RBR50 WAN stuck at 100mbps

[stickx911]

My rbr50 Wan port will not see anything higher than 100mbps. After trying every cat6 cable in the house, I tested AP mode and borrowing another moder/router and plugging into any other lan port, I get the 300 or so I'm supposed to see. I tried the Mirror lan 1 and using lan 1, but that didn't work as I'd hoped. Any other ideas before I start shopping?

So I know the modem isn't the issue.

The cable isn't the issue.

I have tried this on the latest firmware.

Using the RBR50's built in speed test. 

Is there anyway to force it to use 10/100/1000? A telnet command or something...? Everything else on this has met my needs and I would rather not have to replace it.

Using the web interface, click Advanced tab and then click the "Show Statistics" button.  Does this also show 100M/Full or does it show 1000M/Full for the WAN port?

Since you tested your cable and modem and verified they are working at gigabit speed with another modem, then your RBR50 may be defective.  If it is still under warranty, then contact Netgear support for an RMA.

You might also try a factory reset to see if that corrects the issue.  Save your configuration first so that you can restore it if needed, or at least take screenshots of each configuration screen that you customized settings on.  NG support may also request you to factory reset it as part of their troubleshooting process before issuing you an RMA.

FYI, I subsribe to 100Mb/s speed from my ISP, but my WAN connection to my modem is 1000M/Full.

Maybe it would useful to know exactly which modem/router the Orbi is connected to (brand and model number).  With more than one LAN port, it sounds like this is a router. (A topic for a different discussion.)

Frankly, I was a bit surprised to read what goes into gigabit ethernet autonegotiation:

http://www.ethermanage.com/ethernet/pdf/dell-auto-neg.pdf   This is WAY more complicated than I had expected.

It might be useful to look up the specs on the ISP device to see what it says about the LAN port standards.

Thanks for all the feedback! I was hesitant to do a wipe as I have a lot of things configured, but I suppose it's worth it before giving up all hope. 

Issue started (was first noticed) on a sb6183 and getting 300mbps plan last year. I always had ~50 before, so it wasn't a consern prior to. xfinity claimed it was because of docsis 3.0 so last month I bought a sb8200. Same results. xfinity came back and spent hours checking the cable lines and such before hooking up their xb6 combo modem/router and it worked.

I don't trust the cable company as I've had them pull these tricks on me before so I spent a day or so trying every manageable combonation and the only way orbi sees 300mbps internet is in ap mode using a different LAN port on the orbi instead of WAN. Can't use AP mode on the sb modems. 

I do not want to use the cable companys system because I like having a lot more control over my network. Extra fees kinda sucks too. Idk.

This seems very odd that WAN port is doing 100Mbps and LAN 3 is doing 100Mbps.  Just curious, remove cable from LAN 3, swap the cable connected to WAN port with the cable connected to LAN 1 or LAN 2 to see if WAN port changes to 1000Mbps.

moving the modem to port 3. same cable as was reading at 100 before.

3 was just a cheap POE camera setup with 10/100 (an IP camera switch). I removed it entirely here to at least test to see if it was bringing it down. That device also just shows 100 no matter what it's plugged into, but I'm pretty sure that one just doesnt have gigabit.

If you reconnect to WAN port (without the cheap POE connected to LAN 3) and it still says 100Mbps on the WAN port, I would find a paper clip and do hard reset, stick it in the back until it blinks amber.  Don't restore old config after reset!

The Arris Surfboard 8200 is a "modem", not a "router/modem".  So, it does not act as a DHCP server, handing out IP addresses.  This means the Orbi must  be in "router" mode for any devices connected to the Orbi to function.  The WAN (yellow) port on the Orbi is the only port that should be connected to the 8200.  If the link does not come up as 1000 Full, then you have to (a) try a Factory Reset, and if it fails to fix the situation, (b) contact Netgear for a replacement.

Ap mode was only useable with the xb6. I would just like to be able to return xfiniti’s modem/router and go back to mine. Sorry if I was confusing. I’m going to try the factory reset this evening and see what happens. I appreciate the response.
