Hi Per,
This has been discussed on this forum quite a few times.
To answer your question, you basically have two choices:
1) As you mentioned, you can share your PC's wireless connection using its ethernet port.
The method to implement this varies by operating system and version, so to explain how
to do so is beyond the scope of this forum. Suggest you use Google to find how to do it.
2) You can connect a WLAN bridge and use that. I personally use the Netgear WNCE2001:
http://www.netgear.com/home/products/wireless-adapters/high-performance/WNCE2001.aspx#This is inexpensive and works well. However, there are other solutions on the market.
The RRC itself should not need any changes, unless you are on a fixed IP. In that case, I suggest
that you change it to DHCP.
There will soon be an internal WLAN add-on card solution for the RRC, but it is not yet released and
pricing has not been announced.
