Whenever I turn on a receiver (stb) the RG transmits the Uverse tv stream to the receiver twice: once over the HomePNA interface and simultaneously over the Wireless network. The wireless tranmission is superfluous as I don't have any wireless receivers (they are all connected via house coax cable). It uses up so much bandwidth that no devices can connect to the access point, so I need to suppress it. I have upgraded the RG and tried to use MAC filtering to block the receivers from the wireless network, but neither has any effect. Any ideas on how I might prevent the RG from sending the TV signal over the WLAN?

Are you sure it's not coming from a neighbor with a wireless receiver? As I understand it, the wireless boxes have a seperate "N" wireless transmitter that plugs into an ethernet port on the RG and it's solely for that purpose. You can use inSSIDer to check.

The problem doesn't occur when all set top boxes are off, and always occurs when any of them are on, so it appears to be confined to my equipment. Looking at Settings/LAN/Status at Packets transmitted on the Wireless and HomePNA1 connections, the numbers go up in lock step when a set top box is on, so the same packets must be getting transmitted by my RG on both networks.

AT&T suspected a faulty RG and sent me a new one, but the problem persists. The symptoms include loss of Internet connection while sending/receiving email or Web surfing, and rapid drain of battery power in my phone due to repeated attempts to re-connect to the RG. Looking at packet statistics on Settings/LAN/Status in the RG, the numbers for Wireless and HomePNA1 go up rapidly in lockstep as soon as any set top box is turned on, suggesting that the same packets are being transmitted by the RG on both networks.

They already replaced the RG with a (slightly) newer one which didn't have any effect. Probably a tech visit is inevitable, as from the many hours of online research I have done it appears I am the only one on this planet at least that has had this phenomenon.
Thanks to everyone who has responded.

My configuration is very simple. The RG is the only router I own. Its only input is the AT&T DSL line. The two outputs are coax and wireless - I don't use any Ethernet ports. The coax was installed around 1990 by the builder to make the place 'cable ready" as was the custom then, so it's not cat5e I don't think. The coax cable comes out of the RG and goes to a splitter which sends the Uverse TV signal over three other coax runs which terminate at wired STBs. This is all that is on the HPNA network. I have several devices that regularly connect to the RG via WiFi: a laptop, my smartphone, a printer, and a Blu-Ray player. When I press the Power button on any of the STBs the "Wireless" light on the RG blinks very rapidly, the laptop connection slows down and drops out a lot, and the phone loses its connection and tries repeatedly to re-connect, using up battery power rapidly. Looking at the RGs statistics (Settings/LAN/Status) you can see that packets transmitted on HPNA closely matches those transmitted on Wireless, so the same information is being sent over WiFi as over HPNA - namely, the consolidated Uverse TV signal. If I turn off the STB everything goes back to normal. Maybe the RG sends each packet first over WiFi, then when it doesn't get an acknowledgement (because the STBs don't have any WiFi adapters), resends them over HPNA. Maybe if I could get it to send the TV packets over HPNA first the problem would go away. Or maybe I should get a separate router for WiFi and chain it off the RG?

This is very strange. (Correctly functioning) RGs do not broadcast IPTV over WiFi. They only transmit it out the ports where STBs are responding, e.g. the HPNA Coax and any Ethernet LAN port where an STB has responded.
When using Wireless receivers, there is a seperate WAP used for that, different frequency (5 GHz), different protocol (802.11n).
You can get a flood of Wireless traffic from your own routers when you connect them to the same "leg" from the RG as an STB and the exact symptoms you're talking about.

Thanks, that is some interesting info. If I do get my own router I expect I will chain it off one of the RG's Ethernet ports, so that would be a different "leg" than the STBs. Probably the best thing I can do now is schedule a tech visit. Thanks again.

I did the reset to factory default with no problem, then did some data gathering and calculations to measure Wireless and HPNA transmission rates with a STB on and off. I did this by looking at Traffic Statistics for Wireless and HomePNA1 on the Settings/LAN/Status page, taking readings at one minute intervals. Here is the data with one STB turned on:
TIME Wireless Pkts Delta HomePNA1 Pkts Delta
12:57 41940 41922
12:58 72960 31020 72926 31004
12:59 104683 31723 104608 31682
1:00 135126 30443 134989 30381
1:01 166271 31145 165936 30947
1:02 198561 32290 198203 32267
1:03 228864 30303 228464 30261
1:04 259416 30552 258971 30507
1:05 290584 31168 290130 31159
AVG w/ STB on: 31080 31026
So, with one STB on the RG transmits around 31K packets per minute on both the Wireless and HPNA interfaces. Here is the data with the STB turned off:
1:08 323197 322440
1:09 323462 265 322657 217
1:10 323684 222 322760 103
1:11 323864 180 322842 82
1:12 324187 323 322946 104
1:13 324476 289 323212 266
1:14 324725 249 323403 191
1:15 324955 230 323512 109
AVG w/STB off: 251 153
So, with the STB off the RG transmits only minimal traffic over the two interfaces and the rates are not correlated. With it on the RG transmits 31K packets per minute over both interfaces with the rates closely correlated. Conclusion: the Uverse TV stream is being transmitted over both interfaces concurrently. Problem to be solved: how to stop the TV transmissions over Wireless.
