets occasionally), so I have a KVM where I can monkey with SuSE, and still be on line here.

All help appreciated!!!

Well, it's early a.m. here, so if my answer is bogus, apologies up front. That being said...if YAST doesn't show your network device as having an interface (i.e. wlan0) then it would definitely need configured. This link http://www.angelfire.com/linux/hardw...eMandriva.html is to my webpage. It's a walkthrough for noobies setting up a wireless card with ndiswrapper. You can follow the instructions and screenshots for how to set up the wireless properly through YAST. However, where they write "ndiswrapper" under module, you won't do that as you're not using ndiswrapper. I don't know if you should leave it blank, or type the ralink module listed in lsmod as I've never done a wireless card without ndiswrapper. Also, I don't have Suse 10 anymore, but I think it says "select from List" so that's probably what you'll need...if your card is in the list, you should be in business. Just finish the setup, MAKE SURE you set up a dns, and see what you get...

Overall, with lsmod listing your module, this should mean it's loaded. Sounds like all you need is to configure the interface wlan0 to be your ralink wireless device and all should be well. If you set up the wlan0 through network devices, then simply try "ifup wlan0" from the command line as root and you should retrieve an ip via dhcp. Then "ifconfig" as root should now show wlan0 with an ip and "iwconfig" shows what router it's connected to. Hope this helps...if you hit a snag, let me know.

well, I can't set it up as wireless, choosing rt2500pci as the module, then try and enable it, or I get the lockup situation, so I set it up as ethernet, rt2500pci as the module, but it won't enable, and the ONLY change that will take effect when using iwconfig is mode, it's default is auto, I can do a iwconfig eth2 mode managed, then iwconfig eth2 and it is changed, EVERYTHING else I try and change with iwconfig, I get no errors, they act like they're working, but going back and checking, it stays as it was.

Hummm, well, it sounds to me like maybe a firmware problem. You might see if you can use rpm.pbone.net or another site to find an updated version of your firmware. If so, try to remove the one installed with Suse and try the newer version. Outside of that, I'm not sure what else to try. If it's showing "eth2" as an interface, then it should to be configured. You might try "tail | dmesg" or just "dmesg" to see if you can see anything wrong there or see what it lists for internet devices in there. For example, in mine, it shows "eth0: Broadcom 4400 10/100 ethernet device" etc. See what is listed for eth2 if you can find anything. Other than that, I'm not sure what else to try... I'm just not sure why it would be locking up...that's what makes me think it could be a firmware issue, but I'm just not sure. Maybe it has something to do with setting up two devices to run off the same module if indeed eth2 is running on the wireless card.

You might see if you have the wireless tools package installed also...should be I think, but here's a link to the 9.3 version (which is fine to install). It's worth a look I guess: http://rpmfind.net/linux/RPM/suse/9....16.2.i586.html It contains tons of fixes and support for your card.

Ok, maybe getting somewhere, I don't know, driving me INSANE! dmesg, any reference to rt2500pci, rt2x00.core, or ieee80211 says "module not supported by Novell setting U taint flag".

Now why in the world would Novell include those 2 modules as part of the distro if they don't support them?

And yes, just checked, wireless tools package is installed KDENetwork3-Wireless.

Well, maybe that in and of itself doesn't mean anything, google search showed someone else having a similar msg. and a response to them said, that it just means novell doesn't support it - so if I was to call them for support they would tell me to call Ralink.

getting somewhere, I've got wlan-eth2 setup in YaST, iwconfig has all the correct parameters for my network, iwlist scanning shows what winblows does when I scan from this PC, shows my network and another one, however I can't get connected and pull a dhcp ip address. But apparently the NIC is working otherwise it wouldn't scan the local networks.

arggggggghhhhhh
