My Netgear WG511 drops it connection, say, after a day to the router. The green light goes from steady to flashing, and there is not connection. I have to go through the command line sequence to get it to reconnect. Is there any way I can find out whats making it drop like this? Ive got another laptop connected to the same access point with no problems. I am running Mandrake 10.1.

I've had my wireless die more frequently; it was a problem with IRQ interrupts. I passed append "acpi=noirq" to LILO and the problem stopped.

I have acpi running now, will that affect how it runs? Or is there another way I can go about disabling it?

Passing acpi=noirq to the kernel makes the wireless card useless in this case.

Bump

Just curious, what firmware (and maybe what method) are you using?

I found that the Prism54.org firmware (.arm file) had some odd behavior (would never connect with WEP). The Netgear supplied .arm file is working like a champ.

What driver (.o or .ko) module is referenced in /etc/modprobe.conf?

See if any of this info at my site helps: http://www.sonnik.com/archives/000030.html (if you need the other arm file, you can get it here...)

For some reason, I don't think it's IRQ's or anything...

What kind of encryption are you using?
Are you using iwconfig at the command line?

I will try your .arm file. I am using 128 bit encryption, but it was working fine before. I am also using iwconfig at the prompt as well

Ok, posting back after almost a day and a half of uptime, and still working like a champ. Apparently, the problem does lie in the .arm files, since the one I got off of sonnik's website has been golden thus far.

Good to hear. Hope the problem is completely gone for you now.
