The massive wifi problem that many experience

When I turn on my phone at work, the wireless connection (open unsecured) connects and works for a few minutes. After some time, it disconnects and without rebooting my phone, I cannot establish a wlan connection.
This is oly the case at work. At home it works flawlessly, but it is another network kind.
Anyone found a solution to this problem? I saw a lot of threads about this but no good answers.
I am using duttys v3.

Not sure. Perhaps there is some sort of time out on your work network for inactive devices, or dhcp ip releases or something weird and "networky" like that?
Or perhaps your phone is going into a power save mode if you are not using it?
Just general ideas, I don't have this particular problem

I dont think many people have this issue! you must not have a setting correct, try downloading KaiserTweak and adjusting the timeout and also take a look at the routers settings I find it strange that a business would have an open network for security issues

I work at the university, and the network is unsecure. You have to enter login and pass at a webpage to gain access.
I cannot reconnect at all once ive been disconnected. So it should have anything to do with kaisertweak or timeouts.
I have tried every setting and combination. I have tried to select work/internet settings. Ive tried to tell the phone its a hidden network / not hidden network. I have tried to use power save / performance mode. Ive tried to turn off 3g, bluetooth, phone (everything basically).
When I tap connect, it says connecting and then it immediately goes to "active" and tries to connect to another network (which I dont have access to).

I have worked out the problem.. first if its a WPA enterprise connection, make sure its set to WORK and not INTERNET setting. it will work. my only works with schaps versions not duttys

on my old pda (Acer N50 premium) I had the same problem with my unis network... it would only work (if at all) for a few minutes then nada... but at home it was absolutely fine, quick stayed on and totally responsive... I wonder if it has something to do with the rubbish way unis run their IT...?

Many do not have this issue.
According to what's being said here by the indiviuals with issues, you're having problems connecting to a certain network...not all networks.
If it were all networks; your device, settings, equipment or rom would be the common denomenator. Since it's one network, it's that network.
Just because a network is or appears to be available, that doesn't mean that you can connect to it.

no, it could be the phone software. Lets says that a string is added to the registry if the network you are connected to disconnects you; a string that makes the phone cancel connections to the network. And lets assume that the network disconnected you because there is a hidden firewall in the phone software that blocks ping requests, thus making the network believe that the connection is lost and thus disconnecting you. Then we have a moment 22, which is basically something wrong with the phone.
As some readers already pointed out in this "wasted thread", when changing the rom (in one case) or when changing settings from "internet" to "work" (in the second case) there is a great possibility that this problem in fact has to do with phone software and not network.
In my case, it just happens to be neither of the mentioned solutions or any solution that I have found in other threads.

One thing you may want to check is that your wifi is set to max performance. The issue may also be that there is a DNS cache issue, in most cases it can be resolved by manually reconfiguring the connection.
I have been successful in configuring my phone's WLAN to connect to everything from open APS's, WEP, WPA, RADIUS and AP's with proxy redirects, so I can tell you that as with most cases, it's human error.

I have tried max performance.
How do I resolve a dns cache issue? Manually reconfiguring the network did not help (only thing that helps is a reboot).

Connection lost while using WLAN

When i use WLAN the 3G/GSM connection is lost after a few minutes and i have to reboot the phone to get it back. Does anybody know why this might be? Could it be the Radio?

I think its turning it off because your connecting to the internet through the wifi, when you disable wifi it should re-enable the 3g connection, but if it doesnt you can turn on the data connection...
thats what it sounds like is going on from your post. When I turn on wifi it will drop the data connection but has always reconnected to it once I disable wifi or I go outside of my wifi's range and something try's to connect to the net...

Yes, it is logical, you could not have opened two types of connection concurrently. One type closed another one.

ive had the same problem, when i connect to wi-fi i lose the data connection and it doesnt let me browse until i turn wi-fi off...i dont understand the point of wi-fi if u cant browse with the speed since the data connection is lost?

Thanks men! By turning on the data connection after i used wifi it reconnected!

