No. As far as BT's own settings go, the Smart Hub 2 does not let you give 2.4GHz and 5GHz separate network names, so devices see a single Wi-Fi network and the hub decides which band each one uses. If a streaming device keeps landing on the slower band, you have to work around it rather than flip a switch.
Quick answer: The Smart Hub 2 has no supported option to split its bands. The practical workarounds are to move a stubborn device by temporarily turning off a band where your firmware allows it, to set channels manually, to run a cable, or to add your own router.
Menu options can differ between hub firmware versions, so treat the paths below as a guide.
Why would you want to split the bands?
5GHz is faster and less crowded, which suits a TV or box that streams live video. 2.4GHz reaches further through walls. With one shared name, a TV may stay on 2.4GHz after you have moved closer to the hub, or hop between bands and buffer.
Workaround 1: Nudge the device onto 5GHz
On the device, forget the network, stand it near the hub, and join again. Many devices pick 5GHz when the signal is strong. If your hub's advanced settings let you switch off 2.4GHz for a few minutes, the device has to join on 5GHz, and you can switch 2.4GHz back on afterwards. Not every firmware offers this, and anything you leave on 2.4GHz only (smart plugs, for example) will drop off while it is off.
Workaround 2: Smart Setup and manual channels
The hub's advanced settings include a feature called Smart Setup that chooses channels for you. Turning it off gives you manual control over the channel and width settings. That helps if your issue is crowding rather than band choice. It does not create two separate names. See router settings for streaming for sensible channel choices.
Workaround 3: Use a cable
If the TV is near the hub, or you can run a cable or use a wired access point, a wired link avoids the whole problem. See Wi-Fi versus Ethernet.
Workaround 4: Add your own router or access point
A second router or access point lets you set up a separate 5GHz-only network name, which is the cleanest way to force a TV onto 5GHz. Connect it to the hub by Ethernet and, if it will be a second Wi-Fi source, put it in access point mode (or a double-NAT setup if you must). Check BT's guidance on using your own equipment first, because the right method depends on your line type.
When is each option worth it?
| Situation | Best fix |
|---|---|
| One device stuck on 2.4GHz | Forget the network and rejoin close to the hub |
| Crowded flat with many networks | Manual channel selection |
| TV far from the hub | Wired access point |
| You want full control | Your own router or access point |
If that didn't work
Note your device, how far it is from the hub, and which band it is on. Many devices show the band and signal strength under their network settings. Don't post your Wi-Fi name or password.
