replace bt fibre modem.

[#1]

Hi all is it possible to replace the bt fibre modem for a all in one modem /router like a netgear.

[#2]

yes, it is.  There is no reason to keep the OR modem if you don't want it

[#3]

Yes it certainly is.
I use an ASUS DSL-AC68U. Some people prefer Billion or Draytek  models and I'm sure there are different advantages/disadvantages to them all.

Thanks for the replys always used netgear so probably will stick with that type.
