Connect to the router and alternate router??

The VM hubs, unless you have gone into the settings and changed it, transmit one SSID name (what you connect to WiFi with) for both the 2.4Ghz and 5Ghz band. Some devices do not like this. What seems to work for some people is to go into the settings on the hub (from a web browser go to 192.168.0.1 and logon, password on bottom of hub, it’s NOT the WiFi password) and disable the 5Ghz band. You should now be able to connect the problem device. Now go into the settings again an enable the 5Ghz band and all devices should now be able to function.

Can we double check... wat Hub model do you currently have?  Its not an old Superhub 1 is it ?

That old one only broadcasts on one frequency at a time

Yes go with a better router if your stuck put hub in modem mode for it

If you'd rather not have the hassle of altering your existing setup you could alternatively buy an access point, like below, that plugs into the HUB and runs at 2.4GHz natively:

It will use a different SSID that you can use for the device/s that require 2.4GHz.
