Sorry to hear about it. Mine broke on me while I was thousands of miles away from it.
The gui and the ease of configuration was what attracted me to the product at first. But if the product is unreliable, sometimes you have to do it yourself -> I've already built out a replacement vpn server with raspi 4 and the speeds are pretty good, especially since I can dedicate cpu cores to wireguard.
I hope GLiNet notifies me when they or if they fix this issue. The MT2500A is in the junk drawer in the meantime.
