Dual Band Wifi Problem

[Jr1985]

So I'm trying to connect my MBP to my new Belkin Double N+ (F6D6230uk4) router. I have 2.4 ghz set to b/g and 5 ghz set to n and 20/40hz bandwidth.

Last night, when I connected to the router for the first time, I was showing 300mbps, when you Options+click the Airport icon. However, now I'm only showing 145mbps. To be fair, I may have changed a few settings between now and then, but I have no idea how I was able to get 300mbps before.

It's as though it's only connecting to one channel, instead of two, which is required for 300mpbs I think?

I have an Apple airport extreme. I have the same settings as you, 2.4ghz for b/g and 5.0ghz for n.

My speed also varies between 130 and 300mpbs. I believe the fluctuation is due to varying signal strength. Even when I am sitting in one spot, it will vary. I checked on my iMac and it does something.

Well I returned the Belkin and bought an Airport Extreme instead. Problem solved, as I'm now getting a much higher Transmit Rate, I'm able to connect further away from the router, and I saved £5 with student discount
