The TP-LINK7260V1 version always drops when dialing up the Internet

Problem description: The latest official firmware used by TP-LINK7260V1 always drops from time to time, sometimes it drops in 1 and a half days, sometimes it drops for a few hours, sometimes it just drops, and then it drops again after a few minutes.

Recommended Resolution Steps

Step 1: Basic Troubleshooting

1. check the power adapter temperature - if it is hot, it is recommended to replace it with a higher power one (such as 12V2A)
2. Improve cooling - Elevate your router to avoid placing it in an enclosed space
3. Replace the network cable - Try replacing the network cable connected to the optical cat
4. Observe the Light Cat Indicator - See if the Light Cat also restarts when the line drops

Step 2: Downgrade or flash third-party firmware

• downgrade to an older stable version - find a firmware version with a good reputation
• Brush Padavan (Lao Maozi) Firmware - Enshan Forum There are many adapted versions of 7260, and the stability is usually better than the official
• brush OpenWrt - best stability if adapted version

Step 3: Adjust the dialing settings

1. go to the router's background and find the WAN port settings
2. try turning on Auto-Reconnect or Auto-Recover Disconnection
3. adjust the MTU value to 1492 or 1480 (required by operators in some regions)
4. turn off IPv6 try (sometimes IPv6 causes instability)

Step 4: Check for hardware failure

• Router hardware failure (capacitor aging, etc.)
• the light cat fault (let the operator replace it)

Temporary contingency plans

• set scheduled restart (e.g., automatic restart at 4 a.m. every day)
• use the smart socket and remotely power off and restart if the connection is dropped

Suggest next steps

1. try downgrading the firmware - if the latest version is unstable, fall back to the previous version
2. consider flashing the Padavan firmware - this is a common solution for troubleshooting TP-LINK's official firmware
