So when the Sales guy had come, I had noticed that he was saying that another and pricier ONT will have to be purchased in order to get speeds above 50Mbps, he said the other ONT for faster than 50Mbps speeds is "DUAL BAND". I did not give it much thought back then but I took the "DUAL BAND" as something to do with Fiber connectivity and not as "Wifi Dual Band" - which is actually the case.
So @
murtaza12 , you got HG8245Q2 as they must have suggested with Dual-Band Wifi and I got the simple HG8245H model. Just out of curiosity, I ended up looking specification sheets for both ONTs today. It looks like there's literally no difference in the ONTs other than the Q2 being Dual Band and a lot heavier (which might explain why its running cooler, perhaps heatsinks? - unless that's the wrong weight, lol. 1500 Grams!
Anyhow, I am posting the Specification sheets side by side below. As can be confirmed, there's no difference between the two so this hopefully means that it will support whatever speeds TES will bring up in future, even if its 100Mbps+? (Which officially looks more like 2 Gbps downlink and 1Gbps uplink - certainly more than 50Mbps that I was informed the first one supports...
