Our Ion lightboard will not reliable connect to and remain connected with a laptop running the client software wirelessly. It is stable when it is connected via a cable, so I know that the problem is not with the software. I have discussed this with ETC and know that I need to filter out some information being sent out via the WAP. The one that we have will not allow me to filter the information out. It is an inexpensive WAP. My question is for anyone who has successfully set up their system to use the client software running wirelessly. What brand and model of WAP are you using in your system?
