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

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.

I live very close to a hotel which has multiple SSID's that keep interfering with my ability to stay connected to my router.
I've tried hard coding a static ip on the phone, adding the mac address to router, even went as far as creating a separate unhidden network just for the phone. So far, nothing has worked.
So i was thinking that maybe there's a way to have the phone ignore certain signals, lock on to a preferred one or use WiFi but turn off the scanning feature. The only problem is that I haven't been able to find any settings or Apps that will allow me to do it.
So, if anyone has any ideas or suggestions as how, or if, I can make this work, I would greatly appreciate it.
I'm using a Droid 2 Rooted with 2.3.3 and have a Netgear N750 router.
BTW - none of the computers in the house are having this issue.

So, are you saying the phone constantly tries to leave your home wifi in favor of attempting to connect to the hotel's?
Yes, unless I'm within about 5 feet of my router, the hotel's signal makes the phone keep dropping and reconnecting over and over again.
Sent from my DROID2 using XDA App
Are the hotel's hotspots not WEP secured? That is so odd. If they're unsecured hotspots go over to the hotel and tell them to get their sh*t in order. Otherwise I'm out of ideas, sorry.
No, they are secure. WPA2 as is mine. I don't connect to them. My phone just detects them, drops my connection and tries to connect to them. So that leaves me with no connection and having to use 3G.
But there may be an easier solution to this. After spending a few hours on the Netgear site, it turns out that there is a bug in their firmware that causes signal strength fluctuations. They said a new release should be available in a few weeks.
In the meantime I've changed the channel on the router to auto select which seems to be helping.
I do appreciate you taking the time to assist.
Thanks!

Glad there's at least some kind of work around, wish I was of more assistance.
Having a similar problem with a samsung galaxy sii - current internet configuration is through AT&T U-Verse with built in Wireless G router in there Gateway. tried adding a Netgear dual band N router to my network and with the netgear's 2 wifi signals on then my phone just constantly goes into scanning mode and keeps trying to connect between the 3 - things work fine with the wifi turned off in the new netgear kind of defeating the purpose of me installing it - was hoping to have the phone use one of the N signals..
Block bt openzone connection pleaseee!
Desperately need an app for this? Is it not going to be possible for a way to block certain wifi signals because I'm actually going to rip next doors BT openzone router out of the wall and get a hammer to it! My HTC desire hd is insistent on connecting to its poor signal over our excellent one and the worst part is that you can't actually access the network unless you pay BT for a user account! Grrrr.... Please help
Try to connect the network you dont want, then go to wifi management in settings. Long press on the network you dont want and hit forget network. Then your phone shouldnt automatically connect to it unless you tell it to.
for those with wifi 'broken' try to change your router settings to WPA2 personal (TKIP+AES) that seems to work for me now,
other settings 'broke' the wifi
this might be just an issue with must me and my router
*spoke too soon: still broken, it only works certain times, mostly it just spins when i try to connecto to online
the wifi icon keeps flashing a black dot... that means the wifi is NOT working right? it should be just a solid blue bars?
on wifi advanced settings, WPS Pin Entry - what is this and do i need to enter that pin on my router?
still no luck with wifi on my network after flashing back to stock 4.2 from 4.2.1
same 'broken' wifi
might be this phone's wifi hardware is incompatible with wDDRT router?
Firmware: DD-WRT v24-sp2 (10/10/09) std
my other wifi devices work perfectly fine, so im really stumped
in phones advance wifi settings it has this WPS entry - what is this and is it somehow not allowing me full wifi?
i can view playstore,, it checks and loads my gMail but it won't connect to websites
it takes so long to download and install apps from playstore, i have to hit cancel, redownload, reinstall to get it working,etc. its not 'instant' like normal 20Mbps wifi should be
ran speedtest.net app and it wont connect to any servers
if anyone has clues to why my wifi is broken, please PM me thanks
it get a blue 3 to 4 bars on wifi signal but it keeps having this 'black' dot flashing in that wifi signal bar, (what is that?)
shows connected to my wifi at 72Mbps at good strength
I found my solution: in my router I unchecked the option WMM (Wi-Fi-multimedia)-settings (2.4GHz b/g/n). After I activated it, my data speeds increased enormously. Try it & report!

My n4 will not connect to any of the WPA2 AP's around here.
I have the opposite problem. I can connect to my WPA2 router at home just fine but cannot connect to the WEP wifi at work. Well, not reliably. I've gotten connected twice, but was unable to recreate the conditions.

I had speed problems with my 5GHz band at home. Connected, but couldn't get over 1Mbps on my 30+ connection. Connected to the 2.4Ghz band and I get significantly faster speeds. Haven't had problems connecting though.

I've noticed similar behavior, seems like my 5ghz signal strength is much weaker than my 2.4ghz signal according to my n4.
So this n4 is picky about. Certain WiFi networks.configs
Sent from my Nexus 4 using xda premium
Sometimes, my N4 loses wifi connection at work. It's inconsistent. My work wifi is open but MAC filtered.
There have been 3-4 times when I noticed that it lost wifi connection. I had to turn off wifi radio and back on to reconnect.
OTOH, connection to home DD-WRT wifi router is rock solid.
Set lease time for as long as possible, it normally this is 2 weeks..

