FAQ

KeepSolid VPN Unlimited knowledge base

What is VPN?

VPN stands for Virtual Private Network. The main purpose of our VPN service is to ensure your security and privacy. To do this, KeepSolid VPN Unlimited encrypts the traffic you transmit over the network.

So how does VPN work?

KeepSolid VPN Unlimited adds a new network interface which functions exactly as if you are working with a direct internet connection. However, your IP address is different, and all your traffic is encrypted. VPN enables a host computer to send and receive data across shared or public networks as if they are an integral part of a private network; with all the functionality, security, and management policies that private networks provide.

Can I use your VPN instead of my current ISP connection?

Unfortunately, no. An internet connection and a VPN service are two different things. You need an existing and/or working (e.g. Cable, DSL, 3G, Satellite etc.) internet connection to be able to use KeepSolid VPN Unlimited.

What is the difference between a Proxy and a VPN service?

In essence, VPN connections are much more stable and secure than proxies. Not all applications are compatible with a proxy and most require a special configuration to work with one. You don't need any special set up for applications to work under a VPN connection.

Will KeepSolid VPN Unlimited slow down my system or internet connection?

We do not decrease the connection speed for any of our users for any reason. It doesn’t matter if you are a trial user or have purchased a subscription—we will provide you the highest and maximum possible connection speed for the current conditions. However, the setting for your connection may vary because of the current workload on the selected VPN server and the distance from you to the selected VPN server.

Can I increase the speed of my connection when using a VPN service?

This is possible as KeepSolid VPN Unlimited bypasses some of the throttles placed by ISP's.

How many servers do you have?

KeepSolid VPN Unlimited has 400+ high-speed servers across 70+ locations all over the world. The latest server list is available right in the application. We are constantly expanding our VPN solution server presence, so that you have the best and most reliable VPN connections. You can vote for the new server locations here: https://www.vpnunlimitedapp.com/en/info/specials/server-locations.

Does your app work in China?

We work day and night to provide you with the best service in any country; however, there are some technical limitations set by the Chinese government. We provide 5 VPN regions for our users in China: US, UK, DE, SG, HK. Also, for a stable VPN connection we recommend using the special KeepSolid Wise protocols. This option is available for iOS 10 or later, Android, Windows, macOS, and Linux devices. You can enable it at Account > Network Settings (for desktop computers), or at Settings > Protocols (for mobile devices).

Can I watch US Netflix, BBC iPlayer, and other streaming services abroad using KeepSolid VPN Unlimited?

Yes, you can. KeepSolid VPN Unlimited provides you with the possibility to stream the US Netflix, BBC iPlayer, HBO Now, ESPN+, Hulu, ITV, and many more content no matter where you find yourself. Simply choose the appropriate server and access any shows, movies, or documentaries you wish.

Does KeepSolid VPN Unlimited protect other protocols like Mail or FTP?

Once you are connected to our VPN server, all your programs use a virtual network interface which protects any app that accesses the internet from your device.

I received Google's "Suspicious sign in prevented" e-mail. Why is that?

When you have an active VPN, it acts as a relay—which means you surf the internet and use web services with the VPN server’s IP address instead of your own. Google permanently monitors your IP’s geographical location; if it changes dramatically, Google will send you a warning about suspicious activity. Read more about it here.

What is the Streaming region?

It is a set of servers that are optimized for watching video from such services such as YouTube, Vimeo, Dailymotion, US Netflix, BBC iPlayer, HBO Now, ESPN+, Hulu, ITV, and so on.

Why is my virtual IP detected to be from a different country than the one I choose?

Most of the geo-location services like WhatIsMyIP and SpeedTest rarely update their IP databases. That is why your virtual IP address can be detected as if it is located in a different country than the one you choose. To check out the location of our servers, please use the following link: http://www.neustar.biz/services/ip-intelligence. You need to input your virtual IP address in the appropriate field.

I'm running KeepSolid VPN Unlimited under Windows 8 and it can't connect to any server. How to fix it?

This is a known issue of the OpenVPN protocol, which is used for KeepSolid VPN Unlimited work. The fix is quite simple — just open the Network Center and the OpenVPN will start.

Navigate to the Desktop.
Right click the Network symbol in the taskbar.
Click Open Network and Sharing Center.

I already have another VPN software installed. Will it conflict with KeepSolid VPN Unlimited?

