Well, yeah, I'm not wondering about that at all. The first order of business is getting my speed back up to something close to the 50/15 I saw before this adventure started today.
Now, here's a weird thing. I've been running these tests all day from a laptop on my 5 GHz wifi. I know that's not a precise way to measure, but it should be good enough to see if I'm in the ballpark. After all, the original 50/15 measurement was on the same link.
I ran the dslreports test from my phone (cellular turned off) connected to the same 5 GHz wifi. It reports anywhere from 60-80 mbps download speeds. So, I ran a cable from the laptop to the router and tested again.
Come on, now. I'd be amazed if my 50/15 link were over-provisioned for 315 mbps!
