Speed drop if going through a router, fine if wired direct from modem

I have a Docsis 3.0 motorola modem (provided by Spectrum). If I connect the ethernet from the modem direct to my PC, i immediately get full bandwidth, 120 Mbps, on all speedtests (fast.com etc). However, if I first go to my router, then ethernet to the PC, the speed drops to around 55 or 60 Mb. An important note here is that this combo has worked fine for several years. Same modem, same ethernet cable, same router. (I say that because it illustrates the older router, cable, and modem are capable of full my full bandwidth) This issue just popped up yesterday (Apr 20)

The oddity here is that purchasing and trying a brand new router with all the latest tech renders the exact same results. 55 to 60 Mb speed. The tests are very very consistent. Always the same each time, no variation. Same goes for wiring direct from modem to PC. Always 120 Mb.

The upload speed is always 100% good. Both direct to PC and through both routers, 12 Mb up.

The 55-60 speed (wired) is consistent on 3 different PC's in the house. Two are Win10, one is an older Win7 laptop. And I got that speed on the other PC's with the new router as well.


Here's what I've tried so far:

• rebooting modem & router & PC (several times each)
• different ethernet cable from modem to router and to PC (same results)
• 2nd, brand new router (same results)
• disconnected all wires from modem (coax, ethernet, power) and re-connected
• read through this thread. My symptom is similar, (120 --> 60 drop, download only), however I don't think it's relevant, because I get full speed as I should if I go direct from modem to PC ethernet in. If it were a software issue, I would think that would persist direct wired or via a router. Either way, none of the fixes in that thread helped me.
• updated older router's firmware to latest, though even that update was from 4 years ago.

Thanks for any and all suggestions!

 

Use modem/router combo as router only

You more than likely can't. The input side of the modem/router combination is going to be exclusively the modem.

Also trying to get your modem/router working on the cable system, did the technician press the reset button on your modem/router? I had an issue with my daughter's cable internet where the modem just would not connect. Finally after about 15 minutes, I just pressed the reset button on the modem/router to clear all the old settings out from the old ISP and it just magically connected to the new ISP!

 

Do I Need A New Router?

No combo. Line goes into modem, from that a router is connected. Did a direct connection to the modem and all was good. However when using wireless off of the router, all goes to hell.