If you have installed another VPN software which also uses OpenVPN protocols and drivers, then you won't be able to run both apps simultaneously. So you will have to exit from one application before running another.
Note that some VPN applications remove OpenVPN drivers during the uninstallation process, so KeepSolid VPN Unlimited might stop working after you delete them. To fix this issue, simply reinstall the KeepSolid VPN Unlimited app again.

I'm trying to install the Windows version of KeepSolid VPN Unlimited and it doesn't work.

For this, we recommend you to temporarily stop any firewall or antivirus software on your Windows computer while installing KeepSolid VPN Unlimited. You also need to add KeepSolid VPN Unlimited to the exception list of your firewall software in order to allow it to connect to the internet. You can refer to our detailed manual on how to install KeepSolid VPN Unlimited on Windows..

The User Account Control (UAC) keeps asking me to allow the program to run. What should I do?

You may either lower the level (or disable) of the UAC on your computer or operate the computer as a Power User (Administrator). Please refer to our step-by-step manual on how to install KeepSolid VPN Unlimited on Windows.

The app doesn't run automatically after the MS Windows start. What should I do?

You need to allow KeepSolid VPN Unlimited to run after the startup. To do so, you might need to add it to the exceptions in your firewall or antivirus software.
For example, to add the app to the Windows Defender exception list, the next time Windows Defender alerts you about the software, on the Action menu in the Alert dialog box, click Always Allow. If you are prompted for an administrator password or confirmation, type the password or provide confirmation. Read more about adding an exception to Windows Firewall here.

What are the benefits of using a router with KeepSolid VPN Unlimited?

Using the router together with our VPN service gives you an opportunity to not only connect as many devices as you like, but also protecting them by preventing hackers from attacking, getting a wider access to web-restricted content, and maintaining strong online anonymity and privacy.

What do I need to use KeepSolid VPN Unlimited on a router?

Make sure that your router features VPN support (i.e. it should be with DD-WRT or Tomato firmware). Then create manual configuration files to make the router work with our service. In this regard, please follow a few simple steps described in our tutorial. Our networking experts have fully tested a good number of routers in and out by FlashRouters and pointed out the best ones to work with the KeepSolid VPN Unlimited service. Please see the list of recommended routers here.

How do DD-WRT and Tomato compare to the standard router firmware?

The standard router firmware gives you a limited control over the router, it is unreliable and often full of dangerous vulnerabilities that can put your entire online experience at risk. While DD-WRT and Tomato provide you advanced capabilities to make your network more controllable these are the most popular open-source router firmwares that transform a standard router with limited functionality into a powerful and multi-use one. The transformed router offers you a wide range of benefits; including superior network performance, the ability to encrypt your web-traffic through a VPN connection, and a whole lot more.

Can I upgrade my router firmware to DD-WRT or Tomato?

Possibly, these open-source firmwares are developed for specific router models. That is why your first step should be to find out if your device is supported. For DD-WRT supported devices, click here. For Tomato supported devices, click here

How to replace the firmware on my router?

The process of installing or replacing a firmware on a router is achieved by a method called flashing. In most cases, upgrading your router is almost as simple as installing a program to your computer. Yet, there is a huge difference. You cannot just uninstall a standard firmware and then install DD-WRT or Tomato. You must upgrade the router’s control panel first. If this is done improperly, your router’s hardware can be permanently damaged. For DD-WRT upgrade, please go here. For Tomato upgrade, please go here

What are the main differences between DD-WRT and Tomato?

To break it down, we have compiled a list of the most significant differences between DD-WRT and Tomato firmwares.
Please see the distinctive features for each firmware below and decide what fits you best.
Tomato firmware

Super-lightweight
Easier to install
More user-friendly interface
More consistent support and functionality with OpenVPN

DD-WRT firmware

A lot more supported devices
More supported functionality for wireless modes like Repeater Bridge
More built-in options for more advanced features like WI-Fi hotspots
Supports OpenVPN and PPTP protocols

General: I’m getting low connection speed with VPN. What do to?

We provide the maximum possible connection speed for the current conditions. However, the conditions for your connection may vary because of the current workload on the selected VPN server and the distance from you to the selected VPN server. Also, there is always a chance of slowdown because of your ISP throttling VPN protocols. We cannot control these circumstances.

So, as a suggestion, try to connect to a several servers that are geographically closer to you, and check the performance.

Also, if you've enabled KeepSolid Wise, it might decrease the speed. Please, try to switch to a different VPN protocol in the Settings of the KeepSolid VPN Unlimited app, and check the performance again.
