Summary: It's difficult to know how to rate this router. I chose it specifically because it's one of the few ADSL modem routers that have a build of the open-source DD-WRT firmware available for it. Upon receipt, I decided to try the router with its standard Buffalo firmware. I set it up, all went well, and all my devices (wired and wireless) worked fine. The next morning, none of my wireless devices could access the internet. I rebooted the router, and all was well again.
Summary: I bought this router to replace my Linksys WAG160Nv2 which was not givign me range in few rooms of my apartment in kuwait. Installed the router and felt happy about hte range and speed untill i got up next morning and found the router working normally but with no internet. Called Buffalo Help desk , found them very methodical and helping. I was told by them that the device had defect and i could replace it. I got he replacement after two days but found the same problem.
Summary: I had been struggling with poor coverage through the house since I switched to fibre service from my ISP and so had to stop using the combined modem/router that I had before . The route supplied by the ISP was a bit feeble and because of where the BT line terminates had to be right at one end of the house. This led to poor coverage at the other end.
Summary: Ok, the positive first - this router has fantastic range and is really fast. It comes with "drt-ww" firmware (google for more details), so is incredibly configurable, and also comes with a CD which enables you to install a more simple user friendly firmware. It handles different wifi standards flawlessly and seems really stable. Now the problems - it is terribly designed.
