Airport Extreme, one SSID question

[bodean]

I have my 2.4 and 5.0ghz on one SSID, and the channels as Automatic.

When I have this setup, my iMac, which is 14-18 feet from the router, connect to the 2.4ghz with signal (dBm) showing -36

The 5.0ghz is on channel 48/42, and signal -47.

Now if I set the channel to manual for 5.0ghz, and put channel 48, the iMac defaults to the 5.0ghz.

Any reason for this behavior? Thought being this close to the router, 5.0ghz would take the priority. Maybe @sfx2000 could answer this?

because you are running the router in what i consider the worst way ssid wise there is no way to know why its connecting the way it is apart from the rssi level and the 2.4 gig being far better than the 5 gig rssi level , so your client just connects to the strongest signal

reality you should set manually both the 2.4 and 5 gig channels and use different ssid names so your client can choose which band it connects to depending on its place in the remembered ssid list

if the extreme had band steering and or smart connect it would prob be ok but many have disabled smart connect as well and prefer different ssid names

I've always read that with Apple products/routers, DEFAULT settings works best.

Which iMac model, what OS?

Which Airport and what version of Airport Utility are you using?

Generally it should work, but I've seen odd things - AC models should use Airport Util 6.x, they're seen with 5.6, but don't use it - you'll get into trouble like this...

Also see in your .sig that you have an Asus RT-AC3100 - is that part of your Airport network?

Go into the network settings, disable wifi temporarily - clean out the old profiles, and reboot...

Once up and running, go ahead and log back into WiFi...
