About remote management, does the pcWRT router have a public IP address? If you are not sure, please send a screenshot of the Status page to [email protected].
There are no WiFi related changes in v1.22.2, so in theory there shouldn’t be any changes to WiFi behavior. Is WiFi channel on Auto? If so, you might want to select a specific channel where WiFi interference is the least and see if that makes things better. You can download a WiFi analyzer app on your phone to find out which channel is the best.
If you are familiar with command line tools, you can ssh into the router to look at the system log and do other things. Use the command ‘logread’ to see the system logs.
