Hi
I have Wireless internet at home with 2 available access points, for some strange reason, my Hero (T-Mobile) insists on connecting to the weaker signal, even if I try changing it to connect to the stronger signal, it re-connects to the weaker signal then disconnects and connects back to the stronger signal, I have reset the phone to factory default as I had other issues with it but this does not seem have resolved the wifi issue, any ideas?
p.s. if we can avoid the "use the search button" that would be good
T-Mobile G2 Touch
Firmware 1.5
Baseband Version: 63.18.55.06FU_6.35.07.08
Build: 2.73.110.26 CL#69351
Software Version: 1.0.0.A6288
I think there may be apps in the market to help this issue.
Search the market for Wifi and see what you get.
Sorry can't be more specific as I don't have this problem myself.
I have tried that before, most of the apps seem to be either a wifi switch (on/of) or a wifi scanner,
thanks for the response
The problem could be wireless interference or other issues with the wifi router. The stronger signal (I'm assuming this is your own wireless router) may drop its signal, if only for an instant, due to wireless interference or other issues, causing the phone to switch to a more stable, albeit weaker, signal.
The first thing I would do is try changing the wireless channel on the router. 99% of routers default to channel 6. If there are several wifi signals in your area, open or secured, there's a good chance most of them are on channel 6. I'd suggest channel 11 myself, but you can try any of them.
If changing the channel doesn't work, you can try adjusting the more advanced settings, such as setting it to 11g-only instead of b/g. Other settings you could adjust are:
- DTIM Interval
- Beacon interval
- CTS protection
- RTS threshold
- Frame burst
- Preamble type
- Authentication type
Of those advanced settings, I would go for preamble type first, as it's the safest to play around with if you don't know what you're doing. As far as the other advanced settings, I'd do a google search to figure out what they mean before messing with them too much. I could explain them all, but I'm not here to write an essay
Note: Not all routers allow you to change all of these settings. Particularly cheaper routers will have far fewer advanced options than what I've listed here.
Hope this helps!
thanks for that, ill try changing it to channel 11 and try again, when i dop a wifi scan, it picks up about 7-8 different secudred AP's so it may well be the interference,
thanks muchly
Following on from my investigations on why the SGS2 takes *so" long to re-establish a WiFi connection, it now seems part of the problem is a major delay in obtaining an IP address.
In another thread (I forget which one) it was suggested that slow WiFi could be caused by a router not being able to cope with 802.11b, g & n traffic at the same time, which got me thinking - what if I disable the n part of the WiFi on the phone to revert it to 802.11g - would this make acquisition time on an older router faster?
So - does anyone know which file / script etc. could be altered to keep WiFi enabled, but ONLY at 802.11g; not utilising 802.11n?

Just a guess, but is likely a build.prop tweak
Is this a frequent problem ? Has never happend here

As I've said in my post on the general forum, I get a horrible delay every time I ask the phone to connect WiFi.
I've got the WiFi sleep policy set to "when screen turns off" to save battery power; and using the same router as on my SGS (hell, i can sit the phones next to each other to try this) I get the following:
Waking the SGS up from a sleep results in a delay of 1 or 2 seconds before WiFi connects.
Doing the same with the SGS2 results in a delay of up to 1 minute before WiFi will connect. (sometimes it can be seen to give up trying to acquire an IP address, then try again)
...so yes, may be a router issue, but clearly there's something different between the 2.3.3. on the SGS versus the 2.3.3 on the SGS2 as well.
You could just disable n mode on your router if you think mixed mode is slowing it down. Most new routers will let you choose which wifi modes to broadcast via their web interface. The best option would be to only use n if all your devices support n.

