zd1211rw mesh speed limited at 1Mbit?

[petrivir]

Hi,

we are testing a mesh network with open80211s (www.o11s.org) in a wireless-testing kernel. We are using A-link WL54USB adapters with the zd1211rw driver. Mesh seems to work fine, but the connection is established only with 1Mbit/s (~80kb/s transfer rates with FTP). When using adapters in "regular" WLAN, we were able to get much faster speeds (7-10Mbit).

Is this a driver feature? Is it possible to increase speed in mesh mode?

Thanks in advance,
- Petri Virkkala

Sorry for the double post.

Here's the result of "sudo iw dev mesh station dump" in a two link mesh network:

Station xx:xx:xx:xx:xx:xx (on mesh)
        inactive time: 64 ms
        rx bytes: 5699474
        rx packets: 9166
        tx bytes: 253024
        tx packets: 2597
        tx bitrate: 1.0 MBit/s
        mesh llid: 29759
        mesh plid: 28168
        mesh plink: ESTAB

"tx bitrate" is here 1.0MBit/s as we suspected. Is there a way to change/force it to faster speeds?
