I have setup quite a few GL-MT300N-V2 modems for people running nord accounts. I decided to create a backup image so it would save me the hassle of having to go through all the setup and settings everytime I had a new GL-MT300N-V2 to setup. Instead I could just restore my backup image. Once i restore the backup and try to access the router through 192.168.8.1 it asks for a password but the original password I set which should have been installed with backup image doesn’t work and neither does the password I set before the router backup was restored.
This should work for you.
Thanks for your help. I will try it out.
