Usually when cisco equipment behave like that, its a problem with the power module, and it's best to contact the supplier...If it's under warranty they should replace it. If it's not you may need to get a technician to open it upand check the power module

Please try using Hyperterminal, it's in accessories> communications>
Use com port and click on "restore default" on next window and then ok. Then try typing it will probably work.
The console port is fine as you can see all the outputs coming from there.
Try changing the settings in putty under keyboard, make sure the bit rate selected is 9600bps.

If you can plug the cable that you have ran into your router into your computer directly and it works, then you can plug the router back in. Then connect the computer to the router via cable and unplug the router for about 15 seconds and plug it back in. If you connect the computer by cable directly and it doesn't work, then try unplugging your router for about 15 seconds and then plugging it in. I have found many networking items that need to be reset whenever a network cable is plugged in when the device is powered on.

Hi I heard about the problem of your not working router. Let me give you some hints that might solve your problem.
1. Verify wether your router is getting power.
2. Are there any new changes made to the configurations on the router? If so that might be the problem.
3. Is it giving you an error? If so how often does this error pops up?
4. Is it a repeatal problem or is it the first time you are encountering this problem?

Please take this up with your network administrator and please be honest when answering the questions he/she is asking you about the problematic router.

You can only reset password this way:
1.
Attach a terminal or PC with terminal emulation (for example, Hyper Terminal) to the console port of the switch.
Use the following terminal settings:
  • Bits per second (baud): 9600
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow Control: Xon/Xoff
2.Unplug the power cable.
3. Hold down the mode button located on the left side of the front panel, while you reconnect the power cable to the switch
4. Release the Mode button when the SYST LED blinks amber and then turns solid green. When you release the Mode button, the SYST LED blinks green.
5. switch: flash_init
6. switch: load_helper
7. switch: dir flash:
8. switch: rename flash:config.text flash:config.old
Rename config.text to config.old. In that file the password is stored.
9. switch: boot
10. Enter "n" at the prompt to abort the initial configuration dialog
11. Type en to enable
12. Switch#rename flash:config.old flash:config.text
13. Switch#copy flash:config.text system:running-config
14. Overwrite the current passwords:
conf term
enable secret <new pass>
enable password <new pass>
line vty 0 15
password <new pass>
login
line con 0
password <new pass>

15. write memory
16. copy run start
