第一步:如何正确选型?
Step 1: How to Choose the Right Plan

Q1. 我应该选择免费版、Pro 版还是企业版?

这取决于您的使用场景与预算。如果您只是偶尔访问海外网站、每天使用时间不超过 30 分钟,免费版即可满足基础体验;如果您每天需要进行跨境办公、观看 4K 视频或玩国际游戏,建议选择 Pro 专业版(¥49/月),享受不限速与 2000+ 节点;如果您是企业用户,有 10 人以上的远程团队,建议采购企业定制版,享受专属线路、管理员后台与 7×24 小时 SLA 保障。
This depends on your usage scenario and budget. If you only occasionally access overseas websites with daily usage under 30 minutes, the Free version meets basic needs. If you need cross-border office work, 4K video streaming, or international gaming, we recommend Pro (¥49/month) for unlimited speed and 2000+ nodes. For enterprise users with remote teams of 10+, we suggest the Enterprise Custom Edition with dedicated lines, admin console, and 7×24 SLA support.

Q2. 快连支持我的操作系统吗?

快连支持目前主流的所有操作系统:Windows 10/11(64 位)macOS 12 Monterey 及以上(含 Apple Silicon M1/M2/M3)、Android 8.0 及以上iOS 14 及以上。您可以访问我们的下载中心查看完整的支持列表。如果您使用的是 Linux 系统或其他嵌入式设备,我们提供 OpenWrt 固件与 Docker 镜像,欢迎联系技术支持获取。
Kuailian supports all major operating systems: Windows 10/11 (64-bit), macOS 12 Monterey and above (including Apple Silicon M1/M2/M3), Android 8.0 and above, iOS 14 and above. Visit our Download Center for the full support list. For Linux or other embedded devices, we provide OpenWrt firmware and Docker images — contact technical support for access.

Q3. 购买前我能先试用吗?试用版有什么限制?

当然可以!我们为所有新用户提供3 天 Pro 全功能免费试用,无需绑定支付方式。试用期间您可以体验全部 Pro 功能,包括不限速、全部节点、游戏加速、4K 流媒体等。试用结束后若未主动续费,账户将自动降级为免费版,不会产生任何扣费。
Absolutely! We offer all new users 3 days of full Pro functionality free trial with no payment method required. During the trial, you can experience all Pro features including unlimited speed, all nodes, game acceleration, 4K streaming, etc. If you don't actively renew after the trial, your account will automatically downgrade to the Free version with no charges incurred.

第二步:如何高效安装与使用?
Step 2: How to Install and Use Efficiently

Q1. 安装快连客户端的标准步骤是什么?

以 Windows 为例,完整安装流程共 5 步:① 访问 下载中心 下载最新版安装包;② 临时关闭 360、火绒等可能拦截虚拟网卡的安全软件;③ 右键安装包 → 以管理员身份运行;④ 选择安装路径(建议 C 盘非系统盘)并勾选"创建桌面快捷方式";⑤ 安装完成后重启电脑,确保虚拟网卡正确加载。整个过程约 2 分钟。
Taking Windows as an example, the complete installation process has 5 steps: ① Visit the Download Center to download the latest installer; ② Temporarily disable security software like 360 or Huorong that may block the virtual network adapter; ③ Right-click the installer → Run as Administrator; ④ Choose the installation path (recommend a non-system drive) and check "Create desktop shortcut"; ⑤ Restart your computer after installation to ensure the virtual adapter loads correctly. The entire process takes about 2 minutes.

Q2. 首次使用时,需要做哪些初始配置?

首次打开客户端,系统会自动引导您完成 3 个关键配置:① 登录账号:使用注册时的手机号/邮箱登录,勾选"记住密码"可下次自动登录;② 选择节点:建议保持默认的「智能选路」模式,系统会每 5 秒自动测试所有节点延迟并选择最优;③ 开启核心加速:点击主界面"⚡ 一键加速"按钮,等待 3 秒即可建立加速隧道。简单三步,即可开始畅享全球网络。
On first launch, the system will guide you through 3 key configurations: ① Log in: Sign in with your registered phone number/email, check "Remember password" for auto-login next time; ② Select node: We recommend keeping the default "Smart Routing" mode — the system tests all node latency every 5 seconds and selects the optimal one; ③ Enable core acceleration: Click the "⚡ One-Tap Acceleration" button on the main interface and wait 3 seconds to establish the acceleration tunnel. Three simple steps to enjoy the global network.

Q3. 如何根据业务场景优化加速效果?

快连提供了丰富的场景化优化选项:观看 4K 视频时,切换到「流媒体模式」,系统会自动选择带宽最充裕的节点;玩国际游戏时,切换到「游戏加速模式」,为 UDP 协议分配高优先级通道;跨境办公时,选择「企业专线」标签,使用专属 IP 出口避免业务平台风控。这些模式均在客户端主界面可一键切换,无需复杂配置。
Kuailian offers rich scenario-based optimization options: When watching 4K video, switch to Streaming Mode — the system automatically selects nodes with the most abundant bandwidth. When playing international games, switch to Game Acceleration Mode for high-priority UDP channel allocation. For cross-border office work, select the Enterprise Dedicated Line tag to use a dedicated IP exit and avoid business platform risk controls. All modes can be switched with one click on the client main interface, no complex configuration needed.

