We're currently using a Linksys WRT54G wireless router and I'm getting the feeling it is heading slowly into the bit bucket.
So, which brings me to a question or two:
• Would the Airport Express (current model) work as a wireless access point in venues where there isn't an open wireless access point?
• Has anyone used the old Airport Express in this capacity? (that's the model that hung off of the wall via it's power plug, currently a good deal at the Apple Refurb Store).
• I assume we could follow the directions elsewhere on this site to create an Ad-Hoc network with either. Is that correct?
• If you have used it, does it work well with wtkJams app?
We just want to set up the PA and plug the router into the wall and have it work consistently with the two iOS apps, wtkJams (preferred) or iJams (when the former doesn't work and that seems to be in venues where we have to use the above Linksys).
Thank you for any feedback and have a Great Thanksgiving y'all!

kind regards,
Mark & Anita
