My goal is to build a wireless bridge (WPA2 encrypted), bridging a complete vlan trunk with draft-N speeds. I currently have this setup with two foneras running openwrt, but the throughput is only about 1,3MByte/sec.
I will be able to do some tests with two WL-500Ws of a friend, hopefully in a fews days.
Normally I would install openwrt, but openwrt currently does not seem to support any draft-N mode, while Olegs firmware should be capable of it.
If the stock firmware does not work correctly, Olegs firmware offers a lot of possibilities to fine tune you setup (custom scripts, ...).
I will report the results here, when I'm done.
