i didn’t downvote but 17v on a 12v battery maybe seems a bit high. I’m more used to about 7-14% over (maybe up to 14v on a 12v batt) when charged/floating but i don’t use solar anywhere currently, and i usually work on 48v systems. i normally expect to see about 54v on a fully charged battery string (13.5v per battery x4) with the rectifiers running.

i also second the opinion of running an automotive PSU for this situation.

edit: i looked it up since i was curious, some “12v” solar panels can output between 16-20v, but it’s recommended that you would use a charge controller, especially if you have lead-acid batteries

i buy my domains from namecheap but i use cloudflare for name servers (free tier, dns only for everything) and have ddclient (or whatever the newest version is called now) which runs on my router. my current settings only update cloudflare when the interface changes, and then update time after the change is about 15 minutes for propagation. i work in the network department of my isp so my address doesn’t change often, but the isp side of my setup is identical to any other subscriber. i use opnsense, but also manage a very small pfsense box that this works on as well. i update ipv4 dynamically, but not ipv6 yet, but i will.

hardwire for testing? then when settled do the full install. maybe use a different laptop.

i looked at the cross-post, do you have the spec sheets for transceivers? do you have any sort of filter / mux panel.

short between pairs probably. tdr (time domain reflectometer) cable tester should help locate fault. might be pinched somewhere or something else

there are “casts” you can get to repair buried cable. usually used in copper telephone plant, i wouldn’t trust it to certify to a gig but you could use it for a backup link or if you play with pots at some point. or “temporary repair”

yeah that’s garbage, we just started rolling 2.5/500 in certain xgs-pon areas. i think minimum now (for fiber, we still have vdsl/adsl) is 500/50. i don’t sell any of it just work on the technical side.

Some service-provider level technology is not symmetrical at the access layer. An ISP serving exclusively fiber may have values like below:

GPON (GIGAbit passive optical network): 1.24416 Gigabits/s up, 2.48832 Gigabits/s down

XG-PON (10 gigabit passive optical network): 10G/2.5G

xgS-pon (10g Symmetrical optical network): 10g/10g

Note that on all of these technologies, you are also sharing bandwidth with neighbors on your PON. Sometimes up to 64 subs on one gpon. I think 128 on xgs-pon Until more providers make fiber available, as well as are willing to fork more up for the latest equipment, and reduce the over subscriptions of pons, symmetrical services for everyone just won’t happen.

Will this ever happen at mega providers / baby-bells? Probably never unless a regional or startup pops up, and then they will only attempt compete in that market.

i would expect your lengthy research would have included “router model default password”, “reset password router model” and “port forward on router model”
