2.4ghz not working

[Brewster82]

Had continued problems with Wi-Fi dropping and the range decreasing and dropping connection but full Wi-Fi. I have since split my Wi-Fi and have had no drops on 5ghz on any device, which fixed our mobile device issues. Both channels are active, smart optimization turned off, I cannot get anything to connect to 2.4ghz. I’ve reset it multiple times via pin hole before I split the WiFi to rule out any issues. I’m trying to set up a ring doorbell which requires 2.4, I have also tried my mobile devices and tv and other mobile devices in house to 2.4, not one will connect. I’ve changed password to rule out that issue but no joy. I’m needing the 2.4 to work. This is a hub 3, been rebooted so many times, that will not solve the issues, neither will a pin hole reset. I believe the 2.4 is the problem. New router time?

Try Client62's solution to a similar problem here...

Briefly disabling the 5GHz band forces the customer's mobile phone on to the 2.4GHz band, this means the IoT device and management app on the customer's mobile phone share the same list of SSIDs  only from the 2.4GHz Wi-Fi band.

In the case of Hub 5 there does appear to be a further issue that network traffic does not pass between the 2.4GHz band and the 5GHz band, this means the customer may not be able to connect to their 5GHz laptop / mobile to their 2.4GHz IoT or 2.4GHz Wireless Printer, the latter having caused dozens of problems where the customer has connected the printer but is now unable to use it. Quite a blunder on VM's part, but Hub 5 in Router mode really is a clunker.

I’ll try that and see how it goes. Thanks.

Am I glad my Hub 5 is in modem mode, and my printers are cabled.    😉

Just had chance to test this. Unfortuantly the 2.4 does not work on the hub 3, when the 5ghz is disabled. No devices will connect. I can see the ssid, but phones and laptops will not connect.

Have you tried a pin-hole reset of the hub, it has been known to fix the odd problem even when logically it should make no difference. 

[Brewster82]

Many pin hole resets have been done. We have had numerous issues with this router. Contract due to end in march, so looking at other options. Thanks for the suggestions.

It's very difficult to prove to VM that a "working" Hub is in fact faulty, and get it swapped out.  It would be better if the Hub had failed altogether.
