so its router specific. Thats whymine is just 2.04 and the other is 2.8. Both look almost exactly the same via the web interface.
They may look the same but they are not.
The sky router here in Gorslas looks the same as mine in Merthyr, but the model numbers are different.
The interfaces look the same (mainly) but they are different models and I think the same attributes apply in the differences you are stating.
