The IP address 127.0.0.1 is the loopback address which is used to establish a network connection to the same device. It shouldn't be the address assigned to your WiFi card, even with DHCP enabled.
Here are several possible solutions:
1. **Flush the DNS Cache and Reset IP**
Run the command prompt as administrator and type the following commands:
```
netsh int ip reset
ipconfig /flushdns
```
Then restart your computer. These commands will reset your IP settings and flush your DNS cache.
2. **Remove and Reinstall the WiFi Adapter**
This can be done through the Device Manager. Navigate to "Network adapters", find your WiFi card, right-click on it and select "Uninstall device". After the process is complete, click on "Action" > "Scan for hardware changes". Windows should automatically reinstall the driver.
3. **Update Network Drivers**
It could be a driver issue. Try updating your WiFi card drivers, either by going to the Device Manager and right-clicking on your WiFi card and selecting "Update driver", or by manually downloading the drivers from the manufacturer's website.
4. **Disable IPv6**
It is also possible that IPv6 is causing the problem. Disable IPv6 on the WiFi adapter by going to the properties of your WiFi card in Network Connections.
5. **Check for Conflicting Software**
Some software like VPNs can alter your network configuration. If you have recently installed any new network-related software, it could be causing the issue. Try to disable or uninstall it to see if the problem persists.
6. **Malware Check**
A malware infection could be redirecting your network traffic. Run an in-depth scan with a trusted anti-malware program.
7. **Check Router Configuration**
Although you mentioned that your Android phone is working perfectly on the same network, it's still worth checking your router's DHCP settings. There's a chance that some settings are configured in a way that they conflict with your laptop.
8. **Check with a New Network Profile**
Delete your current Wi-Fi network profile and create a new one.
If none of these steps resolve the issue, you might want to consider doing a clean install of your Windows OS or seek professional technical help. Remember to back up your data before reinstalling the OS.
