Why can't I browse the internet when I connect to Avast SecureLine VPN?

- Check the signal strength of your Wi-Fi. Some hotels or hotspots have weak Wi-Fi signals.

Why do certain websites claim that I'm connected to a different city than the city I selected as my VPN location?
Websites often attempt to identify the location of their visitors from their IP address, a process called IP geolocation. IP geolocation uses a database that pairs together IP address ranges and geographical information. The information in this database can be inaccurate for several reasons:
- Avast does its best to provide accurate information to the IP geolocation databases, but the database providers may take extra time to update the location.
- The website may be using an outdated version of the geolocation database.
- Some major websites (Google, for example) maintain their own databases based on what user traffic came from the IP address in the past.
- In certain locations we rent dedicated servers, and the IP geolocation databases are updated by the server provider on Avast's behalf. Because Avast is a Czech company, these providers may indicate the location as the Czech Republic. When this occurs, we work with the providers to update the information with the correct locations of our servers.
Why is my internet connection slower when I connect to Avast SecureLine VPN?
You may experience a slower internet connection when using Avast SecureLine VPN. This is because a VPN encrypts traffic and data before sending it to a server. Depending on the distance and capacity of the server, this process may cause a slightly slower, but safer, internet connection.
To troubleshoot this issue, refer to the following article:
