Not getting full AT&T fiber speed
I installed the ATT fiber internet today in my apartment. I was pretty excited to see how the 1GBPs internet works but turns out it is slower than the previous one I had from Spectrum. The speed test is barely giving me 100mbps download and around 200mbps upload speed. I am having a problem loading up 1080p youtube videos.
The router they installed is BGW210, and I also have U-Verse but right now, it is not in use. How do I fix this internet speed? I am only getting 10% of what I am supposed to get.
