Windows 10: Need help with tranferring settings to new router

I volunteer for Habitat for Humanity. I have little networking knowledge, but still it is the best they have on site. They have a TP Link N750 router on their network which is failing and needs to be replaced. It will be replaced with a Linksys AC1900 router. I have transferred all the wifi and sign on settings, but I may need help with device specific IP settings (I think).

Background- I tried this before by simply replacing the old router with another router. Everything worked as it should except the Point of Sale (POS) computer. It could not connect to its server which is also on the LAN. I assumed the reason for this could be in some router settings specific to those computers such as a static IP or reserved IP address.

Currently- I got the MAC address for each of the POS and server. Now as I look at any device list on the old router I cannot find these MAC addresses at all.

Please tell me what I am missing.

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".

 

DNS problems with router

A couple suggestions I have for you:

Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

Last option, is look for a new router.
