IF you notice from my original post, which I linked above, I clearly stated that I despise Charter/Spectrum for their PRICING, which IMO, is far too high for an "internet-only" account. I NEVER said I despise them for the speeds they stated, or what I was getting with the old router.
Also by the way, I never expected THIS high of a difference, just because of swapping the router with a new one, or I'd have tried it a long time ago. This TP-Link router did about 90% of the configuration automatically, AND, got it all perfect compared to my original Netgear router that had to have nearly everything configured manually, and in depth. It was a great router, but I got about 8 years out of it before it started acting up these last few weeks, so I can't complain too much. To boot, the new TP-Link router was 1/2 the cost of the Netgear.
There's only 1 single thing the new router can't do: It doesn't have a built-in USB print server capability, and I would have liked that. I have an older Brother laser printer that's USB only. So, I'll have to get a print server to handle that. Or maybe I'll get a network laser. Not sure I want to lay out that much money for one though.
