Can you provide the output from #iw list ?

By: Tom

As far as I know both are working but I don’t have any 11n devices so I haven’t tested that side of things yet.

Thomas,

Can you tell me if you’re able get your WPEA-110N operating on bother 802.11n and 802.11g simultaneously using hostapd?

I’m building a similar type setup and my goal is to be able to provide 5Ghz 802.11n as well as 2.4ghz 802.11b/g (Similar to how an Apple Airport Extreme/Time Capsule works).

Sorry I think I’ve missed your last post :)

Could you please write more about the wifi card. Name or chipset would be helpful. I’m trying to do the same thing you did and I have to choose a wifi card.

It was a SparkLAN WPEA-110N which is based on the Atheros AR9280 chipset. I got it (in the UK) from OxfordTEC.

Can you tell me what card You inserted in Your Project? I’m looking for Mini-PCIe Wifi 802.11n card with Master mode to work as Access Point and can’t find anything :/ Thx in advance

Well 802.11n won’t go to a gigabit anyway, so if you’re using it for a wireless card then even with 802.11n the maximum theoretical bitrate is 600Mbit/s and practically it will be less than that. Which means even a 32 bit, 33MHz PCI card should be able to handle it.

Great, thank you. In that case the PCI card should not choke things much, if at all. It seems a Gigabit is about 125 MBytes and the PCI card at 66Mhz should be able to handle this. I do not need the bandwidth currently but one should consider the future (my oldest son is 5 and will soon be demanding resources!).

Hopefully, I can order this package and have it running shortly.
