Belkin Wireless Card

Hey everyone, any help here would be much appreciated.

First, I'll start off by sucking up and saying that I've found this site immensely helpful over the past couple of weeks in which I've been setting up my Linux system!

I'm currently having problems with my wireless PCI card. It's taken about a week, but I have actually managed to get it working - temporarily. After about 15 minutes of working, I get an error regarding the IRQ of the card and it seems that the system shuts it off.

I'm running Debian Sarge with kernel 2.6.8-2-386 and using the NDISwrapper drivers for my card. The card is a Belkin F5D7000uk and I'm using the Windows 2000 rt2500.inf driver.

The outputs of lspci and dmesg (abridged!) are as follows:

Also, what has happened a couple of times is that the system won't start directly after this has happened. It hangs just after this point in the start up process:

ndiswrapper version 1.1 loaded (preempt=yes,smp=no)
ndiswrapper: driver rt2500 (Ralink Technology, Inc.,06/10/2004, loaded

Sorry for the huge post, but I hope somebody can shed some light on this!

From your description it looks like the card uses the Ralink rt2500 chip. If so you are in luck - there is a native linux driver for this. See:

With Debian you will need at least the kernel header files to compile this. I have used the rt2500 driver with a PCMCIA card and it works perfectly. I haven't checked out the new and more experimental rt2x00 driver.

I think some distros e.g. latest SuSE already include this driver. As one of the few wireless drivers with manufacturer support I would hope it would make it into the kernel sometime. Haven't checked for it in 2.6.13 tho'.

Thumbs up

Hey, thanks very much for your help. I wasn't aware that there was a Linux native driver for this card.

I've installed the latest beta version of the rt2500 driver and (fingers crossed) it seems to be working alright so far. Lets hope it carries on doing so...

Thanks again,
