Had a Sony Ericsson W580i back in high school. It was a slide phone. 15 hours talk, 570 hours standby. That’s nearly 24 days of standby. I charged it maybe every two weeks. It was tiny(So not great in your hands I guess). We don’t need unwieldy huge phones for good battery life. Still had a basic browser and was part of the ‘Sony Walkman’ lineup so was a decent enough music player. Modern phones are just power hungry cause they have about ~12x the power of my first desktop computer.
Crap photo but shows many angles.
I made the hop to 10g and it can be expensive depending on how many ports and how you do it. I found it cheaper to run fiber through my house rather than do cat cables again. I pull my own cable though. The SFP+ transceivers are significantly cheaper for fiber than RJ45 ethernet and the cables are about the same. I’d terminate my own cat cables but I just bought prefab fiber. Used the foot markings on the cat cable(from a 1000ft spool) I originally ran to figure out the length.
Here’s the wall plate in my office which has multiple 10g machines(SFP+ networks cards). I ran fiber out to the living room switch as an uplink as well.
For the short 10g runs between servers and switches in the basement I used DAC cables.
I have no idea what the specs are for your Wifi7 router from the ISP are but you’ll likely need a 10g switch for additional devices hooking up to it.
