Wireless mesh networking on Raspberry Pi using batman-adv protocol

Question

So I\'m trying to setup a wireless mesh network using Raspberry Pi\'s, with the Edimax EW-7811Un WLAN Adapter and the batman-adv protocol.

I\'ve tried following the

Answer 1

I can confirm, that this is an issue of the latest rtl8192cu driver. I was using an older version of that driver for edimax wlan adapters with batman working (almost) fine. But I found, that under certain circumstances (with heavy load), the connection failed. Then I upgraded to the latest version of that driver (date: September 11th 2013) but found that batman wasn't working any longer (in the exact same configuration as with the older driver). The symptoms were exactly as you described in your post.

Edit: My post was deleted, saying that I don't give an answer to the question. I disagree with that: this IS an answer to the original post. The only question in the original post was this: "My adapter is using the RTL8192CU driver. Could this be the cause of the issue?"

Again: I can confirm that using this (latest) driver causes the issue. This driver is incompatible with batman. The issue has nothing to do with the configuration file. Try to look for an older driver or -better - use a wlan adapter with a different chipset.
