FAQ
Everything you need to know about Qingfeng Accelerator
Qingfeng Accelerator differs from traditional accelerators primarily in its underlying protocol. Most accelerators still use IPsec or IKEv2, while Qingfeng Accelerator has fully adopted the WireGuard protocol, which requires only about 4000 lines of code (compared to over 600,000 lines for IPsec), resulting in a 3-5 fold increase in transmission speeds and significantly reduced battery consumption. Additionally, Qingfeng Accelerator’s no-logs policy has been independently audited by Cure53, with the audit report fully transparent, achieving a balance between speed and security.
Qingfeng Accelerator offers native clients for all platforms, supporting Windows 7 and above, macOS 10.14 and above, iOS 14 and above, Android 6.0 and above, and major Linux distributions (Ubuntu, Fedora, Debian, etc.). Additionally, Qingfeng Accelerator provides detailed router configuration guides that support popular router firmware, enabling protection across all connected devices after a single setup.
Qingfeng Accelerator offers a 30-day unconditional refund guarantee. If you are not satisfied with the service within 30 days of purchase, simply contact our customer support team via live chat or email at support@vpnjs.net, no reasons required, and you can request a full refund. Refunds are typically processed back to your payment account within 1-3 business days.
Qingfeng Accelerator has deployed over 3000 high-speed server nodes globally. Real test results show that the average latency for connections to Asia-Pacific nodes is below 30ms, while connections to North American nodes are around 80-120ms, with download speeds stably exceeding 500Mbps under gigabit broadband. Thanks to the efficiency of the WireGuard protocol, Qingfeng Accelerator maintains stable and smooth connections even in complex network environments.
Qingfeng Accelerator’s no-logs policy covers all of the following: no logging of your original IP address, no connection timestamp records, no records of visited websites or domains, no DNS queries, and no data regarding bandwidth usage. All servers operate in a pure RAM environment where data is automatically wiped upon physical reboot. This policy has passed a rigorous audit by the internationally recognized security audit firm Cure53, with the complete audit report available on the Qingfeng Accelerator website.
How do I configure Qingfeng Accelerator on my router?
Qingfeng Accelerator provides detailed router configuration tutorials, supporting mainstream router firmware like Asus (Asuswrt-Merlin), Netgear, Linksys, OpenWrt, etc. Configuration steps typically include: 1) Log into the router management interface; 2) Go to the acceleration client settings; 3) Import the configuration file provided by Qingfeng Accelerator; 4) Enter your Qingfeng 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 individually.
Can Qingfeng Accelerator be used to watch streaming content?
Yes, Qingfeng Accelerator has specially optimized streaming performance. Our high-speed nodes can smoothly play 4K ultra-high-definition video content. Qingfeng Accelerator regularly updates its server IP pool to ensure stable access to streaming services. However, please note that Qingfeng Accelerator does not encourage users to violate any streaming platform's terms of service.
Will using Qingfeng Accelerator slow down my internet speed?
Thanks to the efficient design of the WireGuard protocol, the impact of Qingfeng Accelerator on internet speed is minimal. In most cases, speed loss is less than 5-10% of the original bandwidth. In some situations, if your ISP throttles specific traffic (like video streaming or P2P), using Qingfeng Accelerator may actually improve your speed, as the encrypted connection prevents ISP deep packet inspection (DPI) and traffic identification.
Does Qingfeng Accelerator support simultaneous connections on multiple devices?
Yes, the Lightning Version of Qingfeng Accelerator supports up to 6 devices online simultaneously, while the Premium Version supports up to 10 devices. This means you can simultaneously use accelerator protection on devices like your phone, computer, tablet, smart TV, etc., without any extra charges. If you need to protect more devices, we recommend configuring Qingfeng Accelerator on a router for comprehensive protection across all family devices.
How does Qingfeng Accelerator protect my security on public WiFi?
