My Ethernet cable is indeed not connected to the cabinet: the cabinet is a . . cabinet (though made of metal) some distance from my house, and which serves various properties.
I do not know quite how to complete the schema that you exemplified with the following:
But perhaps like this:
Fiber > Cabinet > telephone wires > British Telecom 'OpenReach' modem, model (I think) 'B- Focus v-2FUb rev. B' > Ethernet (WAN) > RT-AC66U > Ethernet (LAN) > One Windows desktop (on Ethernet), two Linux laptops (on 5GHz wifi), one old Android phone (on 2.4GHz wifi). _________________ My router: Asus RT-AC66U
Operating systems on devices that I use with that router: GNU-Linux; Windows 10; Android 13

Google search shows that the BT OpenReach modem is indeed a DSL modem. Might check its log for any possible clues to your disconnects. Might also check with any local users support forums for additional info on your Internet setup. DSL signals are susceptible to RF interference, not just from radio station but even regular household electrical appliances such as microwave ovens. Need to methodically verify that your DSL connection is indeed stable and operating reliably first in order to isolate the cause of your disconnects. Good luck!

And this is just some of the web results. Lots of evil laughter included, but not sure if the OpenWRT information is helpful at all or if the modem is the one referred to. I didn't follow the paper trail to see if it actually still worked as a modem or not. At least now you can possibly figure out what your disconnect issues are caused by, perhaps?
Thank you both very much for your suggestions and links.
It seems that even to read the logs of the modem (as against router) is involved. If my recent aforementioned tweaks to the DD-WRT router settings don't do the job, I might either try and get a new modem from my service provider or else buy a replacement router from a company that was talked up on one of the linked pages, namely, ZxYEL. _________________ My router: Asus RT-AC66U

Thanks. That sounds a good idea. However, after some looking around - in my DD-WRT settings and on the 'net - I cannot find a way to find the attenuation value. _________________ My router: Asus RT-AC66U

Thanks. I had seen that rather overwhelming (and sub-optimally written) page before. I took another look at it.
Some port scanning and some Internet searching suggested some possible IPs for the modem (IPs valud even when the modem remains in its usual setup, i.e. not connected to a computer directly by Ethernet - or by a more exotic cable; one webpage about my modem goes so far as to suggest that I need to fiddle with physical pins).
So at this stage I am ready to follow the advice of the page (the page) where it says that, in the DD-WRT interface, I should do:
Quote:
Assumes LAN subnet 192.168.2.nnn and modem at 192.168.1.1 (change as appropriate):
ifconfig `nvram get wan_ifname`:0 192.168.1.2 netmask 255.255.255.0
But I do not know how to change as appropriate. For, just how do (1) the LAN subnet IP and (2) the modem IP relate to the numbers in the command? And simply pointing a browser, or SSH, at the modem IP (/any of the plausible modem IPs) failed.
EDIT: Somehow through all that messing around I stopped being able to log into the router GUI. I rebooted it via SSH and it's fine now. Also, in my travels, I discovered . . this .. _________________ My router: Asus RT-AC66U

I think I'm going to get a new modem (not router) and not from my ISP. (My ISP now supplies only a modem integrated with a router. That all-in-one unit is called 'Hub One'.).
Can anyone give me any general tips on how I would get such a modem to work with my DD-WRT router, and perhaps one what a good, home modem - for broadband (fibre-to-the-cabinet) would be? Thanks. _________________ My router: Asus RT-AC66U

not bad idea to tell us what country you are and ISP you use and what interface you have (DSL, RJ45, DOCSIS...
for example for UK and connections around 100-1500MBit i can recommend EchoLife HG612 (it works on BT or Plusnet)...
Don´t know about this one. Not many ISP use two physical fiber lines, TX and RX on separated "cable" ). Usually what I see is just one fiber "cable" for TX and RX. At least for private consumer. I saw once a business consumer with that configuration, 2 fiber "cables". But we are talking about terabit connection
Your example, should be a must for connecting 2 separated building/home for private use.
