So I've had three weird scenarios to date:
forums.anandtech.com
TLDR: Packet loss from my main PC showing itself in slow page loads and poor download performance
NB: The questionable 8-way in that thread has been taken out of duty completely a few months ago.

TLDR: internal networking to my server wouldn't work until about a minute or two after booting. My server could be accessed externally to my network just fine the whole time.
A good while after that second thread I had some more problems and out of desperation I power-cycled all of the mains networking adapters and all the issues from the second thread disappeared entirely and haven't returned since, which was probably two months ago. Two months of working networking! Luxury.
Today's issue:
Everything has been working fine until I left the house this afternoon and visited a customer. After installing their new router, I tested their connection by loading my website. Nothing. Other websites: fine. Same result on my phone via 4G.
I got home and internally everything was fine, I couldn't see a single thing wrong. I tried power cycling my router anyway, the problem remained. I was checking my domains' registrations in case there was some common factor like a downed DNS server (my home router has manual DNS entries so my own resources work internally via name), nothing wrong there and some domains are registered independently of others. I almost rang my ISP but thought I'd better rack my brains for another reason, then I remoted in to my server and sure enough it hadn't had any new e-mails arrive after a couple of hours before. I then went to google for something off my own server and it said Google couldn't be contacted, though it could on my machine. Hrm. Ping my own router from my server, nothing. Ping my workstation from my server, works fine. WTF? Disable the server's firewall, still nothing. Reboot the server, still nothing. Power cycle all the mains networking adapters: Voila, everything back up and running.
So, what to do.
One course of action I suppose would be to factory reset all the adapters and see how things go. I have spares and I can't believe they're all faulty, but I've tried the whole 'power cycle one at a time' lark and it made no difference so I'm wondering just how I can go about narrowing the problem down to a particular adapter (or more than one). It seems crazy to just chuck them all out, especially considering that I could end up with egg on my face whereby the new adapters end up having the same issue.
PowerLine (mains networking) adapter issues
I've been using powerline adapters to supply networking throughout my house for a couple of years now, and until very recently it's worked pretty much perfectly: Maybe once a year I'd need to power-cycle one for 30 seconds, but pretty plain sailing and pretty much perfect throughput onto the...

Lubuntu 18.04 RTS x64 networking problem
I've been using it for a year and a half now and this weird little problem just came out of the woodwork and I have no idea what might have caused it. I have my own server (web/mail/other stuff) on my LAN. I have TB set up to check mail with it and I also pick up my calendars off it. Recently...
