Question:

How can I fix the network adapter issue on my laptop after changing the router from my ISP?

I have a new router provided by my internet service provider (ISP), but it seems to have a different subnet mask than my previous one. My laptop’s network adapter shows that I have no internet access and no network connection, even though I can browse the web normally. What is the cause of this problem and how can I resolve it?

Answer:

If

you have recently changed your router from your internet service provider (ISP), you may encounter a network adapter issue on your laptop. This issue may manifest as a yellow triangle with an exclamation mark on your network icon, indicating that you have no internet access and no network connection. However, you may still be able to browse the web normally, which can be confusing and frustrating.

The cause of this problem is likely a mismatch between the subnet mask of your new router and the subnet mask of your laptop’s network adapter. A subnet mask is a number that defines how many bits of an IP address are used to identify the network and the host. For example, a common subnet mask is 255.255.255.0, which means that the first 24 bits of an IP address are used to identify the network, and the remaining 8 bits are used to identify the host.

When you change your router, your ISP may assign you a different subnet mask than your previous one. For example, your old router may have used 255.255.255.0, but your new router may use 255.255.254.0. This means that your new router can accommodate more hosts on the same network, but it also means that your laptop’s network adapter may not recognize the new subnet mask and think that it is on a different network.

To fix this issue, you need to update the subnet mask of your laptop’s network adapter to match the subnet mask of your new router. You can do this by following these steps:

– Open the

Control Panel on your laptop and click on Network and Internet

.

– Click on

Network and Sharing Center and then on Change adapter settings

.

– Right-click on the network adapter that you are using to connect to the internet and select

Properties

.

– Select Internet Protocol Version 4 (TCP/IPv4) and click on

Properties

.

– Click on

Use the following IP address

and enter the IP address, subnet mask, and default gateway that match your new router’s settings. You can find these settings by logging into your router’s web interface or by contacting your ISP.

– Click on

OK and then on Close

to save the changes.

• Restart your laptop and check if the network adapter issue is resolved.

If

you follow these steps, you should be able to fix the network adapter issue on your laptop after changing the router from your ISP. You should now see a green check mark on your network icon, indicating that you have internet access and network connection. You should also be able to browse the web without any problems.
