Hi,

I recently bought a TP-Link MR600 router, and I’m experiencing frequent internet disconnects. The connection drops around 4 times a day, sometimes even more.

When the issue happens, all devices lose internet access temporarily. After some time, the connection usually comes back by itself, but it keeps happening repeatedly every day.

I checked the router logs and noticed this error message appearing when the disconnect happens:

“ERROR: Get runtime param for ip#1 failed (-1), result:0 , error:0”

Router model:
TP-Link MR600

Problem details:

• Internet disconnects multiple times per day

• Happens randomly during normal usage

• Connection restores automatically after a short time

• Error above appears in the logs when the issue occurs

Things I have already tried:

• Restarting the router

• Checking cables and SIM connection

• Updating/reinstalling settings

• Testing on multiple devices

I also found a forum thread where someone recommended downloading a beta firmware version to upgrade the router. However, when I try to upload the firmware file, I get this

error message:

“Error code: 71211
Failed to upload upgrade file. Please select the correct file.”

Because of this, I’m unable to test the beta firmware fix.

I would appreciate any help or advice on what could be causing this issue and how to fix it.

Thanks.