Public WiFi presents a high-risk scenario for data theft by hackers. Once connected to Qingfeng Accelerator, all your internet traffic is transmitted through an AES-256 encrypted connection, making it impossible for anyone on the same WiFi network to read your data, even during man-in-the-middle attacks or sniffing attempts. Qingfeng Accelerator also provides an automatic connection feature that activates accelerator protection when unsafe WiFi networks are detected.
Has Qingfeng Accelerator’s no-logs policy been verified by a third party?
Yes, the no-logs policy of Qingfeng Accelerator has been independently audited by the internationally recognized security auditing firm Cure53. The audit team thoroughly examined Qingfeng Accelerator’s server infrastructure, codebase, and operational processes, confirming that Qingfeng Accelerator does not log any identifiable user data. The complete audit report is publicly available on the Qingfeng Accelerator website.
Does Qingfeng Accelerator support Linux systems?
Yes, Qingfeng Accelerator provides a native Linux command-line client, supporting major distributions including 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 of .deb or .rpm packages. The Linux client supports all core features, including WireGuard protocol, split routing, and kill switch.
Does Qingfeng Accelerator offer static IP addresses?
Yes, the Premium Version of Qingfeng Accelerator includes a dedicated static IP address. Static IPs are particularly useful for scenarios such as remote access to company networks or NAS, running online services that require a fixed IP, or avoiding verification challenges triggered by frequent IP changes. The static IP is allocated solely for your use and will not be shared with other users.
How can I ensure that Qingfeng Accelerator does not leak my IP address?
Qingfeng Accelerator has built-in comprehensive leak protection mechanisms: DNS leak protection ensures that all DNS queries are resolved through encrypted connections; WebRTC leak protection prevents the browser from exposing your real IP through the WebRTC interface; and IPv6 leak protection ensures that IPv6 traffic is also protected. You can use the built-in leak testing tool in the Qingfeng Accelerator client or visit third-party detection sites to verify your protection status.
Can Qingfeng Accelerator handle internet interference?
Qingfeng Accelerator's self-developed obfuscation protocol disguises accelerator traffic as regular HTTPS traffic, effectively countering deep packet inspection (DPI) technology. In environments with strict network restrictions, Qingfeng Accelerator’s obfuscation mode helps users keep a stable connection to the free internet. However, please note that Qingfeng Accelerator advocates responsible accelerator use in compliance with local laws and regulations.
What payment methods does Qingfeng Accelerator accept?
Qingfeng Accelerator supports various secure payment methods: Visa/Mastercard international credit and debit cards, PayPal, Alipay, WeChat Pay, and cryptocurrencies (Bitcoin, Ethereum, etc.). Choosing cryptocurrency payments offers additional anonymity. All payment channels are processed through PCI DSS-compliant secure gateways to ensure the safety of your payment information.
In which regions are Qingfeng Accelerator’s servers located?
Qingfeng Accelerator has deployed over 3000 servers across more than 80 countries and regions. Major coverage areas include North America (over 30 cities in the US and 5 cities in Canada), Europe (25 countries including the UK, Germany, France, Netherlands, Switzerland, etc.), Asia-Pacific (15 countries including Japan, South Korea, Singapore, Australia, India, etc.), South America (Brazil, Argentina, Chile, etc.), and the Middle East and Africa (UAE, South Africa, Turkey, etc.).
Does Qingfeng Accelerator offer browser extensions?
Yes, Qingfeng Accelerator provides browser extensions for Chrome and Firefox. The browser extensions run lightweight and only encrypt traffic within the browser (without affecting other applications). They are particularly suitable for scenarios requiring quick IP switching, such as cross-border shopping price comparisons. The browser extensions also include built-in WebRTC leak protection and ad-blocking features.

How does Qingfeng Accelerator’s ad-blocking feature work?
Qingfeng Accelerator’s Lightning Version and Premium Version come with built-in ad blocking and protection against malicious sites. This feature operates at the DNS level, preventing the loading of ad trackers, malware domains, and phishing websites by maintaining a domain blacklist containing over 1 million rules during the DNS resolution stage. This method is more efficient than traditional browser ad-blocking plugins, as it blocks unwanted connection requests at the network layer.
