I'm looking for a possibility to make my desktop WiFi compatible. Currently I'm using a USB-stick that connects to the router, but it's not the best solution as it sometimes loses connection and isn't made for continuous service.

Thus I started looking and found that PCI cards have better performance. My current pricing wish would be around 30€, but it wouldn't be a big deal if it cost more. My Mainboard is an ASRock Z77 pro4 and the only PCI slot I'm using is for my graphics card (This graphics card blocks the neighboring PCI slot).

I want to sometimes play online with the card, so connection quality should be as good as possible and several hours of operation should be no problem. I'm using Win7 and (arch)Linux.

Note that I'm not up to date on the PCI standard, so I use PCI to refer to PCI-e, 2.0 and 3.0 interchangeably.


I recommend the TP-LINK TL-WDN4800


This card uses PCI-E. According to your board specs, you have a slot for this. You do mention your card blocks the neighboring slot - you will need to check that though, as the PCI-E slot is next to one of the slots you'd put a video card in.

Other features include:

  • Dual band (it operates on both the 2.4GHz and 5GHz bands). You should be able to connect to almost any wireless network.
  • Compatible with wireless networks that use the B/G/N(2.4Ghz) and A/N(5GHz) protocols

The biggest down side is that it is slightly above your budget at $40 (which Google tells me is currently 35.50€).

As a side note, if you are willing to spend more, there is a new version of this card available too. It is the TP-LINK Archer T6E AC1300. The major difference is that this also supports the newer AC protocol.

  • Thank you for your recommendation, I have a bit of flexibility for the price so this is no problem. I just checked, it's actually an ASRock Z77 Pro4. I have one slot next to the CPU free that says PCI-E 3.0 so that should fit right? (Wikipedia says pci-e is backwards compatible) Is the ac standard worth it in your opinion? As I see it the internet connection will be the bottleneck by far, and I won't transfer files between computers in the local WiFi network. (and if I ever do I can wait a bit on the transfer) Edit: and the card actually costs 31€ at my online shop, thank you very much – Gaze Aug 17 '16 at 16:47
  • Unless your router and other devices on the network use the AC protocol, I wouldn't worry about supporting it right now. If the router doesn't support it, there is no need at all to worry about it. – Andy Aug 17 '16 at 16:53
