Input:
Little did I know this when I purchased this product, and the wireless PCMCIA laptop card, to use with my new AOL DSL service! Nowhere is this noted - DLink says it is because of proprietary AOL software that none of their products are compatible w/ AOL. Only if you use another ISP to connect to AOL will it work (but that defeats the whole purpose). I tried and tried to get this product to work with AOL before I knew about this, I could get the wireless units to talk to each other but not to the DLS modem. Now I know, after talking to tech support.
I am giving this product 1 star because this is something that I expect them to note to potential buyers BEFORE they buy the product, since so many people use AOL these days. In addition, their product manuals are outdated (eg many of the screen shots are from Win95, so there are many differences between the pictures and today's systems), and the setup/administration programs are crude at best. I do have to say that my tech support calls were always answered within a few minutes, though - no problems there.
