I have this unit 13 months today and the wi-fi quit working. Up until now it was great. Fast, reliable, etc.. Wired still works. Status says it is broadcasting, but SSID is nowhere to be found or shows up briefly with 0% strength. I can see all my neighbors less powerful routers, but not mine. After troubleshooting myself for several hours then on the phone with tech support for 2-3 hours, decided it was defective. BUT they will not replace the product since they only have a 1 yr warranty. I expect more service from my investment. I will not be replacing it with another Dlink.
