D-link dsl 2640u

When i power up My D-link dsl-2640u router the power led goes red for a while before the wlan and other leds goes green and then the power led goes green and back to normal. now i read on the manual that if the power led is red then there's a malfunction . is that an issue? .. another annoying one is that the status led goes off suddenly while the dsl/internet still green and this causes my internet to disconnect. how can i solve this? and is it a hardware or software issue?

It could be a hardware problem, try Resetting the D-link back to the factory defaults and configure the D-link again.
Press and hold the RESET button at the back of the router with the power ON until the LEDs flash at the time the release the RESET button. (firmware version was 3.00, and upgraded to 3.05)
Connect a LAN cable from the D-Link to your laptop computer's LAN port, open the browser on your laptop/computer and enter the D-Link's configuration URL..
http://192.168.0.1
The default login = admin
The default PW = blank (just press Enter)
You can now change the default admin password.
You can now configure the wireless settings. (SSID, WPA or WPA2 encryption to protect your wireless network and Internet from unauthorized access).
Now configure the wireless card in your computer laptop with the router's wireless settings.
To secure your wireless network from unauthorized access, please click on this link and follow my instructions :-

Reset router. There are two resets. A simple push reboots and holding it in clears all custom settings. Try the first.

This is a quick fix and usually does it. Test with network cable and work your way backwards to modem if you still have problems.

• Push and Connect (recommended). Either click the button or press the WPS
button on the rear panel of the Internet adapter.

INET light is on not able to connect to internet


Checked the instruction manual online. There's no INET light indicated. There's Power, Status, WAN, WLAN, and LAN LEDs. The WAN LED only indicates that the WAN port is connected to another device, e.g., cable or DSL modem. Check on your cable or DSL modem to see if the Internet light is on. If so, then you'll need to log into your router and go through the configuration/setup per the manual for your type of connection.

WHAT LIGHTS ON LINKSYS ARE SUPPOSED TO BE BLINKING


Note that incoming traffic will cause the WAN (or Internet) light to blink even if it is 'probe' traffic trying to break in to your network. Such traffic is to be expected and is the reason you have firewall functionality in your gateway router.

On the inside, there is a bit of traffic on any LAN when the computers are turned on. Messages generated by the router itself are used to find computers and printers for a lot of different legitimate reasons.

I want to change password on D-link DSL-2640U


Here is a direct link to show you how to secure your router, now you will need to reset your router to default settings before securing to do that press and hold the reset button located on the back of the router for 15 seconds or until router resets, you may need a paper clip to access the reset button.

No wireless connection for laptop. Linksys router - model #wrt160n v2


you can run a direct line to that router and go to the cisco web site and get the information you need to run that router. its a pdf format and is 2.56 Meg. Try this

SecureEasySetup (Orange/White) The Cisco logo is the Router's SecureEasySetup button. It

lights up and will stay orange when the Router is powered on. The color orange indicates that

the Router is not using the SecureEasySetup feature, while the color white indicates that the

Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup

mode, the Cisco logo will turn white and start flashing. After the Router has generated

the SSID and WPA Personal key, the Cisco logo will stop flashing and stay white.

To clear the SSID and WPA Personal key, press and hold down the Cisco logo for five seconds.

The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to

indicate a successful reset.NOTE: SecureEasySetup is a feature that makes

it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's

Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.

Power (Green) The Power LED lights up and will stay on while the Router is powered

on. When the Router goes through its selfdiagnostic mode during every boot-up, this

LED will flash. When the diagnostic is complete, the LED will be solidly lit.

DMZ (Green) The DMZ LED indicates when the DMZ function is being used. This LED will

remain lit as long as DMZ is enabled. WLAN (Green) The WLAN LED lights up when

the wireless feature is enabled. If the LED is flashing, the Router is actively sending or

receiving data over the network. 1, 2, 3, 4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port.

Internet (Green) The Internet LED lights up when there is a connection made through the

Internet port. A flashing LED indicates network activity over the Internet port.

Good luck

1st: Have you paid your bill?
2nd: Have you power cycled?
Full Power Cycle is as follows:

Turn off all components plugged into the router(Computers, Printers, etc.) Unplug the power from the router. Unplug the data cable(DSL, Coax) going TO the router. Wait aprox. 1 minute. Plug data cable and power cable back into router. Wait about 1 minute. Turn computers back on. Problem Solved?

If not and you're using DSL make sure all DSL filters are in place and that none have come undone. Make sure the phone line is still plugged in. Problem Solved?

If not contact your ISP and ask if they are doing any maintenance in your area that may by effecting your service. Ask them to perform a line test on you. If all else fails ask them to have a technician come out and help solve the issue.
