How do I stay on n41 band on my trash can?

The way to trigger the bug is to save the admin authentication to the browser. Then go into the admin account to say the 2.4G or 5G wifi configuration and make a change. Say you change the max users from 128 to 64 and then save. When you back out of that config level then a prompt window to save your password pops. It may have the username empty or it might be 64 or 128 depending upon the max user value. The password with be auto filled with your WPA key you have associated with the SSID for the given wifi network. Like you would ever do that? It is a stinker as once the browser gets the info you can't use it to authenticate to the router unless you remove that from the browser. The only way the browser can get that is from the router. So, I am 100% convinced the 0338 code is the culprit as I have never seen that behavior till my router upgraded to that software version. (Just in case you stumble into it.)