Router only supports g. I'm suspecting the phone looks to n first, hence my interest in disabling it.

quick side note, wifi sleep policy set to NEVER saves you much more battery power because when it switches over to 3g, 3g uses way more power than just leaving it on wifi. counter intuitive but true.
Have you tried hard coding an IP address on the S2?
And by Hard coding, he means manually setting a Static IP address and now allowing the DHCP to provide you an IP address each time. Although the IP will most likely be the same while using DHCP, it has to request and authenticate each time. Setting a Static IP address eliminates the process of "Asking" for a IP address each time.
when the phone scans and finds the ssid, as part of that scan it checks if the router supports b/g/n then will try to connect at the highest speed. If the router isnt n compatible it wont even try.
I don't want to give the phone a static IP as I regularly visit three or four different wireless networks and they don't all use the same IP range.
I do know how DHCP works, this isn't a newbie question.
It seems definite now, watching the phone, that it tries to connect once (presumably on n), fails, then re-connects (quickly) on g.
Of course, I'll be changing the router eventually; I'm just interested in what's going on first

Understand about leaving it set for DHCP. Trying a fixed IP as a test may tell you if DHCP is part of the delay. If the b/g/n search is that slow it would be useful if it could be configured more precisely.
Have you tried it using another router using only g? If n is available it connects quickly? Seems like others would have mentioned this if it is something with the phone as g-only networks are still common.
I too am interested in disabling 802.11n. wpa_supplicant keeps hanging on some wifi networks and I suspect it may be because of n.
When i downloading torrents using my android phone over the WiFi, its connection lost several times. My phone WiFi policy is "Keep WI-Fi on during sleep" as "Always". I use "Ttorrent" app client. Most of the time Ttorrent display "No suitable network" error. If i turn on the screen, problem not fix.
I have android 4.0.3 ROM and i connected my phone into my ADSL router, not a public.
Are there any solution for me?
Thanks!
Did you rule out the signal strength and wifi network quality? It might just be that the connection is flaky. One way to test is just sitting close to the access point or.. to change it to a different channel (when you suspect interference from neighbor routers is the issue)

Thanks friend your reply!
If I move my phone close to the router, its not fix. Also its possible affect, my neighbors Wi-Fi connections (because of the distance of neighbor houses, to my place). Is it a effect of my router settings?

Is there an option in your client to lower the maximum number of connections? That's a recommendation from the developers of adownloader, which is what I use
I am having the same problem.
I've tried so many things, on the phone and router.
Nothing has solved it.
I've adjusted a lot of settings on the router which have made no difference, I've used different types of security, wep, wpa, wpa2, no security at all. Static ip, changed dhcp lease times etc
On the phone I've tried setting a static ip, flashing different kernels, using different torrent clients, lowering number of global connections to 1 etc
I've also tried a few apps from the play store, wifi fix, wifi static etc
The wifi will just randomly disconnect when I download any torrent, there is no pattern to it but I can't download any torrent without disconnecting.
I would love to know a fix.
I'm using a galaxy s3
One thing I want to try is a different router to rule out whether the problem is the router side or the phone side.
At the minute I have no idea what is causing the issue.
I don't get disconnected when browsing the web etc on my phone.
If I use my pc or laptop to download torrents I don't get disconneted.
Ok I've finally worked out why I was getting drop outs.
For some reason when I use wpa2 with aes ecryption I get disconnected when downloading torrents.
When I use wpa and tkip I get no disconnects at all.
It's not a good solution as I get slower speeds using wpa and tkip but at least I don't get disconnected.
I wonder if this will be fixed?
This is an ICS bug. No matter what you have your wi-fi sleep policy set to, when the screen goes off the performance drops drastically. Download the Wi-Fi High Performance Widget from the market. When tap to enable the widget, your wi-fi will run at 100% performance no matter your screen state.
This isn't a sleep issue though. I have wifi set to always on keep wifi on during sleep.
Even the op said he tried leaving the screen on.
I set screen timeout to 10 minutes so I can monitor the application and also set screen on within adownloader and I get disconnected.
The only fix for me is using wpa and tkip encryption.
As soon as I use wpa2 and aes encryption I get disconnections when downloading.

