关于LAN连接二级TP-Link路由器的距离问题咨询 #

Hey there! Let's break this down for you clearly.

First off, the good news: 80 meters is totally within the safe range for a standard Ethernet connection. Here's the background: most common Ethernet cables (like Cat5e, Cat6, or Cat6a) have an industry-recommended maximum transmission distance of 100 meters. Your 80-meter run doesn't hit that threshold, so it should work perfectly fine in theory.

That said, a few practical tips to ensure a stable connection:

• Invest in quality cables: Don't go for cheap, unbranded wires. Pick a reliable Cat5e or higher cable (TP-Link's own cables are a solid option) — low-quality cables can cause signal loss even before reaching the 100-meter limit, leading to slow speeds or intermittent drops.
• Skip unnecessary joints: Every splice or connector adds a risk of signal degradation. If you absolutely need to join two cables, use a proper RJ45 coupler instead of makeshift connections.
• Avoid interference sources: Keep the cable away from large power equipment like air conditioners, transformers, or heavy machinery. These can disrupt the Ethernet signal and cause issues even at shorter distances.

If you set it up and run into odd problems like dropped connections or sluggish throughput, double-check your cable quality and routing first — those are the most common culprits in longer runs.
