Upgraded today to superhub, and speed upped to 30MB.
Beforehand, speedtests were showing around 17MB by wifi, 19 cabled. Fine. 2MB upspeed for both.
Afterwards, speedtests are showing around 12MB by wifi, around 30 cabled, 3MB upspeed for both.

Tried explaining this to Indian callcentre but went off script so no resolution or explanation, just a reboot.
Lots of reboots done.
Any ideas, anyone?
