Hi there,
The other week my TalkTalk Wifi Hub 2 updated to the latest firmware (SG4K100206), but this has caused an issue where the 2.5GHz band is permanently disabled. I have tried disabling and then enabling the band in settings and advanced settings, but it stays as Down or Disabled no matter how many times I do it.
This is problematic as my printer doesn't support 5GHz, and so is out of action until a solution can be found.
I have tried both restarting and factory resetting the router. Neither have solved the problem.
Any ideas? Is it possible to reverse the firmware update as it was working fine before?
