good evening,
i've got  1 rb113 that i use as wireless router with 3 atheros cards. i use only one ethernet but the throughput of ethernet is very low (like 8 Mbit/s!!! ), it's possible to remove vlan tagging to get more throughput, i've looked that, cpu usage when i do data transfer is hight (like 90%!).

Anyone has any ideas?

Regards
Giuseppe
