I have a netgear n600 and I just bought a netgear n750. My modem is in the office which is connected to the n750. I want to put the n600 in the living room so i can hard wire it to my Xbox, media comp, etc. But I want to be able to connect the routers wireless. I have tried to configure the n600 to be a repeater but I can't seem to get it to work. on top of that the only way Ive been able to even bring up the options of using the router as a repeater, I have to turn the security of the wireless off. i tried downloading dd-wrt but they don't have firmware for the wndr3400v2 Any help would be greatly appreciated.
