Yes I have noticed this with RDM. I'll make the cast motions, and just stays there... till I move around or start casting again. I have also seen the Utsusemi has no effect message. Got to love SE >_<
Not sure if they would, but I am sure just about any of these units are compatible with 802.11g and 802.1b wireless routers. But here is what Netgear has.
