For some time, the recommended wireless network for Rhodes staff, postdocs, and guests has been the ru.ac.za wireless network. This network is now deprecated in favour of the eduroam wireless network, which has been offered at Rhodes for several years and has been the only wireless network available to students since the beginning of 2013.
All new devices (laptops, tablets, phones, etc) should be configured the use the eduroam wireless network rather than the old ru.ac.za one.
If you are currently using the ru.ac.za wireless network, you may continue to do so for the time being. The old network will not be discontinued until early 2014. However, when the opportunity presents itself, you are encouraged to switch to using the eduroam wireless network instead.
Changing from the ru.ac.za to eduroam network is simply a matter connecting to the new network. You will not need to re-register your device on the network, and the services that are available to you when at Rhodes are identical on both networks. The only real difference between the two is that you have to add @ru.ac.za after your username when connecting to eduroam, whereas this is optional when connecting to the ru.ac.za network. This is so the network knows you're from Rhodes rather than, say, UCT.
