FAQ

Cyberghost Accelerator provides detailed router configuration tutorials supporting popular firmware like Asus (Asuswrt-Merlin), Netgear, Linksys, OpenWrt, etc. The configuration steps typically include: 1) logging into the router management interface; 2) navigating to the acceleration client settings; 3) importing the configuration file provided by Cyberghost Accelerator; 4) entering your Cyberghost Accelerator account credentials. Once configured, all devices connecting to that router's WiFi will automatically receive accelerator protection without needing to install clients on each device separately.

Yes, Cyberghost Accelerator is specifically optimized for streaming performance. Our high-speed nodes can smoothly play 4K ultra HD video content. Cyberghost Accelerator regularly updates its server IP pool to ensure a stable streaming access experience. However, please note that Cyberghost Accelerator does not encourage users to violate the terms of service of any streaming platform.

Thanks to the efficient design of the WireGuard protocol, Cyberghost Accelerator has minimal impact on internet speed. In most cases, speed loss is under 5-10% of the original bandwidth. In some scenarios, if your ISP throttles certain types of traffic (like video streams or P2P), using Cyberghost Accelerator might actually improve your speed since the encrypted connection prevents your ISP from performing deep packet inspection (DPI) and traffic identification.

Yes, the Cyberghost Accelerator Lightning version supports up to 6 simultaneous connections, while the Premium version supports up to 10 devices. This means you can simultaneously use accelerator protection on your smartphone, computer, tablet, smart TV, and more, without incurring additional costs. If you need to protect more devices, it's recommended to configure Cyberghost Accelerator on your router to protect all devices in your household with a single setup.

Public Wi-Fi is a high-risk scenario for data theft by hackers. Once connected to Cyberghost Accelerator, all your internet traffic is transmitted through AES-256 encrypted connections, making it unreadable even if someone attempts a man-in-the-middle attack or sniffs the same Wi-Fi network. Cyberghost Accelerator also offers an auto-connect feature that automatically activates accelerator protection when an unsecured Wi-Fi network is detected.

Yes, Cyberghost Accelerator's zero-logs policy has been independently audited by the internationally recognized security auditing firm Cure53. The audit team thoroughly examined Cyberghost Accelerator's server infrastructure, codebase, and operational processes, confirming that Cyberghost Accelerator does not record any identifiable user data. The complete audit report is publicly available on the Cyberghost Accelerator website.

Yes, Cyberghost Accelerator provides a native command-line client for Linux, supporting major distributions like Ubuntu 18.04+, Debian 10+, Fedora 33+, CentOS 8+, and Arch Linux. Installation methods include one-click installation via APT/YUM repositories or manual installation using .deb or .rpm packages. The Linux client supports all core features, including the WireGuard protocol, split routing, and kill switch.

Yes, the Cyberghost Accelerator Premium version includes an exclusive static IP address. Static IPs are particularly useful for scenarios like remote access to corporate networks or NAS, running online services requiring a fixed IP, or avoiding captcha challenges triggered by frequent IP changes. The static IP is allocated for your exclusive use and is not shared with other users.

Cyberghost Accelerator incorporates comprehensive leak protection mechanisms: DNS leak protection ensures all DNS queries are resolved through encrypted connections; WebRTC leak protection prevents browsers from exposing your true IP via WebRTC interfaces; and IPv6 leak protection ensures that IPv6 traffic remains secure. You can validate your protection status at any time using the built-in leak testing tool in the Cyberghost Accelerator client or by visiting third-party detection websites.

Cyberghost Accelerator's proprietary obfuscation protocol disguises accelerator traffic as regular HTTPS traffic, effectively countering deep packet inspection (DPI) techniques. In environments with strict internet restrictions, the obfuscation mode of Cyberghost Accelerator can help users keep a stable connection to the free internet. However, please note that Cyberghost Accelerator advocates responsible accelerator use in compliance with local laws and regulations.

Cyberghost Accelerator supports multiple secure payment methods: Visa/Mastercard international credit and debit cards, PayPal, Alipay, WeChat Pay, and cryptocurrencies (Bitcoin, Ethereum, etc.). Choosing cryptocurrency payment can provide an extra layer of anonymity. All payment channels are processed through PCI DSS-compliant secure gateways, ensuring your payment information is safe.

Cyberghost Accelerator has deployed over 3000 servers across more than 80 countries and regions worldwide. Key coverage areas include North America (over 30 cities in the U.S. and 5 in Canada), Europe (25 countries including the U.K., Germany, France, the Netherlands, and Switzerland), Asia Pacific (15 countries including Japan, South Korea, Singapore, Australia, and India), South America (Brazil, Argentina, Chile, etc.), and the Middle East and Africa (UAE, South Africa, Turkey, etc.).

Yes, Cyberghost Accelerator provides browser extensions for Chrome and Firefox. The browser extensions run lightweight, encrypting only the traffic from the browser (without affecting other applications). They are particularly useful for quickly switching IP locations, such as for cross-border shopping comparisons. The browser extensions also include WebRTC leak protection and ad-blocking features.

Cyberghost Accelerator offers various customer service channels: 1) 24/7 live chat—visit the Cyberghost Accelerator website to chat with customer support in real-time, with an average response time of under 2 minutes; 2) email support—send an email to support@vpnjs.net, and you will generally receive a reply within 24 hours; 3) help center—containing hundreds of detailed tutorials and troubleshooting guides. Our support team provides bilingual service in Chinese and English.

Cyberghost Accelerator's Lightning and Premium versions come with built-in ad-blocking and malicious site protection. This feature operates at the DNS level, blocking the loading of ad trackers, malicious domains, and phishing sites during DNS resolution by maintaining a domain blacklist with over a million rules that is updated daily. This method is more efficient than traditional browser ad-blocking plugins because it prevents unnecessary connection requests at the network level.
