I recently updated the firmware on my Mac Pro 2010 5,1 to version 144.0.0.0.0. Now, my ethernet card (Intel 82574L) does not work. My computer seemed much faster when it was hard-wired directly to my router. Using the wireless network, it doesn't seem nearly as fast. Is there a compatible Ethernet Card that I can purchase? On Intel's web page, there doesn't seem to be any new drivers for Macs.
Mac Pro, OS X 10.11
Mac Pro 5,1 has TWO Gigabit Ethernet ports built in. They are low on the chassis at the back.
You can use either. Drivers are built into MacOS, and they are well supported on into later MacOS as well.
Updating the firmware to 144.0.0.0.0 DOES NOT disable the built-in Ethernet, (but changes to network settings might knock them out of kilter).

Wi-Fi seems slow on that MacPro because it IS slow.
The standard wifi card connects using 802.11n protocol only, so its top speed is 300 M bits/sec when connected to TWO of the provided Three antennas inside the box.
Some users have substituted a wifi card that is more capable from a later Mac, and that setup supports 802.11ac. it allows connection of the three Wi-Fi antennas inside the chassis. Speeds up to 600 M bits/sec using a 40 MHz channel, and up to 1300 if your Router can support a 80 MHz channel.
Hi Grant... thank you for your response! I swapped the CAT 5 cable to the 2nd ethernet port and it worked!! Perhaps it came out of its funk... I don't know. For now, I'll leave well enough alone! Again, thanks so much!!
It is very common for software updates (such as the one required to reach that version of firmware) to make changes to parameters that can cause malfunctions in older versions.
Re-specifying the parameters (or just using the "clean' second port) can allow you to walk away from all the settings and set new ones that work in the current version.
