"Honestly, my confusion was with the term Access Point"
This is the issue at hand. I agree with Colin in the sense that I do not see how this is our fault.
"What Buffalo could do is possibly make a bigger deal about WDS on the products that have WDS"
I will send this request up for you.
"They could also enlist moderators with better customer service skills and more compassion for the consumer."
Colin is one of our best techs when it comes to customer satisfaction (if you don't believe me check out his profile/past posts). I believe that when he said the part about "watching your tone" he was giving you a fair warning before you got banned.
"Router - blah blah blah...
I feel THAT was a personal attack... listing definitions, implying that I don't know what those terms mean. "
This here could be considered a personal attack. Colin gave you definitions to help solve the self admitted "confusion" that you WERE having regarding acccess points/WDS. He didn't imply that you didn't know the definitions, you gave us that impression. In this very post you said that you were confused over the definition of "access point." Colin did what he could to quell your confusion.
I am sorry about your frustration regarding networking definitions and the inconveniences that this has caused you.
