I am currently deploying a combo of 1532E's (root and non-root) at some of my remote locations. The distance between units would be on average of around 1000 feet. Of the 6 locations that I have deployed this solution, only two have been of a non issue. The others however have been a serious problem. I'm using the exact same configuration on all units. Each are running on only the 5Ghz radio. I'm passing around 7 VLANs via sub interfaces on gi0 and dot11r1 interfaces. I am also using a standard AES-PSK-WPA2 authentication method between the units. DFS is being used for channel assignments. The antenna being used is a AIR-ANT5114P2M-N. The issue that I'm running into at the other 4 locations is that every 4 to 5 days or so we begin getting complaints that communication is broken between systems sitting behind each roo/nonroot bridge. Upon further investigation, I see that the wireless bridge units are still associated and talking, but packets show that they are being randomly dropped. It will stay this way until I shut / no shut the root antenna. I have also changed code, implemented a local 802.1x EAP-Fast Authentication method, but no changes.
I'm no novice with wireless, but I want to see what your thoughts are on what could be causing this. Have you experienced anything similar? Any ideas?
