Hello Ruben thanks for your help!

This is the output from batctl o
I actually tried other USB sticks aswell, but did not get rid of the issue. I am using the Ad-Hoc modus to answer your question.
Thanks for your help so far, do you have other suggestions for me? Richard

VDid you double-check for hardware-issues? Might be a compatibility issue with you wifi hardware.
What are you link values between each peers? (batctl o where row 1 is equal row 2)
Which wifi-mode do you use? Did you tried 802.11s instead of adhoc or vice versa?
Did you tried batman L2 pings instead of icmp-ones?
Best regards

Hello there
Hallo (deutsche Version unten)
I have a simple batman setup that does behave odd:
Raspberry b+, jessie, batman-adv2015.2 witha single LOGILINK WL0084B USB wifi stick attached
I have 5 rasperries that can see each other via wifi (one of them is a gw(BASE2), one of them (SHELF_1) is not directly reachable by the gw, because they are in a line from one room to another and has to be reached via one single hop in between)
digraph {
{ "BASE_2" } "BASE_2" -> "SHELF_3 @ ra" [label="1.689"] "BASE_2" -> "SHELF_5 @ Bar" [label="1.689"] "BASE_2" -> "SHELF_2 @ CD Regal" [label="2.161"] "BASE_2" -> "SHELF_4 @ Toaster" [label="2.161"] "BASE_2" -> "SHELF_1 @ Chris" [label="2.040"] subgraph "cluster_SHELF_3 @ ra" { "SHELF_3 @ ra" } "SHELF_3 @ ra" -> "SHELF_5 @ Bar" [label="1.192"] "SHELF_3 @ ra" -> "SHELF_4 @ Toaster" [label="1.328"] "SHELF_3 @ ra" -> "BASE_2" [label="2.277"] subgraph "cluster_SHELF_4 @ Toaster" { "SHELF_4 @ Toaster" } "SHELF_4 @ Toaster" -> "SHELF_3 @ ra" [label="1.037"] "SHELF_4 @ Toaster" -> "SHELF_2 @ CD Regal" [label="1.483"] "SHELF_4 @ Toaster" -> "SHELF_5 @ Bar" [label="1.175"] "SHELF_4 @ Toaster" -> "SHELF_1 @ Chris" [label="1.371"] "SHELF_4 @ Toaster" -> "BASE_2" [label="3.446"] subgraph "cluster_SHELF_1 @ Chris" { "SHELF_1 @ Chris" } "SHELF_1 @ Chris" -> "SHELF_3 @ ra" [label="1.170"] "SHELF_1 @ Chris" -> "SHELF_5 @ Bar" [label="1.020"] subgraph "cluster_SHELF_5 @ Bar" { "SHELF_5 @ Bar" } "SHELF_5 @ Bar" -> "SHELF_3 @ ra" [label="1.045"] "SHELF_5 @ Bar" -> "SHELF_2 @ CD Regal" [label="1.393"] "SHELF_5 @ Bar" -> "SHELF_4 @ Toaster" [label="1.203"] "SHELF_5 @ Bar" -> "SHELF_1 @ Chris" [label="1.226"] "SHELF_5 @ Bar" -> "BASE_2" [label="2.898"]
}
The problem is, when pinging ANY of the clients from the base (or any client from any other client) I always have a package loss of roughly 50% with a ping reply time up to 10ms sometimes (BASE2 -> SHELF_1, the closer ones are faster). To make things worse, the connection is so weak, even a ssh login may bring it down.
I tried quite a few different settings and already updated to the new version and used multiple USB sticks - the result always stays the same. Now I am out of ideas and I would appreciate some new ideas.
GERMAN:
Ich habe hier 5 Raspberries die sich gegenseitig sehen können (einer ist eine BASIS (BASE2), einer davon (SHELF_1) kann von der Basis nicht direkt gesehen werden, weil sie von einem raum zum nächsten immer größere Distanzen überwinden müssen).
Das Problem ist nun, dass wenn ich irgend einen client von der Basis aus pinge, oder irgend einen client von einem anderen client pinge, dass ich rund 50% package loss mit bis zu 10ms antwortzeit habe. Die die sich näher sind funktionieren besser (2ms) die weiter weg sind schlechter. Ich kann nicht mal mit einer ssh konsole von BASE2 auf SHELF_1 so dass ich da sinnvoll was eingeben kann.
Ich habe schon einige verschiedene Optionen durchprobiert, wie Beispielsweise Update von 2015.0 auf 2015.2, sogar zwei USB Sticks pro Raspberry PI, aber das Problem bleibt. Nun würde ich um Input bitten, mir sind die Ideen ausgegangen.
Danke
Thanks a lot!
