I'm under the impression my ISP has decided to throttle me, as I'm unable to download anything without it being extremely slow and eventually failing. My phone's hotspot is faster than the Wi-Fi, yet it's also slow and fails. I have tried everything from my PC's end and don't think the issue lies there, thus leading me to believe it is the ISP's doing. I was looking forward to this, so I hope they aren't actively throttling me and it's something that'll blow over with some time, but it seems like an ISP change is in order... they constantly have these sorts of issues. My disappointment is immeasurable and my day is ruined.
(My ISP has been trying to get me to upgrade to a "higher-end" router, so I wouldn't put it past them as a marketing trick to make me believe the Wi-Fi I have now is insufficient.)
