I read that they are now setting 145 as the default unless you're on the 100Mb service.
Nope default is always 300mbps but any technicians that come to your home to set up the superhub should always change it to 145mbps no matter what service.
300mbps is not stable when connecting to 802.11.n cards so if you want to use 300mbps unless you have your hub sent through the post you have to change it to that yourself
does the virgin engineer come inside the home to set up the router superhub etc ?
