Hi, I have a netgear WNDR3400 100nar router, dual band, 2.4ghz and 5ghz. I set up 2 connections. On the 2.4ghz I set up a WEP connection with 64 bit encryption for my wireless repeater (WNR2000). On the 5ghz i set up WPA2 for regular use. Unfortunately my computer does not support 5ghz or atleast i dont think it does. My samsung tv picks up the 5ghz so I connected to that, the macbook pro connects to the 5ghz. The other computer I want on the 2.4 ghz with the repeater. Hardlined via ethernet anything and everything works. For some reason 2.4ghz wont connect wirelessly and does not even give me the option to enter the hex key. just says unable to connect. the 2.4 doesn't work on anything (currently the repeater is offline until I can fix this issue). Infact, ignore the repeater info. I think there is a problem with the distribution of the IP addresses. Could they be overlapping between the 2.4 and the 5? The next item on the network (tv) using 5ghz, occupies sequence 2 under the ip address....whatever the default is it would occupy 192.168.1.2. I have reformatted my computer, uninstalled and reinstalled network drivers, as much as I could do with the computer itself so I'm assuming it is the router. I've disconnected it and reconnected it, reset it, redone the whole network multiple times, renewed the IP address. What is going on? Can anyone help me please.
