Hey thanks marek! I'm sorry i didn't think of trying that in the first place. Ath9k_htc has indeed a few issues so i wouldn't be suprised it's the culprit.
I was aware of the battlemesh v5 and last week i even piperlurked the mail archives, but didn't realize it would happen this week. Best luck in athens then! I will continue my little mesh-battle here. Will try static routes tomorrow and report anything interesting.
Cheers, guido

Hi,
i'm participating in the development of a wireless mesh network in Delta de Tigre, near Buenos Aires, Argentina. Landscape is absolutely flat, with dense forest 15-20mts tall. Nodes are being installed along the river, 50 - 150mts apart, with clear LOS at ground level. I collaborated with Nico Echaniz last month, bulding another community network in Cordoba, and given the success, I decided to start one more here. I'm also really thankful with Elektra, for recommending the tl-m3220 to Nico! We chose batman over olsr, in part because of avahi stuff, but also to have a real-world implementation and thus collaborate in testing / debugging :) So far, there are only 4 working nodes, but luckily I'm already facing unexpected behaviour.
I'm sorry for the long email, it's mostly terminal logs. In short, iperf between two neighbouring nodes reports >20mbps, yet running the same iperf between nodes separated by one hop reports inexplicably low <5mbps.

Any ideas, thoughts, pointers? Any additional info needed?
welcome on the list! I admit not having dived into all the details of your mail - the bigger part of the batman team is sitting in Athens at the moment (see battlemesh.org). The best next step is to find out whether this performance issue is a batman- adv or a wifi driver problem. May I suggest you remove batman-adv and repeat the same test using static routing ? If you still see the problem it is the wifi that is not working otherwise we have to fix batman-adv.
