R7000 throughput issue

[clintorion]

I just bought and set up the R7000 connected to a ARRIS Surfboard SB6121 with Comcast / XFINITY as my ISP.

Directly wired to my modem I get 90Mbps down, but as soon as I connect (LAN and WLAN) through my router I get ~10Mbps up and down (http://www.speedtest.net/my-result/4752160794).

I factory reset my router, upgraded to the latest firmware 1.0.4.30_1.1.67.

QoS is disabled.

I'm using cat6 cables between modem/router and router/computer.

Any ideas?

try this beta fw as it has nothing to do with stable fw. but just to see if the problem fixed.

Hey, thanks for the link. I tried upgrading to the beta firmware, but no changes. Still 10/10.

I also tried downgrading to 1.0.3.24 (which I read somewhere helped somebody), but that did not help either.

Update: I added my old router (TP-Link WR841N) as a simple switch between my modem and my R7000 and now it's is getting full throughput when connecting to the R7000 wireless connection. I really don't want to have my old router as a crutch here, but I hope it helps diagnose the issue.

You could try entering your Tp-Link WAN MAC in your r7000.

setup...internet setup ...use this MAC.

reboot modem and router

Thanks for the suggestion searay. Copied the MAC from my old tp-link and set up the r7000 to use it, rebooted, but still 10/10 speed.

In Show Statistics the WAN port should say 1000M/Full if not try another cable.

So you're saying the modem link light is Blue using TP link and Amber using r7000 is that correct?

[clintorion]

Hmm, it's actually showing 10M/Full. I've tried many cables, including brand new cat6's that I bought, as well as the cat5e that came with the nighthawk. 

Lights are always white-ish blue, no amber, even with the TP-link between the modem and my r7000.

What color is the Modem link light with TP and with r7000

[clintorion]

Sorry I misunderstood your question.

Reset the modem, plugged in tp-link: modem link light is amber.

Reset the modem, plugged in r7000, modem link light is also amber.

Used a cat6 at first, then repeated with the cat5e the r7000 came with, same result: both amber.

Based on your most recent response I believe your Modem's WAN port is set to 10 100 not 1000M. Check the modem's manual and or call your ISP. Depending on your package AKA Download speed having it at 1000m wouldn't make a difference. Cat 5 will work fine, in most cases it only makes a difference when the lengths get close to the limit. I doubt you're run is even close to that limit somewhere around 270~300 if I remember correctly.

Thanks for the help, ended up buying a new modem which solved the problem. 🙂
