What is a PCIe 802.11/b/g/n compatible card? (re: half-length cards)



  • I'm running pfSense on a
    Super Micro X7SPA-HF motherboard inside a Super Micro CSE-502L-200B chassis and I need a PCI Express wireless card.

    According to the chassis (1U) manual, I need a "full-height, half-length" card and a PCI Express riser card.

    Can anybody give me any recommendations?

    I'd like something that supports 802.11/b/g/n and dual-band (so I can use 802.11g and 802.11n at the same time).

    Thanks for any suggestions!

    EDIT:  Hmmm… is it true that 802.11n isn't supported at all by pfSense?



  • As best I have been able to tell, there are limited options in PCIe wireless NICs and they are comparatively expensive.

    I'm using a "N capable" USB NIC. There are at least a couple of cheap "N capable" USB wireless NICs.

    EDIT:  Hmmm… is it true that 802.11n isn't supported at all by pfSense?

    I believe the current state of affairs of pfSense 2.0 is that some "n capable" cards are supported but the "n specific" features (including speeds above 54Mbps) are not yet supported. I have a "n capable" interface working on pfSense 2.0 but don't have any other "n capable" equipment to try "N" speeds. My "g" netbook talks fine with this "n capable" interface.



  • Thanks for the information.

    Does that USB adapter work in pfSense?

    Right now I'm looking at the D-Link DWA-556 which is PCI Express and uses the Atheros 5008 chip which supposedly works.  I don't really need N speeds so it's not a huge problem… I just want to get rid of my separate access point really.



  • The TP-Link TL-WN321G is a "G" device, supports AP mode and is supported in pfSense 1.2.3 and 2.0.

    The Tenda W311U is a 150  MHz "N" device supported by the run driver in pfSense2.0 and supports AP mode. I have both of these devices and they give satisfactory performance around my two floor house. I have not run any sustained downloads or uploads over either device.

    The Tenda W322U is allegedly a 300MHz version of the W311U so should also be supported by the run driver in pfSense 2.0 but I have no experience with it.



  • Since I've got the same motherboard & case, I thought I'd share my plan to do the same thing:

    Potential Solution A:

    Potential Solution B:

    Parts have not arrived yet so I cannot report on how well either plan works at the moment.

    this is a great idea bob, im planning for this stuff - tenda w311u.
    if ever i have this stuff i will extend the cabling for this, doing some DIY…^^
    instead of using router which gives me headache...lol
