If you want a quiet life - do as legacy1 suggested on Saturday.
If it is just a wifi issue (are ethernet connections all ok?) then too address the wifi issues, VM now supply “wifi Pods” (not “boosters”).
Pods are free to “some customers” but most will be charged £5/month and right now they dont have enough supplies to provide them - unless you have a demonstrable wifi issue.
And at that level of investment you would soon pay off that cost by buying a "better" wireless solution that will be yours to own and use forever and which will cure all your wifi problems.
Get either a…
(1) Mesh System, (2) Wireless router, (3) Wireless access point (4) A combination of (2) & (3).
