2.4GHz not working

[volcane_uk]

Hello, Our vodafone router will not connect to any devices on the 2.4Ghz setting, (5Ghz works fine).

I have split the SSID's and tried just about every trick in the book to connect the printer, wifes mobile and a games console to the 2.4Ghz frequency and none of them will connect. 

I have factory reset the router several times, added MAC addresses, tried static ip's plus other options and nothing works.

Do I have a faulty router?

Thanks.

Maybe it's faulty, maybe it's not!

First up, a nice little utility you can load on to your mobile (or tablet) called WiFi Analyser.  It's not an in depth tool, but at least you'll be able to see if the 2.4GHz radio on the router is actually transmitting.

If you find the router is not transmitting, in the expert settings you can try assigning it to a specific channel rather than "auto".  *Just doing this will reset the 2.4GHz radio, so it should work for a little while at least.

Finally, rather than typing in the password, use the WPS feature.

See how that all goes, and let us on the forum know how you got on!

According to WiFi Analyser we do have a 2.4ghz signal coming out of the router. 

I tried changing the channel too but still didnt work.

Seems no device is getting an ip address from the router and just won't connect to the 2.4ghz wifi.

I used my phone which connects to the 5GHz with no problems and tried to connect to the 2.4 GHz and it wouldn't connect either so it seems its definately an issue with the router.

Yup, if you are using the EXACT same SSID and everything on 5GHz and 2.4GHz and one will connect and the other won't then it does kind of suggest that it's an issue with your particular modem/router.

It's tech support time I'm afraid - good luck!

I have the same problem. I've expected a faulty router but as we have the same issue and it started at similar time I'm not so sure. Have you had any luck with it or have you contacted support? 

[volcane_uk]

No, no luck so far. I'm going to contact TechSupport today and see what happens.

Please. let me know what will be the outcome. I'm away from home at the moment and don't want to waste time with them.

Thanks.

I need help with this too please. I have the exact same issue. Randomly wifi stopped working for a bunch of devices and splitting the network i can see its all those on 2.4ghz that cannot connect, 5Ghz is fine.

I have tried everything, factory rest etc, but something is clearly broken.

As a workaround I have connected the router to my extender via a cable, and connect the 2.4ghz devices to that.... 

Please can you help.
