I switched my AT&T phone service to Comcast. I already have Comcast internet and TV
Comcast installed their modem.
The phone works ok. tv works ok.
I can work one computer directly from the modem.
When I try to connect the Linksys router, neither computer can connect to the internet.
The router worked ok with my old modem.
Please tell me how to make it work now.

Your Internet service provider is comcast cable company. You need to open the setup page of the router and change the Internet connection settings manually.
Connect the computer to the router and modem to the router. Open the setup page of the router using 192.168.1.1 Click on MAC address clone. Enable it and click save settings. Power cycle the router and your main computer will be online. Then you can change the wireless settings manually.
Most likely the router is not configured for dhcp or is not renewing to pull an address from your new provider. You will need to login to the router and check the WAN ip address settings. Choose dynamic ip address (it may be currently set for for static or another option based on your previous provider). Once you choose and save the settings, click to renew the WAN ip. If you were already set for DHCP and the address is correct, you may still have an issue with DNS,.. the DNS addresses may be incorrect or non existent. If you have doubts about DNS addresses,.. you may change them to 188.8.131.52 and 184.108.40.206 (opendns) and they will work with most providers (including comcast)
I hope this helps,.. if you need details,.. please leave a comment and I can supply more.
If you had your linksys router controlling the DSL connection, it was most likely a PPPoe connection requiring a username and password. Most cable companies have dynamic IP address and do not require a username or password.
Open your internet browser, IE, Firefox etc and go to 192.168.1.1 > Enter your router username and password, typically admin and admin
In the setup tab, change your connection FROM whatever is listed there and make sure it is Autumatic DHCP Save your settings, and restart the router.
Router setup Go to the control panel and un-install the program that the Comcast cd installed. then: Shutdown your PC. Unplug the power from the router and the cable modem. Wait 30 sec. then plug in the power to the cable modem, wait 30 sec. then plug the power to the router. Wait till you have "Internet" light then restart your PC. The PC should pick up an IP address and you should be able to get on-line. Did Comcast reset you wireless router settings? If so, you may need to set up your SSID and security settings.
Customizing Wireless Settings of the Router
Having default wireless settings on the Linksys router may cause conflict with other Linksys routers within your network range. Linksys suggests changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.
To change the router’s SSID or the wireless network’s name, click here. To change the router’s channel, click here. To enable the wireless security on the router, click here. If I could be of further assistance, let me know. If this helps or solves the issue, please rate it. Thanks, Joe
Ok, cable (coax) comes in from wall and attaches to modem. Ethernet cable goes from modem to WAN Port of router. You may have to reboot both devices to ensure that your modem (internet service provider) assigns IP address to your router. If PC is close enough, attach new ethernet cable from one of the 4 ports on your router down to your PC's ethernet adapter. (where your modem used to plug into). Router will now assign an IP address to your PC and you should be able to access the www.
Good Luck and let me know if you have any more questions.
