I've just bought the Edimax EW-7811UN Nano wifi dongle and I am having difficulties creating an ad-hoc connection between my macbook and the raspberry pi.

I have read conflicting information regarding the compatibility of my dongle. Has anyone managed to get it to work in an ad-hoc context ?

Are there other dongles known to be ad-hoc compatible ?

Thanks.

Assuming you have an RTL8188-based adapter, you could simply do this:

ifconfig wlan0 up              # Unnecessary?
iwconfig wlan0 mode ad-hoc     # The secret sauce
iwconfig wlan0 essid "My WiFi Name"
ifconfig wlan0 192.168.1.1 netmask 255.255.255.0

Your dongle has an RTL8188CUS chipset. Give it a shot.

Hi EDIMAX 7811UN doesn't support Ad-Hoc mode past the Linux Kernel versions 3.9+ . This has been checked by me and suggest shifting to Ralink based WiFi Dongles. For further information I put this query for reference.

I have to work with RPis and WiFi in ad-hoc modes everyday and it makes sense to buy the right WiFi adapter depending on modes you want it to work with. Also I think old Raspbian Versions 2012 can work with the Edimax but that doesn't seem like a plausible solution on a long run.

Major UPDATE

with Debian Wheezy 7.10 firmware Update, the EDIMAX adapters are now Ad-Hoc Compatible. This has been Tested and Checked today personally!
