FAQ
Everything you need to know about Comet Accelerator
What is the essential difference between Comet Accelerator and other accelerators on the market?
Comet Accelerator differs from traditional accelerators primarily in its underlying protocol. Most accelerators still use IPsec or IKEv2, whereas Comet Accelerator fully adopts the WireGuard protocol, which comprises only 4000 lines of code (more than 600,000 lines for IPsec), delivering speeds 3-5 times faster while significantly reducing battery consumption. Furthermore, Comet Accelerator’s no-logs policy has been validated by Cure53’s independent audit, with the report made fully available, ensuring a perfect balance of speed and security.
Which operating systems and devices does Comet Accelerator support?
Comet Accelerator provides native clients for all platforms, supporting Windows 7 and later, macOS 10.14 and later, iOS 14 and later, Android 6.0 and later, as well as major Linux distributions (Ubuntu, Fedora, Debian, etc.). Additionally, Comet Accelerator offers detailed router configuration tutorials for mainstream router firmware including Asus, Netgear, and OpenWrt, enabling whole-home coverage for all connected devices with a one-time setup.
How can I request a refund if I'm unsatisfied with Comet Accelerator?
Comet Accelerator offers a 30-day unconditional money-back guarantee. If you aren’t satisfied with the service within 30 days of purchase, simply reach out to customer support via online chat or by emailing support@vpnjs.net without needing to provide any reasons, and you can request a full refund. Refunds are typically processed back to your payment method within 1-3 business days.
What is the actual connection speed I can expect with Comet Accelerator?
Comet Accelerator has over 3000 high-speed server nodes worldwide. According to actual tests: the average latency when connecting to Asia-Pacific nodes is under 30ms, while connecting to North American nodes sees latency around 80-120ms, with download speeds consistently exceeding 500Mbps on gigabit broadband. Thanks to the efficiency of the WireGuard protocol, Comet Accelerator maintains stable and smooth connections even in complex network environments.
What does Comet Accelerator's no-logs policy entail?
Comet Accelerator's no-logs policy covers all aspects: we do not log your original IP address, connection timestamps, websites or domains visited, DNS queries, or bandwidth usage data. All servers run in pure RAM, 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 Comet Accelerator's official website.
Comet Accelerator provides detailed router configuration tutorials, supporting popular router firmware such as Asus (Asuswrt-Merlin), Netgear, Linksys, and OpenWrt. Configuration steps typically include: 1) logging into the router's management interface; 2) going to the acceleration client settings; 3) importing the configuration file provided by Comet Accelerator; 4) entering your Comet Accelerator account credentials. Once configured, all devices connected to that router's WiFi will automatically receive accelerator protection without needing to install clients on each device.
Yes, Comet Accelerator is specifically optimized for streaming performance. Our high-speed nodes can smoothly play 4K ultra-high-definition video content. Comet Accelerator regularly updates its server IP pool to ensure a stable streaming access experience. However, please note that Comet Accelerator does not encourage users to violate the terms of service of any streaming platform.
Thanks to the efficient design of the WireGuard protocol, Comet Accelerator has minimal impact on speed. In most cases, speed loss is limited to 5-10% of the original bandwidth. In some situations, if your ISP throttles specific traffic (like video streaming or P2P), using Comet Accelerator may actually improve your speed since the encrypted connection prevents the ISP's deep packet inspection (DPI) and traffic identification.
Yes, the Lightning Version of Comet Accelerator supports up to 6 devices connected simultaneously, while the Premium Version supports up to 10 devices. This means you can use accelerator protection on your smartphone, computer, tablet, smart TV, and other devices without incurring additional fees. For even more devices, it is recommended to configure Comet Accelerator on your router, which will protect all household devices with a single setup.
Public WiFi is a high-risk scenario for hackers to steal data. After connecting to Comet 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 in the case of man-in-the-middle attacks or sniffing. Comet Accelerator also offers an automatic connection feature: when detecting an unsafe WiFi network, the accelerator protection will be activated automatically.
Yes, Comet Accelerator's no-logs policy has been independently audited by the internationally recognized security firm Cure53. The audit team comprehensively examined Comet Accelerator's server infrastructure, codebase, and operational procedures, confirming that Comet Accelerator does not log any identifiable user data. The complete audit report is publicly available on Comet Accelerator's official website.
Yes, Comet 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, 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.
Yes, the Premium Version of Comet Accelerator includes a dedicated static IP address. A static IP is 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. The static IP is exclusively assigned to you and will not be shared with other users.
Comet Accelerator features a comprehensive leak protection mechanism: DNS leak protection ensures all DNS queries are resolved through encrypted connections; WebRTC leak protection prevents browsers from exposing your real IP through WebRTC interfaces; IPv6 leak protection ensures IPv6 traffic is also protected. You can use the built-in leak testing tool in the Comet Accelerator client or visit third-party testing sites to verify your protection status.
Comet Accelerator's proprietary obfuscation protocol disguises accelerator traffic as standard HTTPS traffic, effectively countering deep packet inspection (DPI) technologies. In environments with strict internet restrictions, Comet Accelerator's obfuscation mode helps users break through blocks and regain access to a free internet. However, please note that Comet Accelerator advocates the responsible use of accelerators in compliance with local laws and regulations.
Comet Accelerator supports various secure payment methods: Visa/Mastercard international credit and debit cards, PayPal, Alipay, WeChat Pay, as well as cryptocurrencies (Bitcoin, Ethereum, etc.). Choosing cryptocurrency payment can offer additional anonymity. All payment channels are processed through PCI DSS certified secure gateways to ensure your payment information is safe.
Comet Accelerator has deployed over 3000 servers in more than 80 countries and regions worldwide. Major coverage areas include North America (30+ cities in the United States, 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.).
Yes, Comet Accelerator offers extensions for Chrome and Firefox. The browser extensions run lightweight, encrypting only the traffic within the browser (without affecting other applications). They are particularly suitable for scenarios requiring quick IP location switching, such as cross-border shopping price comparisons. The extensions also include WebRTC leak protection and ad-blocking features.

Our customer support team offers bilingual service in Chinese and English.
Comet Accelerator Lightning and Premium Versions include ad-blocking and malware protection features. This operates at the DNS level, blocking the loading of ad trackers, malicious domains, and phishing sites by maintaining a blacklist of over a million rules. This approach is more efficient than traditional browser ad-blocking plugins, as it prevents unwanted connection requests at the network layer.
