Since we had the first issue like this we started using industrial cisco switches at each site with spanning tree on. That at least shuts the port off until we can find the bad radio instead of ruining the entire tower.

Just figured the static from the lightning messed with the radio. We have tried doing the firmware recovery procedure, but the problem continued even on the bench testing. It acted like someone plugged their router in backwards. Finally decided to just throw them in the trash figuring lightning damage was not covered under the warranty. We never investigated it any further.

The network is running really slow to no internet for customers after a lighting storm rolls thru. Ping an AP on the network and you get 2 reply then 2 timeouts 2 reply 2 timeouts repeatedly. Looking at the ARP table of the Mikrotik router for that network and one MAC is registered to a lot of ip addresses belonging to other equipment on the network (The device also announces that it owns the gateway also). Locate the device for that mac and log into that device, (keeping deleting the arp tables entries in order to get there) and Disable the LAN interface. I ARP stealing stops. Replacing the radio is the long term fix. This has happened quite a few times after lightning storms and across all the different devices made by Ubiquiti. Reloading or upgrading firmware has no effect. Today we had one on one network and two on a different network. With two of them it was even harder to fix. Had to MAC access deny the radios to get service restored on the network. Are we the only one with this issue? Has some one else had this issue and found a fix? -- Arthur Stephens Senior Sales Technician Ptera Wireless Inc.
