Your question is one for a new thread nollie I am afraid as it isn't WooshBuild related. If you cannot ping your providers server it could be blocked by your isp but is unusual.
When everyone understands that IPTV is available on any image it will become easier, IPTV isn't a WooshBuild thing.
IPTV is added to your box by contacting an IPTV provider. They will tell you what you need to do to add it to your box. This can be in the form of the xtreamTV plugin, M3U, bouquet or a plugin which installs the bouquets and all of them normally require you follow the providers instructions, normally using putty / telnet.
WooshBuild has no limitation on which provider you can use, they just need to be able to help you add it to your box.
