You have a lot of different things going on here.
First, your provider is AT&T so you have ADSL service.
Comcast supplies their service over cable.
AT&T should have provided you with an ADSL modem that is connected to a phone wire. Normally another cable (ethernet, patch, RJ45, Cat5) connects the modem to the network card in your computer.
I don't know what model of router you have but there are 2 possiblities as to type. It can be a regular wireless router or it can actually be a cable modem with a built-in router.
If this is a normal router it will have a port labelled either Internet or Wan (normally, some companies do strange things), you should connect the cable from the ADSL modem to this port.
If it does not have a Internet or Wan port but has a round screw type cable connection, you have no way to connect this to the DSL modem and it will not work for you unless you switch to a cable provider. Even the it may not work because some providers check the MAC address of the unit and will not issue it an IP address unless it matches the one in their files.

Ok, lets say this is a normal wireless router. You have the phone line going to the ADSL modem and then a Cat5 cable going to the Wan port of the router, you are not out of the woods yet because most desktops do not come with wireless hardware. You need to get a Wireless PCI card and install it or if you prefer they also come in USB.

Done? Probably not. If this was a used router it was probably configured at one time and you will not be able to connect to it unless you happen to know the security key. This means you will have to reset the router back to factory default and configure it from scratch. Of course you could luck out and security was never configured for this router but you should still configure it unless you want everybody within range to be able to connect to your router and possibly your computer.

If after this long winded explaination you still want to do this, get back to me with the specific make and model of the router and what operating system you are using and we can go from there.

Hi. just got cable internet (Comcast) and am


that's normal, wireless is normally between 1/4 and 1/2 the speed of your wired connection. normally the router gives priority to wired devices, but this should not cause you any further slow down unless you have wired devices plugged in at the same time you are using wireless. this can be changed from your router's admin page.

Belkin G wireless Router


Do you have an all-in-one router from Comcast? For example, do you have the cable (RF) line and your PC plugged into the Comcast router? If so, unplug your PC from the Comcast router and connect the Internet port of the Belkin to the ethernet port on the Comcast router. Then plug your PC into the LAN port on your Belkin.

[PC] ---> [Belkin] ---> [Comcast] ---> Internet

Once you have connected your boxes as displayed above, you will need to power everything off and bring up the boxes in the following order:

Comcast (wait 60 seconds)
Belkin (wait 60 seconds)
PC

If you cannot get out to the internet, momentarily press the reset button on the back of the Comcast box. Comcast routers are weird. A poweroff should reset the router but I have seen a few times where nothing works until the reset button is pressed (this is also recommended by Comcast).

I hope this helps.

You will need to use the MAC address of your PC. Do an IPConfig/all while connected with a ethernet cable. That's whatg you need to put in under Wan--> WAN MAC address

Please help...internet won't connect


You may be running into a problem of your ISP only allowing one computer on the internet. while the internet is on can you access the internet from the desktop comcast originally setup?  If so that is more then likely your problem.

I have comcast myself and they told me they do not allow home networks. I fixed that problem by using the mac address cloning feature in my router.

The setup cd is also junk, all you should really need to do is:
1. unplug modem, router, and turn off computers
2. Plug modem into router
3. Plug computers into router (don't worry about wireless right now)
4. Turn on modem, wait 20 seconds or so for lights to set,
5. Turn on router. again wait for lights to set
6. Turn on ONE computer that is hard wired into the router
7 Try to surf the net.
8. If successfull try to connect wireless computers (Without using cd) and see if they surf.

If not call comcast and see if your computers are trying to obtain real-world ip's instead of LAN ip's like they should.
If so, you'll need to enable DHCP on the router.

UNABLE TO CONNECT TO THE INTERNET THROUGH COMCAST


To setup your router
first check..
Connect Cable modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active. If it is not, contact your Internet Service Provider. If it can go online,
to setup connectionwith router ..
Step 1:
Connect the Cable modem to the router’s WAN or Internet port.
Step 2:
Connect the computer to any available numbered port (1, 2, 3 or 4).
NOTE: In this example, we’ll connect the computer to port number 3.
Step 3:
Make sure the power adapter is plugged to an available power outlet.
Step 4:
check if you are able to go online wired..
if not your router has to be configured first,
you can also try power cycling your network set up,
Press and hold the reset button in your router for 30 sec with a pen or a paper clip with the power cable connected, then disconnect power for your router wait for 30 sec and then reconnect in back, restart your pc waith for all the lights to become stable in your router, then check if you r able to go online..

2wire Wireless router not working w/Comcast cable modem


Its almost impossible to connect a 2wire DSL router with a Cable modem. They dont go hand in hand.
Although you can connect the outgoing ethernet wire from the modem in the last ethernet plug on the back of the router and then have the ethernet connections coming from the router. But not wireless. and if you find a way, contact me at jneal2k9@hotmail.com

Ps3


Are you going to connect your PS3 wired to your router or wireless?
1. check first if ps3 is working behind rca modem.
2. then connect a pc directly to your linksys router
3. open configuration page of linksys by typing your gateway on your browser. (usually it is by default 192.168.1.1)
4. go to applications and gaming tab
5. you'll find there port forwarding..key in your number there
> i guess your numbers are like 88 and 3764 (something like that)
6. if your trying to connect your playstation wirelessly, you need to know your wireless security (if your router is secured).
> go to wireless tab and look for wireless security
> get your key
7. go back to playstation and try to view your wireless network
> connect and type in your key