What Wifi allows you to do us connect wirelessly to another connection, at home its my DSL, which is much faster than the edge network, and if I did not have an unlimited data plan wouldnt add to my phone bill. In that way its very usefull. Seeing how its faster and available at home or in places where your cell signal might not be strong or available you can use it to get online.
But you need to tell it your no longer using wifi for it to reconnect through the network to deliver data to you again.

ok so when it comes to wi-fi im a big newbie, i have a tmo wing and have flashed (upgraded) rom...i also have dsl at home how is it i can connect and access this...when i search for wi-fi it usually only picks up my neighbors connections never my own...?

If you have a wifi router or your modem has a build in wifi option you go into your modem to set it up. Most modems / routers come with it broadcasting the SSID so you should see something (usually the default is the name of the manufacturer)
If you have your paperwork you can open your web browser and type in the address to open the internal OS and make changes as you see fit. For example mine is a linksys and its default address was http://192.168.1.1, most routers used to default to that but since a lot of modems are coming out with build in os and firewalls they have that IP so routers can be changed like mine. Once in the OS you can set up your pw so no one else can play with your settings
Navigate to the Wireless section and there should be a bunch of settings. I renamed my WiFi name to match my home network, and disabled the SSID broadcast. Then changed the chanel for some of my other devices, if you dont have anything that requires this leave it alone. Then enable WEP or other protection, 128 bit wep is pretty decent and anyone hacking through it will probably be disappointed with your lack of juicy goods.
Once you have the SSID and the Key encription you go to your phone and mirror the information into the WiFi settings. The web will be a 26 or so string of letters / numbers that will equal the password you set. These must be typed in perfectly or it will not work, took me 6 or so tries to get it typed in correctly but once its in you wont need to do it again unless you reset the phone or change the network settings.
If all that goes through open IE on the phone and hit up google or something, if it loads your online.
Thats a jumbled and messy tutorial, I can fix it to be more user friendly if you need me to do it, but with you not seeing any SSID but your neighbors your wifi is either non existant or disabled...

thanks for the quick reply, ill give it a try...might need the more user friendly version lol sorry

Its no problem, the biggest thing will be weather or not you have a wifi router or modem. Then depending on the brand the IP you have to type in to log into the modem. Each router / modem will have paperwork with it that tells you how to do it, some are different but thankfully most are the same.
The un is usually blank and the pw is usually admin, sometimes now they dont even put one unless you specify it. Once your in the OS its pretty self explanitory, there are lots of things to not mess with, but in the wifi area you can look over my post and figure most of it out,
if you get hung up on somethin just post what it is and ill see what I can do

N1 - 5GHz Wifi?

Does the N1 have 5GHz wifi like the Samsung?
My home LAN is 5GHz only, so I don't disturb the neighbors with my video streaming.

No, 2.4 only...

Ugh.
OK so I turned on the router's 2.4GHz, but with broadcast SSID off. My N1 wouldn't even try to connect. So I turned on router SSID and it connects AES.
I do -not- want SSID broadcast on, as Windows machines' lazy active scan will find me. Sure they'll never get in, but I do not want broadcast on.
Has anyone succeeded in connecting with it off?
When I am connected wifi and open a website on the phone, does it go over wifi preferred over 3G?
I want to share the SD card with a machine on the LAN. What's the best way to do this? FTP? Reverse SSH tunnel? Is there a sshfs for Android? EDIT: NM on this one.

Yes, I remember connecting to a WiFi with SSID off, when I had Nexus.

It is pointless to keep SSID Broadcasting off. It is super easy to find your SSID anyway, and it causes all sorts of additional problems (like the one you are seeing above). Just keep the network secure and it makes life a lot easier.

http://blogs.technet.com/b/steriley/archive/2007/10/16/myth-vs-reality-wireless-ssids.aspx

Ok, but sure passive scanners like Kismet will still see me, however 90% of scans are done with an active scanner like Winduhs. Of course I'm using WPA2-AES, but I want to take every measure possible.
Now I find that whenever I have the phone connected to wifi, I lose -all- internet access. Just times out. 3G is still on and wifi is showing connected, but I can't get to websites. As soon as I turn off Wifi I can access the internet again through 3G.
With wifi I -can- access the wireless router's setup webpage from my phone, which tells me I am working through wifi, and I can remotely mount the phone filesystem on a LAN machine using sshfs, but I can not reach anything outside. Any idea why?
Does anyone know whether, when it's working right, it uses the wifi connection in preference over 3G?

