Hi ACC25442, to ensure a good communication between your Slingbox and your network make sure that the Slingbox is properly attached to your network.
If you use Slinglinks use the troubleshooting below to make sure that they are working properly.
Here's another nuance I've just discovered. I have 5 slingboxes (!) at home, including 2 Pro HD's and 3 older models. I can remotely connect reliably to all of them in the morning and early afternoon, but come about 5PM local time I can no longer access ANY of them ("Network Error", "trouble Connecting...," etc..) Ene logging into a different link via a firend's website will still not let me connect. In addition, I have 2 IP security cams- I can connect to the one that's connected wirelessly to the Router, but not the wired (Ethernet cable through a switch) one. Also have a Belkin @TV widget in the mix (hardwired), same timing and issues as with the Sling widgets.
Granted, I have a relatively complex network- 1 4-port Netgear 4500, each port connected to an 8-port Gigabit switch. The Slingboxes as well as the problematic camera all go through a secondary Gigabit switch (2 different ones) .
I just cannot envision any hardware issue on my end that would result this temporally dependent behavior. It has occurred now for three straight days. Doesn't matter whether i use the older Slingplayer app or one of the newer browser based plug-ins, same issue. I have never noticed the issue when at home within my own network. The only "IP Switch" issue I've ever noticed was with my TiVo in updating reliably, a direct connection through only 1 gigabit switch seemed to solve that (at least for a while).
Anyone have any clues or other diagnostic procedures I can go through? Could the local ISP here (Cox) be disabling streaming at certain times of the day (but then, why would one camera work and not ther other)?
