2.4 or 5GHz?

I have the problem that I can't connect to the Wi-Fi network on my laptop. I found the solution to switch to 5 GHz but now I have the problem that my cell phone does not connect and I'm really slowly lost. I don't know my way around and I don't know what to do either

If other devices also fail to connect, it will be time for a new wireless router

If you have a lot of devices in your area in dense residential areas, signals can interfere with each other because there are simply too many Wi-Fi signals wandering around, so 5ghz helps because this has a shorter range

if your system throws out other devices, you either have too many devices or the system itself is crazy

This is the speed port from Telekom and is new, so I don't think it's because of the router. There are no other options

Other possibilities are unlikely if it affects multiple devices

I have the problem that I can't connect to the Wi-Fi network on my laptop

That means exactly what? What is happening? What is not happening Error message?

I found the solution to switch to 5 GHz

What are you switching? The setting on the wireless router? The network card? From which original setting?

But now I have the problem that my cell phone does not connect

Maybe because it doesn't support the 5 GHz band?

also don't know what to do

First of all, provide specific descriptions.

So first of all I have two laptops that cause problems. With the 1st connection to the network is not possible. I was able to fix this problem by switching the router to 5GHz but then my mobile phone could no longer connect with the message Can't connect to the network. The problem with the second laptop is that the internet is really very, very slow so that you can't work. When I do a speed test on my cell phone I'm at 70 Mbit, but when I do a speed test on the laptop that is charging for 100 years, something comes with 0 ,. Mbit and I do not understand that

After all, we now know that the mobile phone supports the 5 GHz band. I would first turn on both frequency bands on the router. Then I would delete the WLAN profile and create a new one on the devices that have problems.
