I have a DWA 140 revB range booster and Windows XP SP3. Recently, I have experienced problems whereas I am connected to the Internet but the IP addresses keep expiring and I can't load pages. However, I still have an Internet connection signal. I have tried clearing the DNS cache, but the problem keeps reoccurring. Occasionally, I also get the error message regarding "ANIWZCS2 has encountered a problem." I had previously gotten this message in the past, before my recent problems occurred. However, I use to click OK and everything was fine, but now it's not. The Internet page cannot seem to resolve the host. I checked "Start UP" when running msconfig, and there is no ANIWZCS2 box to uncheck. I have a AT&T U-verse Wireless router in another room in the house and a Belkin extender in the room with my computer. I am not sure if my problems are due to my wireless AT&T U-verse router, Belkin extender that is near my computer or the D-Link range booster. My laptops that are in the same room with my U-verse router work fine. I have also shut down and turned on my AT&T U-verse router and Belken extender, but it does not help. AT&T gave me the DWA 140 when they installed it, but they did not give me the CD that goes with it. Any help would be appreciated in getting this problem resolved.
