Okay, this just gets even stranger.
I had some downloads that required me to leave the computer on overnight & when doing a speedtest after those downloads completed, I was at 18MB down without the router & 17.7MB down with it. No changes were made between uses to the router, however does this router need to "warm up?"
The only difference between the prior tests & this morning were that in the prior tests the router had been off for a full day (completely unplugged), where as the test this morning was after a night of being completely powered on... Again I ask, what gives?
