I wondered if my Edgerouter Lite would be able to cope with my connection so set it up today to give it a blast and sure enough the little guy is quite happy with the BT Fiber 900/100 connection acting as a PPPoE controller.
I even load balanced it with a 4G connection from Three so I could see a 986mb download speed and a healthy 178mb upload speed.
The CPU wasn't maxed out either which I was quite impressed with but the single gigabit link to the main switch was pretty much leaking 1's and 0's onto the attic floor. Total saturation!
I turned off the 4G connection as it was pointless and I don't have QOS not because it's not something I require.
Personally I use a VPN on one machine and as it is software based it is quite happy at 5-600mb down and happy to use most of the upload but I don't have a need to use a VPN on the actual wider network.
All in all I'm happy I've got to remove the BT super hub from my network. Just a shame the ONT's dont have native POE otherwise it'd be POEPPPoE (I've got injectors so technically I do have that)
BT Fiber - 920 down, 100 up.
