Hello, I'm using a Huawei E1752Cu unlocked to any carrier, the E1752 is in the supported list.
I configured openwrt, everything working fine.
I moved router to an other house where I want to use it, I have no UMTS coverage.
It never connects, I have a "No carrier" error.
Everything looks to work OK in the router.
Must say my ISP/cell phone provider uses another carrier but in both modes UMTS and GPRS.
Using the 3g modem connected to the computer I have GPRS connection, just the software say I'm in Roaming.
