关于4G路由器远程MySQL连接Tracert跳点及路由的技术咨询

Let’s walk through your traceroute results one hop at a time, and unpack why that 4G router might have played a role in your initial slow connection.

What Each Traceroute Hop Means #

• Hop 1: 192.168.2.1
  This is exactly your 4G router’s default gateway—your device’s first stop when sending any traffic out to the internet. No surprises here, since you already noted this address.

• Hop 2: MIKE-PC [192.168.225.1]
  This is another device on your local network—probably a PC, secondary router, or switch that your traffic passes through before hitting the 4G router’s upstream connection. It’s still inside your home/office setup, not part of the public internet.

• Hops 3 & 4: 192.168.213.21 / 192.168.213.22
  These are private IPs belonging to your 4G carrier’s internal network. Think of them as the first steps your traffic takes once it leaves your router and enters the mobile provider’s infrastructure—like their local towers or regional hubs.

• Hops 5 & 6: Request timed out
  Don’t stress about this! A lot of ISPs (including mobile carriers) configure their network gear to ignore traceroute’s ICMP packets to save bandwidth or for security. This doesn’t mean your traffic was dropped—your later hops prove it made it all the way to the database server.

• Hop 7 onwards: 63.130.104.194 & beyond
  These are public IP addresses from the internet backbone or your MySQL server’s hosting provider. From here, your traffic travels across the public internet to reach its final destination.

Why 4G Could Have Caused Initial Slowdowns #

Since you’re using a 4G router, here are a few likely culprits for the initial slow connection:

• Variable latency: 4G networks often have more jitter (unpredictable delays) than wired connections, especially if your signal is spotty. This can make the initial TCP handshake (which MySQL relies on to establish a connection) take longer.
• Peak-hour congestion: Mobile networks get busy during rush hours—those carrier hops (3 and 4) might have been backed up earlier, causing your traffic to wait in queues.
• Routing adjustments: Carriers sometimes tweak their internal routes. The speed improvement you’re seeing could mean your traffic is now taking a more direct path to the database server.

Quick Checks to Keep an Eye on Things #

• If slow connections come back, run tracert again to compare routes—this can help spot if specific carrier hops are causing delays.
• Check your 4G signal strength; weak signal leads to more retransmissions and slower speeds.
• If your router supports it, test with a wired connection to rule out 4G-specific issues entirely.
