R7000P WAN Port at 100M instead of 1000M
My cable provider just upgraded my inbound connection to fiber, so I signed up for 300M download, but I'm not seeing it. I have a Cable Modem CM1000 Purchased 2017-07-14 connected with a CAT-6 cable ...
Yesterday I received the GS305 1Gbps switch and placed it between the CM1000 and the R7000P. Unfortunately it did not fix this issue. This evening as suggested I downgraded the R7000P firmware to 1.3.0.20, did a hard factory reset, manually configured and examined the WAN port. It was still at 100Mbps speed. I then upgraded to firmware 1.3.1.64 and retested. Same results. To date I have swapped out all of the CAT6 cables, inserted a 1Gbps switch, performed hard factory resets and still there is nothing I can do to get the R7000P WAN port to auto-detect a 1000Mbps speed. I have taken pictures that document the results of each test. I've attached a PNG file that shows the Show Statistics screen along with the final negotiation state with and without the GS305 switch. My final conclusion is that I have a defective R7000P. Contacting Netgear support didn't do anything to resolve this issue because my hardware warranty expired 9 weeks ago. The event that led me to this discovery was my cable provider installing fiber-optic cable, which encouraged me to pay for upgrading my throughput speed. Sadly if that had happened three months earlier, I would have discovered this problem while the R7000P was still under waranty. I am left with a defective product and my only recourse is to replace this router to be able to attain throughput greater than 100Mbps.
Try placing a Gigabit switch between the modem and router. It can sometimes solve such an issue
I appreciate the suggestion of trying a 1G switch between the modem and the router. However, that doesn't answer my question. The CM1000 has a 1G Ethernet LAN port and the R7000P has a 1G Ethernet internet port. When I connect these two ports with a CAT-6 cable, my expectation as a 30-year IT professional is that 1G throughput will be the result. If not, then one or the other is not performing to its specifications. In fact, on page 12 of the R7000P manual it states that its internet port is "One Gigabit Ethernet RJ-45 WAN port to connect the router to a cable modem." It doesn't say anything about needing a switch between the cable modem and the router, and since both are Netgear products, they should work together as advertised. So, my question remains. Is there a known solution to this issue or is it a design issue on either the CM1000 or the R7000P?
I wouldn't put a switch inbetween the router----modem. Its a good way for someone to plug into the switch and end up with connection issues.
the goal is to figure out which device is causing the issue.
I'd start by taking a known good ethernet cable and connecting a pc/laptop with gigabit directly to the modem.
a. what lights do you get?
b. What speeds do you get? maybe the lights not displaying properly
c. try different cables just in case "known good' isn't.
I've seen crud in ports cause issues with 100mbps vs 1gig connection. have you powered the devices down and checked/cleaned the ports if needed?
Yes, all of the troubleshooting has been done multiple times. I've done a factory reset on both CM1000 and R7000P. I've powered them up in the correct sequence. I've swapped out CAT6 cables to prove all cables are working. When I directly connect my PC to the CM1000 with CAT6 cable and do a speed test (fast.com per Netgear Support), I get 330Mbps. When I then connect the CM1000 to the R7000P and the R7000P to my PC with CAT6 cables and do the same speed test, I get 94Mbps. I am convinced that there is a product defect in the R7000P that prevents its WAN port from performing to specification. If anyone has any information to the contrary, please speak up.
It actually fails Auto-negotiation between router and modem. I used to have an old Arris modem that did this. No matter what I did, it got stuck at 100 Mbps. Placed a small Gigabit switch between router & modem and got my full 1 Gbps negotiation. I'm not sure whether in your case the R7000 or the modem is to blame, that's why I suggested a switch between (also from past experience). If it works/solves the problem, then the R7000 and the modem fail correct Auto-negotiation
