Re: ad-hoc wireless connection with Netgear N150 USB adapter
In the meantime I found that the ath9k_htc driver *doesn't support* ad-hoc mode. Unfortunately I missed this information before opening the thread. I didn't find more details on the rtl8192cu. I'll get an AP and try the ath9k_htc driver in AP mode, which seem to be supported. I will update this thread as soon as possible.

ad-hoc wireless connection with Netgear N150 USB adapter
Hello, I'm submitting a problem regarding a wireless connection (ad-hoc) between two computers using both a Netgear N150 WMA1000M USB adapter (rtl8192cu chipset). Setup seem to be correct (I can detect my neighbor's networks) but pinging and trying to ssh between my two machines gives no result, in neither direction. Each computer can ping to itself. I searched a lot on the Internet, I noticed that others have a quite similar problem but I couldn't find an answer, so I'm posting here :-) More information on my setup: - Debian Squeeze 6.0.5, kernel 3.2 (bpo) - machine#1: Pentium4 2.66GHz, kernel 686 - machine#2: Celeron Core 2x2.4GHz, kernel amd64 - firmware-realtek 0.35 (bpo) installed - wireless-tools installed - firewalls are down, I also disabled all wired connections - both modules rtl-8192cu and ath9k_htc seem to work - no WPA enabled - the machines are close to each other (just one brick wall in between) - yes, I also tried with no brick walls in between, using a laptop with the same N150 adapter - and with the same result I'm posting more details below. Is it an incorrect setup on my part, or maybe a hardware issue? Any suggestion will be really appreciated. Thank you, Andrew P.S.

maybe 192.168.15.3 on #2? ;o) :-s ... I'm sorry, this was a stupid copy paste error: of course *they have not* the same address :-) Thanks!

[Corrected post] ad-hoc wireless connection with Netgear N150 USB adapter
I'm sorry for doing a stupid and confusing copy paste error in my previous post: of course the machines do have *different* IP addresses. I'm posting again - with correction.
