I have an old router with the version 2.9 at a remote location where I do not have physical access at this time (I connect to it with Wi-Fi). I have been wanting to upgrade it to a 3.x version for a while but I'm afraid about losing the wireless settings and being unable to reconnect to it. Could someone who has done a 2.9 to 3.x upgrade please tell me if wireless settings will persist or need to be reconfigured?

The interface is at 5ghz-turbo without nstreme, manual tx power with no_country_set and no encryption.

Thanks in advance.

Hi, I just upgraded from 2.9 to 3.30 and all the settings were preserved.

Excellent, thanks a lot for the info .
