Help with linksys router

there should be a hard reset button on there somewhere. Try that and go through the setup process again.

 

If it's new, you might call linksys for help. Or, your ISP helpline.

You can also reset your modem and the router at the same time to see if that has any effect.

Give us more details about your setup. What type of internet service do you have? ...type of modem?

 

I've had that happen with my WRT54 as well. Sometimes that will happen if your modem's internet connection is on DHCP. If it loses it's lease or the modem resets for whatever reason (power failure or low signal, or whim of your ISP), it will come back on with a different IP address and your router may not know the new IP. The typical recommended solution (by my ISP anyway) is to power down the computer, power down (unplug) the modem, and power down the router. Then reboot the computer, power up the modem and when the modem stops blinking, power up the router. Should be good to go with all three devices on the same page. You may also need to log onto the router and "Renew DHCP lease". Default setting for the router is 4 days IIRC.

edit:

Oops, I see you're on DSL, so you likely don't have DHCP. I'd try it anyway...

 

DSL has DHCP too.

Your modem may be locked onto the ethernet id of your iMac. Some modems will connect to a device, grab the ethernet ID and will only connect to that device. So if it has done that when connected to the iMac and then you connect it to the router, it will not talk to the router, only the iMac.

Pull the power from the modem for about a minute. Make sure you pull the power and not just turn it off (if it has a power switch). Turn the router off. Connect the modem to the router, power on the modem, wait for the modem to fully connect, and then plug in the router.

You should be good to go.
