I had a load of bother connecting the GigaJuke to the router via wifi; sometimes it would work, sometimes it wouldn't, connection speed wasn't always up to it either (the wifi dongle looks very directional). Thing is, WEP security is easily broken, so fiddling on with your router's configuration settings to enable it will decrease the overall securty of your network.

I tried homeplugs (my apartment is built like a concrete-covered Farrady cage so I use them everywhere else, and they are great) but, in the case of the GigaJuke that was a configuration nightmare too.

In the end I bought a long enough stretch of cat5 and just plugged it into the router, worked first time, works every time.

Hope this helps
