Using the principle of the lan repeater on one of my GL-B2200s, I made it into a repeater with synchronisation via wire.
Not long ago I discovered that the guest wifi works very strangely. When I connect a smartphone to it, the latter writes that the Internet is not available. At the same time, I can use telegram, instagram, signal and youtube without any problems. As soon as I open chrome on my phone, I can't get anywhere.
At first I thought that the problem was in the firewall and rebuilt the access point according to the instructions on the website:
But it didn't help at all. I have a very remote idea of what exactly the problem is and would appreciate it if you could explain to me where I've messed up.
