Intel wireless adapter packet loss with N mode enabled

We are running 7210 controllers in an AP105 environment with OS 6.2.1.5 and are haivng issues with our clients that have Intel adapters. We have about 135 AP's installed and about 100 wireless med carts throughout our hospital. We are seeing freezing, slow response and packet loss with n mode enabled. Ping tests show a dropped ping just about every 8 pings. If we disable n mode on the client adapter, they run stable and no longer freeze or lose pings. We are using Intel driver 15.11.0.7 from January 2014 . Anyone else seeing problems with Intel adapters or have any insight to this issue? Thanks.

If you haven't opened a case, please do so. Thanks

Vinster,

 

What operating system, what type of encryption are you using on the wireless?  Are any other devices using this same wireless with these symptoms?

Most of our devices are IBM/Lenovo with Intel adapters. I haven't heard of any issues with Apple devices. The OS is Windows 7 and we are using WPA2 with certificate (machine auth) on a 2008 R2 server.

Re: Intel wireless adapter packet loss with N mode enabled

Are you enabling/disabling "N" mode in the Intel Driver?

I will, I'm just in the middle of an unrelated VPN/Firewall issue at the moment and cannot spend a few hours on the phone with tech support right now. Since we are up and running, I just figured I'd post the question to see if anyone else was seeing this. Thanks.

We have a few different models, mostly Centrino N105, 6200 AGN, and 7260.

Okay,

 

Do you have "Bonded" channels or 40mhz channels where the channels on the access points show up as 36+ or 40-?
