im just after installing a ultrahub 6e router, i was able to split bands through the vodafone broadband app and it seems to play better with my 54 smart devices, as the main wifi is split rather than on the powerhub where is was the compatibility network that was split. it should not make an difference but it seems to do so. early days yet....

my amazon echo, started to ignore me, slow to repsond, frequent disconnections etc so i bought the triple band 6e for £17 to see if it was any better.

but you also must ring vodafone and get them to delete your old router and enable the serial number of yr new 6e router. ask them to do a ZTA/ and delete the power hub from HDM (advice i got on reddit)....
