Hi
I just set up my deco X20 network and I have a 2.4 ghz problem.
My main network is set up with mesh 2.4 ghz and 5ghz and it works ok. But I need a network only with 2.4 ghz, as I have several devices that only run on 2.4 ghz network.
I have tried to make a guest network with only 2.4 ghz and it does not work at all. If I'm lucky I might be able to get a speed of 0.50 mbps. but sometimes I can do a speed test and then it shows 70 mbps.
I have a 500/500 connection and on my main network I hit 350-400 mbps on speed test.
why do I have such a bad connection at 2.4 ghz?

ps. i have tried running only 2.4 ghz on my main network and it gives the same result as on the guest network.
