Troubleshooting No internet service on LTE Gateway Router
This Article applied to:
All LTE Gateway Routers
Troubleshooting suggestions:
Case 1. No SIM card or No SIM card detected
Please refer to this link:
[Troubleshooting] SIM Card not Found?
Case 2. SIM Card Status shows PIN Required
Suggestions:
Please go to Advanced>Network>PIN Management to enter PIN code and if you are not sure what PIN code is, please contact ISP to confirm it.
(Please do not keep testing the PIN code by yourselves since you might lock the SIM card.)
Case 3. SIM card prepared, but still no internet service.
1. Insert the SIM card into a mobile phone and enable the phone hotspot, then check if the hotspot works on other Wi-Fi clients.
2. Make sure the firmware is up-to-date.
3. Check the status page on the web UI and pay attention to the following information:
Network type+Internet IP address
Status A: Network type shows no service; ISP and other details are all "--".
Suggestions：
1.Go to Advanced>network>internet>WAN interface>Network mode> 4G preferred; Network search>Auto
If Network Type is still None, please check the supported network type and bands of the SIM card to see if they match with each other. (Take Archer MR600 for example, the supported network type could be found under the Specifications>Network Type )
Status B: Network type is correct but IP address is still 0.0.0.0.
Suggestions:
1.Go to Advanced>Network>Internet>WAN interface>Dial-up settings, and please check if there is another available profile in the Profile Name list. (If not, please go to Create Profile and manually input the APN details.)
Situation C. Network type is correct and IP address is not 0.0.0.0 but the internet is still not available.
Suggestions:
1.Go to Advanced->Network- >LAN Settings>DHCP server>change DNS to be 8.8.8.8/8.8.4.4
After the above troubleshooting, if still no internet service, please comment below with a screenshot of the status page and the hardware and firmware version of your product.

Hi, it seems that you are using a manually created APN profile, if you change it back to the default profile, will the internet work in Italy?
If not, please send an email to support.forum@tp-link.com with subject "Forum 273224", our engineer will follow up your case and might ask for a remote session to check it since you will move to other country soon.

@Sunshine The default profiles are also not working, especially in Swiss the IPv6 is the problem, so here only this one is working. In Germany this is also working, and sometimes in Italy this is also working, but just a little time!
I will send the E-Mail...

@Sunshine I think i found the solution, in Italy i need a different auth type, should be "PAP" in combination with IPv4 only... Works now for more than 15 mins :-)

@Sunshine I was to quick with my response... If i use my Router in "Wireless Router mode" and want to have the 3G/4G Backup, it wont work in Italy, if i switch to "3G/4G Router Mode" it works.
Today we left Italy and we are in Slovenia, till now everything works fine here even in "Wireless Router Mode" :-)
What is trating my little Router so bad in italy?
