tried Tenda , no solution. Both my system log and LCO's app shows unauthorized mac. Onu in route mode should have worked because that is what I have been using for past 1 month. Even after that it worked in bridge mode for 10 days. No issue at all. The ip resets every 24 hour at midnight. Fiber gave me another credential and guess what it worked. Bridge mode doesn't work , system log says port binding failed and it is stuck on chap(bridge mode).
