Cannot obtain internet through router

Power off Cable Modem, PC, router, and then disconnected them. Directly connected Cable Modem with PC (Don't connect the router) and power on Cable Modem. When Cable Modem is ready with LED lamps under normal status, also power on PC and try to access Internet service. If Internet service is resumed, please study the router setting of Cable Modem which referred to router's user manual.

The ISP modem connects to the main LAN port on the router. The PC connects to any other port. Done. You should have internet via wire at this point.

update the router firmware
You can do it via Linksys or as many of us have done, use this 3rd party firmware

You need to check first if the internet is working if you connect your computer directly to the modem. If there is internet on your modem, you need to reset and reconfigure the router. If there is no internet on the modem, you need to contact your internet provider.

You have two ways on how you can get other computer online through this router. First, you can wired them (using an Ethernet cable) to one of the Ethernet ports on the back of the router. They are the ones labeled 1, 2, 3, and 4.

Second is through wireless, but those computers that will connect through wireless must also have a wireless adapter to be able to pick up the signal that this router is broadcasting.

Isolate the issue by directly connecting the PC to the router via ethernet cable (if possible).

If you were able to get online while hardwired connected to the router, then check the IP address of the wireless network connection, check the wireless security if the network key matches.

If you cannot get online while hardwired to the router, then directly connect the computer to the modem.

If you were able to get online while directly connected to the modem, then the problem is the internet settings on the router. Check the WAN configuration, such as DHCP or PPPoE.

If you cannot get online when directly connected to the modem, then you will need to contact your Internet Service Provider.

It seems that your cabling is wrong. This is what it should look like:

1. Telephone outlet to cable modem (Via telephone cable)
   
2. Cable modem to router (via Ethernet cable)
   
3. router via Ethernet cable or wireless to computers

Does your setup look like this? Please let me know if not so we can configure it correctly.

you could try getting a wifi adapter and creating an access point, you can connect that way if your ps3 has wifi I have a laptop with windows XP Pro and have been trying that my desktop PC with Vista Home can see it.

You have to check if your computer can connect to the modem with an Ethernet cable. This will tell you if the ethernet port on the modem is working. if that does not work call your cable provider.

Next thing after you get the instructions above done.

Press the reset button on the back of the router> press it in for 30 seconds then let go and pull out the power. Connect the router up the way it should be before you reset by the way. check if you have internet if you do not follow hte directions at teh link below.

CABLE SETUP

If you need more info just message me

I may be able to help with this...but I need a detailed description of how you have things connected between the XP desktop, the cable, modem, the Linksys router, and the laptop. Also, is the Linksys router new?

Typically, the wan port on the wireless router connects directly to the cable modem with a cat5 network cable....then the desktop pc connects to the router...on port 1 for example...with a similar cable. Once the wireless router is set up properly, the laptop should then be able to connect using wireless.
