@ne1gold I buy an other modem and it's the same. For everbody it's about the situation of covid-19 and many people on 4G antenna, so i will wait the end of this situation and see if something change....

@ReneB I've try to change SIM card and it's the same and I have restore to factory restore and nothing change!

@MrSlash I think if the problem isn't resolve, I will change my box for huawei. Ok the price is good and generally the equipment is perfect with tp-link but I can't stay like this with a new product...

@MrSlash So for you the problem will stay like this and they will never find solution?

@Baenz do you have solution about this problem?

@Guillaume_1978 When I use tp-link LTE Log Tool I have this message "unable to read router's information!"
