WAN will only function at 100BaseT
-
Hey everyone,
So first off, I am a newbie to all of this and am just starting to "dip my toes in the water" so to speak with anything above consumer grade. I have seen on YouTube the wonderful magic of pfSense and wanted to give it a try if for no other reason than internet privacy tools and such.
The problem that I am having is that my server will only negotiate a 100BaseT connection to my modem no matter what port I choose. LAN connections on all of those ports happily goes for 1000BaseT. To further muddy the issue, my modem happily negotiates 1000BaseT with my consumer router..... so I'm at the point where I have no idea what my issue is.
I am running an older Spectrum rented Arris tm822 modem, an Intel S5000PAL server with dual E5410s and 16 gigs of RAM, and just tried adding an Intel PRO/1000 PT Quad Port LP Server Adapter to see if the motherboard's built in Intel PRO/1000s were just crap or something. Yeah it's older hardware and not energy efficient, but the server was a cheap way to see if I would even want to bother with pfSense long term.
So, once again, the modem will only connect at a 100BaseT full-duplex connection to my server and only delivers about 68Mbps download when I am normally getting 140-160Mbps download if I connect my modem to my Netgear Orbi router. I would think that I should be getting at least 90Mbps accounting for overhead and the universe hating me over a megabit connection, so clearly there are shenanigans happening. Beyond assigning ports and disabling Hardware checksum offload as an attempt to fix the speed issue since I keep seeing that suggested to others, this is a totally stock install of pfSense 2.4.5. What can I do to try and fix this?
