RAX200 - WPS light continues blinking. Already tried rebooting.

Per the findings of others on this thread, when using the RAX200 with Firmware Version 1.0.2.8, if you press the WPS LED button and it starts blinking, it continues blinking indefinitely.  If you are able to get the WPS LED back to a solid state by reverting to an older version of the firmware or completing a factory reset, the next time you press the WPS LED button, the WPS LED is back to a state of blinking indefinitely.  After multiple hours of testing during a Chat session with Netgear, I was eventually told that our testing indicated it might be an issue with firmware and that they will be escalating it to the concerned team to work upon.

The testing that eventually seemed to indicate an issue was as follows (which starts while the router is at Firmware Version 1.0.2.8):

1. Obtain Firmware Version 1.0.1.12
   1. Navigate to https://www.netgear.com/support/
   2. Enter RAX200 and select RAX200 – Nighthawk Tri-Band AX12 12-Stream WiFi Router / RAX200
   3. Click Downloads
   4. Under Firmware and Software Downloads, click + View Previous Versions
   5. Click FirmWare Version 1.0.1.12
   6. Click Download
   7. Extract the contents of the downloaded RAX200-V1.0.1.12_1.0.41.zip to a folder (including RAX200-V1.0.1.12_1.0.41.chk and RAX200-V1.0.1.12_1.0.41_Release_Notes.html)
2. Revert to Older Firmware Version 1.0.1.12
   1. While on a device connected to the router network, log into the router at http://www.routerlogin.net using the admin user account
   2. Click on the ADVANCED tab
   3. Click on Administration +
   4. Click on Router Update
   5. Click the Browse button
   6. Select the RAX200-V1.0.1.12_1.0.41.chk file where the content of the zip file were extracted
   7. Click Upload
   8. At All existing Internet connections will be terminated, click OK
   9. At Warning! The firmware version you are trying to upload is older than the one you had., click Continue
   10. At The router is updating its firmware and then The router is rebooting.  It might take up to two minutes for your changes to take effect., wait for the router to reboot
3. Verify Blinking Issue Does Not Occur
   1. After the router has rebooted, click the WPS LED that is solid
   2. Verify the WPS LED starts blinking
   3. After five minutes passes, verify the WPS LED stops blinking
4. Update to Latest Firmware
   1. While on a device connected to the router network, log into the router at http://www.routerlogin.net using the admin user account
   2. Click on A router firmware upgrade is available.
   3. Under Firmware Update Assistant, at Do you want to update the firmware?, click Yes
   4. At The router is updating its firmware and then The router is rebooting.  It might take up to two minutes for your changes to take effect., wait for the router to reboot.
5. Verify Blinking Issue Does Occur
   1. After the router has rebooted, click the WPS LED that is solid.
   2. Verify the WPS LED starts blinking
   3. After five minutes passes, verify the WPS LED continues to blink

After this testing, to get the WPS LED to remain solid, I followed only steps 1 through 4 above and will avoid pressing the WPS LED button again until after there is hopefully a firmware update that addresses the issue. 

A couple side notes:

• After updating back to the Latest Firmware in step 4 above, I seemed to more quickly be able to access the Internet from a device that was connected to the router network than I was able to log back into the router at http://www.routerlogin.net.  When trying this the first time, I powered the router off and then back on again to resolve the issue, but it was taken care of a subsequent time by just waiting a little longer.
• When first troubleshooting the issue, while I was using the latest firmware and my WPS LED was indefinitely blinking, I used the Back Up option (ADVANCED tab -> Administration -> Backup Settings -> Back Up) to save a cfg file to my computer.  After completing a factory reset of the router, the WPS LED was solid.  As soon as I used the Restore option (ADVANCED tab -> Administration -> Backup Settings -> Restore) and the router rebooted, the WPS LED started blinking indefinitely (without me pressing the WPS LED button).  It seems like the state where the WPS LED is blinking indefinitely is saved in the cfg file.
