Deco M5, printer not able to connect through wifi
I am trying to connect my printer through WiFi.
Before I installed the M5, it was no problem on my other router.
I gave the new M5 network the same name and password as before. Printer wouldn't connect, even though all my other devices did without a problem.
When I tried to connect using the printer, I would find the network on the printer. Tell it to connect. Wouldn't. So I reset the printer to factory settings. Tried to connect. Wouldn't. Printer doesn't ask for a password, just tries to connect after selecting network and tells me it cannot connect. Finally I tried turning of the 5Ghz on the M5. Now it would connect. Great. Then some things happened and I had to rename my network. So I tried to setup the printer again. Factory settings. Turn of 5Ghz. No connection.. Same problem. It won't ask for the WiFi password. Just tries to connect and then says it is not able to connect.
Now I have connected it by cable. This works. But I prefer to have it connected by WiFi so I can move my printer.
Also, my job is to go to people's homes and solve their computer problems. It would look a bit silly if I advice mesh and cannot install their printer...
So what is the problem here?
Please advice.
TIA
