On LS units without sim card option we connect via hotspot to rtn. Lately, the rtn is greyed out even though wifi reception is excellent and internet access is "yes". I have to create a new profile (copy or edit will not work) and then it will work. But next time I turn it on rtn is greyed out again and have to create a profile all over again. Not sure when this came about, but first reported to me a couple weeks ago. When I go in to edit the profile it indicates APN in red and shows "...wifi, off". I check the sim card and it is off (don't have that option) but seems to be disabling connection to rtn via the hotspot as well. Any ideas how to fix this?
