PPPoE disconnecting without any reason

Hi there, Im experiencing some big problem here. My PPPoE clients randomly disconnect and after some seconds connects again. Some of my APs at clients dont connect again and I have to go to the client and power down the APs so they connect again. I also set the KeepAlive to 500 to see if it helps but instead it just make the same client appear many times at Active Connections. Anything Im missing here? Thx in advance!

Hi there, I have figured out the problem. Well, the actual problem was in the wireless interfaces bridged after the PPPoE concentrator, it was droping the clients and reconnecting after a while making the PPPoE drops also. Thats because of some misplaced configuration I did using HW retries and Frame lifetime settings that proved to not work as I expected. Anyway thanks for anyone reading this topic and trying to figure it out. Cya around guys!
