All versions of the RRC-1258, RRC-1258MkII etc. can be equipped with a internal WiFi Interface. A WiFi interface is convenient when you want to connect the RRC:s to a WiFi network both at home or when traveling.. You do not need any extra cables or boxes. For the Control-RRC the main reason to use WiFi might be the portability, and for the Radio-RRC to physically separate the RRC from the telephone/DSL line which is the most common route for lightning storms to hit the RRC and the Radio.
The WiFi Interface is mounted on the pinheader P3 in the RRC-box. RRC-boxes produced from summer 2012 has the pin header in place from production and no soldering is needed. The pin header are included with the WiFi Interface in case you need it. Instruction for installation is done can be found on the Remoterig website under Support/Mods (hardware).
The 2.4 GHz Wifi Interface is compliant to 802.11b/g and single stream 802.11n and supports WPA2- (AES), WEP (64 and 128 bit) modes of security in infrastructure mode and also TKIP in SPI mode.
There is no limitations compared to Ethernet, all settings that are used when they are connected to Ethernet can be used. The WiFi Interface do not support ad-hoc, so it’s not possible to connect a Control-RRC and Radio-RRC direct together with the internal WiFi Interfaces you need a Access point or a router also.
The RRC automatically or manually switch between WiFi or Ethernet. IF it’s set to Auto and the Ethernet is connected, Ethernet will be used.
