Re: [zd1211-devs] Problem with MTU > 500

[Ernst J. O. <ern...@eu...>]

Most relevant line from dmesg I presume:

zd1211rw 1-2:1.0: zd1211b chip 0ace:1215 v4810 high 00-25-86 MAXIM_NEW RF 
pa0 -7--

I opened the stick and there is a genuine Atheros AR2524 (= Zydas ZD1211b) 
and ubec UW2453 (RF) in it.

Same with the msi stick, don't know about the other, but it also has toe 
0ace:1215 vid/pid.

Hmm, what's the hardware (the zd1211rw: ... line in your dmesg, you can 
probably just grep zd1211 /var/log/message for it as well) may be all the 
same. There are quite a few variants.

I don't know if putting compat-wireless on will help, but you could give 
that a try. FWIW, the driver development has gone over to
linux-wireless.org and changes goes directly into wireless-testing git; the 
sourceforge zd1211 site isn't much more than the mailing list these days, 
and even the mailing list isn't very active. (try the linux-wireless list 
may be a good idea).
