Re: RBR850 WAN stuck on 100m/full
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 intern...
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. Changing DNS servers has nothing to do with WAN connection rate at all.
I probably should have asked when the WAN speed dropped from gigabit to 100MFull.
Since it may be a day or so before the replacement router arrives, it might be entertaining to perform the typical troubleshooting steps:
- 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. 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.
- we went through all of those things except the loopback test. The same exact cabling plugged into the back of my ancient iMac gave One gigabit up and down immediately. Put it back in the router and you got 100 Mb per second.
The jack looked clean on the router but it’s hard to tell if it’s broken or not visually.
my wife and I both have jobs going where continuous on interrupted Internet is crucial for monitoring situations so downtime as at a very high premium in my home. I don’t think I’ll be doing any troubleshooting for fun as I don’t want to get yelled at the rest of the evening and have to sleep outside.Thanks. Glad that Netgear did a thorough job looking at the problem. Hope the replacement router restores full service.
- this is a second home on the Georgia coast so sometime during our last two weeklong absence is when the speeds went from normal to 100 megs. There are a lot of lightning storms here and a lot of voltage drops as the electricity is relatively unreliable compared to American cities. Everything is plugged into battery backups with a whole house generator but the voltage routinely fluctuates +/ -5 to 8 V.
