unwanted wireless tv traffic

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?

Re: unwanted wireless tv traffic

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.

Re: unwanted wireless tv traffic

Yes, the wireless TV is separate - needs a WAP.

My question is how is the problem showing itself?

I believe initial transmission of a tumed channel is "multicast" - that is It is transmitted to all devices via COAX/HPNA and cat5 network connections. This can overwhelm some ancillary switches/routers & maybe has been known to clobber wireless if there is a fault in the RG.

Re: unwanted wireless tv traffic

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.

Re: unwanted wireless tv traffic

embassy2934 - Why not call in & have them remotely test the RG. Then they wil send you a new one. Or, decide you need a tech visit. If you request a tech visit they may say it will be a charge,

Re: unwanted wireless tv traffic

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.

Re: unwanted wireless tv traffic

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.

Re: unwanted wireless tv traffic

embassy2934 - Just to cover the elephant in the room - you do not have any other routers/switched - only the RG??

Your problem sounds like you have a router/switch in a path connected to both computers and STBs. If you need an additional router/switches path should have ONLY computers or STBs.

Re: unwanted wireless tv traffic

From the duplicate post, which has not been merged with this yet:

Doubt the RG is generating Wifi traffic, when you watch tv. Something else is going on at the same time. What all do you have connected to your RG, and how do you have those devices connected to it?

How many are wireless, how many connected via HPNA (Coax), how many connected via Ethernet (Cat-5e/Cat-6), what switches do you have, how are the switches connected to the RG, are there any third party devices connected to the back of the DVR or STB's (Set Top Boxes), through the Ethernet port, if they are connected via Coax back to the RG.

As for 1990's coax, actually Coax dates back as far as the 1920's.

Re: unwanted wireless tv traffic

All I have is the RG.  I don't own any other router.

Re: unwanted wireless tv traffic

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?

Re: unwanted wireless tv traffic

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.

Re: unwanted wireless tv traffic

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.

Re: unwanted wireless tv traffic

Try going to Settings, then Diagnostics, then click on "Reset to Factory Default State". You will need the Master Password off of the RG, to do this.

Re: unwanted wireless tv traffic

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.
