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.
Hi,
I've tried disabling WIFI powermode (which I do everytime I reboot), but my wifi seems pretty flaky. Speed is great, but it sometimes disconnects (not THAT often).
I have two APs, both set on same channel / SSIDs etc. Looking at wifi analyzer, it seems like the phone doesn't really handle switching between APs very well.
Is there a kernel or mod that would help with that? Or perhaps a better way to set my APs? (DD-WRT and Tomato, all 2.4G). Should I try the modems or is that just for cell network performance?
Especially annoying when using Talkatone or Skype to phone someone and then it drops in the middle of a call.
Thank you!
Setting to AP's within range of each other to the same frequency is asking for trouble.
Having them both broadcast the same SSID more so.
The kernel handles Wifi-related stuff, modem is only for cell communication.
Wifi has no handover protocol such as 2G/3G/4G does, so you'll stay connected to an AP until you loose the connection and then reconnect through the whole connection protocol (including Handshake, Authentication, DHCP, ...) on the next one. So it's a pretty bad protocol for moving around with a constant data stream.
I was under the impression I HAD to have them use the same SSID since this AP is there to extend the range of my home wifi (as per: dd-wrt WAP website I can't post link to since I'm a noob), I'll try setting them to channels 1&11 see if it gets better...
I had issues at work. But not at home.
Today I told it to forget my B/G radio and to connect to the N radio. No disconnects, none..
No changes made to the phone at all..
Hello everyone,
I'm a longtime lurker of XDA ever since I switched from my Palm Pre (RIP) to an HTC Evo 3D. I created an account finally to post this question and I'm hoping someone can help because I am at the end of my rope.
My Nexus 9 has a wifi issue that cripples my entire network. First, I'll give you the details of my configuration and the problems I'm running into:
Running an ASUS RT-AC66R on Centurylink DSL. I have tried both the 2.4 and 5GHz bands. I have tried multiple channels per band with no effect on the issues listed below. The 5GHz band is currently disabled.
Unless I am am running the factory image that came with the N9, my wifi connection will almost completely dry up across every device on the network when the N9 is connected. As far as I know, this only happens on my home network.
Restoring the N9 to factory settings - which I have now done twice since purchasing it on Nov 3 - eliminates this problem almost entirely until I install the OTA update. This problem happened with both the day one patch and persists in the recent update to 5.0.1.
If I am playing my PS4 or streaming Netflix (or anything that requires a connection), I notice the connection speed rapidly drops to somewhere in the range of 0-5 kb/s as soon as my N9 connects to the network. When I deactivate the N9's wifi, the connection returns to normal speed immediately.
I am still connected to the network when speeds are low, but data crawls. I am able to connect to the router's config page and can see that traffic caps out at about 5kb/s down and 60 kb/s up.
Here are some of the fixes I've attempted, which all failed to produce results:
resetting the router
resetting my modem
disconnecting all other devices
switching channels on the 2.4 and 5GHz bands manually
updating the firmware of the router
changing the network name
changing the network password
changing the network security type
I am typing this after having reset my N9 to factory settings for the second time to confirm that the issue lies within one of the firmware updates. Can someone please help a networking noob figure out how the connection of one device quickly (within 15 seconds) halts all traffic?
I should mention that the exact same issue was present on my N5 earlier this year (long before Lollipop arrived) but that it eventually worked itself out and stopped hijacking my network. Unfortunately without mobile data on my N9, it is essentially useless until I figure out the issue.
Thanks in advance for any help!
The first thing that came to mind is an ip conflict. Have you tried changing to a static ip on your nexus 9?
Edit: Also when your nexus 9 is connected check and make sure the ip address on your other devices jives w/ you router (you may need to make all devices static until you find the problem) I had the same router as you and i had a network switch that was throwing odd ip address to devices not even attached to it...
I updated to 5.0.1 again and didn't have any issues this time around. I went ahead and set a static IP anyways but I'll report back here if I have any issues. Thank you!
I'm having trouble with keeping my Redmi Note 2 connected to home Wi-Fi. In the Wi-Fi menu, it often shows "Authentication problem". I am not experiencing this issue with any other Wi-Fi connection. Also, I have double checked to make sure the password is correct, and it definitely is not a password problem as it sometimes works.
I've even tried changing the password of my router, as well as the SSID (router wireless network name) to something else, thinking that it may have been a factor. Both methods did not help.
In addition to this, I am getting very poor reception at home for my data connection speeds. I don't think this is an issue with the phone though, as an iPhone 6S at home also has poor reception. However, I'm trying to figure out how to reset the network settings and I can't find it anywhere in the menus..
Would appreciate any assistance! Thanks.
More info.
What rom?
Which router, running which band?
Are you using n speeds, dual channels, single channel, wpa, wpa2 etc.
First thing I would try is set the router to G only (WPA_PSK). If that doesn't work, change the channel. Asus routers (the cheaper ones - e.g. NM10) can go coo coo bananas and fail to authenticate random devices, while others work just fine.
Try upgrading to the latest stable global xiaomi.eu rom. Get it here. Also, read the instructions how to flash there.

Sorry. Using SMIUI 7 by sebsch1991 (according to Settings -> About, based on 5.11.5).
I haven't fixed the problem yet.. but I realise that the Wi-Fi issue seems to "reset" itself after I restart. So whenever I notice that the Wi-Fi is no longer connecting, I just restart my Redmi Note 2 and it is able to connect again. Seems to occur in 24-hr loops?
I am using a D-Link DIR-865L. I have two bands (2.4GHz and 5.0GHz). Using the highest level of security I think? In my router settings, it shows I am using WPA/WPA2 (auto mode so it adapts to the device I believe). 802.11 mode is mixed (n, g and b).
The network settings issue I haven't found a fixed for yet, but to be honest haven't looked very far.. and I think it may be a telco issue.

When I first started trying out different ROMs, I found a few of them gave me WiFi issues with different networks. Some networks would behave normally, others wouldn't connect at all. I believe SMIUI was one of the ones that gave me trouble with at least one of the networks I use regularly, so I had to go with a different ROM.
I can't guarantee that you're having the same issue, but swapping ROMs is my best advice.
