My Roku Stick+ is connected (it says it is connected, and streaming works) but going to Settings > Network > Check connection, or Set up connection hangs looking for SSIDs.
Going to Advanced > Reset network, and setting up a WiFi connection after the automatic reboot works. It lists all of the SSIDs. Selecting one, entering the passphrase, will promptly connect. However, attempting to repeat the process, it hangs searching for SSIDs. Immediately after resetting the network connection and configuring it, successfully on the first try (it says connectivity is excellent), checking the WiFi (to get the Roku to report speed) fails searching.
I repeated this process again and connected to my other WiFi network (one is 2.4G with 2 Access Points each with one channel, and the other is 5G, with 2 Access Points and three channels total.
Checking WiFi worked up until sometime after July, 2024, and I have not changed my WiFi configuration, so I am guessing this is a recently introduced software problem.
I have a Roku Premier in the same room, which exhibited a similar problem, but rebooting without resetting the connection eliminated the problem.
The stick" is on Software version 13.14.4 build 1512-50.
