MESH only works at 54Mbps link rate or below?

MESH only works at 54Mbps link rate or below?

[Bin Zeng]

Hi

I created a MESH network by using 802.11n supported cards, however, MESH only works at 54Mbps link rate or below.

Can anyone tell me how to active the 802.11n ht mode in mesh?

Thanks!

Just set the channel type to HT, something like:

iw wlan0 set channel 1 HT20

Before joining the mesh.

Thomas,

Yes, I did like that.
iw phy phy0 interface add mesh0 type mp mesh_id mymesh
iw dev mesh0 set channel 48 HT20
ifconfig mesh0 up

However, if I use iw to set bitrate, something like that "iw mesh0 set 
bitrates legacy-5 54 mcs-5 15". Then use "iw dev mesh0 station dump" to 
check bitrate. It seems like only show 54Mbps or below bitrates. HT mcs 
rate can not be controlled?


Any help appreciate.

Thanks,

Bin

I haven't tried this myself, but I believe the bitrates only affect
the rate control algorithm.  Do you see higher rates if you omit the
'iw set bitrates' command?

'iw set bitrates' should probably also be issued before bringing up the mesh.
