I have been getting 1~3 connection drops recently throughout the day. I haven't had this problem before and I have tried everything I could think of from changing settings, checking wiring and reseting/factory restoring the router. The router is a MG7540 and its about 4 months old. I have uploaded a recent log of t3 errors.
