I have a Linksys E3200 which works with OpenWRT, but wireless is completely unsupported (b43 driver says FOUND UNSUPPORTED RADIO (Manuf 0x17F, ID 0x2057, Revision 5, Version 1) ), as also documented in the Linux kernel wiki (search for BCM47186B0). A developer that wants it for free (any reason, not necessarily fix the wifi driver. Shipping free as well if <= 30 EUR) can contact me.
