D-Link DI-614+ is causing Comcast Internet to boot wired user off internet every 45 minutes. It is also asking Iphone wireless user to put the password in every time Iphone user connects.Problems only recently started after years of easy use.

You'll need to access the administrator web page for your router, and then set a security key (password) for wireless users.

For step-by-step instructions for setting up security on the D-Link DI-614 router, see:

http://technicallyeasy.net/2010/10/how-to-secure-d-link-di-614-wireless-router/

log onto the router... put in address bar in Internet explorer 192.168.1.1 and put admin as the user and password or admin as the password. you should be able to see the passphrase and network keys under the wireless section.

how is your comcast connected to di-524?

make sure you have wireless enabled in router config. 
type in to your web browser 192.168.0.1 
login should be admin
password leave blank unless you have set one
then go to wireless section and check if it's enabled etc.

go to this link and read the manual.
You may require a firmware upgrade also.

Comcast is apparently weeding out multiple connections through routers. They want you to pay extra for their wireless router and pay an extra $5 a month too.

If you want to use your former router, you just have to connect the previous router in between your modem and computer. Try turning off all the devices (modem, router and computer) for 2 minutes. Then turn on the modem first, wait for the lights to be stable then turn on the router. When the router lights are okay that is the time that you can turn on the computer and check the internet connection.

If the Internet connection still has not come back, you will have to reconfigure it for Comcast connection. You can try using the setup CD or access the setup wizard using 192.168.0.1. User name is admin and leave the password empty then run the wizard.

You will net a cat5 network cable.

You need to do some reconfiguration on your router by using the setup cd or by manually configuring it using the user interface of the router.

You need to disable the DHCP server on your "slave" wireless router ( the di-524 ). In D-link routers this might be called configuring it to be an "Access point".

When this happens, connecting to the second wireless router should cause your computer to obtain an IP address which is in the range of the first router (that is to say, it will use the first router's dhcp server).

You should be able have your laptop connect with an automatic IP address and have it work.
