I need advise on a brand and model of wireless access point to install in my coffee shop for my customer's use. For a reason that I have not been able to pinpoint, I have repeatedly had reliability problems with the consumer type access points that I have installed. My Asus RT-N66U has just died after about 8 months. It is the latest in a string of failed boxes that I have used. I have considered the possibility that humidity may be the culprit, but I have lots of other electronic devises in the same area that have worked for years without problems. At any rate, I need an AP that I can connect by hardwire to my network and provide a wireless guest account for my customers that will shield my internal network. The area of installation and use is indoors and mostly line-of-site and will need, at most, about 60' of coverage. I normally have no more that 5 users connected at a time. I do not need any type of log-in for the customer, just internet access. I think that the porn filter set on my Sonicwall firewall extends to the wireless guest accounts. I have no plan to expand coverage or use the AP for anything other that what is stated here.
