In Linux it's the same steps just a little easier.In your taskbar click the network icon, click edit or new if you want several IP's, add the numbers and you're done!

In Windows open "Change adapter settings"

If you don't know how to get to "Change adapter settings" open Control Panel (View by: Large icons).
Left click "Network and Sharing Center"


Left click "Change adapter settings"


Now look for your ACTIVE connection. It can be a VPN, WIRED or WIRELESS connection.
Then right click and left click "Status"


Now left click "Details" 


You should see your default DHCP settings. If you haven't changed the DHCP settings DHCP Enabled will say YES
Your IPv4 Default Gateway is the INTERNAL IP address of your router. And your starting IP address.
The number can be anything 192.168.1.1 is the most common, some are 10.0.0.1.
If your IPv4 DNS Servers are the same as your Default Gateway you will need to find your ISP's DNS servers or use new free/open servers. If your IPv4 DNS Servers are different then your Default Gateway IP. Then take a screen shot or writhe those down.
Moving forward write down the Default Gateway and the DNS Servers.
Left click Close.


Now left click "Properties".


Left click and highlight "Internet Protocol Version 4 (TCP/IPv4)
(IPv6 should be unchecked, disabled unless you like getting hacked)
Then left click "Properties"


Now select "Use the following IP address"
Write in the number it should be something higher then your Default Gateway.
So if your default gateway was 192.168.1.1 you can use 192.168.1.2 to 192.168.1.130.
10.0.0.2 to 10.0.0.130, 192.168.0.2 to 192.168.0.130 and so on.
What ever the last number in the default gateway was just make yours higher.
The Subnet mask will always be 255.255.255.0 unless someone has forced a different one.
Default Gateway that will be the IP address you wrote down or took a screen shot of under "Status"
Preferred DNS server: Should be either a free one or one from your ISP I use OPEN DNS because they are faster.
Alternate DNS server: SAME AS ABOVE


Then left click OK you will get disconnected for a few seconds then your internet should be back up and working. The reasons you may want to do this? LOL
Well you're using Winblows 10 and it keeps resetting all your numbers to 0.0.0.0.
You're using Winblows 10 and can't open any websites but you can ping websites from dos.
You want to setup port forwarding for sync software, games, host your own website, you need to set a static IP on your printer...

OK here is a great little tool for finding the fastest DNS servers for you. Download the tool, run it look at the DNS servers. Be careful NOT to use google DNS servers as they collect and KEEP everything you do online!

Hi Josh,
First are you using Windows?
Which version?
Did you write in http://192.168.1.1 or 192.168.1.1?  http://192.168.1.1 should work.
Is 192.168.1.1 listed as your IPv4 Default Gateway under "Network Connection Details".
How old is that router? That model says 2010? If you have had that router more then 5 years I would replace it.


Different routers can use different numbers.
I looked up your router these are the default settings:
Open your browser type or copy & paste http://192.168.1.1 into browser address bar. Chromium (not google chrome), Brave, Firefox, Slimjet, new Edge Chromium.
Username: admin
Pasword: admin
These are all the IP adresses TP-link Routers use:
192.168.1.1
192.168.0.1
192.168.0.25
192.168.1.25
192.168.100.1

If none of those work you need to reset you router.

Toreset that router one of these should work.
With the RESET/WPS button
Have the unit powered on
Press and hold the reset (sometimes reset/WPS) button for 10 seconds with a paperclip or other sharp object.
When the SYS led start blinking quickly release the reset button and wait for router to boot back up.

The 30-30-30 reset
If the above instructions don't work you can always try the 30-30-30 reset as follows:
When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp)
While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds
While still holding the reset button down, turn on the power to the unit again and hold for another 30 seconds.

Let me know if you got it?
