Yesterday, I plugged in the lAN flylead between my router, the TP-MR3220, and type the IP 192.168.0.1, and was promptly asked for a password, which I had long forgotten. So, I thought a quick factory reset would reset it to 'admin' again.
Thing is, I can no longer reach the device. It's like it's changed IP address. I even went and bought a new flylead, in case that one was faulty. What could cause this sudden withdrawal? Oh yes, after the reset, only the power light on the very left was on, and a lock-looking light on the very right.
