After talking to my SE and one of the Engineers in the Wireless BU they have
confirmed that 7.0.116.0 is indeed MR1, and they are calling 7.0.98.218 MR

Meru:
- What version of code are you running
Just upgraded to 4.0-150. So far it seems fine. It resolved the administration
interface lock ups we were seeing.
- What style of AP's do you use
We have mix of 208's and 311's.
- Do you use different style access points within the same air
Hi all,
I am currently troubleshooting an issue in one of our residence halls that
appears to be related to some kind of non-802.11 wireless device. Cognio (now
Cisco of course :) ) Spectrum Expert shows an unknown 2.4 GHz device, sometimes
taking up to 90% of the duty cycle on seemingly
We have seen wireless headphones kill the entire 2.4GHz spectrum.

It sounds like a frequency hopping spread spectrum (FHSS) device, something
that expects uninterrupted connectivity.- usually associated with a phone.
It could also be a wireless game controller, wireless speakers, etc.
Do you have a directional antenna for your Cognio? Time to go on a treasure
We see this across all channels at over 100% capacity around our football
stadium during football games. It is caused by the Wireless cameras to local
(non-network) TV satellite uplink trucks. I doubt that you are having this

Radio control cars and airplanes use FHSS on 2.4 Ghz also. Exactly how the
frequencies are chosen depends on manufacturers. Airplane transmitters are for
up to 1.5 miles and usually around 100 mw.