Well, probably a hardware issue. I have no issues using the same wifi configuration and downloading torrents. And like I said..it really doesn't matter if you have keep wi-fi on during sleep checked. That doesn't matter at all. The performance will degrade so much when the phone is asleep that you might as well have it turned off. No, your wi-fi won't sleep, but it won't be running anywhere near its top performance, which is what the widget is for.
Wow. I have been trying to solve the same problem for last 2 weeks. upgraded windows drivers, router firmware, tweaked utorrent settings and whatnot. finally after reading your answer i changed my wifi authentication from wpa2+aes to wpa+TKIP and WOW. it worked. my wifi is not dropping anymore. I dont why WPA2+AES should cause this problem. BUt this tweak in authentication has finally worked for me.
(April 24th, 2015) After searching for a solution to my wifi dropping I collected a comprehensive list that has helped in one way or another. After seeing similar issues on S5 phones it appears this isn't solely a S6 problem. If you find or have used a method not on the list please report and I'll add it.
Possible fixes for Galaxy S6 WiFi problems:
Factory Reset
“Forgetting” your Wifi Network and Reconnecting
Settings ->Wi-Fi. Hit menu then Advanced. Make sure Keep Wi-Fi on is set to Always.
Settings, more networks, mobile network, uncheck Connection Optimizer
Under the Wi-Fi settings uncheck "Smart Network Switch"
Resetting the Modem/Router
Settings→wifi→WPS Button and same button on modem/router to 'lock on'
Switching from DHCP to Static Connection on Phone
Connect to your router's 2.4GHz band instead of 5GHz
Install a DNS changer app, select primary/secondary servers to Google or yandex.
Changing the Router Bandwidth Settings
Changing the Router’s Broadcast Channel
Adjusting the router security settings to WPA or WPA2
Enable WMM in your router settings
Disable IPV6 in your router settings
Calling your ISP and upgrading to a Higher Bandwidth/Speed
Wipe phone cache
1) Power off the Samsung Galaxy S6
2) Hold the power off, volume up and the home button all at the same time
3) After some seconds, the Galaxy S6 will vibrate once and the recovery mode is started
4) Search for the entry called “wipe cache partition” and start it
5) After a few minutes the process is complete and you can restart the Galaxy S6 with “reboot system now”
Disable phone's wifi power saving mode
1) Open your phone dialer
2) Enter *#0011#
3) Select more (top right)
4) Select WiFi
5) Turn off WiFi power save mode(enabled by default)
6) Exit and hopefully your WiFi connectivity issues will no longer be a problem

(April 11th, 2015) Anyone experiencing wifi dropping out? It seems to happen when I require it, ie browsing themes or downloading apps. It will lose wifi and the lte icon appears and the screen freezes temporarily until wifi is restored. Last night this happened like 6 times one after another which wasd very annoying.
WiFi working petectly fine connected to my as router
Sent from my Samsung Galaxy s6 Edge
Yes, I am having the same issue. WiFi drops out, screen freezes and then WiFi comes back and everything works again :/
It seems to have settled down a little now, only seems to happen when there is quite a bit of WiFi activity.
It kept happening to me while I was downloading a GPS map and also when syncing Spotify.
I am connected to a 5GHz AC router, what sort of connection are you using?
Yes,
My device has also done this also around 4 - 5 times and i was thinking could it be Smart Network Switch which is on for me.
i have also noticed the wi-fi has dropped out for when the phone is asleep and i awake it.

I don't have Smart Network Switch enabled, so it isn't that for me.
My WiFi always stays connected through sleep though.
What sort of connection are you on? G/N/AC/2.4GHz/5GHz?

I'm going to a friend's house later and will see if the same issues occur on his network.
I'll be able to do some tests at work tomorrow.
I haven't had it happen today at all :/
I downloaded Angry Birds Space 3 times this morning and no wifi drops. I was on the road and something locked up where I couldn't swipe between home screens or open the app drawer, noted I had wifi on even though I was in the car outside of a network. Didn't get to test the wifi at my friend's house but just tried downloading AB again and wifi dropped out.
This is getting annoying. Thinking I might see about going in to BB to exchange, this isn't a glitch I can live with or risk being a hardware defect. I plan on contacting Samsung to make sure they make a note, hopefully they are aware of this.
Galaxy S6 (not the edge.) Same issue. Wifi drops. Music stutters. Have to turn wifi off and back on to reconnect. Using Apple airport express.
Same thing here with galaxy s6 edge. Wifi keeps dropping out. Web pages too slow to load.
Will return the phone tomorrow.

Jesus, these phones are gitchy as all hell. I get mine Thursday. Going to mess around with it for a week and if I keep having these same problems I'm just going to return it and move to something else. I've never seen soo many issues with a new phone in both software and hardware.
If anyone can test other wifi networks or exchange phones, please report back with results.

