Hi. This set up is based in hk.
Current hkt broadband is 1000M + 1000M speed.
From what I understand from the installation guy is its not a 2Gig line. More like there are two 1Gig lines. And if you aggregate it you get around 1.2.

I figure no harm trying dual WAN on this. Does that sound right or am I way off?

Currently leaning towards the asus axe7800 or tplink be550. Any thoughts or recommendations?

Very small place, range will not be an issue.
Priority on stability and speed.
