Historical Signal Record is not working

Not sure what devices affected, but on my Mudi V2 this page is empty. Never seen it working. Firmware is 4.7.2 beta.

Sorry it's a software bug. I’ve reported to the development team to fix it

For some reason this function is not available in the latest 4.8.3 beta. Also APN profiles has been removed. I cannot manage them anymore. I am a bit confused about this changes(?).

Router E750 does not support displaying historical signals. There was a problem in v4.7 and we fix it in v4.8.
With V4.8, it does not need to manually set APN profile. The APN details you set for a SIM card are automatically saved on the device and applied when you use that SIM.

So it will be operational in future releases?

And how the router store the profiles? Per provider/SIM/ICCID/phone number?

The APN feature is important to me, because many providers offering multiple APNs for several reasons. And changing between the profiles is lot more easier than typing everything all the time.

Sorry E750 will not add the historical signal display.
Router will store the profile based on various identifiers.

  • For traditional sim card, the router will remember the manual SIM card settings and apply it to the specific SIM.
  • For eSIM, if you‘ve set APN for a esim profile, it will automatically apply when you switch back to that profile so that you don't need to set it one more time.

I have a Puli AX with 4.8.3 and it is still not working.

Hi, is your issue that the historical signal records are not displaying, or that you cannot connect to the network? Could you provide some screenshot to show your issue?
If it's a new issue, you can create a new discussion thread.

The historical signal records is a blank page

Before upgrading Puli AX to V4.8, was the display of historical signal records normal?

Could you go to SYSTEM ->Log, at the top right corner click on "Contact Support" to send the required debug info to support to verify the issue? Pls include the post link in the description.

It has never worked. I got the router on June/July with 4.7.x and it was not working.

I sent the logs.

I gave a look at the JavaScript in gl-sdk4-ui-internet.common.js and the data I am getting from the router. The issue seems to be in this function block:

getSignalList() {
  (function (t) {
    return d("call", ["sid", "modem", "get_signals", t]);
  })({ time: this.time }).then((t) => {
    t.level && (this.level = t.level),
      (this.signals = t.signals || []);
  }),
    this.getSignalsTimeout();
}

This line (this.signals = t.signals || []) is expecting a signals array but there is no such array in the data I am getting from the router:

{"id":65,"jsonrpc":"2.0","result":{"level":{"NR5G-SA":{"sinr":[-6,0,6,12],"rsrq":[-24,-20,-16,-12],"rsrp":[-115,-110,-105,-100]},"LTE":{"sinr":[-6,0,6,12],"rssi":[-120,-110,-100,-90],"rsrq":[-20,-14,-10,-6],"rsrp":[-115,-110,-105,-100]},"WCDMA":{"rscp":[-112,-107,-102,-97],"ecio":[-120,-115,-110,-105]},"TDSCDMA":{"rscp":[-110,-107,-102,-97]},"EVDO":{"snr":[1,3,5,7],"rssi":[-105,-90,-75,-65]},"GSM":{"rssi":[-107,-103,-97,-89]},"NR5G-NSA":{"sinr":[-6,0,6,12],"rsrq":[-24,-20,-16,-12],"rsrp":[-115,-110,-105,-100]},"CDMA":{"snr":[-150,-130,-110,-90],"rssi":[-100,-95,-85,-75]}}}}

Pls enter the following command in the ssh terminal and try again:

uci set glmodem.signal.enable=1
​uci commit glmodem

it fixed it, thank you.
