i bought a refurb dual band router about 2 years ago and just found it after a move. i tried hooking 4 comps wired but it would only allow 3. can i hook my g linksys router into my e3000 linksys router and make it work that way?the other comps are g so they should work on the dual band, but instead of allowing 4 to be hardwired it only notices 3. can anyone give me some advice and let me know if i can hook another router into one of the wired ports and send it downline? thanks.
