re: House wired with RJ45 and POTS eGrand "switch" can't get Ethernet

The switch has to be configured. IMO, you'd be best served by getting a plain old dumb Ethernet switch and your problems should be solved.

thats great and all but i already tried that. i mentioned above i have a box of dumb 6-port switches and tested those with the same result.

but i'm all for learning what i'm missing by running an industrial-grade rack switch vs using a $10 monoprice dumb switch. certainly having 20 ports all in one place makes things look cleaner and i'm less likely to run out of ports.

Have you hooked up a computer directly to the ethernet out of the router?

yep. before i set up my rack i was using the built-in ports on the back of it for a few days when i first moved in. the plex server was one of those devices plugged into it.

What is the likely issue here?

Hire someone who knows what they are doing

Cad, I thought you were more technically inclined than this.

at least a 12 year old switch made to be in a data center.

and your point?

It's probably creating more noise/heat/power usage than necessary for your situation.

That being said, I myself use a 48-port + 4x10G HP/Aruba managed POE switch in my rack, but I have a home server with over 50TB of network storage and actually use the 10G functionality and swapped the fans out for some silent Noctuas. Powers my IP cams too.

Let me make sure I'm understanding.

You have cat5e in the house but it doesnt work when plugged into your switch. You've plugged in a laptop or some such device directly to your switch and it works, but when you go to one of the jacks in the room, it doesnt work. Right?

Its been clarified to just ignore the legrand stuff and rip it out.

You've showed us the termination in the closet and it looks right for Ethernet, but we need to see the termination at the jack. They may only have 2 pairs punched down on that end for the phones.

I've got a great one. 10gbit actually.

Nah, that's the uplinks, and you need to buy the modules.

OH MY SWEET JESUS

Does the switch have a DHCP server? Is it on or off?

---

i've tried a cardboard box full of various switches to no avail in addition to the rack HP switch.

Is the ATT DHCP server on/off?

---

its on but seems to have some issues 'seeing' remote switches connected instead of straight connection to a device.

How does the switch get its IP address?

dynamically

Is the router different from your old house?

---

oh everything is different. i had comcast at the old house and a EERO mesh system which was pretty much bulletproof. i sold the EERO to the guy who bought my house because i had it optimized for the house (4500sf on a single level meant that a 3 node mesh was a REQUIREMENT to get decent coverage)

new house i have 1GB att fiber and whatever shitty router they shipped to me. i hate it but researching and setting up a mesh system is not something i want to undertake right now.

UPDATE - so i gave up trying to connect a switch upstairs. tried 3 different brand switches; none would work. tried direct connection to the TV upstairs..no dice.

FINALLY decided to plug it directly to my sonos playbar and bada bing! 10-15 minutes later (so fast! so fast!) my sonos network came online and the light at each end of the cable is on. luckily the playbar has 2 ports so i added a second cable OUT to the switch..holy bananas that seemed to work. Plugged the tv in to the SAME DAMN SWITCH i've been trying to get working for days...now the TV is up too.

something fricky going on. this feels really 'fragile' but it seems Mr. AT&T router LIKES the sonos ethernet port so i'm using that for the moment as my upstairs 'hub' and running cables to all my other shite which includes:

- pixelcade arcade marquee display
- raspberry pi 4
- legends pinball machine
- work laptop
- daughter's TV

thanks all. i have no explanation and i'm guessing this might crap out at any time so i may be forced to get my own router & mesh just to get around the ethernet allocation issues with this shitty router.
