Trying to use a Huawei E3372-325 4G dongle in Sweden with a TL-WR902AC v3 purchased in North America.

I loaded the most recent firware for Canada/USA and the 3G/4G page is showing connected but there is no connectivity. The dongle works fine in my laptop.

Have read other threads with similar issues, some fixed with a more recent or beta firmware, but there doesn't appear to be new firmware for the North American version
