OnBoard Intel or External NIC

Thx for help**

Mother Board Main Specifications according to hardwaresecrets website

On-board LAN: two Gigabit Ethernet ports, one controlled by an Intel I219V chip, and one controlled by an Intel I211AT chip

for some reason gigabyte do not provide more detailed information about lan chips

i assume it's an good solution ? with more newer chips on board.

So the question is what to choose
On-board VS External NIC or there is no difference.

The question should be more likes consumer or server grade NICs.

i found on ebay some used cards from US
about 30$
INTEL PRO/1000 PT DUAL PORT PCIE SERVER NETWORK ADAPTER D50868‑003 EXPI9402PTBLK

Some of the PT card are having issues, problems and/or running not fine under pfSense.

and find new one from china about 20$-50$ example:
INTEL EXPI9402PT PRO/1000 Dual Port Server Adapter PCI-E Network Card 82571 OEM

This ones can also be fine running but without a guarantee of this!

but on Chinese ones they put this note
Note: This card it is 3rd party cards with Intel chip set.

Perhaps they payed a license fee to Intel
Perhaps this are original chips and they produce in license
Perhaps this is a fake and worse the money you want to pay, you only know it really late!

So its worst to get used one (looks like original) or try a new(Chinese) card with intel chip set.

An original is an original and will it even be it and refurbished is also an original.

And a fake will be even a fake, it can be running well, but as said before without a guarantee.

A third party NIC must not be bad and can also using original chips or is produced in license
but to be sure that your card will be benefit from the drivers and the given by them features too.
Here is an example for 3rd party NICs from HotLava

Not exactly
you can get server grade board with onboard lan
(in this case its only matter how much you wanna spend )

what i ask if external lan adapter have benefits over onboard lan
and opinion of people who work with different hardware on pfsense platform.

fully agree
i'll never know until try

Unfortunately on this forum i can give to every one thanks for they post (only one per topic).
only find out when i use first time "Thanks you" button

This one mostly then came only without a real DSP and/or FPGA/ASIC, only with a LAN chip and are cheaper.

and opinion of people who work with different hardware on pfsense platform.

On consumer or desktop NICs you will only have a small chip that is handling the parity of the TCP/IP packets
On server grade NICs you will have a real DSP (digital signal processor) that is mostly much more offloading
from the entire TCP/IP workload and packet flow and this is then saving much CPU horse power. And the greater
ones are sorted with a real ASIC/FPGA that can fully offload network tasks such as VLAN, NAT, ect…...

And so the price will differ from a small amount to a huge amount for that cards mostly.

Under each name of a forum member you will be able to click on "applaud" or "smite" to give
them plus points or minus points how often you want.

Now i get more clear image about external and onboard nic, and now i understand why you said that :"The question should be more likes consumer or server grade NICs".
thx you for more detailed explanation about differences.

i will considering to get an external nic(on more big networks),
and for home i assume onboard is more than enough?

I am running that exact board with an i5 and 16gb of ram. I'm sure you will run 2.3 but one of the Nics isn't supported in 2.2.6 without a lot of fiddling. I run both on board nics and a dual PCIe Intel nic and cannot tell the difference.

one thing about that board is it takes forever to boot off the USB, probably 10 minutes or more. be patient, once up and running, it is very solid and runs great.

There might be not difference pending on the traffic that runs through the NIC.

Good to know
Yep its will run 2.3.1(or latest one)
i hope its will work smooth out the box without problems

For the same ethernet chipset, onboard might have different performance than the add-on one.
There is another thread in this board (the J1900 w/4 LAN port) which shows something we might easily missed during selection.

The PCI-e bandwidth sharing can be a problem for LAN chip, some consumer grade device manufacturer might be putting quite a number of devices together on the same lane, somehow for certain low end processors they might be able to provide very limited PCI-e lanes which is not capable to have onboard LAN running at full speed all the time. But for a LAN card occuping separate PCI-e slot, most of the time this is using a dedicated PCI-e lane and so the performance can be guaranteed. Of course you don't need to worry about i3/i5/i7/xeon platform as these CPUs provide plenty of lanes for us while some low end ATOM processors might probably have this issue.
