I always do this. Without I often have no connection > since start. Please stop doing that unless you are debugging something. The default (11n) should just work, and we need to hear about cases where it doesn't. I don't think 11 is a problem in your case, it is something else. Though I cannot really pin-point it :-/ > My AP is a IPFire 2.23. The Wifi Adapter for this machine is a "usb: > Ralink Technology, Corp. RT5572 Wireless Adapter". Running an AP with a USB stick is genrally not a great idea. If you use a different AP, does the issue go away? (Yes, I know other clients are working just fine with this one. I am looking for data points, not trying to make you switch over to something else.) > The Ipfire image can be downloaded on ipfire.org. > For testing I allowed all outgoing traffic from my laptop to the internet. > > Indeed I now one person who has quite the same network infrastructure as > me and his OpenBSD works perfectly. Good. If you can, please go there and try it, and if it works show us which of the counters end up being different. That might help us figure out what's wrong in your setup. I'm afraid I can't make better recommendations based on what we know so far.
