Question

Download speed 75Mbps becomes 45 when plugged into router

Aug 14, 2017 1:32PM PDT

I just got off the phone with Comcast because my download speed was about 45Mbps with ethernet cable plugged into router. I plugged the Ethernet cable directly into the modem and my speed now exceeded the 75Mbps that I am paying for. I have a Netgear N600 WNDR3400 router. I have tweaked settings on the router many different ways, but still the same results. I even researched the difference between a cat5e and cat6 Ethernet cable. Does anybody have any ideas on how I can get true download speed or close to it when the Ethernet cable is connected to the router instead of directly into the modem. I just bought a new Netgear DOCSIS 3.0 modem. They said my Motorola DOCSIS 3.0 was at EOL, but that's crap. Thanks. Jay @ HP software engineer.

thanks, firmware is current, I know you lose speed when you stick another device in the middle, but it shouldn't be 1/2 the speed. Thanks again.

Router

What else/who else is using this router?

Is there a setting in the router to turn off wifi?
If so turn it off and test.

As a test.

Be sure no other connections and WiFi is off. Again, I don't know your settings, possible wiring issues (homemade cables always show up on speed complaints.)

I use better routers with dual core processors now so I rarely see that effect.

I always use other than the ISP or router for the DNS. That's been discussed why. Older routers like this one are well known to not pass much more than a few 10's of megabits. Those old routers were fine years ago since no one had 25 and up megabit links.

The usual final answer. Older router, only 100megabit ports
