Qosmio x505-896 can't find N network

I was hoping someone could help me figure out why my Qosmio can't find my N network. I have a M11x that is finding and connecting to the network just fine. My Qosmio can only find the G network.

I am using a Netgear Dual Band Wireless-N router WNDR3300.

 

Any information about driver? And I'm not familiar with your model but any option in BIOS?

 

The network adapter is a Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC and I just updated to the latest driver 2015.1.427.2010.

I can see other N networks in range (I live in an apartment complex) but I can't see the N network for my own router.

I looked over the BIOS and didn't really see anything that would really help but I'm not sure if I missed something that wasn't really obvious.

I'm really hoping I don't end up having to buy a new router since everything else I have seems to find it just fine.

 

Ok so I found out that my Qosmio can only find networks at the 2.4 Ghz range with the adapter in it. This is pretty disappointing since I was running G at 2.4ghz and running my N at 5ghz. I set my router to only run N up to 270 Mbps at 2.4 Ghz and my Qosmio could find it.

However, even more disappointing is the fact that after connecting the Qosmio to N at 2.4 Ghz, it was only connecting at 54 Mbps. My M11x was still connecting to it much higher. Is this normal for the network adapters they have in the Qosmio x505 line?

 

You've already mostly answered your own question. The nic in the Toshiba is a single band and not dual band.

HOWEVER, running N on the 2.4Ghz range sorta can be done if 2 channels are available and unused. If you live in an apartment with lots of signals, you're probably out of luck and you'd be better off buying a cheapo USB dual band dongle and moving to the 5ghz range like I did. Still tho, you SHOULD be getting better than 54Mbps unless, of course, you have a Wifi B class device connecting on your same network.
