SG-3100 new install LAN link fail
Today I attempted the install of my new SG-3100, replacing a Netgear FVS336Gv3 firewall / router for my home. Netgear is no longer supporting the FVS336G, and I am eager to explore pfSense.
I cabled my WAN and two leftmost LAN ports 1 and 2, to rooms 1 and 2. No problem with the install or WAN connection or network access through LAN2 to room 2. But I get no LED link lights from LAN1 to room 1, and no network access.
The ethernet cable for LAN1 travels through the walls of my small condo over builder-installed wiring, including a splice at an old telephone jack and on into an equipment closet. When I switched back to the old Netgear FW the link is live again with network access.
Switching LAN ports, cabling LAN 1 to room 2 gives me LED link lights and network access, but cabling LAN2 to room 1 again fails.
Could the LAN ports of the SG-3100 be under-powered compared to the Netgear FW, resulting in the loss of signal for this particular cable run? How might I solve this? I deeply appreciate any ideas!

There is no such thing as "underpowered" for network connections (if you don't think PoE, of course).
Either the cable pairs are crossed over or only 2 conductor pairs are used in the cable (instead of all 4). Might be even both. This may result in the SG-3100 not recognizing the link.
If you have a switch handy then connect room1 to it and look at the LEDs if it links with 100MBit or 1GBit.
Thank you so much for your attention and reply!
I know you are correct about power, but I'm baffled here, since the NetGear hardware firewall/router makes the connection while the Netgate SG-3100 does not. I imagine successful or failure link behavior between the two should be the same!
Yesterday I did connect the SG-3100 LAN1-Room 1 to a Netgear switch I have and did not see any LED's light. But I will try it again this weekend. My wife and daughter are on the network pretty-much 24x7 so I have to work around them or they get crabby!!
Any ideas to test continuity of the conductors from each end of the cable run?
Yeah use a cable tester.
Anything from something you might get at a home center to an LRAT-2000 or better.
Something like this will do what you need.

Probably even something like this will tell you about the wires:
even though I don't like these kind of "testers" too much. But for the price point and because you probably won't use it much after it's ok.
Thank you jahonix and Derelict! I'll purchase and use a cable tester as my next step. I'll reply with my results, likely next week.
