MR5200 won't attach to n77 after firmware update - multiple questions!

Sorry to hear the latest update cause some issues on your devices. We will investigate

Could you please advise which carrier you are using? 

As for downgrading failure to older release using local update file, this is by design. Upgrade setting is enabled by default and can't be disabled by end users.

I have a number of MR5200 that I use for testing locally on a local network... The old firmware (NTGX55_10.29.11.00) worked really well on my band 3 / n77 5G NSA setup however a newer firmware that got pushed onto one of the devices (NTGX55_12.03.09.00) doesn't seem to associate to the n77 band anymore.

 

Doing a good amount of digging - I've got hold of the old firmware file (the secc.cwe file - which I've renamed to .spk per other forum posts) - however trying to reload it on the "updated" device gets an Error Code 16 in the web admin firmware uploader. Any thoughts here?

 

The second thing I'd like to do is disable software update on these devices - there doesn't appear to be an option - is there a hidden setting?

 

The third thing I'd like to do is get this issue fixed - I've tried the official support and its taken a week, and I'm barely past the "can you confirm that you've tried the sim in another device" question..

 

I've got hold of the model.json off devices with the old / new firmware - you can see the one that works here:

 

"diagInfo": [  {
"lteAttached": true,
"nr5gAttached": true,
"endcEnabledConfig": true,
"ltesigValid":true,
"ltesigRssi":"-68 dBm",
"ltesigRsrp": "-85 dBm",
"ltesigRsrq": "-7 dB",
"ltesigSnr": "29 dB",
"nr5gsigValid": true,
"nr5gsigRsrp": "-92 dBm",
"nr5gsigRsrq": "-11 dB",
"nr5gsigSnr": "17 dB"
},{}],

 

and the one that doesnt here:

 

"diagInfo": [  {
"lteAttached": true,
"nr5gAttached": false,
"endcEnabledConfig": true,
"ltesigValid":true,
"ltesigRssi":"-64 dBm",
"ltesigRsrp": "-82 dBm",
"ltesigRsrq": "-8 dB",
"ltesigSnr": "29 dB",
"nr5gsigValid": true,
"nr5gsigRsrp": "-32768 dBm",
"nr5gsigRsrq": "-32768 dB",
"nr5gsigSnr": "-3276 dB"
},{}],

 

Something definitely looks "not right here". From the base station side - the netgear is sending in measurement reports for the NR radio - it just doesn't bring up the userplane on it.

 

As a final issue - I've noticed some MTU issues when using these devices... I noticed a setting in the model for mtuChangeEnabled - any ideas about that? 

 

Any enthusiasts here that have some friendly pointers? For the application I have, the netgear works really well - this "auto updated" disaster is a bit of a pain!

Before upgrade, I can use 5G with china telecom and china unicom.

Also in model.json,

 i get same result:

"nr5gsigRsrp": "-32768 dBm",
"nr5gsigRsrq": "-32768 dB",
"nr5gsigSnr": "-3276 dB"
