Reset Network Settings

| August 24, 2009 | 16 Comments

You can reset network settings if you are having problems getting connected to the Internet or to other computer’s on your LAN. A home or small office network consists of several important settings: the router, workgroup,┬áthe computer’s network adapter and the modem. If any of these are configured incorrectly you can no longer access Internet or local PCs. If your Internet worked but now it does not, you can try the following steps to regain connectivity.

Steps To Reset Network Settings

The following procedures will help you reset network settings on your computer:

Power Cycle Your Router

Power cycling your network is a technique used to attempt tho re-establish communication between the modem, the router and the PC. Usually, your ISP will provide your modem and router with an external IP address. The router then provides computer’s behind it with an internal IP address. Power-cycling the network will often renew IP addresses and get things working again. To do this, shut down your computer, unplug the router and then unplug the modem. Plug them back in, starting with the modem, then router. Give each a few minutes for all lights to go green, then power up the computer.

Make Sure the Network Adapter is Enabled

It is also possible to accidentally turn off your network adapter. This is especially true on laptops that have buttons or switches that allow you to disable your Wifi. To determine if your adapter is disabled, right-click My Computer, select Properties, then click the hardware tab. Under Device Manager look for your network adapter and confirm there is no red X over it. You can enable it again from the same place.

Check Your IP Address

To make sure you have an IP address local to your network, go to Start<Run and type cmd and hit OK. Type ipconfig /all and confirm you have an IP address similar to 192.168.1.2. If you have a 169.x.x.x IP address, then your computer is not getting an IP from the router, as it should. You can try right-clicking your network connection icon down by the clock and selecting “Repair” to see it that resolves the problem. If you have a wired connection, you can try a new cable.

You can also check to confirm your adapter is setup to automatically get an IP address from the router. To do so, go to the Control Panel, open Network Connections and then right-click your connection and select Properties. Highlight TCP/IP and choose properties again. Unless you have previously specified otherwise, make sure this is set to Automatic. If not set it to Obtain IP Address Automatically and reboot the computer.

Check the Router Settings To Reset Network Settings

Normally, the router should have an IP address just like your computer. It will have the aforementioned external IP address provided by your ISP and it will have what is know as a gateway address for your interior network. This is usually 192.168.1.1 or 192.168.0.1 depending on the manufacturer. Within the network setting administration, you will find an option for it to act as a DHCP server. Make sure this is enabled. You will also find a SSID setting. This should be named whatever your workgroup is to keep things simple.

In conclusion, there are multiple factors that can prevent Internet connectivity, so you must do a process of elimination. Ask yourself, is it strictly wireless? Are all computers having problems or just one? If I plug directly into the modem can I connect? By performing these troubleshooting steps to reset network settings, you should quickly be able to determine which component is causing the problem.

      If you reset the router, you’ll should probably unplug it, then unplug the cable model and then plug everything back in reverse order–cable modem, wait a couple minutes, then plug in the router.

      If this doesn’t fix it, you will probably need to login to the router and make sure it is setup as a DHCP server (which means it gives IP addresses to computers). If you need more help, join our free forums.

      Does the network adapter in the back of the PC where the network plug is connected have flashing lights? Make sure the device is not disabled in the Control Panel Device Manager.

    I’m trying to run other devices off my laptop currently and it used to be able to route my connection perfectly fine before. Is there any way I can reset my networking on my computer to make it so that the other devices can connect to the internet?

    Hi i have two the same ip on my network.. i cant play lan games. i have tl-mr3420 tplink router with dsl model. can anyone here help me to change the ip

    • Dave Dave says:

      Make sure all computers are set to Obtain IP Address Automatically. This is a setting under the TCI/IP properties of the network card. If that is set, reboot the computers and the router should give both machines a different IP address.

    Hi my problem is the following. I bought a netgeart N300 wireless router WNR200v2. I was able to install it and I was able to use my wifi fine with my iPhone and wii. Until I acciedenttly unplug power wired form the outlet that my router and modem when pluged into. When I plug it back to the power outlet and try to use my wifi on my iPhone I was able to receive the signal of my router but when I sign into it it lost connection to the Internet. So what I did was to re run the hard disk that my router came with to see if my router was the problem. And my laptop diagnose the problem and it said the wired that cone ts bothe of my divides was broken. So I unplug them and replug it just like the router manual said swiching the cabel that connects them and yet I have the same problem. I don’t know what to do, can you please help me.

    • Dave Dave says:

      There should be a reset on the back of the router. I would reset the router by depressing that button for twenty seconds and then run the setup just as you had the very first time.
