Just teasing about you being rude
The offers that retentions can make change all the time. It will also help if you are out of contract or they have just announced a price increase and can leave penalty free.
I think all of the previous free speed boosts have suffered delays and been pushed back from their original estimated dates. So I was expecting this, which is why I spoke to retentions back in January. Well that and the price increase. I'm sure there will be small print that makes it clear they are only estimated dates.
I have the SH2 and getting 200Mbps speeds in modem mode with a Netgear R7000 router, so you don't need a new hub.
