D-Link (DWL-G122 rev.C) Wifi USB Adapter keeps dropping connection in Ubuntu Hardy
 

Hi guys,

Am having some trouble with my newly purchased D-Link Wireless Dongle. When I plug it into my laptop, it activates and I am able to see the wireless networks in network manager (And WICD which I installed but didn't resolve problem)

After selecting the network and typing in my network key it connects fine, but then completely deactivates after a couple of seconds. If I continue unplugging and plugging it in, eventually one of the attempts will work and it will stay on, but that can sometimes take over 10-15 tries. The messages in the system log are:

Also, not sure if it's relevant but there is one line in the system log that keeps repeating every 10 seconds

Any help will be much appreciated.

How bizarre - 'PHY' is the physical layer - if this were a wired NIC, that would be like the driver always complaining that you don't have a cable plugged in.

This type of problem is often caused by a spurious interrupt - do you see any 'spurious interrupt' messages?

One thing to try (though not guaranteed to work) is to disable the apic, lapic, or if you're really desperate and have super-buggy hardware, disable both. So try booting with the following set of kernel parameters and see if one fixes your problem:

noapic lapic
nolapic apic
noapic nolapic

One other possibility is that the setup scripts are just screwed - did you search the Ubuntu forum to see if other people have reported that problem?

Hi and thanks for the reply!

Unfortunately my laptop's hardware is already so ridiculously incompatible with linux that I am already having to use noapic and acpi=off simply to boot the OS (not just Ubuntu - same is true for every distro I've tried so far). Even more unfortunate, the addition of the nolapic argument to the boot script has not resolved the problem.

I'm currently writing this reply from my desktop and unfortunately I have no net connection on my laptop right now, so I shall follow this message up with the outputs of a few commands once I wire up the laptop to my router. If anyone can suggest any other outputs that would help diagnose the problem, please let me know.

I have also asked about this problem on the Ubuntuforums and the Ubuntu IRC channel but unfortunately I'm so far coming up blank.

Thanks again for the reply

OK - here's the outputs.

(this first one is obviously before the USB adapter shuts itself off - once that happens it disappears from lsusb. Also, I've tested other USB devices (e.g Printer/Mouse) in the ports and they work fine, so confident it's not the ports themselves causing trouble)

Would really appreciate any help people can provide!

Oh - one more thing - this time I wasn't getting this line:

Jul 8 10:33:40 m1dn1ght-laptop kernel: [ 617.604917] eth0: PHY reset until link up.

So that was either a temporary glitch, or stopped because the ethernet cable was plugged in. At any rate, the problem continue unabated, so that was probably not the problem :(
