So having 50M as a backup for my 80M FTTC lasted about 3-4 Months. Then I had an accident involving the Live chat on the VM website.

Also 802.11ac rocks, that speeds great for wireless
Just hope they were correct when they told me changing speeds doesn't affect my contract end date.
Now I probably have to replace the power-line link between my SH2 and my main router (That speedtest was wireless direct to the SH2)
Edit:
Apparently I don't need to replace the power-line link
