i have been a sonic fiber user for quite a few years for now, and i've always been relying on the company's advice, and that's how I got my 1st generation eero pro 3-piece. To be fair, it was working pretty well, and that's without hesitation I upgraded it to a eero pro 6 3-piece during pre-ordering for $600+. However, while I am reading so many posts about being able to reach 700+ Mbps via iphone, I am standing in front of my gateway eero and only getting 300 Mbps max. Sometimes it might even drop below 100 Mbps.. Please advise what I can do to improve this situation..
