Respected Sir/Madam,

 

For the past one month the router was working fine. Since last week the router was not able to detect the sim card and when we checked in http://192.168.1.1/ we are able to see the message "No SIM card detected or SIM card error”.

We have tried resetting and rebooting the router it didn’t work. The sim card works fine in my mobile and it has validity till 31.AUG.2019. I tried with another sim card still the same error from the router.

 

EAN : 6 935364080662
MODEL : Archer MR400(EU)  Ver: 2.0
S/N: 2191480000060
P/N: 176500015

 

 

Please help me in fixing the issue.

 

Thank you for your support.

 

With Best Regards
Hareharan V.V.R.

@Hareharan 

 

Thanks for your feedback.

 

Could you please send us the system log of the MR400 to do further analysis? Go to advanced-system tools-system log and hit save log, please send the txt file to us. 

 

How do you make it back to work after the error message pops up? 

 

Who is the sim card carrier?

I have the same issue.

Bought 2 TP-Link products in the last year and they are now both in the trash bin. Will never touch anything created by this company in my life

Hi, welcome to the community.

I see your model number is Archer MR400 v4.

May I know how long have you had the modem and when did this issue start?

And who is your sim card provider?

Thank you very much.
