Re: RBR850 WAN stuck on 100m/full

Question

I have the same exact problem with an RBR850 where the Wan port is stuck at 100/full.
I got all the way up through level two tech-support at Netgear until the guy finally decided it must be an internal hardware issue and they arranged an RMA to replace it.
This router was already a replacement router for unknown hardware issues with the first RBR850 router that I had been using for about three years.
It’s very frustrating.

I am jumping into this late, but I have seen networks working perfectly but low speeds. Have you examined your modem, I didn't see where you said the model of modem you have. And are you able to examine the power levels and signal-noise ratio of the download channels on the modem on its debug page? I suspect you have 32 download channels if you have 1GB service.&nbsp;I suspect your SNR should be in the 40s, 42-44, on every channel to get 1 GB. If you have even 4-5 channels on 32-36 dBmV for their SNR, you will not get 1GB download speeds even if the modem reports no errors.&nbsp;Just wondering if you have checked this?

Wow.&nbsp; Did you purchase an extended warranty?
&nbsp;
Please post how things work out with the RMA unit.&nbsp; Would you mind describing the tests Level II support went through. i.e.

swapping cables?
connecting directly to the modem?
doing that fun loopback test suggested by plemans in message 10?

level one tech had me factory reset the router after backing up the configuration settings and then reinitialize from start up, and restore the configuration settings.
He also asked me to change the DNS servers to some dummy numbers all eights and a couple of fours. And we went from WPA to WPA two/ WPA three security protocols.
The level three tech guy just had me do the router reset without returning the back up configuration settings and just looked at the statistics for the WAN still being stuck at 100 Mb/Full And decided it was an internal hardware problem and nothing else could be done.
The first replacement router I purchased on my own to solve the other problems I was having. This began to happen inside the 90 day hardware warranty for the new router so I was able to exchange it for a small fee. I have not received the new router yet.

I should add that the router and satellites all worked perfectly during this entire affair except that they were capped at 100 Mb per second.

Doesn't seem (to me) like Netgear support did much for you.&nbsp; Changing DNS servers has nothing to do with WAN connection rate at all.
&nbsp;
I probably should have asked when the WAN speed dropped from gigabit to 100MFull.
&nbsp;
Since it may be a day or so before the replacement router arrives, it might be entertaining to perform the typical troubleshooting steps:
&nbsp;

Pull the WAN cable and examine the RJ45 jacks on both ends for any bent wires. Gigabit connection requires all four pairs of wire to be connected correctly.&nbsp; 100Mbps requires only two pairs.
Swap the cable for a different cable.
Connect a computer/laptop directly to the modem in place of the router to see if it connects at gigabit. (This is becoming more difficult as fewer customers own a device that has an Ethernet port.)
Doing the loopback test between the WAN port and one of the LAN ports.
