Was this resolved in v7 FW if you updated to it or is this problem still present in v7 FW?

re RBS firmware updates: when I originally did the firmware upgrade, I did the RBS units one at a time, using their own web interface. After the first RBS has the new firmware and had restared and synced with the RBR, I went to the next RBS and repeated the procedure. After all RBS firmware was upgrade, I did the RBR firmware upgrade for the first time.

I followed the procedure you suggested:

- disconnect my RBR from my wired network and set it to router mode

- factory reset using the software tool in Admin/Backup

- configure RBR and RBS from scratch while all disconnected from my wired network

- I was successfully able to login to the web interface of the RBR using https://orbilogin.net

- reapplied the 4.6.14.3 firmware update to the RBR

- still can log in using https://orbilogin.net

- change configuration of RBR to access point mode using a different known unused static IP address (10.10.10.251)

- unplug power to RBR. While it sits for 1 minute, I connect RBR to my wired ethernet network using a cable

- plug power in to RBR and wait for it to boot

- verify I can ping the RBR new IP address 10.10.10.251

- update my internal DNS to point ap1.example.com to 10.10.10.251

- try to load https://ap1.example.com, get HTTP 500 Internal Server Error

- try to load https://10.10.10.251, which works fine.

Now I'm pissed off, and I'm determined to track down this problem. First I unplug power to all by RBS satellites and leave them unplugged to remove complexity in the target configuration. I disconnect the RBR from my wired network and do a factory reset. Reconfigure it from scratch using the procedure outlined above, same result.

Then I downgrade the firmware on the RBR to 4.6.9.11, do a factory reset, and set it to AP mode with a static IP 10.10.10.251. Everything works fine, no HTTP 500 Internal Server Error. So I do another factory reset, and configure AP mode with a dynamic IP instead of a static one. It works fine that way too. My hypothesis is now that it's a problem with the firmware 4.6.14.3. So I install 4.6.14.3 on the RBR, configure AP mode with a dynamic IP address, and the HTTP 500 Internal Server Error is back. After more experimentation and exploration with more sophisticated command line tools (nmap, dig, curl), here's what I know.

The error is observed:

- using firmware 4.6.14.3 on an RBR850, but not using firmware 4.6.9.11

- configured in AP mode (doesn't matter whether you use a static IP or dynamic IP)

- access web interface using a hostname, not an IP address (obvs in AP mode the hostname has to be provided by something besides the RBR because in AP mode the RBR DNS server is off)

- when accessing either http://ap1.example.com or https://ap1.example.com ie the error occurs independent of whether the web connection is encrypted with TLS

- before the authentication prompt, ie the HTTP 500 Internal Server Error occurs before the RBR prompts for the administration credentials

- regardless of browser used. I have replicated the error using using Safari, Chrome, Firefox, and curl.

- whether there are RBS satellites connected or not

The error is not observed:

- in the Orbi app for iOS. The app seems to work fine in all configurations and firmware levels.

There are two workarounds:

1. access the web admin tools using the IP address, ie https://10.10.10.251 (or whatever the IP address you've given to your RBR, either statically or dynamically when enabling AP mode)

2. downgrade the firmware to 4.6.9.11.

My guess is that firmware version 4.6.14.3 for the RBR introduced an error in the web server configuration.

Thanks for your suggestions @FURRYe38 , but unless you can whisper in someone's ear and have them create a new version of the firmware, I don't think there is any way to fix this problem.

I upgraded to V7.2.6.21_5.0.20 last evening, and I still have the HTTP error 500 Internal Server Error when accessing the web ui via the hostname. It continues to work fine when accessing via the IP address.

If your not using the WAN port, possible reason why your seeing that 500 Internal error. If your not using the WAN port, you should be. As seen here: https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point

Just checking to see if this may have been resolved. Updating the bug with updated information if possible.
