5ghz stopped working on Smart Hub 2

As the title suggests my hub appears to no longer provide a Wi-Fi connection on the 5ghz band. I’ve got FTTP with the 500 speed and previously all my devices, phones and iPads would connect to the 5ghz with speeds varying around the 2-300 mark. I noticed the other day that internet pages were slow to load and on investigation it turned out that every device had switched to the 2.4 band with speeds down to 30 or so. Now I know that it’s the device that chooses the band to connect to but it seems that the 5ghz is no longer available. I went into the hub manager and turned off the 2.4 band thinking that would force my devices onto 5ghz but nothing would connect, phones, iPads or laptop, even when I stood right next to the hub. I couldn’t even get into the hub manger to turn the 2.4 back on and had to dig out a Ethernet cable to connect direct.

A Wi-Fi analyser show the 5ghz as present but nothing will connect. Has anybody got any suggestions for sorting this? Is it likely that the hub itself is goosed.

I'd try a full factory reset by holding the little button on the back down until the light turns green, (about 30 sec). Just be aware, this will drop the hub back to defaults, so any custom setting will need to be put in again. You can export the settings and then reload them again, however.

If that doesn't work, the hub is bricked. Ring customer services for a replacement. 0330 1234 150

Should have known the old IT trick off turning off and on again would do the trick. 5ghz back, iPad connecting at 481 Mbps 🤷‍♂️ thanks all

It's not a trick.

A restart clears a lot of minor glitches. In industry you rarely have time to investigate the cause and only usually do so in the event of a recurring problem. Everybody thinks "turn it off and turn it back on again" is a joke. Actually, it's not.

Glad you're sorted anyway.
