Solve : New Laptop and Router?

1.	Solve : New Laptop and Router?
Answer» I just got the Toshiba Qosmio X505 and bought a new dual band (2.4/5ghz) wireless N Netgear WNDR3300 router. The trouble I am having is getting the laptop to recognize the N connection with dual band mode on. It doesn't find the N connection, but it finds the G connection just fine. I messed with the router settings and was able to get the router to broadcast in N only and the laptop found and connected to that, however it only was broadcasting in 2.4ghz. Is this normal or can I get it to broadcast in 5ghz on N only? Or is there some way to get the laptop to see the N connection when I have dual band mode on instead of just the G connection?Quote To achieve maximum output a pure 802.11n 5 GHz network is recommended. The 5 GHz band has substantial capacity due to many non-overlapping radio channels and less radio interference as compared to the 2.4 GHz band.[9] An 802.11n-only network may be impractical for many users because the existing computer stock is predominantly 802.11b/g only. Replacement of incompatible WiFi cards or of entire laptop stock is necessary for older computers to operate on the network. CONSEQUENTLY, it may be more practical in the short term to operate a mixed 802.11b/g/n network until 802.11n hardware becomes more prevalent. In a mixed-mode system, it is generally best to use a dual-radio access point and place the 802.11b/g traffic on the 2.4 GHz radio and the 802.11n traffic on the 5 GHz radio.[10] - Wikipedia The N spec has not been fully DEPLOYED.

Hey BC_Programmer, Just become a standard was published six months ago does not mean everybody has it RIGHT. Yes, the Toshiba has the N, but it does not let him choose which band.

But the problem with that is there is a shortage of that Toshiba right now. At close range the 5Ghz should give better performance that the 2.4 Ghz band in a congested area where is a lot of activity.

Different laptop, MacBook Pro booting from Windows, sees both the G and the N signal, so I know there isn't anything wrong with the router. This laptop recognizes both G and N, just not at the same time for some reason. Of course, I would rather be connected to N, I just don't know why my laptop doesn't recognize it when G is turned on. It does not show up in Wireless Connections. Thanks for the responses.Full model number is the Toshiba X505-Q875. So basically, when I set the router to only transmit in N signal, the laptop recognizes it, but only at 2.4ghz. Same with G. Just when dual band is on, it only connects to G at 2.4ghz, never N at 5.
