Wow!!!
I was surprised to heard so much negative thoughts about the WHR-300N and Buffalo in general, as a matter of fact, I have been using WHR300N for close to a year and to tell you frankly, I think it is a very good and efficient router.
I am not an expert in wireless router....I just used the router for wireless and wired feature to surf the net and download some. So far, it has not failed me. I lived in a average sized apartment, and due to the limted space, I placed the WHR300N under my table in my study wired to a PC and another 2 notebooks around the apartment runnign with wireless features.
The wireless was able to give Excellent and Very Good range (according to the http://tools.meraki.com/stumbler). I have friends that came to my home and was surprised to see my router stack under the table....they told me that their router could not even come closed to what the WHR300Nhas given me.
Out of fun, I purchased another wireless router (NetGear 200N), it was not able to give such good range and their service was in my opinion worst than Buffalo Tech. I was glad to gave it away and keep my WHR300N.
Anyway, I am here to give my frank opinion and feedback. Thank you for your time and Good Luck.
