D-Link (the best and the worst)

D-Link offers 24/7 tech support and this is one HUGE reason why I love this company. HOWEVER, I recently bought a dual 802.11a and 802.11b wireless access point. I also bought a 802.11b and 802.11a D-Link network card (USB and PC Card). For some reason I could not get the 802.11b (11Mbps) card to work. I called D-Link tech support seveal times and got a variety of answers in my LAST call I was told that the firmware of the access point needed to be upgraded!!! But my frustation with them and with CDW (the retailer) is why was this not told me before. Why in the world would D-Link even SELL and market a productd as 802.11a and 802.11b compatible if it does not work this way out of the box! What a shame.
Two problems here – a incompetant tech support staff who should have KNOWN of this KNOWN issue and flagged it first and secondly why D-link is practicing deceptive marketing.
