How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".

 

Unable to find USB Serial Port (Ports COM & LPT) in Device Manager Windows 11

After updating to Windows 11 I can no longer get the serial port in Ports COM & LPT from the Device Manager.

When I select Device Manager nothing shows up, I cannot see Ports COM & LPT.

These are the steps I have tried:

IN DEVICE MANAGER

• View: Show hidden devices in Device Manager (nothing happens)
  
• Scan for hardware changes
  
• Action: Add legacy hardware. Used both search recommended and add manually.
  
• When trying to add Communication Port: "Windows cannot determine the settings from this device". Does not work and have a yellow warning sign. When adding legacy hardware next time it is uninstalled since it says it does not work.
  
• When trying to add Serial Port: "The installation failed because a function driver was not specified for this device instance".
  

WINDOWS UPDATE

Making sure all updates are done (both software and hardware)

My system

• Windows 11
  
• HP Pavilion Laptop
