Each receiver playing for 5 seconds after channel change then freezes

I'm on day two now. Yesterday was fine but I started having a problem today with the receivers. They play for a few seconds after a channel change and then freeze. If I change channels it then works for a few more seconds. This only happens on my two non-DVR STBs.

My internet connection is fine, getting a solid 23/3 mbps without any packet loss, 20 ms first hop ping. That's tested using the same CAT5 lines the receivers are on.

I also rebooted the DVR.

schmick - Strange - You have tried a reboot?? Best do whole house. Pull the power on RG, DVR & ant STBs/WAPs. Replug RG % wait for all green, Replug DVR & wait for reception of channel. Replug the rest.

@niconieto , your problem is that you have connected your DVR and/or other TV Receivers back to the RG through your Airport Extreme. The AE (like most consumer routers) doesn't know how to handle the multicast traffic and IGMPv3 requests necessary for U-verse IPTV.

So no matter what I need to run a cable directly from the modem to the box.
I also try activating IGMP Snooping on the AE and didn't do anything.

Nothing else I can do?

thanks

The AE apparently doesn't handle the IGMPv3 protocol correctly. I know it has that option, and there's an ASUS router with similar options, but I've not heard from anyone that they actually work properly.

You can connect the TV receivers via a Gigabit switch, but not via a router. You should also not connect them to the same switch that your AE is connected to (because the multicast traffic may cause the AE issues with networking).

Im having the same issue on my wireless receiver. Channel plays for a few seconds then freezes. I change the channel and it plays for a few seconds and freezes again. I have the DVR, access point and an airport extreme connected to the NVG589 modem. What could the issue be?

Assuming you have the devices connected as you described (all three connected directly to the Residential Gateway (the NVG 589), I would unplug the power cord for the RG, the WAP and the wireless receiver, then plug them back in, in that order.

If that doesn't work, you can try http://ufix.att.com , it may have a suggestion. If it doesn't, I'd try clicking this AT&T logo U-verse Customer Service link to send a Private Message (PM) to the AT&T customer service team to help you resolve your issue. You can expect a reply via return PM (the blue envelope in the upper right hand corner of this site, next to your name and avatar) in a business day or three.
