Hi gmatamis,
Recently I had to replace my wireless-G system that had been in use for about 4 years (and worked quite well) with a new system because lightning got my router. My old system was all D-link except the Linksys wireless bridge that tied my ACIII to my d-link router. With this sytem, all worked well overall, but every once in a while, I got "Aquacontroller not responding". I think my signal was the issue.
About 6 weeks ago, I replaced my whole network with Wireless-N.
Router = DLink DIR-655 (main computer is wired to this via ethernet cable.
Wireless Bridge (Gaming Adapter) = Linksys WGA600N
Notebook adapter = DLink DWA-652 .
This combination has worked flawlessly so far. I also got the ANT24-0230 and replaced the 3 small antennae on the router with it. The increased range and reliability has meant that I have gotten NO 'Aquacontroller not responding" messages yet. Aquanotes runs 24/7 on this system.
This combination has worked extremely well for me. It took about a day and a half to set up because I rerouted some of the wiring in my office for a cleaner look, but setting up the parameters/IP's etc. only took an hour or so.
Hope this helps.
