There are situations when a mobile hotspot created on your Android Phone works fine on other devices but on your Windows PC it says: Connected, No Internet.
Recently I encountered a similar situation on a fresh install of Windows 10 Version 1809. Before this I was running Windows 7 SP1 and though I occasionally encountered some connectivity issues of this kind, it had never persisted to the extent I was experiencing in Windows 10.
So what had changed? Nothing apart from the OS as I was still using the same Android phone and cellular network as before.
Troubleshooting Connected, No Internet Error
Running the Network troubleshooter didn’t help and only returned: the Wi-Fi doesn’t have a valid IP configuration Error.
A couple of thing suggested online that I tried to resolve the issue with include:
1. Reset your Wi-Fi adapter – this should be as simple as restarting your computer or replugging if you’re using an external USB Wi-Fi Adapter.
2. Release and renew your IP Address: run ipconfig /release in command line
3. Reset TCP/IP settings – run netsh int ip reset in command line then restart your computer
4. Reinstall your Wi-Fi Adapter Drivers
5. Change your DNS settings – this is what eventually worked for me
Solution: Change your DNS Settings
Windows by default uses the DNS configuration settings from your Internet Service Provider (ISP). In our case that would be the network carrier whose internet connection is used to create the portable Wi-Fi hotspot.
The ISPs are required to provide this service however you can override them with different DNS services that are more reliable, faster or that provide enhanced security.
Two commonly used alternative DNS services include the free Google Public DNS and Open DNS. Changing your configuration to use one of this or any other custom DNS servers will likely resolve this issue as it did for me.
To do this in Windows 10:
1. Right-click the Wi-Fi icon in the system tray and select Open Network & Internet Settings.
2. In the Settings window under the Change your network settings select Change adapter options.
3. In the Network Connections window identify your mobile hotspot connection then right-click it and select Properties.
4. In the Wi-Fi Properties window select Internet Protocol Version 4 (TCP/IPv4) then click the Properties button.
5. Now just choose Use the following DNS server addresses then enter your preferred DNS Servers addresses:
- Google DNS: 126.96.36.199 and 188.8.131.52
- Open DNS: 184.108.40.206 and 220.127.116.11
6. Click OK then close. Now just connect to the hotspot again and see if the problem has been resolved.
