Sometimes it's ~3 days after a reboot; other times it's ~10 days, give or take a few days. It's rare it stays alive for more than 14 days.
This is truly unusual. (First time I have seen this particular situation in almost six years on the forum.)
Would it be convenient to post a screen shot of the browser error message?
Is the web page being accessed by URL (htto://orbilogin.net ) or by the IP address of the router?
No response no matter which browser is used?
wow.
A screenshot of a browser unable to connect to an unresponsive service would not be enlightening.
Other data points:
- the Orbi app is also unable to connect to the router when it’s in this state
- all satellites remain responsive; browsing their admin pages works fine
- neither DNS nor browser choice is the issue (testing w/ telnet to router IP address yields same results)
Plainly put, the router’s admin service (or stack) dies after N days. Hard power cycle resurrects functionality…until another N days.

You have managed to enable telnet on this router? The last I heard Netgear had removed telnet from all Orbi models.
Multiple browsers. Multiple computers. Both http (port 80) and https (port 443) and all the usual web pages:
http://<ip of orbi>/hidden_info.htm
All simply "time out" - no response at all.
That TP-Liink system looks like quite a deal. 6E, Parental Controls, for $289.99 Would probably want to spend some time on their user forum. We know all about the shortcomings of the products we have, and close to zero about other brands.

There are ports other than just 23. 😉 But you're right, I should have clarified (mostly port 80). However, this gave me an idea...
All nodes have latest firmware, V4.6.14.3. The satellites all report:
Server: lighttpd/1.4.58Lo and behold: https://www.cvedetails.com/cve/CVE-2022-41556/
A resource leak in gw_backend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of mod_fastcgi is, for example, affected. This is fixed in 1.4.67.Who knows if this is the smoking gun, but it's certainly suspicious.
How does one submit a Bug Report or Feature Request to Netgear, in order to get lighttpd upgraded to at least 1.4.67?
The posted questions is a working strategy for us here in the forums as everyone's environment, configuration and such differs, greatly sometimes. So we don't know or have any kind of knowledge to what most users have or have done. Reason for asking these questions. Helps us gain a better understanding of what users have and have deployed and in use. Any thing and everything could effect something in different ways. Also not everyone sees the same issue. Someone just posted the other day of seeing 19+ days of good time time on there system. So I would not categorize your issue as seen by others.
Seems like if you don't want to help us out here by giving feedback to the questions presented, then I would recommend making contact with NG support and get there help on this. Possible you may have a faulty unit. Also would be helpful to NG to know what maybe happening so they can fix it if this is a FW issue. Something to ask them about.