I tried a few of those, others aren't necessary. I did 2 factory resets and the wifi was fine downloading 54 apps but dropped at the last one, and lasted all 55 but dropped later. I'm going in for an exchange tomorrow unless someone posts a magic fix.
The Recomhub website helped me fix my WiFi dropping problem. Thanks for the link, it really solved my issues!
5GHz Network
I've been testing this, because it is really annoying me now.
When I am connected to my 5GHz AC Network at home it drops out and freezes the phone quite a bit.
When I am connected to my 2.4GHz N Network at home, there is never an issue. Wireless actually seems to work better on this network.
So, for me at least, this problem is being caused by the 5GHz networks and switching back to 2.4GHz makes the problem go away.
This is an annoying bug, I have emailed Samsung about it, let's see if anyone replies.
My router is Simultaneous Dual-Band N (2.4 & 5 GHz) so I wonder if that is causing my issues. No idea how to remedy it at the moment.

Mine is too, but I have the ability in the router to separate the two networks, so my 5GHz network has a different SSID than the 2.4GHz one.
I've been connected to the 2.4GHz network all of tonight and done quite a bit of downloading to test it and it hasn't dropped out once, yet on 5GHz it would have done it at least twice already by now.
I cannot replicate this problem at work on the 5GHz Network. It must be something to do with the channels they are set at.
I will try and change some channels on the work network, see if I can get it the same as at home and then test again.
I have a call booked with Samsung who are going to remote my phone, hopefully they can pinpoint something
I can't even connect to my home's 5GHz, the 2.4GHx is what I'm testing.
I went to BB Wednesday and the Samsung rep wasn't aware of any wifi issue or remedies beyond what is mentioned in this thread. Of course I didn't lose wifi the brief time on their wifi network so the guy didn't know what to say other than contact Samsung support.
I tested this at my house last night.
64GB White Edge AT&T on 5.0.2
E3000 router with DDWRT
N700 Router with DDWRT
Both dual band, both running 2.4 and 5 Ghz
Both set to 40 channel width
Both with channels spanned correctly for no overlapping
Never lost connection while downloading and updating all apps throughout about 2 hours of use. Speeds saturated my broadband link (50Mbits/Sec) and never had a problem. However, I don't know about battery drain as I'm brand new and still letting everything settle for another few days before commenting/testing.
I'm using a Pixel 2, with the latest updates, and I'm constantly getting issues when roaming WiFi within my house.
I have 3 AP's from Mikrotik, properly configured, and I don't have no issues at all with other devices like my iPad or Surface Pro/Book, etc.
But once in a while, my Pixel get's stuck in the state "Connected, No Internet" and it keeps retrying... until after a couple of minutes (5 or more) it properly connects...
Is there a way to disable this?
Another thing that I've noticed is that often the device only connects to the WiFi (switching from LTE) only when I unlock it or wake up the device. Have anyone noticed something similar with Pixel 2 or other devices? Any recommendations?
Cheers,

Hey, I don't own a Pixel but a Note9 but would certainly try to help you.
Do you have 2.4 Ghz router or do you connect to a 5 GHz SSID? If yes to the former, have you tested different channels. Interference in some rare cases can cause unstable internet. You can use the Wifi Analyzer app on the play store to test.
I had fixed a similar problem on my older S7e by assigning static IP to it. Try this as well. Static IP can be configured on your router as well as on your device itself.
Android do has options to set Wifi Aggressiveness. See if you have set Wifi Aggressive Mode (it connects to Mobile data even if Wifi is slightly unstable). There's also two more options (in developer options) that are worth checking: Wifi safe mode and Wifi power saving mode.
I understand that these options are hard to find and that's what made me initiate this guide. Do have a look.

Hi,
Thanks for the reply. My WiFi is properly tuned. No channel overlapping. I'm using 5Ghz band only, same SSID and different channels, and bespoke antenna gains to reduce signal overlap.
None of those options are available in Google Pixel 2. No Power Save Mode and no Safe Mode. Only the option to have Mobile connectivity in background for Fast Switching.
My ask is more towards on how to disable the connectivity check from Android. Nothing else. I know I have Internet access. I know my AP's are all working properly. It's just something with Android...
