Let me start off by saying I purchased this router as a replacement after our old router(WRT-610n) met its demised from a lighting strike. So after purchasing this item from www.bestbuy.com (cause the stores don't carry it in stock) when I received the unit in the mail I was so excited. On the box it stated "LAG IS NO LONGER AN EXCUSE". After a few fours of using this router my expectations was crushed, of course there was no lag so its not an excuse anymore, but router rebooting is an excuse. We have the total of 5 (3 desktop and 2 laptops) The desktops are hooked up on wired connection and 2 laptops are wireless. After a few hours of using this router it was going good. Then as soon as more people get on the other computers used the internet the router would reboot. So I've checked the d-link website and noticed there was a firmware update so i checked the router's firmware and it was 1.22NA so I download the new firmware and updated the router to 1.23NA. So after reconfiguring router and the wireless settings we started using like normal. Then again the router reboots. After days of this bull happening I called d-link. I told them our ISP and how many computers are connected. The tech support person told me to change the MTU from 1500 to 1450. Which didn't do Sh!t. The next day, I was so furious i took the router to the nearest bestbuy store and returned the unit. Paying $199.99 for a P.O.S that doesn't work. GOOD RIDDANCE! FYI, I bought the Linksys E3000 after I got my refund. Way better router than the DGL-4500
