Summary: Had issues in getting this to run at gigabit speeds so after swapping out several network cables it finally went into gigabit mode. I used with the TP-link gigabit switch TL-SG108. I did have to go to the site to find the latest drivers. the ones on the mini CD werent the latest.
Summary: I bought this because the ethernet port on my motherboard (Asus Z87-A) keeps dying. The first board failed after only 2 weeks so I was able to exchange it with Amazon. The second board was fine for 3 months until the port stopped working. Rather than send the board in for warranty repairs with Asus, I opted to just buy this card. The card works great out-of-the-box with box Ubuntu 13.10 and Windows 7.
Summary: Couldn't get it working in an HP xw4400X workstation. This was the PCIe version. Kept getting errors from the driver at startup. Then the little yellow exclamation point over the device in Device Manager. Did a driver update. Nope. Updated the BIOS in the computer. Nope. Freed up interrupt lines by disabling other things. Nope. Installed the driver in Safe Mode. Nope. Just couldn't get it working. I went on the TP-LINK support site and was underwhelmed as well.
Summary: I've got it to use with TP-Link's own TL-PA511 power Ethernet bridge. Cheap Atheros network adapter was giving me troubles working with it (zero problems with Broadcom and Intel cards), so I've got this TP-Link branded card as an upgrade. Nope, same issues - network goes down every minute, speed is the level of dial-up. Worked fine while connected to the router, but since it doesn't work with their own equipment 2 stars only "i don't like it".
