RE: [WIRELESS-LAN] Strange Cisco AP problem
All, 7.0.116.0 is also available, though you could also wait for the 7.0MR1, which according to Cisco will be released in May 2011.

I moved back to his room and it still would not function. I reset the AP and then it started working. I would say well it comes down to a simple reset but having several connections that are working fine and several connections that are not working all on the same AP is concerning. I have about 3 locations on campus that are experiencing this same behavior. I have rebooted them but it still seems to be having the
Re: [WIRELESS-LAN] MERU wireless
Thanks for all the great feedback, it is appreciated. I have another question regarding coexisting. Did anyone have Meru and Cisco running at the same time and what issues did you see. Obviously with our current state of funding we can't fork-lift replace our entire Cisco wireless system so they would need to coexist for the duration of funding the replacements.

Re: [WIRELESS-LAN] MERU wireless
I have Meru running along side Cisco and 5G access points without any issues. As I introduce Meru APs, I perform a site survey and try and use a channel not being used by the Cisco APs. I still use the Meru single-cell architecture as I complete each building and phase out all the older gear. I hope this helps,-- Jason R.

Re: [WIRELESS-LAN] Strange Cisco AP problem
Anyone running 7.0.116.0, have you played with the Office Extend Feature? I've had a NAT bug filed against it, and it states that it's resolved in 7.0.116.0, but has not further details. (It's classified as a bug, but it was more of a design defect, and I'm wondering how they fixed it.)
