M5 Nighthawk MR5200 Problem Acces Intern

Hello,

 

I am reaching out for assistance with my Netgear Nighthawk M5 router. I have a 5G Surf Unlimited subscription with Salt (Switzerland), and the SIM card works perfectly when used in my mobile phone (iphone), including when I use my phone as a hotspot.

 

However, when I insert the same SIM card into the Nighthawk M5 (MR5200), the device shows a strong 5G signal with full bars, but i can't acces web pages / internet.

Pages are not loading (one time i succeed by manually changing DNS to 1.1.1.1 and others stuff, but it was super slow, now i reset and nothing work...).

 

I would like to know if there are specific settings I need to adjust, such as DNS configurations or other network settings ?. I had the confirmation from Salt that they don't block / restrict acces to internt, so the problem comes from the M5 setting.

 I think the problem is coming from the APN settings. I wrote "internet" as suggested. Again it's connected but it seems to have no communication with the "internet".

 

I spent days on it... you are my last hope.

Thanks in advance

Pepito

    Hello ChePepito​ 

     

    Does this MR5200 carry an SKU (on the label under the battery, or on the retail package label) a MR5200-100EUS ?

     

    Please extract the model.jsonf file with the SIM card inserted:

     

    • Logon to the webui (http://192.168.1.1 ) as an administrator
    • Navigate to URL http://192.168.1.1/model.json via the same browser window
    • Capture the results (by selecting all + copy) and send it back

     

    Send PM with the file content to JohnPeng​ and mention your community ID.

     

    Regards,

    -Kurt.

    Hi,

     

    Thanks for you answer schumaku​ 

     

    Indeed it's written SKU: MR5200-100EUS --> what does it means ?

     

    this is the .json file in attached (It's kind of logs ? i was looking for that but i don't understand that much... anw thanks) .

     

    Meanwhile, i succeed 1 time to open a web page ! (and i put APN to: "chili", ive found online another APN for salt they said) but after it didn't work anymore...

     

    I looked at the statue of signal, it seems that all the time it "changes" frequency (pass from band: LTE B1 to B3), and when it is on B3 it seems-sometimes- it works. Can it be related to the stability of the frequency that doesn't work ? and my M5 try always to change dynamically ? (and i can't fix it's reception frequency). 

     

    Idk, i try everything now... thanks for your helped man.

    Hi,

     

    Still no answers and don't find any solutions... May i do update firmware manually ? On the website of netgear for the M5, it seems we only can make it from the app...

    I don't know what can I do with this M5... Does it exist some other "backdoor" menues / setting maybe to change directly from terminal ?
