On Sky LLU you can't use the BTwholesale checker, so you have to remember what speed they said you would get when you signed up.
I can't remember what they said.
I used the address checker as XRaySpeX suggested. I can't find image tags to post the image of what that displays into this post, so I have uploaded it to tiny pic. Link to that info is below:-
On both the SR101 and SR102 routers you should have the speed displayed that you are connected at. It can't tell you what you might get, and if its worth upgrading from the £20 service (a max of 40/10) to the £30 Pro service (a max of 80/20).
Details of that info are below:-
Modem Status Connected
DownStream Connection Speed 40000
UpStream Connection Speed 9996
I am only get approx. 20Mbps at present Downstream.
There was something unusual I now recall at the install. I had to set WPA/WPA2-PSK mixed mode Security Encryption to get it to connect on my PC, (was fine with default settings on my wife's PC).
