This is an unrelated (?) problem to what I described in my other post.

My situation is pretty unusual: I have a tiny PC called eBox-2300 that
runs at 200Mhz. This PC is running Puppy Linux with a kernel.
The box has USB 1.1 ports.

I mostly got a  LINKSKEY LKW-G750 USB adapter to work with WPA
encryption, BUT I see extremely high latencies when I ping a nearby
computer. Ping times are on the order of 100-10000 ms, compared to 0.5
ms when using a wired connection. This makes the wireless connection
all but unusable.

Using wireshark, I see one possible culprit for the problem: ACKs are
sent by the adapter with a delay of ~2 ms, compared with 0.2 ms for my
other cards. This probably causes a timeout.

Another clue is these messages from dmesg:

TKIP: replay detected: STA=00:13:10:86:90:39 previous TSC 000000000012
received TSC 000000000012
TKIP: replay detected: STA=00:13:10:86:90:39 previous TSC 000000000015
received TSC 000000000015
TKIP: replay detected: STA=00:13:10:86:90:39 previous TSC 000000000017
received TSC 000000000017

I wonder if anyone has seen anything similar or knows of a solution.
Is zd1211rw expected to work with 200Mhz PCs? Is USB 1.1 well
supported? Am I out of luck with the kernel?
