I'm working with a client to set up some new Audio/Visual equipment for conference calls in their conference room (which resembles a small classroom with stadium seating, like you would find on a college campus).  So far I have the video working (Using Marshall Electonics IP cams with Roland video capture all run through a Mac) and the sound working (multiple hardwire and wireless mics).

They have asked me to add in a Listen Technologies system as the company owner uses hearing aids and gets frustrated with what he does/doesn't hear.  This system connects to the soundboard for the and then will broadcast the sound via wireless to the app on his phone.  His phone bluetooths to his hearing aids so he will have soundboard quality directly in his ear.

Here is the kicker....the Apple comp connects directly to their office internet which is networked and they don't want to give out the password for this network as often they have guests and other industry folks in the room for conference calls.  I ran a hardline for the computer for buffering reasons and I really don't want to have to run a second one....so, here is the question:

Can I install a cheap router that is wireless but also has 2 ports on it and use it within the system?  I can password just that router and then wouldn't be giving out the main password.  I tried to explain that even then people are "hooked into" the network but they want something different (probably just for optics).  

Main network is wireless and wired.  I would take the wired connection and install a secondary wireless router.  That would a) provide a wireless they could give out and b) give a network solely for the Listen Technologies hardware.  I could run a hardline off the wireless router to the Apple Computer for video conferencing to prevent buffer issues.

In my brain this can be done and I won't have to worry about channels or latency but I feel like I am missing something.

Yes.  They have a guest network already.  The access point is literally right beside the computer.  But in order for the LT stuff to work it has to be hardwired, which means the guest network wifi won't be able to be utilized.  That was setup prior to me being on this job.  Their network is complex and usually more than I do.  I has 2 different security camera systems, multiple computers, copiers, etc.

Have the DHCP already set because of all the access points around the building.  Installing the new one would require not having it be a DHCP server.

So digging more into this....3 of the 4 SSIDs are taken but one of the 3 is not being utilized and was set up for packet priority.  I am going to reconfigure the port for the hardwired line to that SSID and get their stuff all on a single SSID away from their main account password.  One of my local contractors is coming in to help tomorrow since this is more his wheelhouse.
