Hi we currently live in a ground floor flat it’s very long and narrow. We have one booster currently half way down the the property which extends us to the end of the house but we want to extend it even further to a summerhouse about another 40ft is something like this possible after we’ve already extended it once.
Are you "wedded" to wifi? If not - the best way to extend your network connections is to run an ethernet cable - connected to the Hub - out to the summerhouse and then add a wireless access point/switch combo on the other end in there - so you have excellent wifi as well as other ethernet connections available.
Not sure if another VM booster is possible or would help - it's certainly not a good idea if you have to pay the £3/mo fee - if free then may be worth a go.
It might be possible/better to use a Mesh wifi ststem (your own!) to do this. One unit connects to the Hub, then one half way down the house and then the third as close to the summerhouse as possible and lined up with as few obstructions (walls etc) as possible in the line of sight.
