The market for miniPCIe wifi cards is surely much *much* larger than for full-sized PCIe ones. Every new laptop needs a wifi card, and that'll be miniPCIe. If someone is adding wifi to their desktop, then they'll probably use a USB NIC. When the manufacturer is already making lots of miniPCIe cards, what's the point of making full-sized PCIe cards, which will hardly sell? Especially when they're the same bus with a different form-factor, and a convertor card like you've bought can be bought or manufactured cheaply. Stroller.

Re: [gentoo-user] {OT} 802.11n PCI-E 300Mbps with AP mode?
Thank you. It looks like you are using it in AP mode but in 802.11g mode. Is that the case? I'm also curious if it can operate in both the 2.4 and 5Ghz bands? Sorry - dont know how to tell if can use 2.4 and 5. It supports 2.4GHz only.

I think you need 2 cards in your router (one as host and one as client to the wireless WAN bridge), unless you use WDS. WDS allows your access points to become repeaters while still functioning as access points, so you can have multiple APs and only one of them needs to be connected to the wired network (as long as each AP is within range of at least one other AP). The cost of WDS this is that your available bandwidth is basically halved (and if you have to support 802.11b, it gets even slower). Depending on your expected usage, that might or might not be a big deal.

Should I need only one wireless card in my router to connect to both the clients and a wireless bridge which is connected to the WAN? I think you need 2 cards in your router (one as host and one as client to the wireless WAN bridge), unless you use WDS. Got it, thanks Paul. That's good news because it means I can use any 802.11n PCIe 300Mbps card with Linux drivers instead of worrying about AP mode. I'll just use a 802.11g card in AP mode until there is better support for 802.11n. The router uses most of the bandwidth from the WAN. - Grant WDS allows your access points to become repeaters while still functioning as access points, so you can have multiple APs and only one of them needs to be connected to the wired network (as long as each AP is within range of at least one other AP).

Hi Grant, I bought the TPLink WN951N (atheros AR5008, ath9k) card after it being recommended by a gentoo-user list member. I concur with the recommendation. Its cheap and seems to work well in linux. I have, at times, had scp report 3.5M/s, but its quite variable. There are a bunch of APs in my area though. Here's some details - I dont know if the AP configuration is optimal - I didnt find the documentation very clear. Here's what's reported as the Wiphy phy0 Band 1: HT capabilities: 0x104e * 20/40 MHz operation * SM PS disabled * 40 MHz short GI * max A-MSDU len 3839 * DSSS/CCK 40 MHz HT A-MPDU factor: 0x0003 (65535 bytes) HT A-MPDU density: 0x0006 (8 usec) And i've configured my hostapd.conf; hw_mode=g wme_enabled=1 ieee80211n=1 ht_capab=[SHORT-GI-40][DSSS_CCK-40] HTH

Its certainly counter-intuitive, but that's what I found when I searched N configuration. I have had better than 54M bit rates reported, so despite the G its working as N. I think
