UPDATED - Wrong details - TP-LINK TL-WN781ND - Atheros AR9285 chipset



  • Hi all,

    Just got a TP-LINK TL-WN751ND TP-LINK TL-WN781ND with Atheros AR9227 Atheros AR9285  chipset. from my understanding this chipset is meant to be supported but my unit seams fail to see the card at all. Can anyone confirm this card works or what I need to do to make it work?


  • Rebel Alliance Developer Netgate

    That might work on 2.1, but not 2.0.x.

    What evidence leads you to this suspicion? You expected to see … but saw ... (For example, I expected to see ath0 on the Interfaces -> (assign) page but saw only the wired interfaces.)

    Well ifconfig shows no ath0 interface at all, pciconf shows the card like the following

    none1@pci0:1:0:0:      class=0x028000 card=0x3118168c chip=0x0032168c rev=0x01 hdr=0x00
    class      = network

    But no other information at all, dmesg shows it sees a pci device but no driver for it.

    Tried both 2.0.1 and 2.1 Daily snapshot in both 32 and 64 bit versions both the same result.  do i need to activate the ath4 drivers manually or something?



  • ok after some digging it looks like i may have a V2 card with a new chipset AR9485 anyone know if this is supported?



  • A quick scan of the ath driver source code suggests this isn't supported even in FreeBSD 9.1.

    Thought that may be the case, do you know of a recommended card that's PCI-E and easy to find in the UK? not to fussed about N class. just want to install it all in a single 1u supermicro chassis I have.  multiple SSIDs are a bonus.

    Little annoyed TP-Link changed the chipset but dont list the hardware revision on the cards box.

    Tell them and explain why you are annoyed.

    @nfz300zx:

    I can't recommend one from personal experience.

    The AR9285 chipset appears to be recognised by the ath driver in FreeBSD 8.1 (hence pfSense 2.0.x) and FreeBSD 8.3 (hence pfSense 2.1 snapshots).

    A quick scan on eBay turned up a number of sellers of mini-PCI-E cards with AR9285 chipset. I have also seen a number of eBay sellers of adapters that plug into "full" PCI-E slots and take a mini PCI-E card.

    The Ralink RT3070 chipset USB will operate in Access Point mode but the driver (hardware?) doesn't support multiple SSIDs. A number of readers of the pfSense forums have had success with adapters using this chipset. The chipset is apparently "fairly old" and adapters using it are no longer readily available in retail outlets near me but there seems to be good supplies from eBay sellers.

    Hey Wallabybob,

    Thanks for your help, I managed to find a laptop mini-pcie card from a work buddy who got it for his laptop but decided not to use it and an adaptor from ebay. that seams to be picked up fine.  Also just got a d-link 556 and thats picked up as well so i just need to workout how to setup the wireless now….... think i set it up but don't see the SSID

    As for everything else, pfsense rocks.  have my VPN working from home to the box at the datacenter where my VMs are. have my IPv6 HE tunnel running on my second unit (2.1 Snapshot) and its working absolutely perfectly bar a couple of issues but thats probably down to it being the 2.1 snapshot (RRDtool not working).
