Roku Streaming Stick wont connect to the internet.
Since you get intermittent connection, I am thinking that the router may be using DFS channels on the 5ghz band. The Roku devices cannot see or use DFS channels (52-140) so either need to Disable DFS use or manually assign a channel 36-48 or 149-161 under the 5ghz "Wireless Settings".
Since you had two bands to choose from previously (2.4ghz and 5ghz), and now you only have one, I am assuming the 2.4ghz may have been disabled. If the router had been placed into a "mesh mode", the device should be trying to connect to the 2.4ghz if the 5ghz is unavailable due to DFS usage.
If you can get some details from your son what he did, and post back with the Router model number and your ISP (internet service provider), can hopefully get you back up and running. You likely will have to login to your router (or use the accompanying app, if applicable), so good idea to get some info from your son as well on this so you know how to access the settings when provided.

Basically, need to know if the router has been placed into a mesh mode or if the 2.4ghz radio has been disabled for starters.
Feel free to post an update.
