  1. thanks. i thought username : admin will be full access to the gateway. that why i didn’t find the way to change the DNS setting. yeah finally i found it. appreciated you share it here.

  2. The UniFi connection in my house is not stable resulting in intermittent lagging. I tested my device in the vendor shop and there is no lagging at all. My router is trg212m. Would appreciate your advice.
    Will a firmware upgrade resolve the problem? Is there any firmware upgrade for trg212m?
    Thank you.

  3. i forget my dns password, and i cnt find it anywhere…is there any way to login to the front page?

  4. Operator password not working for me also. Something seems broken with dns also, connections only working when I manually use static DNS.
