I just bought the Dual band N600 WNDR3400v2 based on some great review. However, during the setup, I realized that that router does NOT give me any option to pick the WEP as the security option. While most of my devices can support the newer WPA, I do have some legacy wireless devices that can only work with 40-bit/64-bit/128-bit WEP. Is it true that Netgear remove the WEP support in all new devices? My firmware version is V188.8.131.52.
