I have 4 D-Link DWL-3200AP Access Points deployed in a client and two of them have quit working after 2 years of use. I am going to replace them with more of the same unless some of you have a better suggestion. I have considered using Cisco Aironets, but the price is sort of out of budget range and I am not a certified Cisco tech. I have all of the AP on the same SID and same channel to allow roaming between AP's. The D-Link's are about $200 new, I think the Cisco devices are $350-400 new. If you know of something else that works well in a commercial environment, let me know. These AP regularly have 30 clients connecting to them. I don't think that a consumer grade AP would be reliable. Thanks for any input.
