Looking for expert u-verse opinions on wiring and setup for optimal use of both TV network and LAN

Looking for expert u-verse opinions on wiring and setup for optimal use of both TV network and LAN

 

Posted this inside another thread but I only received one reply so I'm starting my own with it....

 

 

 

I'm also interested in what is the "Optimal" cabling structure to get the best speed and quality for not only the TV service, but also the computer network side of things.  I came from Comcast and had 5 STB and 1 cable card on the TV side and a Gigabit wired/Wireless N network on the computer side.  Everything worked flawlessly before the U-Verse install. 

 

U-Verse newbie here and I'm having some services issues/problems with losing the internet service, wireless STB connectivity and other STB connectivity to the DVR....like picture freezing during playback or just dropping the ON Demand channel and going back to the menu.   The problems come and go and I'm trying to decide if the entire system was marginally installed.  When the tech came out to do the install we had to make some concessions as to how the equipment was laid out based on my existing wiring or lack thereof. 

 

Backgroud:

U-Verse layout as it is now.  Copper lines from the street to COAX (RG6 not Quad Shielf) at the NID (I guess that's what it is called) on the outside of the house.  The COAX runs to the RG on the second story of the home...the RG feeds the STB/DVR over Ethernet with HDMI output to the TV in that room.  There is also a U-Verse Wireless Access Point pluged into the RG Ethernet that supplies two wireless STB in adjacent rooms also on the second story.  The install tech run a new  AT&T supplied RG6 from the NID 100 feet to an AT&T splitter that feeds 3 more STBs (1st floor) over my existing coax.  I'm assuming he also installed the "Diplexor" in the NID to feed the new run of COAX to the 3 downstairs STBs.

 

Since it was installed this way, how does that compare to an optimal solution? I'm willing to do some new RG6 Quad wiring to all areas that the STBs reside in to a "Home" run location to put the RG and DVR/STB.  Would this be better?  I'm guess I'm trying to get all the STBs serviced over the RG6 network to free up traffic on the Ethernet side...I guess this is basically the same way as my Comcast install.  Right now any of the STBs accessing the DVR are tying up Ethernet traffic on the non-Gigabit switch in the RG.  That hardly seems optimal. From reading the above posts, it seems as though running all the STBs off of Ethernet is the way to go. 

 

Right now for the internet side of things, I have turned off the wireless in the RG and connected my DIR655 Gigabit Router (DHCP off) LAN to LAN on the RG  and letting the RG do the DHCP and routing.  All my wired Ethernet (pre-existing) is wired to the DIR655 and getting IP addresses through the RG. 

 

With the setup I have now, both TV and computer network, I'm having these issues come and go.  Soliciting all opinions here on which way to go.  If things are already optimal then I guess the alternative is to just go back to Comcast.

 

Thanks ahead for your input and replies.

Was really hoping that an "Expert" U-verse would provide some comments.  I have quickly put together a diagram of how the install is now and a possible rewiring based on a comment in the thread below.

Your proposed solution will separate IPTV and Internet traffic, which could help your computers.

However, there is another option instead of running RG6 from the NID to the RG -- you can also run Cat5e instead. This may have lower errors than coax for this run. However, you will need a different balun in the NID, AT&T will have to come provide that for you.

Thanks for the reply SomeJoe7777.  I have been following your posts in the other thread on how to use other routers with Uverse and I was about to pick your brain on the networking area. I think I will go ahead with the proposed solution and also look into running a Cat5e cable from the NID to the RG as well so it will be in place if needed.

 

On a separate note, should/do the two different networks be on their own subnet?  I'm not a networking guru so could you provide an example of such.  I have my DLink 655 configured as an AP with the DHCP turned off and assigned a static IP right now of 192.168.1.1 and the RG is 192.168.1.254 doing the DHCP and handing out addresses from 192.168.1.64-253.

 

Thanks in advance.

No, they don't have to be on different subnets. They just need to have the RG separating them, so that the multicast traffic on the IPTV side won't interfere with the computer side. Having all the TV receivers on one of the Ethernet feeds from the RG and all the computers on another accomplishes this.

Re: Looking for expert u-verse opinions on wiring and setup for optimal use of both TV network and L

SomeJoe7777, you seem to be one of the "go-to" guys around this forum, so I figured I would reach out to you directly.

 

We have U-verse for TV and for internet.  We have the 3801HGV.  We have 4 HD set top boxes.  One is a DVR and the other 3 are regular (clients?).  I may be adding a couple more TV boxes (if possible) to the mix in the near future as well.  I would like for all TV boxes (now and future) to be hard-wired.  Our home was pre-wired with a minimum of (5) CAT 6 at each TV location, and everything is a homerun.

 

On the computer side we have several devices that will be hardwired Ethernet connections.  Some require it and the others I would like to hardwire for reliability..... i.e. TV's (for “smart” TV functionality), an A/V receiver, multiple desktop PC's, a Blu-ray player, multiple media players (4), a NAS drive, etc....

