Query: Don't purchase this D-Link product!!

I bought D-Link DIR-655 last October through Amazon.com.For 3 months,it had worked well. (not excellent, though)However, one week ago, after I tried to update DIR-655 it didn't work at all.Moreover, what drive me crazy is D-Link's support.Although I have contacted D-Link several times,they just gave me service phone number that always says me 'waiting' whenever I called to them.They never provide any reasonable service to me for the problem so far.I recommend you do not purchase this product unless you believe this would be never broken.You can not any service from D-Link.
