I was wondering, is it possible to "disable" WiFi scanning once connected to a preferred network? I'm just guessing but does it use so little memory/battery to continually scan every few seconds that nobody has bothered to develop a script or app that allows this to be done?
I had a quick search on Google and the forums here but yielded little to go on.
I'm using a custom ROM atm based on Froyo 2.2.1.
Any help would be ideal. Thanks!
depending on your phone,cant you uncheck "notify me when an open network is available"?

Unchecking this doesn't stop it from scanning, it just stops it from notifying you of an open network. It will still scan around.
I'm guessing the answer is no then?
Not to worry. Thanks.

Once you're connected to a network it does not scan for new networks unless you're on the networks screen and then it will scan for them. Close the screen and it stops scanning.

I would argue that. Phones differ for sure, but mine (Eris) scans for networks and puts an icon in the status bar showing available networks if I leave wi-fi turned on. If I then open the networks screen it will show me all available networks, locked and open, but it scans regardless. It does use battery power, but a relatively small amount.

It does scan, but not constantly. Something like every few minutes or so. Maybe it's just the ROM I'm running that does this though.
Yea, my phone notifies me of available networks within range, whether on the Wi-Fi screen or not.
While I appreciate the battery/memory usage may be minimal, with the aim of optimizing my phone, an app that could disable/enable Wi-Fi scanning would be great. Am I the only person who thinks this?! Lol.

I agree. I only use wifi when I'm at home. I also use Green Power, and that will disable wifi if 3g is enabled. When connected to wifi my ROM will still scan for new networks every few minutes. I'd like a way to completely disable wifi scanning.
@Davey Boy
I too wonder about this. Like you, when on the wifi settings page it seems to scan every 12 seconds or so even though I am connected to my home network. People have said that it only does this when in that particular screen but how do they know this?
I would like to think they are right but is there any way to prove it?
Please let me know if you get anywhere with this.
Yea unfortuately all wifi connections scan due to ip leases. Depending on the router after a certain amount of time in dhcp mode your ip address expires and then is re-issued. Another reason the wifi card pings the router to ensure the connection is still alive. So honestly to stay connected the wifi needs to scan.

Pinging the router every few minutes is different from scanning for networks. Also, lease time is normally 24+ hours, so there is no need to constantly scan for networks or ping the router.

I too am wondering why we can't specify a prefered network and not bother scanning for others! I also have to kill wi-fi sharing service (with android optimizer) everytime I enable wi-fi
I have same problem after upgrading to 2.3 Wi-Fi shown as it is Active, but it is turning off and on and scaning and off again all times
hellllllllllllllllllllllllllllllllllllllllllllllllllllllllp hellllllllllllllllllllllllllllllp
heeeeeeeeeeelp
helppppppppppppppppppp

sorry...........
Old topic but still interested. Any workaround found?
You can change the speed to a ridiculous amount of time. In your build.prop WiFi.supplicant.scan.interval should be set to a number of seconds. It is not advised to say change it to 24000000000000. Or something insane because if u lose signal it won't be reconnecting for you until that time is up.

Hi all,
My brand new Nexus 4 doesn't seem to hold a wi-fi connection with my Netgear WNDR3700v2. I've set up a 2.4 Ghz network connection on channel 1 with an AES security. Added the Nexus 4 with a static ip. It will hold the connection for maybe an 20-30 minutes, but if I don't use the phone for a while (like an hour), the wi-fi connection will drop as soon as I press the power-button. The wi-fi icon just disappears and connects after a few seconds, or it turns from blue to grey, disappears and reconnects.
It's really irritating. My Gnex (Android 4.2) en my girlfriends Gnex (CM 10) both have a stable wi-fi connection with the router, all the time. They have the same settings and my Nexus 4 has, just as my old Gnex, activated the wi-fi optimization setting and disabled avoid poor connections. All phones have keep wi-fi on during sleep at always.
I was wondering if someone has similar problems and maybe have an idea what could be the problem here. Thanks!
is sounds like the same issue on the nexus 7

Check your wifi sleep policy in settings. If its set to "never" it will drop when phone is in deep sleep. Try setting it to "always" and see if that helps.

Thanks, but my posts says "All phones have keep wi-fi on during sleep at always."
I rolled back my router firmware to V1.0.0.12 and everything seems to be ok now. Going to run a few more tests.

Woops my bad.
Hi guys, I'm having problems with my WiFi. My WiFi is randomly disconnecting. When I go to WiFi settings it only shows me 1 network (the 1 I'm connected to). It says me the network is saved and some security details. When I turn WiFi off and on it shows me all the networks in my region again and says I'm connected.
This problem seems to appear more frequently in the evening.

Using static IP may solve your disconnecting problem. But I haven't faecd the rest.

Get WiFi Analyzer and look for overlapping APs in the signal strength per channel view (the one with the 'hills'). Chances are this is your problem. If possible change your AP to a less busy channel. Also walk and pause through your home with it to 'bad' spots. I have more disturbing APs from neighbours in one side of my house compared to another.

This is good advice. Find the strongest channel and use it by changing the channel in the router settings.

My dad did this already. We have 2 modems to extend range, the 2nd one automatically connects when coming close. Is it possible that my room (where i experience the problem a lot) is at the border of connecting with the 2nd one?

Signal is main issue, why not try some signal enhancing adopters or maybe problem is battery apps like juicedefender which automatically disconnects WiFi..
I have had my Galaxy for about 9 months now. Recently it has started to disconnect and reconnect to wifi constantly. It does this with my home wifi as well as guest, friends, establishments wifi. It will say "connected to xxxxx wifi" and then a few seconds later drop back to 4G and then a few seconds later say it's connected again. It does this over and over and constantly drains my battery now. Any ideas?

Which version of Android do you use? KitKat / Lollipop?
What about smart switch option in wifi menu? Is it on? If yes, try turn it off.
I've had this problem since Monday?
Thought it was my Router , but it happens across many other wifi connections?
Ive tried all the fixes on other sites but still occurring Could be the Lollipop Update?

So @ monday you have updated your phone?
Turn off Smart network switching in settings in WiFi section.
Dropping WiFi is common issue of lollipop. First recommended thing is wiping your phone completely via stock recovery.
Smart Network Switch is likely the cause -disable it

This Worked , Can't believe it was something so simple!
All the other fixes online are about the S4-S3 and its going into the WiFi Setting to reset and disable other functions!
Thanks m8ty
You will not have had the same problem but the wifi signal in my mi9 t is disconnected every so often. The further I am from the network the more it does but even when I am close, every 3 or 4 minutes it disconnects itself, when I am further away every 30 or 40 seconds. I also have a redmi note 4 and it does not have that problem and a mobile phone of another brand and does not disconnect from the wifi. However, with my mi9 t, you can have a decent connection that after 40 seconds loses the network signal and I have to press the wifi icon every so often and connect to the network again. Does anyone have a solution?

If you're on the stock ROM, you could try a factory reset.

Me with wifi disconnected problem , which is 2.4/5GHz hybrid access point. It seems to be the bug of my router, not the phone.
Connection to access point that has only 2.4GHz or 5GHz is no problem.

I have the problem with both access: Only 2,4 and 2,4/5 GHz. Other phones not have the same problem so, is my phone, not my router
