My dlink615 router connects,blinks and turns off many a times. tried reset option, firmware updation also failed through my router ip

The first step that we need to do here is to hard reset the router. At the back panel near the power, you can see the reset button... we need to press and hold it for about a minute..

(If the power light continuously blinking, we need to follow this step):
Step1: On the computer connected wired via the router, let's force card and set static IP on the computer.
(for windows XP)
> Go to control panel -- network connections -- right click local area connection and we can see properties. Click properties and let's go to configure. On that configure button, we now see advanced tab. Click advanced tab and choose link speed or duplex and value will be 10 MBPS half and click Ok.
> Right click again local area connection and click properties
> Highlight internet protocol tcp ip and go to properties. Once properties is open choose use the following IP address...
Please set IP to 192.168.1.5 / Subnet : 255.255.255.0 / Default gateway: 192.168.1.1
> After assigning the static IP please go to start - run - type cmd. On the blinking cursor type there ping(space)192.168.1.1 and press enter. If we are getting Request Timed Out, sad thing router is already defective. But if we are getting "Reply from...' then we need to update the firmware.


(After hard reset and router power light stays solid then we needs to reset up the router)

Check this tip out from Linksys. It is for a G VPN Router but you could use the same steps to troubleshoot. Title: Resolving Blinking Power or Diag LED on a Linksys Wireless-G VPN Router Article ID: 4982 If the Power LED on your Linksys router is blinking, this means the device is not ready. It should go off once the router completes its diagnostic test. If the Power LED won?t go off, it indicates that there?s a possible hardware problem with the router. To resolve this, you will need to perform five steps: Resetting the Router Assigning Static IP to the Computer Pinging the Router Accessing the Router?s Web-based Setup Page Updating the Router?s Firmware For instructions on how to reset the router, follow the steps below. Resetting the Router Hold in the RESET button at the back of the router for 30 seconds. Unplug the power to the router then plug it back in. If after resetting the router and the Power LED is still blinking, try resetting the router again for another 30 seconds. Then proceed with assigning a static IP address on the PC. For instructions, follow the steps below. Assigning a Static IP Address on Your Computer Most of the time, if the power LED on the router is blinking it loses its ability to assign IP addresses to the PCs connected to it, which is why you need to assign the computer a static IP address. After assigning a static IP address on the computer, check if the computer is still communicating to the router by performing a ping test. To ping the router, follow the steps below. Pinging the Router Ping test helps trace the communication between the computer and the router. The computer sends packets to the router and in return the router sends out replies to validate the connection. In this example, our router IP address is 192.168.1.1. NOTE: If you?re using Windows 98 or ME, click here. Windows 2000/XP Step 1: Click Start, then Run. Step 2: When the Run window opens, type ?cmd? in the Open field, then click OK. Step 3: When the MS DOS Prompt appears, type ?ping 192.168.1.1? and press [Enter]. Step 4: Check the ping statistics. You should get Packets: Sent =4, Received =4, Lost = 0 (0% loss). NOTE: If you?re not getting good replies from the router, it means the router is not communicating properly with the computer anymore. You can already consider the device defective. Windows 98/ME Step 1: Click Start, then Run. A window similar to Step 2 will appear. Step 2: When the Run window appears, type ?command? in the Open field, then click OK. Step 3: When the MS DOS Prompt appears, type ?ping 192.168.1.1? and press [Enter]. Step 4: Check the ping statistics. You should get Packets: Sent =4, Received =4, Lost = 0 (0% loss). NOTE: If you?re not getting good replies from the router, it means the router is not communicating properly with the computer anymore. You can already consider the device defective. If you get good responses from the router, access the router?s web-based setup page to see if a firmware update is possible. For instructions, follow the steps below. Accessing the Router?s Web-based Setup Page In order to perform a firmware update, you should be able to access the router?s web-based setup page. Updating the firmware is one way of resolving the blinking power light on the Linksys router. To access the router?s web-based setup page, click here. NOTE: If you?re having difficulties accessing the router?s web-based setup page, the router is considered defective. If you?re able to access the router?s web-based setup page, proceed in updating the firmware upgrade.

Linksys Red Diag or Power Light Blinking on the WRT54G

The above are instructions directly from Linksys.

Seems to be a common issue among these routers. If you tried to upgrade the firmware via wireless connection then it will generally fail. It is recommended to upgrade through the wired connection. In most cases if the upgrade failed and will not reset, most likely the firmware on the router has been damaged. Your best bet is to purchase a new router.

give the static ip address then you solve and update the firmware

Hi jsamanta!

First of all check if the power light is blinking or solid. if it's blinking reset your router.

When your computer is directly connected to the router try checking the IP address by clicking start>run> type cmd then ok. then type ipconfig then hit enter. IP address should be something like 192.168.1.100. not 169.254.xx.xx. if it's the latter reset your router. use a ball point pen or a paper clip. the reset button is a small hole at the back. If the IP address is like the first one i've mentioned. log-in to your router.

launch browser (internet explorer or firefox)
type http://192.168.1.1 or whatever your default gateway is. go to the status tab and check if you are getting a WAN or internet IP address. if not you will see a "release" and "renew" button. hit release then renew. if you're still not getting anything. do a power cycle. turn everything off. connect everything the way they are supposed to be connected. turn on modem first then router then computer.

If everything fails the last options is a firmware update on the router.


Hope this helps. =)

hello!

blinking power light after firmware upgrade sometimes indicates that the upgrade is not sucessful or the firmware that you load is incorrect.

-- try to reset the router for 30secs and check if the power light is still blinking
-- if its still blinking check your pc's ip address while connected to the router
-- if the ip address of your pc is invalid (169.x.x.x.) turn to manually assign static ip address to your computer and check if you can ping your routers ip address
-- if you can ping the routers ip address, upload the correct firmware to your router
-- if you cant ping your routers ip address still, reset the router again and try to ping the routers ip address once again
-- try to change port and cables
-- if still unable to ping the routers ip address, chances are that the router might be defective now

169 is an internal IP. If you are not already, try a hard wired connection to the router. If this fails, you will need to get in touch with D-link.
