Att Uverse Internet + Linksys Router?

I have att uverse internet and it has 4 wired ports and wireless access, but I am up in the attic and the signal is a little week, and I want to run a line out of the tv cable box i have in my room (on the back of the box there is an ethernet port which i have tested and it works for computers or game systems), my idea was to run my linksys wireless router wrt300n.

i have an ethernet cable running from the back of my att cable box directly to my router. the router will show up but has no internet. that being said if i hook my roku or laptop to the box it will connect to the internet, so it is definetly the router

i had it hooked up like this before i moved out then i had it set up with a different modem, and now i moved back to the original set up. whenever i called tech support they had me enter in some numbers on the 192.168.1.1 page. i have reset the router and the cable box, nothing changed

 

If I understand you correctly your cable box has a modem as part of it? If that is the case you need to do a compete new setup of your router to that modem. The fact that the router may work with whatever else is in the house by way of a modem is irrelevant.

Perhaps I just don't fully understand your set up. If you have the original installation disc for the router follow the instruction using the cable box where it says to connect to the modem.

Another thought, is there an actual modem in the house that connects to the internet and if so is there an ethernet cable that connects it to the cable box?

 

the start up disc never really helped with this problem both times. the router is just not passing the internet through it at all. this is a picture of the back of the cable box. http://uverseuniverse.com/wp-content/uploads/2007/07/back_standardstb.gif there is a network port on the right side which allows whatever is hooked up to it to access the internet. but when i hook the router up it will not let the internet run through it (neither through the ports or the wireless).

 

I cannot read what it says on those ports. I see a single ethernet port and am not sure that it is not in input port. The one on the right looks like an HDMI port but if I enlarge it all I get is a pixelated blur. My guess is that the ethernet port is for the box to receive information from a modem and the other to display to a TV. Can you clear this up for me by telling us what each says?

 

i just got that picture online the only thing that matters is the ethernet port which says "network." the other ones are a usb and an hdmi which dont apply here of course. other info that might help the cable box does have a mac address. Is there a normal procedure for hooking up a linksys router to a new modem.

 

Ok I just went and had a look at my own box and manual. I too have an ethernet port labeled the same way. The problem is that is actually serves no function unless the cable provider has allowed for it. There is an asterisk in the manual. What I am afraid you need to do is connect the router to the actual modem (wherever in the house that may be) and go from there. There has to be a physical connection between a modem and a router for the router to work.

That cable box is just not set up that way by the provider. Even then I think it is designed to connect the box to the modem to allow you to view content on the TV. But I am just not sure. If you can provide the actual make and model of the box we can investigate further.

 

Here is your next problem. Most of the modems supplied by the cable companies have only one ethernet output which means only one router. Your best bet is (assuming your computer is compatible) is to change routers. I suspect that the one you are using is Wireless G format. You will get much greater range with a wireless N standard router so long as your computer is also compatible with the N standard.

 

It is a motorola Model# VIP1200

Like i said before I have had my router hooked to this cable box before and had it work perfectly fine. and when my laptop or roku is wired to the network port they do connect to the internet.
thank you for helping me by the way.

 

I guess I am a little lost in this technology, hopefully before morning someone else will.

 

well lets just say that i had a regular modem, disregard it is a cable box, what would the procedure be to hook to hook up a linksys router with the same problem

 

If the router has a built in Modem then you need to turn on 'bridged mode' from within the router page options.

what generally happens with a standard router is that it just broadcasts the wireless signal and you connect via an SSID (which is what the router broadcasts itself as (Netgear) for example but this can be changed and the passphrase
(SSID and passphrase both need to be configured from within the router home page before they work)

A modem/router is slightly different which is why it needs bridged mode enabling
