Hey guys!
Got myself an Acer Aspire One 721 yesterday, botted it up, laughed hard at the Win7 Home Premium that was preinstalled and dumped it in favour of a Win7 Enterprise/Arch dualboot.
So far everything works fine, except for the WiFi.
First I tried using b43, to no avail.
Then I installed the BCM4XXX drivers from aur, which brought my WiFi to show up in if/iwconfig. However, I can't get a connection to any AP, neither by iwconfig/wpa_supplicant nor by NetworkManager.
I narrowed my problems down to the following:
- This does not seem to be NetworkManager/wpa_sup/whatever-related
- rfkill list all shows me the following:
0: acer-wireless
Soft: yes
Hard: no
- When I do a rfkill unblock 0 / wifi / wlan / all, tail -f /var/log/messages.log tells me the following:
1. Card gets activated (state: 2 -> 3)
2. configs start kicking in (wpa_sup mainly)
3. Card is fully there
4. Card gets downed instantly (state: 3 -> 2) with (reason: 0)
So to me it seems that the rfkill does not manage to activate the card.
And now the question:
How do I tell my system that, yes, this card needs to be activated, and stay that way until I say otherwise?

Hi,
I also have an Acer aspire one 721. This is probably not the answer you're looking for, but I'm using the broadcom-wl package (it's in aur) and everything works fine. I haven't tested it extensively but for my uses it has worked well. You can also use the new brcm80211 package also in aur. The brocm80211 package is still in development and has problems with multicore systems, which shouldn't be a problem. My network card is
Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)
https://wiki.archlinux.org/index.php/Broadcom_BCM43XX
Hope this helps. Does scrolling on the touchpad work for you? Or multigestures?

I'm using broadcom-wl from AUR, too.
I'm starting to suspect that it's a problem with me dualbooting, that somehow my Win7 sets some kind of "sticky-keep-it-off" bit on the adapter.
Do you dualboot or is it pure arch on your book?
WHich 721 do you have? The 1.7GHz version w/ 250GB HDD or the 1.8GHz w/ 500GB HDD? AFAIK they differ in hardware somewhat.
Touchpad scrolling works for me, as does circlar scrolling. All I did is pacman -S xf86-input-synaptics and afterwards I fiddled around with synclient.
Multigestures don't work right now, and I don't have much hope that it will, given that I didn't even get them to work with Win7.
I'll try the brcm80211 driver later, when I'm back on wired LAN, and I'll post details on the adapter, too, even though I suspect it does not have anything to do with the drivers.

I have the 1.7GHz w/ 250 HDD, I didn't even know there's a 1.8GHz version.
I am also dual booting with windows 7. I noticed that if I turn wireless off in windows I can't get it to start in arch but as long as it's left on in windows when I turn it off the wireless works fine in arch. I got the multigestures to work in windows 7 you have to install the alps driver software from the acer support page, you can then set the gestures up in Mouse menu in the control panel.
Wierd, I also have xf86-input-synaptics installed, but when I run synclient I get:
Couldn't find synaptics properties. No synaptics driver loaded?I'll figure it out sometime.

Solved this one.
acer_wmi module was the culprit. Whenever I unblocked the card, it'll go ahead and block it again.
Simply
rmmod acer_wmi
rmmod rfkill
and it'll work.
@whitethorn: Yeah, the 1.8 model is pretty new.
I'll look into your issues with synaptic. For me it worked pretty much out of the box, though.

I'm having the same issue.
rmmod acer_wmiallows the wireless to work, but disables all power management and significantly reduces battery life (not to mention makes the laptop run a lot louder and hotter)
Any way to keep acer_wmi AND have wireless working?
Offline
is there any other way to solve this issue?
Im using "brcm80211" driver.

I have a BCM43225 too (Acer 1830T, core i5), I use the brcm80211 driver, and since kernel 2.6.38.3, it freezes my laptop (when a scan is made, I think).
Is there an issue ?
I have to downgrade kernel to 2.6.38.2, but it's not a good solution.
NB : I have tried wl driver, but it doesn't power on after a pm-suspend.
Thank you for your help !

I need to solve this... removing acer_wmi module is nod good for battery life...