Q4. 安装过程中提示"数字签名无法验证"怎么办?

这是少数 Windows 用户可能遇到的问题,原因是 BIOS 中开启了"安全启动(Secure Boot)"。解决方法:① 重启电脑进入 BIOS(开机时按 F2/F10/Del,依主板而定);② 找到「Security」或「Boot」选项卡;③ 将「Secure Boot」设置为「Disabled」;④ 保存并重启后重新运行安装程序。若仍有问题,请提交工单联系技术支持协助。
This is an issue some Windows users may encounter, caused by "Secure Boot" being enabled in BIOS. Solution: ① Restart your computer and enter BIOS (press F2/F10/Del at startup, depending on your motherboard); ② Find the "Security" or "Boot" tab; ③ Set "Secure Boot" to "Disabled"; ④ Save and restart, then run the installer again. If the problem persists, please submit a ticket to contact technical support.

第三步:如何长期维护与升级?
Step 3: How to Maintain and Upgrade Long-Term

Q1. 客户端如何保持自动更新?更新会影响我的使用吗?

快连默认开启自动更新,当有新版本发布时,系统会在后台静默下载增量更新包(一般几 MB 到十几 MB),下载完成后会在您下次重启客户端时自动安装。整个过程无需人工干预,也不会打断当前加速会话。您也可以在「设置 → 关于 → 检查更新」中手动检查最新版本。建议保持自动更新开启,以获得最新的性能优化与安全补丁。
Kuailian enables automatic updates by default. When a new version is released, the system silently downloads incremental update packages (typically a few to tens of MB) in the background, and automatically installs them when you restart the client next time. The entire process requires no manual intervention and won't interrupt your current acceleration session. You can also manually check for updates in "Settings → About → Check for Updates." We recommend keeping automatic updates enabled to get the latest performance optimizations and security patches.

Q2. 长期使用后感觉速度下降,如何进行性能重置?

如果您使用 3 个月以上感觉速度不如从前,可以按以下 3 步进行性能重置:① 清理客户端缓存:在「设置 → 存储 → 清理缓存」,清除历史节点记录与临时文件;② 刷新本地 DNS:Windows 用户打开 CMD 执行 ipconfig /flushdns,Mac 用户在终端执行 sudo dscacheutil -flushcache;③ 重启路由器与光猫:断电 30 秒后重新上电,清除运营商侧的缓存。完成以上三步后重新连接快连,速度通常可恢复至初装水平。
If you feel the speed has decreased after 3+ months of use, you can perform a performance reset in 3 steps: ① Clear client cache: Go to "Settings → Storage → Clear Cache" to remove historical node records and temporary files; ② Flush local DNS: Windows users open CMD and run ipconfig /flushdns, Mac users run sudo dscacheutil -flushcache in Terminal; ③ Restart router and modem: Power off for 30 seconds then power back on to clear ISP-side cache. After completing these three steps, reconnect to Kuailian — speed should typically return to initial levels.

Q3. 如何管理我账号下的多台设备?

Pro 账号最多支持 5 台设备同时登录,企业版支持更多。管理方法:登录官网「账户中心 → 设备管理」,您可以查看当前所有在线设备的 IP、设备型号与最近登录时间。如需踢下线某台设备,直接点击该设备旁的「下线」按钮即可。建议定期检查设备列表,及时下线不再使用的旧设备,确保账号安全。若发现异常设备,请立即修改密码并联系客服。
Pro accounts support up to 5 devices logged in simultaneously; Enterprise supports more. Management method: Log in to the official website's "Account Center → Device Management" where you can view the IP, device model, and recent login time of all currently online devices. To kick a device offline, simply click the "Offline" button next to that device. We recommend regularly checking the device list and promptly removing old devices you no longer use to ensure account security. If you discover any suspicious devices, please change your password immediately and contact customer service.

Q4. 快连到期不续费,数据会保留吗?

订阅到期后,您的账号将自动降级为免费版,账号内的配置(节点偏好、使用习惯、收藏的节点列表等)将保留 180 天,在此期间续费 Pro 即可恢复原有配置。超过 180 天未续费,配置将被系统清理以释放存储空间。账号本身永久保留,您的历史订单、发票记录、客户支持记录均可随时查阅。建议至少在到期前 7 天完成续费,避免服务中断。
After your subscription expires, your account will automatically downgrade to the Free version. Your account configurations (node preferences, usage habits, favorite node lists, etc.) will be retained for 180 days, during which you can restore your original configuration by renewing Pro. After 180 days without renewal, configurations will be cleared by the system to free up storage space. Your account itself is permanently retained — your order history, invoice records, and customer support records are always accessible. We recommend renewing at least 7 days before expiration to avoid service interruption.
