rax120 keeps locking me out of internet

Continuing battle to maintain a consistent wireless connection with internet. My PC is connected by ethernet, with no issue, but the wireless continues to show no internet. The Router is broadcasting a strong signal, but is locking me out until I eventualy connect remotely with Nighthawk app. This is every day, and the remote option takes 10- 20 minutes at least to resolve. Any ideas? I'm about to toss this garbage.

Thanks,
