I have followed instructions (several times) to connect my dlink router dir-615 and once I unplug the ethernet cable and attach to dlink (blue slot 1) and plug in power to the router....it no longer can access internet. service provider is comcast.

Upgrade to an ethernet cable connection between the router and the Roku. There is a slot on the side of the Roku box for it. This should enable you to enter the password- and give you a more stable streaming experience

Hi,
well here is a link to obtain the manual http://www.dlink.com/products/?pid=DIR-615
you need to select Support Resources Tab and choose the revision type you have. then you select product manual. One example is this one "DIR-615 no rev. http://www.dlink.com/products/?tab=3&pid=DIR-615&rev=DIR-615

If you have ethernet cable, plug one end of cable into in available slot of router (LAN) and other end ont your laptop to see if you can get out Internet that way. If not, turn off you router, wait for a minute and turn it back on. If it works after the reboot, try wireless again to see if it works. Most of time, router just needs to be rebooted.
thanks

How to secure the wireless network

You want to secure the wireless network.
Is there any computer connected to the router with the Ethernet cable?
If not then you will need to connect the computer to the router with the cable.
Check the IP address on the computer. Open the router set up page.
Once you open the set up page, you will find the option to make it secured

It appears your brother has changed your wireless router settings.
You can reset the Dlink back to the default settings by -
Power off the Dlink and press and hold the RESET button on the back of the Dlink and the power on the Dlink. Hold the RESET button for 5 secs. until the LEDs flash at the same time.
Connect a LAN cable from the computer to the Dlink. Open a browser and enter the Dlink's configuration URL
http://192.168.0.1
Default login = admin
PW = blank (just press Enter)
You can now change the admin password and set up a new passphrase (ie encryption)

You setup the router with the Ethernet cable always plugged in.. UNTIL you are finished configuring through the Ethernet cable via your browser. Once WiFi SSID & passwords WEP/WAP has been finished, AND you had another WiFi card in that PC the Ethernet cable was also connected to... well, THEN, I guess THEN, you may be able to disconnect the router from PC & then connect it again Wirelessly. But whats the point? But until then you won't find your router ON the Ethernet port, it would then be trough the WiFi adapter.. and that would have to be activated to work. Hope this clears things up

Use an Ethernet cable to connect the laptop to the router.
Access the router's built-in web-interface, and run the "Wireless Networking Setup Wizard", and choose a password.

Contrary to the many warnings not to install the router before starting the installation with the CD, I got the installation to complete only AFTER I installed the router inline thusly:

1. Power everything off.
2. Remove DI-604.
2. Install and connect 615 router to computer and to modem.
3. Apply power to router and modem.
4. Apply power to computer and wait until Windows loads.
5. Insert 615 installation CD.
6. Follow the directions.

Connect an Ethernet cable to one of the 'LAN' ports on the router and to the network-port on your computer.

Click Start
Click Run
Type CMD and press ENTER
Type IPCONFIG and press ENTER.

You should get output like:

Ethernet adapter Local Area Connection:
IP Address. . . . . . . . . . . . : 124.268.336.448
Default Gateway . . . . . . . . . : 123.456.789.0

Start Internet Explorer.
Type: http://123.456.789.0
to connect to the web-server "inside" the router.

Run the "wireless network setup wizard" to configure the router
with an SSID and a password.

Save and reboot the router.

Disconnect the Ethernet cable.

Your computer should report "Wireless Networks are available".
Choose your network, and enter the password for the network.
