Connectivity issues on Mudi V2 (GL-E750V2)

Technical Support for Routers
1

Hello there,

I have been trying to use the Mudi V2 in a few scenarios and have been facing the following issues:

  1. When data-roaming to China, ShenZhen, the router would often just give "No Internet" error on the screen and be unusable. I will have to power cycle the router and hope it works (60% of the time, it will work for a few minutes, then show good signal with China Mobile and "No Internet" comes up again. The other 40% of the time it will show no signal.). Taking the SIM card out and putting it into my Samsung handphone would work just fine.

  2. When data-roaming to Malaysia, Johor Bahru, the router would give a similar issue as point 1, but unlike in China it will never show no signal as it will show that it is connected to the carrier. Unlike in China, the router will stop working (no WiFi signal) despite being turned on and showing "No Internet" on the screen. Taking the SIM card out and putting it into my Samsung handphone would work just fine.

  3. When using in Singapore, the router appears to work just fine, although it will not switch carriers properly when switching from Malaysia carrier to Singapore carrier, and I have to power cycle the router just to get it to work again.

Is there any advise on what could be done? I have tried this same SIM card in other MiFi routers and it works just fine without any hiccups, and also in my Samsung phone with no issues at all.

Hello,

Is this card a physical ordinary SIM card (Roaming Activate), or a GLiNet eSIM card?
What the SIM card original ISP is?

Please try upgrading the latest firmware first.

Hello Bruce,

This is a physical ordinary SIM card. The original ISP is CMLink Singapore (China Mobile), which is an MVNO of Singtel.

Firmware is at latest version.

Hi @NicholasChanCJ
Could you provide the following info when No internet error occurs again:

  • the system log. Export it from the admin panel->SYSTEM->log
  • the modem-debug file. Download it from admin panel->INTERNET->Cellular->Modem Management, as shown below:

    You can PM me the message.

Hi Cathy,

I will get the information as requested. For now, I can only get for Point 2 (roaming into Malaysia) and Point 3 (normal usage in Singapore) for now, and will get the information for Point 1 (roaming into China) sometime in a few months and PM you.

Thank you.
