FAQ
Everything you need to know about 91 Accelerator
What fundamentally sets 91 Accelerator apart from other accelerators on the market?
91 Accelerator's main difference from traditional accelerators lies in its underlying protocol. Most accelerators still use IPsec or IKEv2, while 91 Accelerator fully embraces the WireGuard protocol, which has only 4000 lines of code (compared to over 600,000 lines for IPsec), providing a 3-5 times speed increase while significantly reducing battery consumption. Furthermore, 91 Accelerator's no-logs policy has been audited by Cure53, with the audit report publicly available, proving that it achieves both speed and security.
What operating systems and devices does 91 Accelerator support?
91 Accelerator offers native clients across all platforms, supporting Windows 7 and above, macOS 10.14 and above, iOS 14 and above, Android 6.0 and above, as well as major Linux distributions (Ubuntu, Fedora, Debian, etc.). Additionally, 91 Accelerator provides detailed router configuration tutorials, supporting popular router firmwares like Asus, Netgear, and OpenWrt, allowing you to protect all connected devices in your home with a single setup.
How do I get a refund if I'm not satisfied with 91 Accelerator?
91 Accelerator offers a 30-day unconditional money-back guarantee. Within 30 days of purchase, if you are dissatisfied with the service, simply contact our support team via live chat or email at support@vpnjs.net without providing any reason, and you can apply for a full refund. Refunds are usually processed back to your payment account within 1-3 business days.
What is the actual connection speed I can expect with 91 Accelerator?
91 Accelerator has deployed over 3000 high-speed server nodes globally, and actual testing shows that: the average latency to Asia-Pacific nodes is below 30ms, while latency to North American nodes ranges from 80-120ms, with download speeds stably reaching over 500Mbps on gigabit broadband. Thanks to the efficiency of the WireGuard protocol, 91 Accelerator maintains stable and smooth connections even in complex network environments.
What does 91 Accelerator's no-logs policy specifically cover?
91 Accelerator's no-logs policy includes the following aspects: we do not record your original IP address, connection timestamps, websites or domain names accessed, DNS queries, or traffic bandwidth usage data. All servers operate in a pure RAM environment, automatically clearing data upon physical reboot. This policy has been rigorously reviewed by the internationally recognized security auditing firm Cure53, and the complete audit report is available on the 91 Accelerator website.
91 Accelerator provides detailed router configuration tutorials, supporting mainstream router firmwares such as Asus (Asuswrt-Merlin), Netgear, Linksys, and OpenWrt. Configuration steps typically include: 1) logging into the router management interface; 2) entering acceleration client settings; 3) importing the configuration files provided by 91 Accelerator; 4) entering your 91 Accelerator account credentials. Once configured, all devices connected to that router's WiFi will automatically gain accelerator protection without the need to install clients on each device.
Yes, 91 Accelerator is specifically optimized for streaming performance. Our high-speed nodes can stream 4K ultra HD video content smoothly. 91 Accelerator regularly updates its server IP pool to ensure a stable streaming access experience. However, please note that 91 Accelerator does not encourage users to violate the terms of service of any streaming platform.
Thanks to the efficient design of the WireGuard protocol, 91 Accelerator has minimal impact on internet speeds. In most cases, speed loss is no more than 5-10% of the original bandwidth. In some instances, if your ISP throttles certain types of traffic (like video streaming or P2P), using 91 Accelerator may actually improve your speeds because the encrypted connection prevents the ISP from performing deep packet inspection (DPI) and traffic identification.
Yes, the Lightning version of 91 Accelerator supports up to 6 simultaneous connections, and the Flagship version allows for up to 10 devices. This means you can use accelerator protection across your smartphone, computer, tablet, smart TV, and more without any extra fees. For additional device protection, it is recommended to set up 91 Accelerator on your router, safeguarding all devices in your household with a single configuration.
Public WiFi is a high-risk environment for data theft by hackers. Once connected to 91 Accelerator, all your internet traffic is transmitted through an AES-256 encrypted connection, rendering your data unreadable even if someone conducts middle-man attacks or sniffing on the same WiFi network. 91 Accelerator also features an automatic connection function: when an insecure WiFi network is detected, accelerator protection is automatically activated.
Yes, 91 Accelerator's no-logs policy has been independently audited by the internationally recognized security auditing firm Cure53. The audit team conducted a thorough examination of 91 Accelerator's server infrastructure, codebase, and operational processes, confirming that 91 Accelerator does not record any data that could identify users. The full audit report is publicly accessible on the 91 Accelerator website.
Yes, 91 Accelerator provides a native command-line client for Linux, supporting popular distributions like Ubuntu 18.04+, Debian 10+, Fedora 33+, CentOS 8+, and Arch Linux. Installation options include one-click installations through APT/YUM repositories or manual installations of .deb or .rpm packages. The Linux client supports all core features including the WireGuard protocol, split routing, and the Kill Switch.
Yes, the Flagship version of 91 Accelerator includes a dedicated static IP address. Static IP addresses are particularly useful for scenarios such as remote access to company networks or NAS, running services that require a fixed IP, or avoiding CAPTCHA challenges triggered by frequent IP changes. The static IP is assigned exclusively for your use and is not shared with other users.
91 Accelerator has comprehensive leak protection mechanisms in place: DNS leak protection ensures that 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 ensures that IPv6 traffic is also secured. You can use the built-in leak testing tool in the 91 Accelerator client or visit third-party detection websites to verify your protection status.
91 Accelerator's self-developed obfuscation protocol disguises accelerator traffic as regular HTTPS traffic, effectively countering deep packet inspection (DPI) technologies. In environments with strict network restrictions, 91 Accelerator's obfuscation mode can help users break through blocks and regain access to the free internet. However, please note that 91 Accelerator advocates responsible use of accelerators in compliance with local laws and regulations.
91 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 can offer additional anonymity. All payment channels are processed through PCI DSS certified secure gateways, ensuring your payment information is secure.
91 Accelerator has deployed over 3000 servers in more than 80 countries and regions globally. Key coverage areas include: North America (over 30 cities in the US, 5 cities in Canada), Europe (25 countries including the UK, Germany, France, Netherlands, Switzerland), Asia-Pacific (15 countries including Japan, South Korea, Singapore, Australia, India), South America (Brazil, Argentina, Chile), and the Middle East and Africa (UAE, South Africa, Turkey).
Yes, 91 Accelerator provides browser extensions for Chrome and Firefox. The browser extensions run lightweight and only encrypt traffic within the browser (not affecting other applications). They are particularly suitable for scenarios requiring quick IP location switching, such as cross-border shopping comparisons. The browser extensions also include built-in WebRTC leak protection and ad-blocking features.
