FAQ
What sets Qifei Accelerator apart from other accelerators on the market?
Qifei Accelerator's main difference from traditional accelerators lies in its underlying protocol. Most accelerators still use IPsec or IKEv2, while Qifei Accelerator fully adopts the WireGuard protocol, which operates with only 4000 lines of code (IPsec exceeds 600,000), achieving 3-5 times faster transmission speeds while significantly reducing battery consumption. Additionally, Qifei Accelerator's no-logs policy has passed independent auditing by Cure53, and the audit report is fully transparent, demonstrating a balance between speed and security.
Which operating systems and devices does Qifei Accelerator support?
Qifei 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, Qifei Accelerator provides detailed router configuration tutorials, supporting mainstream router firmware like Asus, Netgear, and OpenWrt, allowing you to protect all connected devices with a single configuration.
What should I do if I am not satisfied with Qifei Accelerator and wish to request a refund?

What actual connection speeds can I expect from Qifei Accelerator?
Qifei Accelerator has deployed over 3000 high-speed server nodes globally, and actual testing has shown: average latency to Asia-Pacific nodes is under 30ms, around 80-120ms to North American nodes, with download speeds exceeding 500Mbps on gigabit broadband. Thanks to the efficiency of the WireGuard protocol, Qifei Accelerator maintains stable and smooth connections even in complex network environments.
What does Qifei Accelerator's no-logs policy entail?
Qifei Accelerator's no-logs policy covers all aspects: we do not record your original IP address, connection timestamps, websites or domains visited, DNS queries, or bandwidth usage data. All servers operate in a pure RAM environment, ensuring that data is automatically wiped upon physical reboot. This policy has been rigorously audited by the internationally recognized security audit firm Cure53, and the complete audit report is available on Qifei Accelerator's official website.
How do I configure Qifei Accelerator on my router?
Qifei Accelerator provides detailed router configuration tutorials that support major router firmware such as Asus (Asuswrt-Merlin), Netgear, Linksys, and OpenWrt. 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 Qifei Accelerator; 4) entering your Qifei Accelerator account credentials. Once configured, all devices connecting to that router's WiFi will automatically receive accelerator protection without the need to install clients on each device.
Can Qifei Accelerator be used to watch streaming content?
Yes, Qifei Accelerator is specifically optimized for streaming connection performance. Our high-speed nodes can smoothly play 4K Ultra HD video content. Qifei Accelerator regularly updates its server IP pool to ensure a stable streaming access experience. However, please note that Qifei Accelerator does not encourage users to violate any streaming platform's terms of service.
Will using Qifei Accelerator decrease my internet speed?
Thanks to the efficient design of the WireGuard protocol, the impact on internet speed from Qifei Accelerator is minimal. In most cases, speed loss does not exceed 5-10% of the original bandwidth. In some cases, if your ISP throttles specific traffic (such as video streaming or P2P), using Qifei Accelerator may actually improve your speed, as the encrypted connection prevents deep packet inspection (DPI) and traffic identification by the ISP.
Does Qifei Accelerator support simultaneous connections on multiple devices?
Yes, the Lightning version of Qifei Accelerator supports up to 6 simultaneous online connections, while the flagship version supports up to 10 devices. This means you can use accelerator protection on your phone, computer, tablet, smart TV, and more without extra charges. For protecting more devices, it's recommended to set up Qifei Accelerator on your router, ensuring all family devices are covered with a single configuration.
How does Qifei Accelerator protect my security on public WiFi?
Public WiFi is a high-risk environment for hackers to steal data. When connected to Qifei Accelerator, all your internet traffic is transmitted through an AES-256 encrypted connection, meaning even if someone is conducting a man-in-the-middle attack or sniffing on the same WiFi network, they cannot read your data. Qifei Accelerator also provides an automatic connection feature that activates accelerator protection when an insecure WiFi network is detected.
Is Qifei Accelerator's no-logs policy independently verified?
Yes, Qifei Accelerator's no-logs policy has been independently audited by the internationally recognized security auditing firm Cure53. The audit team thoroughly examined Qifei Accelerator's server infrastructure, codebase, and operational processes, confirming that Qifei Accelerator does not log any data that could identify users. The complete audit report is publicly available on Qifei Accelerator's official website.
Does Qifei Accelerator support Linux systems?
Yes, Qifei Accelerator provides a native Linux command-line client that supports major distributions like Ubuntu 18.04+, Debian 10+, Fedora 33+, CentOS 8+, and Arch Linux. Installation options include one-click installation via APT/YUM repositories as well as manual installation of .deb or .rpm packages. The Linux client supports all core features, including WireGuard protocol, split routing, and kill switch.
Does Qifei Accelerator provide static IP addresses?
Yes, the flagship version of Qifei Accelerator includes a dedicated static IP address. Static IPs are particularly useful for scenarios such as remote access to a company network or NAS, running online services that require a fixed IP, and avoiding captcha challenges triggered by frequent IP changes. Static IPs are assigned exclusively to you and are not shared with other users.
How can I ensure that Qifei Accelerator does not leak my IP address?
Qifei Accelerator comes equipped with comprehensive leak protection mechanisms: DNS leak protection ensures all DNS queries are resolved through encrypted connections; WebRTC leak protection prevents browsers from exposing real IPs via the WebRTC interface; and IPv6 leak protection guarantees IPv6 traffic is also safeguarded. You can use the built-in leak testing tool in the Qifei Accelerator client or visit third-party detection websites to verify your protection status.
Can Qifei Accelerator handle internet interference?
Qifei Accelerator's proprietary obfuscation protocol can disguise accelerator traffic as regular HTTPS traffic, effectively countering deep packet inspection (DPI) techniques. In more strictly controlled environments, Qifei Accelerator's obfuscation mode can help users handle restrictions and regain access to the free internet. However, please note that Qifei Accelerator advocates for the responsible use of acceleration services in compliance with local laws.
What payment methods does Qifei Accelerator accept?
Qifei Accelerator supports multiple secure payment methods: Visa/Mastercard international credit and debit cards, PayPal, Alipay, WeChat Pay, and cryptocurrencies (Bitcoin, Ethereum, etc.). Choosing cryptocurrency payments can provide additional anonymity. All payment channels are processed through PCI DSS compliant secure gateways to ensure the safety of your payment information.
In which regions does Qifei Accelerator have servers?
Qifei Accelerator has deployed over 3000 servers in more than 80 countries and regions globally.

Does Qifei Accelerator offer browser extensions?
Yes, Qifei Accelerator provides extensions for Chrome and Firefox browsers. These lightweight extensions operate only within the browser and encrypt traffic therein (without affecting other applications). They are particularly useful for rapidly switching IP locations, such as for cross-border shopping and price comparison. The extensions also include built-in WebRTC leak protection and ad-blocking capabilities.
How can I contact Qifei Accelerator's customer support team?
