## Questions & Answers

**Q: Will this work with Truenas Scale? Linux**
A: It should, it works with PFSense and OPNSense. Both of those are very picky when it come to brands. This is a intel nic.

**Q: What is the upload speed of this card ?**
A: It really depends on what your internet service and router can do. This card is capable of doing 2.5 gig up and downstream if you're other equipment supports it.

**Q: does it run on 
synology**
A: yes

**Q: Will it be recognized in PFSense?**
A: It is an Intel based adapter, so it should work just fine.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nic
*by C***S on 27 January 2025*

Plugged in and worked what more can be said

### ⭐⭐⭐⭐⭐ Item works well but changing from full to low profile bracket has odd screw head
*by P***D on 13 July 2024*

This item works well in the SFF computer it is fitted to. I had to change over from the full height bracket to the low profile bracket (supplied in the box). The 2 screws holding on the bracket are an unusual head and do not fit a Philips or torx, etc. A small “screwdriver” is supplied but it has a very narrow handle and if a screw was stuck/tight, you would have a problem changing the bracket.

### ⭐⭐⭐⭐ While it works, it is based on I225 - which is known to have issues
*by A***N on 17 October 2023*

As mentioned, this is an I225 controller, which are known to have issues. I wanted this item to get the maximum download speeds from my 2gb internet connection, which it delivered. However I would not use this for online gaming as you can get connectivity problems (do a Google search for I225 problems).
