I’m having all sorts of problems with both a dlink 615 and a tp-link tl- r740n. I’ve tried different dd-wrt builds but none of them seem to work with your system. Can you advise on a cheap recent wireless router (not linksys) and a dd-wrt build that DEFINATELY works with your system. I’ve wasted hours on trying to get these 2 routers working to no avail!
