Playing with 1.28.7486.2. I have 2 E3000 mostly using WDS mode. Played with WEB mode due to another thread. In WDS mode all items connected to my slave router that is in my entertainment center work fine. Denon 3808 internet music server works perfectly. In WEB mode I have to turn off ARP binding in the main router in order for the streaming to work. In every other way the Denon works. I can access it via wireless connection. Access its setup information, even select radio stations via my laptop. But the server says its disconnected when it tries to play music. Turn ARP binding off, works fine. The thing that gets flakey with WEB mode is the main router "sees" the IP of the slave, does not really "see" the IP of the slave attached devices. I do not know how to unravel the mystery in regards to how ARP works when in WEB mode. I prefer WDS because in WDS mode each device whether attached to the main router or the slave routers is seen as a separate device. Makes bandwidth monitoring, etc., credible. In WEB mode I can only monitor the slave's IP and not attached devices. However with dual mode routers like the E3000 I still keep wireless AP access on the slave. The WEB is done via the 5ghz channels. So in that regard WEB still acts like WDS mode. IMHO the ARP not working in WEB mode is not a bug. I believe it is working the way it simply works. Would just like to understand why.
