@Jesephny,
The more topics you start and more question you ask, the more I wonder where do you get your "problems" from?
They are so awkward that I suppose that you create some tests for ... I do not know who.
Are you a homebrew IT guy and you tinker a lot or do you offer IT services and want to give you free services to let you be payed?
Some quotes of your problems.
I have 8 sites – call them A, B, C, D, E, F, G, H
All connected via Wireguard, and all have been working perfectly for many months.
I have a site running a Ubiquiti UDMPro, USW 16 port switch, 8 APs, several servers, a hEX (just for Wireguard and DHCP), a Cube-Cube-wAP, and a few other things.
So I’ve got an RB5009 chugging along (i.e., doing just fine) and running 7.16.1
Not satisfied to leave working things alone, I set about to upgrade to 7.17.2 (being conservative and not going near 18 or 19beta).
I’m seriously considering changing the UDM and USW to MT devices. I would keep the Unifi APs.
I’ve got a hEX (RB750Gr3) running 7.17.2 (routerboard and firmware) with ether1 (WAN) connected to a Spectrum Cable Internet modem and I believe the connection has problems.
I’ve had Spectrum’s tech out twice and they tested and swear that there is no problem on their side.
I have an RB5009 connected at 1Gbps using twisted pair on ether1 to Verizon FIOS.
I have a need to create a 1.3km connection, but my basic understanding of RF says that it will not work.
Does anyone know which devices work well with Verizon cellular data service in NY, USA?
I need Internet connectivity at a location and the only established provider is Spectrum Cable with a base cost of $50/month (plus taxes and fees, over $60/month).
Don't you think these do not sound as a home lab problems?
