Internet plan upgraded but still internet download speed has changed

Hello O2 Team,

Thanks a lot for upgrading the plan from O2 DSL Classic M to O2 my Home L.

I have O2 HomeBox 6641 and i did reset the WiFi Router after the upgrade. But strangely internet download speed is not crossing even 30Mbps. This was the speed i was getting with O2 DSL Classic M.

I have already checked o2 DSL availability check for my address and up to 250 Mbps is possible either with Cable or DSL connection.

Should i do something to get faster internet?

Thanks in advance!
