Hello, Now the problem is gone. Seems that the ISP refused my router, based on unknown criteria. The criteria is unknown because: - Not really MAC address restriction: I have another D-Link router with OpenWrt and different MAC: Connect OK. - We clone MAC from old router (which is TP-Link 741 with stock firmware, has been set up since I used ISP's service) to new TP-Link 940 with OpenWrt installed: Timeout is gone, but failed to authenticate. - I revert 940 to stock firmware without cloning MAC: Cannot connect. - Revert 940 to stock firmware and clone MAC: Connect OK. - Reflash that 940 to OpenWrt and clone MAC: Connect OK. Don't know why flashed TP-Link need MAC clone, but D-Link needn't.
