修复互联网连接问题
按照以下故障排除步骤,诊断和解决常见的互联网连接问题。
Power cycle your modem and router
Unplug both devices for 30 seconds. Plug in the modem first and wait 2 minutes. Then plug in the router and wait 1 minute.
Check physical connections
Verify all cables are securely connected: coax/fiber to modem, ethernet from modem to router, and any device ethernet cables.
Test with a different device
Try connecting another phone, tablet, or computer. If all devices fail, the issue is likely your router, modem, or ISP.
Try alternate DNS servers
Change DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1) in your network settings to rule out DNS resolution issues.
Flush DNS cache
Windows: run 'ipconfig /flushdns'. Mac: run 'sudo dscacheutil -flushcache'. Linux: run 'sudo systemd-resolve --flush-caches'.
Check ISP status
Visit your ISP's status page or call support. Outages and maintenance can cause intermittent or complete loss of service.
