Title: MacBook pro only connecting at 802.11g
Post by: loepxo on October 31, 2008, 07:48:24 AM

I just recently received my MBP and eagerly tried to use the 802.11n speeds to transfer data from my main PC to the mac.   However after setting up the wireless network it seems like it ONLY connects with 802.11n if the 802.11 mode is only set to (802.11n only)

I also have other devices that I am trying to connect to it (Wii, Xbox) and of course they need 802.11g.  So if I set the mode to (mixed 802.11g and 802.11n), the MBP connects at 802.11g and not at 802.11n.

Is there a way to force one device (the macbok pro) to connect only at 802.11n?

Is there a specific "Transmission Rate" or "Wireless Channel" setting that I need to change?

Thanks!

If I'm correct, when set to mixed  all connect's will downgrade to "g".

I have the same set up on my DIR-655 with firmware 1.21 and I am gettng only 130mpbs instead of 300mbps on my 17" Macbook Pro OSX 10.55   so I guess there is something missing on the DIR-655 firmware that DLINK should improve.

Also the range/performance speed from the DIR-655 is really poor degrading fast for every 10 ft added

Is the MacBook capable of using the 40 MHz channel ?  This is the only way you are going to see the higher speeds with the DLink.

I got a 17" MBP also, and I met the requirements or so I thought. 

Once I set the thing to 5 GHz, was I ONLY able to see a connection max of 270 Mbps.

I don't use a DIR-655, but rather a DGL-4500.

When in 2.4 GHz, and it reporting using the 40 Mhz channel width, I only see a max of 130 also.

I'm not sure why that is, but yeah...it's capable of it...just doesn't do it.

IIRC Apple limited airport card to 130Mbps @ 2.4Ghz/20Mhz, and 300Mbps @ 5.4Ghz/40Mhz to avoid blue tooth conflicts. I can't find it now on apples support pages so I may be wrong..
