RX too short data frame payload

Postby Fitzcarraldo » Tue Jun 24, 2008 16:28

I'm in a hotel at the moment and the WiFi network flies under Windows XP but runs like a dog with three legs under SL.

If I use Ctrl-Alt-F12 to see what is gong on, there are quite a few messages "eth1: RX too short data frame payload". eth1 is the Intel PRO/Wireless 3945 card in my laptop. I'm using the 2.6.25-r1 SL kernel and the iwl3945 driver built into the kernel (the microcode installed on my laptop is net-wireless/iwl3945-ucode-2.14.1.5, which is the latest version).

Anyone else with the Intel PRO/Wireless 3945 card and iwl3945 built into the kernel (not the iwlwifi module, which is hard masked in Portage) seeing this behaviour?

(Yet another example of 'progress' making things worse. The deprecated ipw3945 module worked like a charm.)

There is very little information on the interweb regarding this, it seems to be mostly related to ubuntu based distros, users have reported limited success by limiting the rate (to something low like 5.5mbps)

Yes, I've read those Web pages too, but I'm not sure that's the solution because the problem seems to happen with some WiFi networks but not others.

Although it pertains to the hard-masked iwlwifi module, as opposed to the iwl3945 driver built-in to the kernel, this problem was apparently fixed in November 2007:

So perhaps there is still a problem with the iwl3945-ucode-2.14.1.5 microcode that was released in July 2007.

EDIT: Doing an "iwconfig eth1 rate 5.5M auto" does help a bit, though.
