Wep to wap. i want to do a hard reset

Connections All Ethernet Ports (WAN and LAN) are auto MDI/MDIX, meaning you can use either a straight-through or a crossover Ethernet cable. Pressing the Reset Button restores the router to its original factory default settings. Auto MDI/MDIX LAN ports automatically sense the cable type when connecting to Ethernet-enabled computers. The Auto MDI/ MDIX WAN port is the connection for the Ethernet cable to the Cable or DSL modem Receptor for the Power Adapter 5

Gen. will not go back to utility after gen run.

Hi and welcome to FixYa. I am Kelly.

This is usually caused by a problem in the utility service sense coils or wiring. The biggest factor causing sense coil problems is the positioning of the wires to be sensed or.... corrosion on the terminal blocks that mate the sense coil wires to the extended controller wires. You can read out the sense coil(s) by disconnecting ONE wire at the terminal strip and reading resistance. You have to do this with each sense coil. (Disconnect one wire to read resistance.) All sense coils must read within 25 ohms of the rest of the sense coils.

There is a possibility of the contactor relay(s) sticking but these are energized in both directions. Should there be a contactor sticking problem they make a very loud buzz vs cycling normally.

Form what I am reading you get auto switching to stand-by power when utility power is lost but no auto-switching back to utility power when utility power is restored.

Check for corrosion on the terminal boards... and on the main board printed circuit card. IF you have to do any cleaning use a Q-tip and 100% isoprophyl alcohol. DO NOT use contact cleaner as it will destroy the conformal coating on your controller PCB. Wait 30 mins after use of the alcohol for the alcohol and condensation to evaporate before energizing circuits.

Thanks for choosing FixYa,

Need a new adapter for my 620 laptop.. immediately. any ideas what I can purchase to get me going tomorrow?

I'm not sure exactly what "620" laptop you have, and exactly what "adapter" you're looking for, so I'll assume it's a power adapter. If it's one of the major manufacturers like Dell, Acer, HP, Gateway, etc... you should be able to find a universal power adapter from places like Best Buy or Radio Shack. I know they both normally carry a universal power supply for laptops. It's auto-voltage-sensing and comes with a bag of inter-changeable power connectors to fit most laptop models. I've seen these made by Belkin, iGo (Radio Shack), and Targus.

I have had problems finding a power cord that works. The original cord died and replacements give eroors

If you are not using a Dell Branded power cord, the system will give an error due to non-Dell AC adapters do not have the sensing circuit needed for the system to ID the adapter.
If you are using Dell Branded replacement AC adapters, then you most likely have a bad power connector on the motherboard.

Power light flashing/blinking on the BEFSR41 V3

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.
