Here's a tweak I found for my JasJar so that I can see the status of my WiFi connection on the today stream.

using a registry editor (I use Mobile Registry Editor) add the following:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Today\Items\"Wireless"]
"DLL"="netui.dll"
"Order"=dword:00000000
"Enabled"=dword:00000001
"Type"=dword:00000004
