I am providing wireless access to a large outdoor gathering. I have enterprise grade outdoor gear to handle the access points on 2.4ghz and 5ghz. I'm concerned some customers may not have wireless networking gear, so what I need is a wireless bridge that doesn't repeat and step all over my enterprise AP channels/QoS profiles... most of the SOHO bridges I've reviewed are forced into repeater mode. I would prefer the bridge to only have 1 ethernet port, be dual band, no repeater, connects to any wireless network (brand agnostic), and be as cheap as possible. I'm not adverse to installing ddwrt or tomato if required, but I'd prefer a stock solution. Any suggestions?
