My file transfer speed has been poor for a while now and I borrowed a router to see if this was the source of the problems. Turns out it is. My file transfers with the superhub 2 start out at around 50-70mbs then tank to 11mbs. Normal performance is around a constant 80-90mbs which is what I was seeing with the borrowed router. My network is hardwired.
Another superhub wont connect to VM's network. So unless youve phoned in, they've agreed to provision it, (which they wont) youve brought it up and THEN tested, your still comparing, well you get the picture- there would have been no WAN load
SHOULD still function as a router, but how speeds would be affected with no WAN load is anyones guess
You could try 150 and convincing them you need a replacement , but it will be hard work... maybe if were *ahem* MORE broken it would be easier...
Or wait for staff on here to pick it up, they may be able to organise a replacement
