Model: TL-MR100  
Hardware Version:
Firmware Version:

I bought a TL-MR100 two months ago and used it with a Vodafone mobile SIM card. Everything went well

until last week when the internet connection was suddenly lost.

 

At first, we thought it might be something wrong with the SIM card. We took the SIM card and inserted it into the phone, it worked.


We have another backup SIM card from Optus, which also works on the phone. We inserted the Optus SIM card to the router, and found out that only Apple products can be connected to the wifi but the speed is quite slow.


We have done a lot of research but still cannot find the solution.

 

Can anyone help us with this issue please?

Hi, you may test using your two SIM cards from Vodafone and Optus separately on the router to confirm whether it shows "SIM card prepared".

If so, please upgrade firmware(Local upgrade) to latest according to the official website.

Then, it is suggested to follow steps in the troubleshooting guide.

Hi Marvin  @Marvin_S ,

 

Thanks for your reply.

 

I've checked the link you shared. But strangly, in my case, there is no IP address showed in the Internet window on Status page under Advanced.

 

The hardware version is TL-MR100 v3.0 00000002, and the firware version is 1.3.0 0.9.1 v0001.0 Build 231101 Rel.58526n.

Re:TL-MR100 suddenly not working with Vodafone and Optus SIM cards

I have a similar issue.  Was working fine for many months until a few days ago after which some devices (Phones, TV, TP-Link Cloud & Firmware upgrade on Modem) would connect, but had no internet access while other devices continued to work (Laptops, iPad).  For Firmware upgrade etc shows "Internet is unavailable" while status on modem shows it as available.  Diagnostic Tools pass.

 

I swapped the out the Vodafone sim from the MR100 for a Telstra one momentarily and all devices then worked fine. 

Putting the Vodafone SIM back resulted in the issue resuming.

Have tried manually upgrading the firmware as well as reset to factory.  Bought a new MR100 - same.

 

Something to do with Vodafone  TPG network merger???

I wonder if its related to the recent optus / telstra 3G shutdown.

 

1-Make sure the MR100 network mode is set to '4g only'

2-create a new static APN:  live.vodafone.com  , IPv4, authentication=PAP,  leave username and password blank

 

Another less likely scenario is the MR100 has been blacklisted by the isp - confused with phones that 'may not' make 000 calls.

  @ng6333 

Thank you.

 

Not related to 3G shutdown and works with all devices if I substitute in a SIM using Telstra.  Some of the devices like TV have no knowledge of 3G or 4G.

 

Was set to static Vodafone as you referenced and was working with all devices until recently. Switched to Telstra and problem resolved.

 

But I remain curious as to what seemed to have changed on Vodafone/ Felix.

I can only think it maybe related to TPG or recent announcement of increased coverage and some how that is filtering through to WiFi which makes little sense

I would set DNS server on the router to 8.8.8.8, 8.8.4.4 (google dns) and test.

Could be something with vodafone dns.
