How to force a software update on my set top box?

The software in your dvr is already whatever att last pushed to it.  Similarly for the gateway (although you can force it to re-install it's firmware by pushing the red button on the back for about 10 secs. - and losing any settings you may have made to it in the process).  Try just rebooting your gateway (pull plug for 15 secs. and let it fully reboot) and after the dvr again (pull plug for 15 secs.).

Have you checked your connections? 

Does the gateway have any red indicator lights on the front?

Is the ethernet cable connected to one of the yellow ethernet ports on the back of the gateway and the other end into the network port on the dvr?

Maybe try using  Troubleshoot & Resolve Tool.

In the end you may have to call tech support (800-288-2020) for assistance.

I get a message saying “Uverse signal has been lost”. I go through the instructions on the screen and nothing works. I’m told I need to do a software update of the settop box. I understand there’s a way to do it but unplugging the unit for 5 seconds and plugging it back in, 4 times in succession. Then the software updates. But, it’s not working on this specific unit (Cisco ISB7000). Why?

WHO told you that?  As stated, updates are pushed to the gateway/DVR automatically.  Rebooting sometimes helps and is always your first option.

The AT&T Uverse tech support gal who I spoke to the night before last.

I appreciate your reply. However, during the troubleshooting session with the Uverse tech support person the night before last, they pushed a software update to my ISB7105 wireless box in the living room and it fixed my problem. Last night I tried the TV in the master bedroom and the exact same problem occurred w/that box (Cisco ISB7000, wired box). That tech support person pushed new software to that box and it again fixed my problem. So, my conclusion is that AT&T isn’t “automatically” pushing software to these cable boxes. Problems occur and then they push the software to address the problem. If only they were sending updates automatically, they could cut down on their tech support calls. What a thought?

I'm pretty sure the only thing that fixed your problem was just the rebooting of the boxes which you can do yourself by pulling the plug plug about 15 secs. or pushing on the power button for about 10 secs.  Next time strange things happen with your boxes reboot them.  And if you have to do a full reboot of every device do it in the following order:

1. Unplug the gateway, DVR, WAP, all wireless receivers.
2. After at least 15 secs. plug the gateway back in an let if fully reboot.
3. Plug the DVR back in.
4. Once the DVR is fully rebooted plug the WAP back in.
5. Finally plug the wireless receivers back in.

By the way I don't think for a moment you software was reinstalled or "updated".  Tech support was just following their old standard motto "when in doubt, reboot".

We just got a new tv but the writing isn’t clear like it is on Netflix.  A friend said we may need an updated box???
