I ran into a DNS-related problem with dnsmasq (once i had discovered in syslog that NM complained about not finding the dnsmasq binary, so I installed dnsmasq-base). It returned a REFUSED status code upon a client's query.

Define a new ad-hoc WLAN profile, set WEP parameters as needed. Bring up the upstream link first, then Create new wireless network from nm-applets menu and select your previously created ad-hoc profile. AFAIK, NM currently has no built-in way to run a WLAN NIC in master mode to create an AccessPoint/Infrastructure network, so we're stuck with ad-hoc for the time being. regards Marc ___ NetworkManager-list mailing list NetworkManager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

If *anything* else is touching iptables rules on your machine, it could step on the NM's rules unless that program is careful to only undo what it added in the first place.

At the moment, I don't see a compelling reason to use master mode over adhoc until drivers get better. We certainly can't flip the switch until most of the mac80211-based drivers get good AP mode support. While some drivers do have OK AP-mode support, there question is, what advantages does master mode bring, and if those are significant, how do we let the user know what impact master vs. adhoc will have on their day-to-day workflow?

At the moment, I don't see a compelling reason to use master mode over adhoc until drivers get better. er.. I didn't mean to complain about the lack (which I don't consider as such) of AP-mode support. If my words sounded like a complaint, I offer my apologies on the spot. I like NM very much, and it's fun seeing how it gets better with every release: I was stunned how easy it was to get my USB 3G modem working with NM (plug, PIN, works), where it took me half an evening to make it work on MacOS X, half of which figuring out which software to obtain from where and what exactly to use it for... The one thing that springs to mind if it comes to Infrastructure vs ad-hoc modes of 802.11 could be scaleability for a larger number of devices, and another thing might be the lack of WPA/WPA2 support I see occurring in most implementations once you switch over to ad-hoc mode. I'm not quite sure if that is because of the nature of how 802.11 ad-hoc mode works or if no vendor's so far cared about implementing WPA/WPA2 in ad-hoc mode. regards Marc ___ NetworkManager-list mailing list NetworkManager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list
