Mitchells FIBRE SUCKS!

i have now moved from my ADSL 4mb line to Mitchells Fibre 20mb line but i feel as thoug i have downgraded?

1. Can only have 6 devices connected to my wifi at 1 time? with adsl i could have 20?

2. I cant personalize my wifi name/SSID? i hate using this generic MF number and believe me nobody wants to use that and they ALL want to personalize their name.

3. i cant track my daily usage or change wifi password? MWEB says they cant access our routers

I would really like a response to this or hear how many other others are feeling this way
