We had an oversight on a project today and did not get the necessary cabling to configure our new radios for 802.11n. Regardless, I need to get the link up today and configure "N" later. Is there a doc on how to configure the sR71 to use only one antenna? The far end radio is using a cm9. Not sure if that makes a difference as far as enabled features.

set for 802.11 bgn..

Set for only one chain.

Connect ant to primary connector..

It will connect to the far end (802.11g) just fine..

I wasn't been able to make it work without MIMO.

Strange...

I run the SR71e.. I use both chains, (two Ant), but B,G,N all connect just fine...

I will try it with one chain disabled and take a look..
