Internet connection problems

Unplugging the power lead for 20 seconds or so and then plugging it back in and turning on?

That is always the first thing to try after a Power Outage as when it comes back on there are spikes which screw up the Modem.

Connect your computer directly to your modem – bypass your router – if this helps, then your router is causing issues with your VPN account as sometimes router settings can affect your VPN. Check your firewall software and test if it's conflicting with your VPN. Disable and try connecting again.

Hey
If your VPN client isn't connecting, try starting a website without connecting through a VPN to see if your internet connection is working. If your internet is still down, it may be a query at your ISP's end. Preview your VPN provider's website, too, to make sure that the server you're trying to connect to isn't down.

You will have to troubleshoot to see where's the underlying problem.

I would open the command prompt and run the ping command to test the internet connection. If it shows 0 percent loss that means your connection is fine. 100 percent loss means your internet is down. At this point, I'll restart the router from the admin portal and reconnect. If it's still down I'll contact the ISP.

I personally use DewVPN. You may try it and see if issue will still persists. Just give it a try, it's free. Here you go - www.dewvpn.com
