How do I hook up the wireless router to my modem and tower? I ran the ethernet line from the back of the wireless router to the modem and the tower and my laptop said I as connected but the web page would not open up. I also could not use log on on my desktop.

is modem in bridge mode? sounds like you try wireless first. the router would then do the dhcp to get you on the net I would hook modem to router to tower. you may also want to power cycle them.

If you just bought the router, you will need to insert the router between your computer and your ATT DSL Modem. The cable from the wall goes into the modem (should already be that way) then the Ethernet cable from the modem should now go to the source of your Linksys Router. then use one of the ethernet ports from your router into the ethernet port on the back of your computer tower.

Use the documentation that came with the Linksys for more information on setting it up.

Good Luck

Is your modem a DSL or cable modem?
If it is a DSL modem do you have a DSL filter on each phone line to the phones in your house?
The DSL modem does not need a DSL filter on the phone line.

The single slot is where you connect your cable modem by use of ethernet (cat-5/6 cable). the other 4 act like a switch (basically plug your computer into those IF the router isn't a wireless router. IF it is, only use the single and only for the line coming from your cable modem.

First try connection the Yellow ethernet cable from the rca modem to your computer's network connection. If you get a connection this way, then your modem will work with a ethernet cable. If not, then call Comcast for help. The modem ethernet out to computer port must be connected to the wan line of the router. Then you can connect an ethernet cable from your computer network connection to one of the 4 ports of the router. For wireless connections you must set up the router and wireless adaptor with the same settings to connect. Follow the routers directions.
Good Luck

Once you have everything hooked up:
Ethernet cord going from modem into wireless router in port labelend internet or wan, and an ethernet cord going from the router to the xbox you should try these steps:

Unplug the power cord on the modem and plug it back in- once all the lights come back on
Unplug power cord on router and plug it back in-

Hope this helps.

Follow the dots -

2 wire DSL wire to back of DSL modem.

Ethernet cable out of DSL modem, to current router (if you have one).

Ethernet cable out of current router (if you have one) to new Wireless N router.

If you currently have a wireless G router, keep it, or, use the new Wireless G/N router alone. You will need to set up all security settings again if you remove your current router, and if the new router is N only, you will need to make sure all your wireless connecting computers have wireless N cards in them.

When you get cable internet, the cable company provides you with a modem (usually). From the cable modem you can hook up the Linksys router with an ethernet cable and it will work just fine. Hook the router up to the desktop or laptop with another ethernet cable if you need to make changes to the router security or whatever. The router address is generally 192.168.1.1. YOu can type that address right into the internet address and you router page shoud show up. If you have been using the Linksys router with the phone line all you need is to connect it to the cable modem to work. An ethernet cable is like a telephone line with a fatter connecter.

Plug your cable line into your modem, make sure it's tight, but don't use a tool. Next plug the ethernet line from the modem to your PC ethernet port. Then plug in your power to the modem. Allow your modem to sync. Don't use the USB line at all. Do not even hook it up unless your computer doesn't have a working ethernet line. Don't run the disk either, it will only install the modem driver that is only used if you use USB.

If you have issues connecting after that, you may have to go into your ethernet adapter settings and make sure that it is using DHCP. DSL usually uses a different setting (PPP I think) and you will not be able to connect.

By the way, excellent choice in modems.

Just plug the cable modem ethernet into the input to your router and you will be fine. Just remember, if you decide you want to make any changes to your router settings through your browser, make sure you hook up an ethernet line from your laptop to the router before making any changes. The reason for this is if you make a change in security settings on your router while wireless, the router will reboot and if your laptop did have the settings changed in it, you can be locked out.
Not that you can't get back in, but it is a pain to have to do.
