We were in the field with Marcel Colnot having blue screen issues with Iqan 3.19. We decided to update the program to 4.01 and try that and the program would not finish loading through an ASUS WL-330NUL when computer was connected wirelessly to the router (it would get to the end but after restart it went to blue screen - it appeared to be looking for an IP address). We had to take out the address tag and load it with a wired connection direct to an Ethernet port on his computer. I have a suface which has no Ethernet port - I have used the wireless adapter with no problems up to 4.01.
Marcel can give you more details if necessary.
