Review: Exactly what I needed - I purchased this NIC to bypass my motherboard’s integrated Realtek controller that was forcing my computer to be limited to 100mb/s network speeds. This NIC was very easy to install, and I was immediately able to see an improvement in speed as it auto negotiated true gigabit speeds with my switch. My ping dropped from 7 to 1ms, and streaming videos no longer freeze temporarily. Delivery was fast, and the contents were well protected. A great value for the money for the performance of this NIC.
Review: Easy setup and fast. - My onboard network quit working. Used a x4 slot and it works perfect. Now I have 2 ports which my Synology uses. Easy setup and fast.

My onboard network quit working. Used a x4 slot and it works perfect. Now I have 2 ports which my Synology uses. Easy setup and fast.

### ⭐⭐⭐⭐ Easy to install and load drivers.
*by A***A on July 1, 2023*

DIED after two weeks. During its brief life it worked great. Guess I'll be spending a little extra money on something better. We had a lightning storm. I checked my computer devices to see if anything was damaged. Everything runs through an APC ups circuit protector. Everything is fine, however now the Network Adapter is working. Two weeks so far. I'll let you know if that changes. Spooky.
