Two weeks ago I had a problem where my rental modem randomly factory resetted itself. They sent a tech over and he called xfinity and they did something on their end which has caused my speeds to fluctuate between 400mbps and 930mbps, on every wired device despite usually getting a solid 930 always. They said everything looks good on their and called it a day.
So 3 days ago I go pick up a new modem since tech support said it would fix my fluctuations, and not only did it not fix it but now I have problems loading 4chan. I even tried changing back the modem and the problem remained. Now at random times no board will load until I let it sit at loading for 30 seconds. Then it loads normally until it randomly happens again.
