J4V3D yes you can configure your SV7 box for wireless use.
You need a Wi-Fi Dongle/Bridge (do a search for Wi-Fi Dongle/Bridge in google).
You connect the dongle to your box after configuring it to your router via your pc first and then your good to go!
Lincsat (search google) is where i bought mine and he helps out alot too with setting up support).
I had problems connecting mine wirelessly initially but that was because i was slightly out of range from my box to my router so i moved the router a little closer and now the wireless works perfect! All channels, no wires, great box!!
I had to connect with an ethernet cable initially to set it up and after that i plugged the wireless dongle in and all works great now!
DMPORTRAIT you should definitely connect with an ethernet cable first (like I did) and then it will say 'connected' and all channels will appear and all IP Status settings will automatically be generated from your router. (you can buy a 20m ethernet cable for around £2.50 on ebay for test purposes). Then if it works with the ethernet cable you know it must be an issue with the wireless. i.e - out of range, interference from other networks, cctv, etc etc so you may just have to move your router closer.
Hope that helps guys Iv only just got mine working after a good few days of trauma so anything i can help out with i will!
Cheers.
