Query: Terrible

I bought this router as an upgrade from my Netgear wireless g router. As soon as it was installed I started losing connection intermittently and on several occasions couldn't connect at all. My son has an Xbox and he also was having a lot of issues with the online gaming. After four days we switched back to the Netgear router and all the previous issues were gone. This will be my last D-Link purchase.
