Gary, after reading all of the above, I'm betting that your speed fall-offs have nothing to do with any routing issues.
It's probably that the main Internet speed coming from your provider is falling off whenever too many folks around you using the same provider are online - just like the average 120 Mbps from my provider can drop down to 50-60 Mbps whenever too many of my neighbors are streaming from the same provider.
OP has DSL, sounds like you have Cable Internet..
Not the same at all.
DSL, absolutely no one "shares" the OPs line, it goes all the way back to the phone Co's central office. The central office then connects the OPs line to the Internet.
Now with Cable Internet, that IS a different beast, Cable company uses large long "loops" of cable, puts bunches of folks on each loop.. Cable Internet can suffer from over crowding on the loops as more and more folks get on which will indeed slow down the Internet access for all on that loop..
OP has verified via a direct hardwired connection that their DSL modem/router IS getting the speed that they are paying for and the Phone company was to provide.
The OPs issue is not the phone company's side, it is something wrong with their router/ Wifi access point which is built into the phone company provided DSL modem/router/WiFi access point..
Phone company is sending them a replacement modem/router.
