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 use TCP ports above 49728

Hello! I am an Independent Advisor, I would love to help you out!

The port range you are mentioning seems to correspond to the defaults for dynamic port range for windows 10. Which is probably why the issue just started and you can't bond to it. Windows probably dynamically changed the port range it was using at some point,
and it happened to overlap the ports you are trying to use.

You can view more about this here:

https://docs.microsoft.com/en-us/windows/client...

you can also check which ports are in you on your computer by opening a command prompt and running the following command:

netsh int ipv4 show dynamicport tcp

There is also a command listed in that article to change the defaults if needed.

Hope this helps!
