I do give credit when it is due, but when it's bad I complain, and on this occasion it is a complaint.
On Saturday evening I had a new 3.0 hub fitted with all that went with it. Previous one was a 2ac. The engineers were excellent.
Downloaded the Connect app, checked bedroom WI-FI, very poor, told to order the booster, which is free to me. Back on the app, and eventually told the usual, Ooops we have a problem!
Now I have to add at this stage, that I find that in general my signal is worse than I had before, signal in bedroom, is very bad now, whereas before it was okish. I was able to use an i-pad, now it's nigh on impossible.
Unless anybody can help, I think I have made a mistake, unfortunately I have just signed up for another 18 month contract.
Call it in at 08.00 for the best chance of getting through.
The best solution as legacy1 said is to consider getting your own better quality wifi equipment ?
However, as the boosters are "free" to you they are worth a try. There are also some tweaks you can do to the Hub3 settings that might help the wifi performance - they do for some people. That is, disable "channel optimisation & rename/separate the 2.4/5 GHz network SSID's in the Hub's settings pages..
