mac filtering not disabling 2.4ghz

[karenmcd]

I'm using wifi analyzer software on my android phone to find the mac addresses of a wireless access point im connecting my gargoyle router to, and help me troubleshoot this.

There's 3 mac addresses from the router AP im accessing. 1 mac address is assigned to channel 36, and is a 2.4ghz AP @ 97% strength and the other 2 mac addresses appear to be on channels 44 and 144 both about 85% strength AP. They are all on the same physical device. It's a Telus rented router and modem combination i don't have physical access to. My friend is letting me borrow their internet for the next couple months while im moving.

you can probably see where this is going? I have disabled 2.4 ghz operation in the "wireless mode" section, and turned on "deny only mac address list" where i denied the mac address of the AP that has 2.4ghz connection broadcasting... but my gargoyle router keeps dropping the 5 ghz connection, even after i manually select the ones on channels 44 or 144 to connect to and share, in favour of the slightly stronger signal of the 2.4ghz that is significantly slower for my 7 devices to share )o: (2 phones, tablet, laptop, tv, console and pc)

this is super frustrating because it's killing my connection speed significantly (like 9x slower), due to QoS i have no control over, throttling my connection even more.

is there anyway for me to completely disable all 2.4ghz functionality of my gargoyle router? (linksys wrt1900acs) I'm able to ssh into it and am relatively familiar with the linux terminal. I have custom roms on all my android devices, jailbreak my gaming consoles/webos TV, and have been generally using linux since Mandrake, CentOS 4 and Knoppix 3.6... so if it's through the terminal emulator that's fine.

any help or suggestions are welcomed (o:

The MAC black/white list only controls what can connect your signal, not what you’re connecting to.
If you want to lock your connection to a specific wifi network (particularly when there are multiple available with the same name) you want to use the “bssid” option.
Identify the MAC address of the wifi network you want to lock on to, then edit your /etc/config/wireless and add
option bssid 'aa:bb:cc:dd:ee:ff'
To the same section that has your STA mode connection.

Restart the wifi (using the “wifi” command) and it should stay attached to the one you want.

Another option if you would prefer GUI is the STA Manager plugin.
While it is designed to let you connect to multiple networks, there’s no problem using it with only a single network configured. This interface exposes BSSID options for you.
