Is there any method to force use 5GHz WiFi only in custom ROMs? MIUI has an option to manually select WiFi band to either "2.4", "5" or "automatic". But it seems that there is no such option in LineageOS and Nitrogen OS and they use something like "automatic" as default setting which prefers 5 GHz over 2.4 GHz if the network uses same SSID for both the bands.
Most of the times it works good. But when it switches to 2.4 randomly, the speed becomes considerably slow. My university uses the same SSID (and I can't modify router settings of course) so it becomes a problem when it switches to 2.4 GHz band.
Is it possible to do something from terminal or via root to use only one band?

I was able to connect to the 5ghz channel with galaxy s2 I9100, but I can't do this anymore, I didn't change anything, it was sudden. It's weird because the phone connects perfectly to the 2.4ghz band of the router, I am using a dual band linksys E2500, I try to modify some settings, changed 802.11a to 802.11n, tried all the channels, changed 20mhz to 40mhz. Can anyone help me?

Try to switch the selected wifi band in your phone in:
Settings > WIFI > press the options button "the left LED button" > advanced > wifi frequency band
After I selected 5Ghz only, the option to select the wifi frequency band is no longer there?? Help!!
These are the default options which are supposed to be available :
Network notification: By default, when Wi-Fi is on, you receive notifications in the Status bar when your device detects an open Wi-Fi network. Uncheck this option to turn off notifications
Avoid poor connections: Check to automatically avoid using networks with a low-quality or intermittent Internet connection. <- this one as well!
Keep Wi-Fi during sleep: To conserve mobile data usage, your device stays connected to Wi-Fi when the screen goes to sleep.
Touch this option to change this default behavior: either to stay connected to Wi-Fi only when the device is connected to a charger (when battery life isn't a problem), or never to
Stay connected to Wi-Fi during sleep. The latter choice is likely to increase mobile data usage. You may want to revisit this setting if you receive a notification that you're approaching your specified mobile data limit.
Wi-Fi frequency band: Specify Automatic, 5 GHz, or 2.4 GHz frequency bands <-- this option is missing
Any ideas? Thanks!
Also, it's not just my default 2.4GHz band missing, even the neighbors. There were more than 10 when I scanned for them previously
Same problem here
I have the same problem on my Galaxy SIII... I chose to disable the 5Ghz band (2.4 only) in an attempt to suss out the problems with my phones wifi connectivity. I duly forgot about the setting until recently.
Between then and now - there was an update to my phone (which I did apply) - and now the advanced menu for Wifi does not contain an option to choose the Wifi Frequency Band... I've tried looking for 3rd party tools that allow you to set this - but haven't found any yet...
I'm on Android v. 4.0.4 with T-Mobile. Does anyone know how to set the frequency band back to Auto?
Much appreciated!!

Even I didn't find the option. Which version was this present in? I'm on GB.

Why did samsung remove this very important feature (Wi-Fi Frequency Band) with this new update?
How am I supposed to chose between Auto, 2.4GH and 5GH connection now?
Will you put it back?
Any OAT to fix the problem?
CAN ANYONE AT SAMSUNG EXPLAIN THIS?
I HAVE CALLED AND CHATED W/ SAMSUNG SUPPORT, BUT NOBODY CAN GIVE ANY INFO.
Ditto
I am suffering from exactly the same issue on my Galaxy SII. I had it set to 2.4ghz only under ICS, and then flashed the latest leaked JB update. Now am missing the advanced options as per the OP.
A fix or app able to adjust these settings would be fantastic!

Phone is not rooted and I want to stay it that way. Any other suggestions?
Have u guy's tried 'Wifi Connection Manager' from stores
https://play.google.com/store/apps/details?id=com.roamingsoft.manager&hl=en
I just tried and it's a no go, still can't find 5ghz networks.
Have you done a factory reset? If not, go to your recovery and delete cache and data. There are no other options if you don't root that comes to my mind.

Twice, but it didn't help.
I was quite surprised to see there is no configuration to choose 2.4ghz or 5ghz, on top of this I cant find a way to view the current band in use. Why make a dual band phone where 5ghz is effectively disabled?
I then read that the option used to exist in 4.0 but was removed in 4.1 and someone made this app.
http://forum.xda-developers.com/showthread.php?t=1891970
Now this app works, I can now use 5ghz which more than doubles my wireless speed, great right?
Well its ok but it resets to 2.4ghz everytime wifi is turned on again, so the setting doesnt stick. So basically everytime I use wifi I have to open the app and select 5ghz. Even the app itself doesnt report what band is in use, it just allows you to select the band to use.
Is there a way to (a) easily see what band is in use and (b) set 5ghz as the default.
Thread moved to porper forum.
I have tried giving 5ghz its own wireless ssid so seperate from 2.4ghz but then its much slower. It seems when the ssid is shared, it uses some kind of parallel mode where both can be used at the same time.
So what I want is when 2.4ghz and 5ghz share the same ssid and the phone connects to 5ghz. (preferably via an option on the phone).
Hi,
Recently i needed to user wifi for internet on my HTC One VX, if i enable wifi and scan, my phone does not show any 2.4 ghz wifi networks.

anybody can help me ?

Hi,
I try to connect my z2 tablet to 2 different routers which deliver a "300Mbps" signal (150mbps in fact, verified with a PC).
The maximum speed connection is limited to 75mbps on the tablet (which is very close from the router).
We can see : "Wi-Fi 802.11 a/b/g/n/ac, Wi-Fi Direct, dual-band, DLNA, Wi-Fi hotspot" in the specifications, is there something that i don't understand ?
Thanks

I have the same issue with mine. I haven't tried changing any router channels or settings yet. Using my galaxy s5 and Z2 tablet from the same location I get around 270mbps on the s5 and only 75 on the Z2.
Dual-band means: 2.4 GHz as well as 5Ghz Wifi. (Either / or, not at the same time.)
In any case the Wifi is restricted to 150 mbps.
Go into your router settings and look for a setting called "HT 20/40 Coexistence" and disable it (in dlink routers it's in Advanced > Advanced wireless). This worked for me when I had a similar issue.

I've tried before and it's not the solution. My wifi network is on the 40mhz frequency and i can have 150 mbps on a pc but still 75mbps on with the z2.
Actually now I just tested my z2 tablet's wifi speed, and it doesn't seem to go above 56 Mb/s (link speed for the connection in wifi settings is rated at 72 Mb/s), on my PC I reach my ISP's advertised 120 Mb/s. Odd stuff.
I found out that the tablet is unable to get above 72mbps link speed on a 2.4 GHz signal. When using a 5 GHz signal, the link speed leaps to 135 mbps (with a floor/ceiling between the access point and tablet). Maybe for some reason the tablet is unable to use the 40 MHz channel with 2.4 GHz?
