Model: TL-MR6400  
Hardware Version: V7
Firmware Version: 7

Hello,

 

I have just updated the router firmware version to the latest.

Aftter that I updated my ESET Antivirus product and run a scan.

It detected the TP-link router opened port 23.

I check the admin wemsconsole and only find one option where I could disable TELNET, but the system didn't let to save this record.

Other than that, no record about port 23 or TELNET, there are no rules in port forwarding or in other services.

 

From my pc I can telnet to the router, but it ask for a password, which I don't know.

 

My network look like this:

INTERNET <- - - - - - - > Tp-link router <-------------> Desktop PC

 

<- - - - - -> = wireless connection

<----------> = wired connection

There is no ISP router in my network.

 

My questons are:

- Why is port 23 open?

- How could I close it?

 

Thank you!

Hi, thanks for posting question here.
May I confirm some information to know about your situation better?
1. Please take factory reset on the router and reconfigure it. And you may disable Remote Management to check again.
2. Please change another SIM card from another ISP if possible.
3. Please check and test on another wired/wireless client via ESET Antivirus product you mentioned via if possible.

It is also suggested to contact local support for direct help.
