ubuntu and belkin f5D6020v3 card

This particular card seems to use to Realtek 8180 chipset - rtl8180). There isn't a driver for this one in the Linux kernel, but there a Souceforge project with a driver: »rtl8180-sa2400.sourceforge.net.

From what you've posted, it seems the card can't get an IP address via DHCP, the other warning messages are unrelated, although the "There is already a pid file /var/run/dhclient.wlan0.pid with pid 0" seems odd, since there is no PID 0, and suggest a stale lockfile, but it might be harmless.

As for the keyboard locking up, there are some tips at »ndiswrapper.sourceforge.net/medi···php/Tips ,also if you are using the Windows XP drivers, try the 2000 ones instead (or vice-versa).

Don't use ndiswrapper except as a last resort. See the above post for native Linux drivers.

Thanks to both for the advice - I've d/loaded the rtl drivers but I get loads of errors when I 'make' - I've installed kernel headers and source thinking I was missing that. Now the error says something about gcc-4 which is what ubuntu uses as default. I'm not on that machine right now so can't paste the exact error. I've tried 'make -i' which ignores errors but it won't make, so I can't install the drivers.
Any other ideas, please?
thanks again for the interest

Thanks again jdong - here's what happened:

I'm lost again, I don't know what CONFIG_CRYPTO_ARC4 is. Any more pointers, please?

reply to blound
Its an option in the kernel. Looks like you may need to recompile your kernel with that option enabled.

reply to blound
no, arc4 is compiled under Ubuntu as a module, and it indeed works....

Edit the source files, and any line that references slot_name (a few printfs it seems like), remove them. Sounds painful, but they're useless debug messages that use a super old kernel API. It seems like they're all in r8180_core.c.

Thanks guys, that was QUICK. I started looking through r8180_core.c with vi (I know just enough about that to do some damage) and when I got to line 1500 without seeing any slot_name references I scrolled down to the end - it has 4190 lines!! Is there a quick way to look for slot_name references, please? My eyes are smarting already.
thanks

/slot_name in vi command mode.

Ok, thanks again (this is FUN) Now I have the drivers and this is what I have:

I took eth0 down (with ifdown eth0) to see if I have network access with wlan0, and I don't. The Belkin card's light flashes a little but I can't ping the router or the internet. What have I forgotten?
Thanks loads

give it a DHCP IP:

dhclient wlan0

To make changes permanent across bootups, configure it with System->Administration->Networking.

Sorry to be such a dumb-ass. Most folks seem to be able to wlan0 working with a lot less hassle. I'd appreciate some more pointers, please.

do you need to turn on encryption/WEP or anything of that nature? Your wireless AP isn't talking to you.

reply to blound
One thing to keep to mind if the rtl8180 drivers on the main download page are unmaintained - in particular, if you are using Linux 2.6.12 or above, you will need to download and compile the sources from CVS. If you do, you also to grab the 80211 source from the same CVS too (or, from the main project.

reply to blound
Yes, amen to the CVS checkout... Their snapshots are fairly old...

They're also in a transition state to a new set of drivers based on the kernel's recently added 802.11 stack, so it may seem like no progress is being done, but rest assured they're working hard in the background.
