Hello
I got a strange error with DWR-512 3g sim router. The sim was working until yesterday but now doesnt connect 3g data (says pin code rejected). i tested the sim on a phone and works well and the pin is the same as the luci.
i resetted to factory defaults and upgrade it to 19.07.4(the previous version was 19.07.03 and before upgrade it i resetted it with no luck.)
My sim is a Vodafone Spain card and tested in a phone and got the same pin and got data too(same apn too)
how i can fix/debug this? because its very strange because yesterday was working well (2 months working without issues and after this no modify and anything and doesnt work) i tried with another sim work and i have 2 days the same issue.
