Cannot get a connection with the router installed. connection to internet works without the dlink .router works! Has been connected for 3 years

Do you have the Internet connected to the Internet port in the back of the DLINK? You will have to configure the DLINK for internet access. Open a web browser to your DLINK and check on the configuration under internet-setup. Select the type of internet connection you have i.e. DHCP, PPPoE, Static, etc. Once that is set up, you should have access to the internet like before.

the default dlink password is password or 1234
if that doesn't work then the password has been changed and you will need to reset the router to factory defaults. hold the reset button for 30 seconds while powered on.

Download and install the firmware update

Make sure to download the one for your specific model, and do the flash via a wired connection.
If no change, most likely a new router is in order

Make sure all the wires are connected properly. 1.-Unplug your modem and router from the power supply. Wait 1 minute. 2.-Plug your modem back to the power and wait for all the lights to stop flashing. 3.-Plug your router back to the power and wait for the lights to stop flashing
Follow these steps and your internet should be working again!

I was banging my head for 2 days with about 35 different configurations and finally tried the following and it worked just fine. Also, tried connecting 3 computers and they all connected with "NO" issues. Even connected wireless with "NO" issues. Now I am at 20mb download speed...J compared to AT&T 1.5mb download speed.

This is my DLINK model -> (DIR-601 Wireless N 150 Home Router Wireless router)

1. Reset your Comcast Surfboard Cable Modem by unplugging it for 5 minutes.

2. Then reset your DLINK Router to the manufactures default settings. Then Unplug DLINK Router for 1 minute then plug it back in (Just plug your cat5 cable into port 1 and connect it to your computer) there should not be anything else plugged into the DLINK Router at the time you make the changes. Just 1 computer can be connected.

3. Went into the DLINK configuration 192.168.0.1 and changed the PPPOE setting that I was using for my AT&T Modem to Dynamic IP (DHCP). Once you make the changes save them and then unplug your DLINK Router it's off.

4. Turn on Comcast Surfboard Cable Modem and wait until all lights are on. Now plug in a cat5 cable from the Surfboard Comcast modem (NOT A CROSSOVER CABLE LIKE THE CD INDICATES) to the INTERNET port of your DLINK Router. Now turn on your DLINK router.

5. Then turn on your computers or restart them and it will pick up IP Addresses from your DLINK Router

Have you tried resetting the router? Reset the router and see if that helps.

This is an intermittent wireless connection problem. If you have a cordless phone there, that's the main problem. If none, you need to change the wireless channel of your router to 11. You can do that by opening the router's admin page. If that didn't help, you need to update the router's firmware. Contact Dlink support for more details on how to update the router's firmware.

No need to install the dlink on the imac. All you need to do is connect the modem first the dlink. (Modem connected to Internet or WAN port of the dlink). Now if they are connected, your imac should be plugged in to port 1 of dlink, and your PC to port 2. That should do it.

Can you check if your laptop will still be able to get online if its in the same location where the non working wireless computer is?

for reseting the password of ur dlink router u have to press the rest button on the dlink router (genrallyit on the bottom or on the back of the router it is like a hole u have to use a pen or pin to reset the router back to its factory default settings after that password of the router will automatically back to admin or password login to ur router change the settings to static ip in the router so that u can provide the static ip of the other router to ur this router (example if primary router HL 2170 ip address is 192.168.1.1 then u will provide this dlink router the ip address as 192.168.1.5, subnet 255.255.255.0 default gateway 192.168.1.1 primary dns 192.168.1.1 now save the settings in the dlink router now the ethernet cable from ur other router will go directly in to the internetor wan port of this router. now connect wirelessly to any router both will work fine without any problem
