Wifi and upload nightmare issues.
Across all our devices for the last 4 months wifi connected devices are intermittently not loading, they just drop off to mobile data or say connected no Internet. We are on the gig bundle. When doing Sam knows tests all looks fine but it's not. The engineers even experienced it when here. When doing speed test downloads speeds are fine but errors out on upload. Had 3 engineer visits, a new hub a new booster, One engineer said he found a ghost network. Even when all hubs etc where off still showing the network. It's driving us crazy, wifi tvs connect and seconds later lose the network again. As do all mobile devices, laptops etc... Any help or suggestions would be very much appreciated
