Had same problem - said signal weak although strong on other devices, and hung on authenticating.

Getting an intermittent wireless connection can be attributed to the following factors:

a. 2.4 GHz wireless interference
b. Wireless settings of your router
c. Location of the devices
d. Obstacles

You may also refer to the common causes of interference:

Window in brick wall 2dB
Metal frame, glass wall into building 6dB
Office wall 6dB
Metal door in office wall 6dB
Cinder wall 4dB
Metal door in brick wall 12.4dB
Brick wall next to metal door 3dB

In order for us to isolate the problem, please refer to the steps below:

1. Avoid obstacles.

a. Try to move the router to different locations in order to get better connectivity. We suggest placing the router on high location to avoid obstacles that may be blocking the signal.

2. Reduce wireless interference in the area.

a. Try to move the router away from devices that are operating on 2.4 GHz frequency like your cordless phones and microwave ovens.
b. Try to move the router away from windows. Windows let in interference from the outside world.

3. Adjust the wireless settings on the router.

a. Please open any web browser like Internet Explorer or Netscape Navigator.
b. Connect to the router by typing http://routerlogin.com/basicsetting.htm or http://192.168.1.1 in the address field and click Enter or Return key.
c. For security reasons, the router has its own username and password. When prompted, enter admin for the Username and password for the Password, both in lower case letters.

Note: If it doesn't take password as the password, you might have changed it when you have run the NETGEAR Setup CD so please try other passwords. If you can't remember the password, you need to reset the router and run the Setup CD to reconfigure it.

d. Click on Wireless Settings under Setup tab.
e. Change the Network name or SSID to your preference.
f. Change the Mode to g and b only.
g. Change the Channel to 11, 1, 6 or 9.
h. Click on the Apply button.
i. Reconnect your computer to the wireless network and see if it fixes the problem.

Note: If the problem persists, you may need to upgrade the firmware of the router.

4. Upgrade the firmware.

a. Please verify the router version and model either underneath or at its side panel.
b. Go to http://kbserver.NETGEAR.com/downloads_support.asp and please select the model of the router.
c. Click the appropriate version of the router.
d. Select the link of the latest firmware. Click the button Right-click and Save to Download. Save the file to the Desktop.

Note: Please perform firmware upgrade with wired or Ethernet connection only. If your computer has wireless connection, then please disable it first.

e. Before upgrading, please write down all current settings since you need to enter them manually.
f. Using the computer hardwired on the router, please access the router’s setup page again by going to http://192.168.1.1 or http://www.routerlogin.com/basicsetting.htm
g. Click on Maintenance and then Router Upgrade.

You don't know the password to your wi-fi protected setup. They changed the password when they changed your equipment. Ensure you have the correct password and that you are not too far from the access point.

Authentication problem


Please clarify the d-link model number.

In setting up the phone and connection, you need to know a passphrase that was set up for the router. If you get that wrong, you have an authentication problem.

The PS3 browser doesn't work so well with that kind of stuff. You generally do all the authentication during the setup with your wirless router.
Try changing your password, using a different brand of routers, or simply change your security type like TSPK-WEP, or plain TSPK
