Hello everyone,
I am running a TP Link TL-WR1043N which (as TP Link says is a) 802.11n router working on 2.4Ghz (no support for 5Ghz). I am running it with flashed OpenWRT.
While using option to pick 40Mhz, I see my Mac only gets 20Mhz to use and speed is always 130Mbps. There's no other SSID nearby and I am sitting next to router for testing.
This brings me to question - Has anyone successfully used 40Mhz with 2.4Ghz on 802.11n standard with Apple Macbook? I wonder if it's limitation on the chipset or something else.
Everything that I've seen/experienced says that Apple devices won't use 40mhz channels with 2.4 due to the overlapping bands/lack of good separation between channels. However, I'm not sure if this specifically applies to just the Airport APs like the Extreme, or to the laptops as well, as I use AE's at home, and the Unifi APs I do have in service all have 20mhz channels only set on them to avoid issues. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
