Poor WAN-LAN on r7000

I recently picked up an r7000 to take advantage of my 150mb down speeds that I have with my ISP. After I went ahead and did the basic install (including all updates), I went over speedtest.net and discovered that my down speed was capped at about 93mbps. I then connected directly into the cable modem and ran the test again, and received a better number -- 140mbps. I did this several times throughout the day and received consistent results: On the r7000, I was not able to get above 95mbps for download speeds. Is there something that I was supposed to configure on the router to achieve 890mbps WAN-LAN performance, as was stated in the SNB review? There's no wireless involved with this test, since I'm just plugging directly into LAN port 1 and then plugging directly into my cable modem.

Notably, the NIC reports 1000mbps Full Duplex on both (directly to cable modem/directly to r7000).

Thanks in advance.

Is the modem just a modem? (Hint: can you put it in bridge mode?).

Have you tried flashing the official firmware again and doing a full reset to defaults and without configuring anything else see if you get the rated speeds from your ISP?

If the above two ideas don't work; just swap for a different unit and if it's the same I would guess it's some interaction with your ISP + modem + R7000 + specific firmware that is available now. At that point I would try a different manufacturer.

What WAN connection method is the R7000 using?

It's possible that the R7000 isn't negotiating a Gigabit connection with the cable modem. Unfortunately, the R7000 doesn't provide any indication of WAN link rate or allow it to be forced.

I'm using a Ubee DDM3513 Cable modem. That seems to be the issue. When I connect directly to the modem, I can log into the cable modem management web interface and it states that the connection negotiated is 1000mbps full duplex on ethernet. When I plug the r7000 into the cable modem, it negotiates 100mbps full duplex. I'm using the same cable, so I wonder why this is happening.... Since you stated that there wasn't a way to force this on stock firmware, I'll have to try Kong's DD-WRT firmware to see if I can force negotiation to 1000mbps. Hopefully that's an option, otherwise I guess I'll have to return this.

Sometimes chipsets / drivers / firmware are incompatible. Can you force the speed on the cable modem end?

Update:

I ended up flashing the router with Kong's DD-WRT to force 1000mbps. This didn't do anything, and refused to talk to the cable modem. For the hell of it, I had a 30ft cat5e cable laying around that I swapped in and voila, it negotiated 1gbps.

Ok -- So I thought the issue was my cat6 cable. Thankfully I have a lot of cables here. I tried three different cat6 cables (of all various lengths), and it dropped back to 100mbps for each one.

Ok -- So now I'm thinking it's related to cat6 cables, no problem, I have many more cat5e cables to try. I tried the one that came with the r7000 and then the one that came with my cable modem, and then several other ones of various lengths and got the same result: All dropped back to 100mbps.

At this point I'm only able to consistently get 1000mbps with this old (and long) cat5e cable that I just happened to have laying around. Now I'm very confused....

I should note that I've tested all the cables fine, they can talk 1000mbps between other devices. I even started trying cables going from my PC to the r7000 LAN ports and they all negotiated 1000mbps fine. Why can this "special" cable only get to talk 1000mbps between cable modem and r7000 WAN? I can't figure out whether to blame (and return) the r7000 or the cable modem here. Is it worth RMAing the r7000?

It's probably the cable length that is doing the trick, not CAT5e/6. Either the Cable modem or the R7000 doesn't like the signal it gets with shorter cables.

Could be a bad R7000 or just an incompatibility between it and your cable modem brand. Either way, you need to decide what to do.

Sorry to revive a really old post, I'm from Chile and I have the exactly same issue, could you please provide more information for the cable that allow the 1gb communication between the router and the "modem".

Best regards.

You may be able to add a switch in between the modem and WAN port of the R7000 to solve the problem.

Where I can get a decent and low cost switch with 1 gb ports?

So, I bought the switch... for my surprise the ONT still communicate at 100 mb (with the switch)... the WAN port on the router communicate at 1gb now (with the switch), so the issue is for sure the ONT, I'll call the company to check if they can force the 1gb communication.

BTW, the switch that I bought is a Tplink® Switch 05b TL-SG1005D 10/100/1000

It looks like the default IP address is 192.168.100.1 for the Ubee DDM3513 Cable modem . You may be able to look on the web page yourself.

Not sure about that, the ONT model is edgecore gg 11000

Your right. I looked back to the first of the thread and you picked up in the middle.

Surprises after surprises, I just connect my laptop (wich I'm sure that is 1gb ethernet capable)m directly to the ONT, then I create the PPPoE connection, and the connection is still 100mb... so this has to be a configuration issue on the ONT, I have like three days looking for information regarding that ONT and I was unable to find something..., when the fiber tech came to install the service, he connected to the ONT directly and using the console he access to the device... I really need that information, thank you for reading me.
