The main issue with the Hub3 is that for many customers in "challenging" wifi environments, is the its wif is simpel just not good enough.
Assuming your wired connections are all ok then as VM don’t “guarantee” speeds over wifi (only ethernet cables) they only now supply “wifi pods” (not “boosters”). These are free to customers on the 1GB or Ultimate Oomph packages, and so are worth trying if you are on one of those.
Otherwise, you will be charged £5/month - and at that level of investment you would soon pay off that cost by buying your own better quality wireless equipment (not extenders) which will solve any wifi issues permanently, and will be transferable to other BB suppliers kit should you move supplier.
Get either a…
(1) Mesh System, (2) Wireless router, (3) Wireless access point or (4) A combination of (2) & (3).
