After looking at the link posted, then If it is a wifi only issue, on a Hub3, you can try separating the SSID's of the 2.4 and 5 GHz wifi bands by renaming them in the settings and at the same time switch off "channel optimisation" apply and save the settings. All wifi devices will need reconnecting to the best SSID at each location. Also use a wifi scanning App to find the best wifi channels to use (just select and use channels 1,6,11 on 2.4GHz) - this often helps Hub3 users get better wifi performance - but its still no substitute for getting better kit 🙂
To address the wif issuesi, 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.
