Does anyone of You have the same expierience?
RB911G-5HPnD cannot connect to 10MHZ APs?
Are you using v6.2 ? Post full config from the wireless of CPE and AP
Hello Normis,
6.2 was not tested yet.
we have several 911 CPE to this AP connected

But with new shipment a connection to 10MHZ AP is not possible.
sorry forgott:
the CPE in the first post is connected to the AP.
tihs CPE will not connect to AP
if you scan it will not see any 10mhz AP we tried 5.23 - 5.25 an 6.0 + 6.1

I can confirm, our shipment of 911G-2HPnD came with 5.25 on them. If you scan with channel-width=10MHz, you get results containing APs on 20MHz channels, and it won’t associate to any APs on 10MHz channels.
Upgrading to 6.4 fixed the issue.
I noticed this with the Groove A 52. I think it had 5.23 or 5.24 as shipped, upgraded to 5.25 and 5MHz and 10MHz channels worked fine.
+++++SOLVED+++++++
This issue has been solved with ROS 6.2/6.3 on AP and client.
FYI this was in the changelog for 5.25
What’s new in 5.25 (2013-Apr-25 15:59):
*) wireless - update required when using small width channel RB2011 RB9xx
