I've been trying to solve a problem with the wi-fi for weeks now, after firmware updates were applied to the Hub One routers. It messed up the dual band frequency, meaning that the 2.4GHz signal became weak, unstable and is frequently dropping out completely. After going through a careful process of elimination (inc. line check and new router, etc. etc.), it drives you mad to be asked the same questions over and over again by under-qualified customer service agents who basically fob you off (interference BS) and try to buy the tech team more time to fix it. I asked for a roll-back of the firmware before xmas and I am still waiting. Either they don't want to admit they have properly messed up the firmware for their product, or the team that is supposed to be sorting it is catastrophically under-staffed. If you take a look at the forums, there are loads of customers very upset at being let down and strung along, so my advice would be to steer clear if you have devices that use both 2.4 and 5GHz. A bag of trouble!