 

Also, I would like to have wireless N, which (as you know) does not come on the 3801HGV.  We have a couple of laptops and several tablets scattered around the house that will require this wireless.  Also we have a couple of wireless internet radios.

 

So….. what do we need as far as equipment goes and how the heck do we connect it all?  Imagine that you are creating a network from scratch. Our priorities are  reliability, flexibility for future add-ons, speed and a network where conflicts between devices are eliminated or at least minimized.

Do we separate all the TV from the “other” stuff?  Multiple switches?

I immensely appreciate any and all input given on this!

murfsky - Half is simple half is complicated, The wired is simple - Keep the TVs & computers separate. One path back to the RG for each. Use a switch such as this on the TV path & one on the computer path. http://www.amazon.com/dp/B00006RVPW/ref=asc_df_B00006RVPW1644937?smid=ATVPDKIKX0DER&tag=hyprod-20&li...

Setting up the N wireless is beyond me. Somejoe can explain. But, why not try the base wi-fi first. N is almost the latest & greatest ( or go for AC). B or G should be adequate which you can extend easily with this http://www.att.com/equipment/accessory-details/?q_categoryid=cat2990041&q_sku=sku6610387&q_manufactu...

Maybe you could use it to broadcast N. Somejoe, what do you think?

Re: Looking for expert u-verse opinions on wiring and setup for optimal use of both TV network and L

Hi murfsky,

1. How many total Cat6 cables are coming to the central location? (Whether they're going to be used or not)
2. How many of these Cat6 cables will be connected to an active device (either IPTV or computer)?
3. How many are IPTV, and how many are computer or other Internet device?

Re: Looking for expert u-verse opinions on wiring and setup for optimal use of both TV network and L

1. probably..... 5 from each TV location..... maybe a total of 20
2. I am guessing probably 3 will be used at each location
3. 1 will be for Uverse set-top TV box , 1 for a media player (maybe a mini PC or a Raspberry Pi), 1 for TV (ethernet jack on back of TV) and possibly one for an HDMI balun

Why do you ask SomeJoe? You have me very curious....

Re: Looking for expert u-verse opinions on wiring and setup for optimal use of both TV network and L

murfsky - For the same reason you asked him in your OP, because when it comes to networking he is the man. Also, because I kind of jumped in & tried to smooth it over. I picked up the first part from various posts. Also, the repeater.

The repeater is really easy to set up. Whereas, I see people going crazy trying to set up wired routers to work with u-verse and somejoe is the expert in helping them. I believe I saw a suggestion that the repeater should be on a different channel than the 3801 base wi-fi. So, why not on a different band.

If a b/g 3801 is working with a b/g/n Netgear WN3000RP, will the Netgear communicate with a device set to N? I thought somejoe might find that an intriguing question.

I may see if I can set it up.

With 20 network cables and a variety of devices, I believe that the central unit that will best meet these goals while remaining cost effective is a small business 24-port managed Gigabit Ethernet switch that can make use of VLANs.

 

My recommended choices would be:

 

1. Dell PowerConnect 2824, $289.00

2. Cisco SG200-26, $279.99

3. NetGear GS724T-300, $192.99

 

The NetGear is probably not as well-tested as the two big names, i.e. you get what you pay for. Smiley Wink

 

 

I would configure this switch to have two VLANs, make them VLAN ID 1 (computers and Internet devices) and VLAN ID 2 (IPTV).  Configure the ports as required, and uplink the switch to the 3801HGV twice, once from each VLAN.  This will separate IPTV and computer traffic.

 

Disable wireless on the 3801HGV, install your own 802.11n wireless access point (or points) wherever you'd like, uplink it (them) to the switch on VLAN 1.

 

If now or in the future you want to use your own router for the computer/Internet devices, you can insert it into this setup in between the 3801HGV and the switch on the VLAN 1 uplink.

 

This setup will give you complete separation of computer and IPTV traffic, maximum flexibility to connect any Ethernet cable to any VLAN, enough ports for all cables, Gigabit speeds between all computers, 300 Mbps speeds between computers and wireless devices, flexibility to add a router, and the ability to run tagged frames to downstream switches if a circumstance arises where you don't have enough Ethernet cables to a particular location.  (This would allow a downstream switch to run both VLANs on the same cable and therefore extend the dual-VLAN setup of the central switch to any remote location).

Please don't interpret my silence as disrespect or as a lack of appreciation.... 

I am trying to wrap my head around alot of what you have said....   Even though I have been desperately researching terms since your last post, I am not entirely confident in my knowledge of certain key points.  I am not familiar with VLANs... Also, I am not really sure what you mean by "uplink."

 

Would there be any way for you or someone to create some kind of visual flow chart to demonstrate these concepts and ideas?  I fear that I am just too new to this arena.  I appreciate your trying to put things into laymen terms but it is still a bit over my head.
