EAP245 wifi retries rate: how to reduce?
Hello! I have 11 EAP245's. They are generally doing fine, but one location has a very high retries rate.
Initially I thought that perhaps there is something wrong with the device, I swapped that with another one in somewhere, where there is usually nobody. But it didn't change: whatever I put in that location, it gets high retry rate. Obviously it's an environmental problem. I did run wifi-analyzer and so, I have 2Ghz band turned off, 5GHz only, chose 36 (if I choose "Auto", it picks 36 anyway), width 40. Tx power 28.
There is a crane near by, but the retries rate seems independent of whether the crane is in operation. There are wifis in the neighborhood, but the signal strength is at most -85 or so, and it's all 2G, as far as my laptop can detect. Besides, a few other APs' of mine are in the range to get the same interference, but they are doing fine.
All the other APs have "flat" retries. There is no drop or error at all.
Is there anything I should try? I would appreciate your suggestions!
