sorry to be late on getting back in.. been very busy.. I've also PM'd MattG and MichaelS again about the link I found and some of the information I've been "reading" at Sling and other sites.
One of the things that appears in the log files as well as the configs, is that *sling* appears to have the ability to tell your PC whether the sling goes local or remote (or is allowed to do so) .. in remote mode it streams out to a server and on to you or back to you.
As for Ipad/Iphone - There was a user that was running a cisco small business firewall and he swore that with his logging, he followed the Video data and it was infact leaving his network and coming back in ... and though he had more than 2 meg upload ability, his ipad would only do 2.1 meg.
For normal Sling use .. since January when I got mine .. mine have *never* streamed video out to the net, unless I'm at someone elses' house connecting to watch.
While I'm also using a wireless bridge as a few others are, with DD-WRT running on the bridged router... in my case my bridge comes back to an access point, which then connects to my main router .. so I'm not doing LAN WLAN bridging on my gateway router as others are ...
at first I thought this problem you guys were having was a bridge issue .. even local lan to wireless lan bridging issue.. but as TonyS tried.. connecting the the PC and the Receiver at the same switch external to the gateway router, external to the bridge'd wireless router .. and with the player still not functioning.. that nixed bridge issues in the bud..
and its that last test that makes me think more on the "local allowed" bit or config option coming down from Dish/Sling as the cause. Even msg.sling.com not responding properly .. or the account data holding corrupted data etc..
All of those types of issues related directly to accounts would have to get cleared off from the server side; so that the next time a user logs on, the server recreates what ever user/cache/account settings.
This account issue first connected problems with getting missing Grid Data to return, or channels to play properly ... this was observed through DishRemoteAccess ... because when you connect there, you connect to a direct servicing server dish XX.sling.com ... currently I'm using dish11.sling.com, others may use dish1.sling.com ... the numbers I've seen are dish1 ~ dish16.
Recently multiple users were having problems getting grid data, and having DishOnline unable to show user DVR content or play some stuff online ... from other threads *that* was also connected directly to user accounts on specific servers having an issue. (ie. I'm on dish11.sling.com and having no problem, another user may also be on dish11.sling.com and they get no guide data, their account gets reset, their next login they end up on dish8.sling.com ... or some other server.. and their problem is resolved)
anyway.. brainstorming away still .. and like I started.. waiting to hear back from Matt and or Michael of Dish IRT for any more info on the "local" connection types etc..
