I've been noticing a lot lately that my phone and tablet are switching from 2g to 5g even when near to my Superhub 2. It's sometimes easier to switch off the wifi completely and let the page load up on mobile data. Then manually change it to 5g again.
This is very annoying and far from ideal.
Does anyone have any suggestions on how to stop this happening please?
I reboot the Superhub 2 regularly, so I don't think switching it off and back on again is the answer (the only technical one I know!)
Your router broadcasts 2 frequencies, 2.4ghz gives you better coverage and 5ghz is a faster frequency
The way it works is that the router will swap between both these frequencies if you have previously connected to both so to prevent your devices swapping back and forth, just forget the 5ghz network on the device and stay on the 2.4ghz. Once you forget the network if you wanted to rejoin it you would need to re-enter the password.
Hope this helps
I am a virginmedia employee but all opinions are my own.
The SH will broadcast on the 2.4Ghz band and the 5Ghz band simultaneously.
Your wireless clients will scan for possible target APs for a stronger signal, if the current signal is deterioating, this is known as roaming. If the 2.4Ghz and 5Ghz have the same SSID, switching between the two should be seamless and you should not experience any problems. Roaming is a client decision and has nothing to do with the hub.
It may be worth checking the roaming settings on your tablet and phone, setting them to the lowest setting or turn off if possible. Changing SSID \ Password on the non-desirable frequency may help as Legacy stated or disassociating the non- desirable frequency as greeniegirl as said.
I would use WPA2 with AES encryption on the hub to prevent any encryption issues during handoff, as WPA auto can sometimes cause a bit of confusion.
