Question Connected to network but no internet (works on Ethernet and with other networks, other devices work on the WiFi too)

[mikeg1251]

I have a brand new laptop running windows 11. It connects to my home network via WiFi but says no internet. However, it’s able to connect with Ethernet. My other devices get internet with the same network WiFi. The laptop also was able to connect wirelessly to my hotspot with no problems.

Steps I’ve tried:
Changing DNS to 1.1.1.1
Manually entering IP address
Reinstalling WiFi driver
Resetting winsock
Restarting router and modem
Uninstalling stupid McAfee which was preinstalled (I still feel like this could be the culprit somewhere)

Any ideas for what I could try next?

change dns to 8.8.8.8

and disable ipv6?

Make and model modem?

Make and model router?

On the laptop in question run "ipconfig /all" (without quotes) via the Command Prompt.

You should be able to copy and paste the results without needing to retype everything.

Copy and past the full results. Redact any names that could be personally revealing.

What manual (static) IP address did you assign? What subnet mask was used?

Didn’t work unfortunately. Thanks for the reply.

I assigned 192.168.1.153 and subnet mask of 255.255.255.0

Sagemcom sax1v1s is the router. Haven’t had any other devices have trouble with it.

"ipconfig /all" results?

What info would be sensitive, just host name which is what I name the computer in case I used my real name? Is physical address for the LAN adapter’s sensitive? Pardon my ignorance on this.

I sent you a DM

Received your PM.

"ipconfig /all" is a basic troubleshooting tool.

The only concern being if the results reveal some personally identifying information.

Manufacturers are and have been reusing mac's. Spoofing is a very unlikely risk.

Here is my "ipconfig" where "X" represents what I would and do redact.

Not sure but the "ipconfig /all" results that you sent appear that there may be two wireless adapters enabled. At any given time there should only be one network adapter (be it wired or wireless) enabled.

Plus the IP address lease time is very short.

Based on what I noted within your "ipconfig /all" results I recommend:

- Disabling IPv6

- Increasing the lease time to at least a week.

- DNS Servers to be 8.8.8.8 and 8.8.4.4

- If Static IP addresses are being used/assigned ensure that any given static IP address is reserved for the intended device via that device's mac. And that that IP address is outside of the the router's allowed DHCP address range.

Duplicate IP addresses and/or macs can wreak havoc on a network.

I set IP back to automatic, disabled ipv6, and changed dns to the ones you have.

I did notice the system time wasn’t updated which affected the lease time being wrong, but fixing that and extending lease time didn’t fix the problem.

I’m just a bit confused as I’ve never seen this with any devices across any connections. Is it more common than I think and I’ve just gotten lucky?
