WiFi Channels, how do i change them?

[Bullfinch]

I have a vodafone thg3000. 

How and where can you change wifi channel on the above router? 

Logged into my router I go to WiFi tab at the top of the page, then select "WiFi Settings". 

Only choices I see 2.4 Ghz, wifi mode, mixed 802.11b/g/n

Bandwidth 20mhz

And 5 Ghz, mixed 802.11n/ac

Bandwidth 20/40/80 Mhz

There is no option to change channel. I ask as there are a few neighbours on vodafone internet too.

before connecting to voda, enable manual DNS and use a 3rd party dns provider that provides filtering. block vodafone domain. ta-da (maybe)

Its OK I have 2 vodafone ultra hubs, the one I posted was an unused spare for playing around with so it doesn't matter if anything happens to it....I can always create a PPPoE server on my mikrotik and see what happens

really baffling they disabled that monitoring, which was useful.
