Will a Pace 5268AC Gateway & ALCATEL-LUCENT G-240G-A ONT support Gigabit Fiber?
I currently have U-Verse with 25M internet and Fiber to the Prem. I am interested in upgrading to 300M or even 1G internet but I want to be certain my current hardware will support it. As I mentioned in the title, I have a Pace 5268AC gateway and a Alcatel-Lucent G-240G-A ONT. I tried, a few years ago, to upgrade to 100M service. However, when AT&T activated the higher speed service, I wound up with no internet service at all. AT&T could not determine why the service did not work but claimed the hardware should have supported it so I ended up back at 25M. I'm hoping this problem is either resolved by now or a non-issue with 300M or 1G.
Also, does anyone know if 100M internet service requires the use of all four pairs of a Cat 5E cable (specifically from the ONT to the gateway)? I know gigabit networks do, but I thought T100 networks can get by with just two pairs.