Hello, I am also having problems with WIFI. I've tried a lot of things (change the router configuration, the cellular exchange kernel, etc ...) but I could not fix this problem. Can you give any more ideas? I've even thought about buying another router but can be giving the same problem.
I used my wife's phone as a router and it works normally, but when I connect directly to the router from home and he trasfere data only for a few moments and then transferring data, although still seem the symbol of wifi connected.
I found changing a setting on the Nexus 4 seems to have remedied most of my WiFi issues. Forcing the WiFi frequency band to 2.4GHz only instead of Auto appears to have done the trick for me.
In WiFi if you select Settings and Advanced under Wi-Fi frequency band there is an option to force 5GHz or 2.4GHz with the default on Auto.

Heyho, i currently have access to my wifi as well as to my neighbors network as my wifi gets weak while i am in the garden. I feel like android isnt awitching to my neighbors wifi automatically. Only when my wifi is completely gone, android will look for a new one.
I thought about making a task with tasker which looks for another wifi as soon as the current wifi strength goes below 25%.
Or is/should android do that aleady on its own?
Thanks
In wifi -> Advanced settings there's an option to avoid poor connection. I have no idea what it actually does, but give it a try.
I did the test with my router, which supports 2 frequencies.
Assuming both networks are saved in the phone, it connect automatically to the one with better signal or look for an alternative if signal is lost.
Thats what I mean, it will connect to the other WiFi if the connection is lost. But if the connection is crippled (bad) enough to not handle a music stream, but still "availabe" it will not switch to the other WiFi eventhough that other WiFi has 100% signal strength ?
I activated the "use wlan only if good strength available".. lets see how this works
I have multiple APs in my house and the only way I've ever got it to switch is by toggling wifi off and on (or loosing the first signal completely). This is an Android issue IINM, my GS2 and my N4 both have this issue.
I tried the "do not use weak WiFi".. didnt work.

It has never worked for me either. Didn't work on my GSM GNex or with the N4.
I think it's how most WiFi clients work, otherwise if you were in the middle of 2 equal signals, it would spend more time disconnecting and reconnecting creating a DOS attack on the 2 AP's and leaving you with no data.
As for 2 home wireless routers, use the same SSID and authentication settings for both, and put one on channel 1 and the other on channel 11.
Make one a AP only (no router, no firewall, no dhcp server) and connect it to a client wired port on the first one. You can roam between them like people in large offices do.
or I try to make a tasker profile
if wifi strenght below 20% and another wifi is available with more than 30%, connect to that one.. then wait 5 minutes ?
Now what I mean by this is if I have multiple overlapping wifi networks I want to be able to select which one the phone will prioritize its connection to
Why this is important for me is at home I have my 5Ghz network and my normal network(2.5Ghz I think).The 5Ghz network wont travel as far as my other network but speeds are much better
So basically I want my phone to use the 5Ghz network until its no longer available.Another example of how I want to use this is at work I have access to my private wifi around my desk and corp wifi around the office
The corp wifi blocks access to certain content so by prioritizing my private wifi the phone would stay connected to it unless it loses coverage and then it would switch to the corp wifi and vice versa
I tried a bunch of apps I could find and none seem to work too well. I know some versions of CM had something like this but cant seem to find anyway to do this properly on stock ROMs which I figure would be a good feature
Any suggestions would be welcome
My case the only way I have found to solve that was enabling roaming assistant on my routers (RT-AC88U's) to help my devices switch to stronger signals, and smart connect to switch from 5ghz to 2.4ghz and viceversa when bandwith on that band is saturated.

Tried the app again to see if I missed something and it pretty much has nothing from what im looking for. There is no option to prioritize specific SSID. You can prioritize 5Ghz or setup specific signal thresholds but what im talking about is an app that will prioritize SSID
So for example if I have WIFI 1 and WIFI 2 both have great signal but I prefer WIFI 1 unless it has no service then and only then it will goto WIFI 2. Once I go back in the coverage area for WIFI 1 it switches back
Found this app and so far so good.
https://play.google.com/store/apps/details?id=app.com.superwifi&rdid=app.com.superwifi
It has the option to prioritize by SSID
Will test a little longer
This also seems very promising

You know Tasker? With the autotools plugin you might be able to do this. You could make it search for ssid and if xx ssid is available, connect to it. I don't have time for more in depth before the day after tomorrow, but quote me if you need help.

Thanks but mainly looking for SSID filter vs signal or 5Ghz.
You can have different SSID for 5Ghz vs regular which is what I do at home but at work 5Ghz isnt available to I mainly need to prioritize one SSID over another unless its not available

Eh . I'm going to buy AC88U later this month. I wanna know. So. I know that if you enable roaming assistant on 5ghz. It'll switch your phone to 2.4 when the RSSI match the settings. But the thing I don't know is. If we can do the same for 2.4ghz. so when it reaches how much high strength it'll disconnect it. So making the client connect to the 5ghz. Well I know smartconnect can do it. But smartconnect disables the channel selection. Thanks [emoji4]
