Hi all,


I have just bought an Archer MR600 router and was trying to set-up 4G Internet connection but my card is not recognised.

I must say that I am from Romania and having a 4G SIM from Orange. I have also tried with a Vodafone one but still does not work. Error is SIM not detected


I tried also to set the ISP settings manually (from Orange / Vodafone website) but SIM card is still not recognised.


The third attempt was to upgrade the ISP with the one from the oficial website:

However, when trying to upgrade it I get error 71212 (Failed to upload isp file. Please select the correct file and try again).


Can you please help?


Best Regards,

Please try to insert the SIM card, then reboot the device and observe.


If you insert your SIM card to your mobile phone, are you able to get the Internet?


May I know which country are you located in?


Here is an instruction you can refer to to upgrade the firmware. From the picture, I notice that you have input a ZIP file, it may be wrong, you need to unzip it and choose the correct file.


BTW, what is the model number of your SIM card? And what is the network type of your SIM card?


Here is a link you can find the network type of Archer MR600, you can check if your SIM card supports this type:


Hope it can work and have a nice day!
