This is caused by the firmware not loading correctly. Follow the steps below to fix this. 1. You will need to gain Internet access to download the latest firmware for your router. The firmware must be present on the computer that will do the upgrade. Temporarily bypass the router and plug directly into your Internet Service Provider?s modem to gain access, or use another location other than your own to get to the Internet and download the firmware. 2. Download the latest firmware for your Router from Select the model number of the Linksys router you have. Be sure to select the correct router version (BEFSR41 V3), as firmware upgrades vary by version. 3. Click the ?Get Upgrade? button. 4. After the firmware page opens, click the link that says, ?Click here to download the latest firmware...? and download the firmware file. Once you download the Zip file, unzip it and extract all files. If you do not have an unzipping program, go to and download WinZip, which will allow you to unzip the file. Before performing the upgrade, assign your computer a static IP address. For more information, please see Answer ID 534 for instructions. If using a 10/100-network adapter, change its speed to 10Mb, half duplex. For instructions on doing so: Windows 95/98/ME 1. At the Windows desktop, click on Start then choose Settings and click on Control Panel. 2. Double click the Network icon. This will bring up the ?Network Configuration? window. 3. Locate and highlight the icon with the green logo for your network adapter and click Properties. 4. This will display the network adapter's Properties. 5. Select the Advanced tab and click Connection Type (this may also appear as Media Type, Connection Speed, Mode, Link Speed, etc). The current default value should be set to "Auto sense" or "Auto". 6. Change the value of this option to 10Base-t, half duplex mode (usually the lowest possible option). The wording of this value may also vary, depending upon the make and model of the Network Adapter. Other possibilities include 10T half, 10Mb half duplex, 10Mbps half, etc. 7. Once this has been changed, click OK to return to the Network configuration screen. 8. Click OK again and Windows will ask to restart your computer. Click ?Yes? to restart. Windows 2000/XP 1. Go to Start click on Run and type in control ncpa.cpl. 2. Double click on the Local Area Connection that controls your network card. 3. Click Properties under Local Area connection status. 4. Click the Configure button. Then, click on the Advanced Tab. 5. Click Connection Type (this may also appear as Media Type, Connection Speed, Mode, Link Speed, etc). The current default value should be set to "Auto sense" or "Auto". 6. Change the value of this option to 10Base-t, half duplex mode (usually the lowest possible option). The wording of this value may also vary, depending upon the make and model of the Network Adapter. Other possibilities include 10T half, 10Mb half duplex, 10Mbps half, etc. 7. Click OK after you made the change then click Close. Reloading the firmware 1. First, hold the reset button located on the back of the router for 30 seconds. 2. Next, to test communication between the Router and the network card: Go to Start, and select Run. Type in command and press [Enter ]. This will bring up the MS-DOS prompt window. 3. Type ping and press [Enter ]. 4. You should get the following results: Pinging with 32 bytes of data: Reply from bytes=32 time<10ms TTL=128 Reply from bytes=32 time<10ms TTL=128 Reply from bytes=32 time<10ms TTL=128 Reply from bytes=32 time<10ms TTL= 128 5. Once you get these replies, close out of the command prompt by typing in exit and pressing [Enter ]. 6. You may now proceed to upgrade the router?s firmware with the files that were downloaded. 7. Once the upgrade is complete, the router's Power light should no longer be blinking. Note: Be sure to go back to your network card settings (from the steps above) and change the speed of the link back to ?Auto sense? or ?Auto? (the original default setting) to restore full speed to the adapter. If any of the steps do not work, or if you are having other difficulties, please contact Linksys Technical Support for further assistance.

When I turn on my BEFSR41 the POWER and PORT #4 lights up even though nothing is connected to it yet... what seems to be the problem?... is it defective?

If you are using the Uplink port, this may cause port 4 to show active. Disconnect the Uplink cable to see if the light goes out. If it doesn't, then yes, it sounds like you may have a bad port on your router.

If the power light keeps blinking it means that the router has reached its end point or else you have short circuited the board, or the router is reached up to the maximum whereby it has totally failed. The best would be to replace that router now or try to use a software named tftp to get into the router interface if it is possible then upgrade the firmware/ You can get tftp by searching in google.