The WiFi is ALWAYS preferred to 3G, which means - when you're connected to WiFi, all the internet traffic is routed through WiFi.

I don't understand then, why all data traffic stops to the outside when wifi is connected. The rest of my LAN gets outside fine, just not the phone.

If you can see LAN computers and exchange data with them - it's not the phone that's making problems. See if you have any restrictions in your router.

Oh FFS, my fault...
I set my IP statically for my LAN, and through some alert troubleshooting I found I can ping IPs outside but not DNs. I'd mis-set the DNS server in wifi settings. Now it works great!
I can now use sshdroid to mount my phone's filesystem on my LAN securely. Now, if I could only get it to wifi associate with beacon off...
It would also be nice to mount a filesystem on my LAN to the phone, although I consider the phone unsecure and question the wisdom of that, even with DroidWall running.

There is a market app that lets you connect to a hidden ssid

Cool, but Market is FCing on me. I did a complete reinstall of the newest MIUI.us, and now Market's FCing again. So can't install any Market apps.

As someone else said, turning SSID off is pointless. It's like taking the numbers off the outside of your house and thinking people driving by won't see your house sitting there.

Apparently you didn't understand what I said here:

If nothing else, please just respect my decision in this regard, or give valid proof that active scanners are not the preponderance.

[Q] Switching between routers within the same wifi

Hey guys, I got a problem with wifi on my One. The thing is I got a couple of wifi routers in my house (one can't cover the entire building) and they're both broadcasting the same SSID, password etc. basically one is connected via RJ45 to the other and set up exactly the same way. Problem is when I move around the house and lose connection to one of my routers and the phone automatically connects to the other all my connections on the phone stop working and I have to turn my wifi off and on again. Same thing happens when I'm at my university, each floor has 2 wifi routers on it and phone tends to jump between them screwing up the internet connection each time. I know it might not be the biggest issue in the world but still it's quite annoying especially since my old SGS didn't have this problem. My phone is not branded and of course up to date. Thanks for any advice.

From my experience after installing a lot of different wifi's in different operation modes, it all depends on how exactly the routers have been setup.
But to answer your initial question- the topic at hand; as long as the wifi's broadcasts the same SSID, you cannot choose which of the two individual routers you want to connect to. Please someone correct me if I'm wrong, but afaik this is not possible. If you want the possibility to choose, then set them up with different SSID's. This would be the _easiest_ solution, just make sure they broadcasts at different frequencies with at least 5 channels apart, i.e. channel 1 and 6, or 6 and 11, or 1 and 11. These are the most popular ones in the 2.4 GHz spectrum. If you use 5 GHz you have a lot more to choose from.
Now, if it's important that your network works seamlessly (with the same SSID), I can provide a step by step guide upon request.
But the solution to your current problem, from my experience; yes you have to turn the wifi off and then on again to "force" the wlan-card on your cell phone to -faster- connect to the closest router, otherwise it will take maybe 15-45 seconds before it does this automatically. It's basically the same with computers. This mostly happens if the wlan-card are within range of both networks, but it will try to stay connected to current one before changing.
And there are some important guidelines to follow when you connect one router to another if they are from the same brand (because of the ip-range and gateway). I once had to setup 8 wifi-routers in a house, because of the size and the thick concrete walls (same SSID)...

The problem is my laptops and other phones don't seem to have this problem, also the phone doesn't 'fix' itself after 40 or so secs it just stays broken as far as I've noticed forever (or at least till i leave my house). Also it doesn't have a problem connecting to the other router, it loses connection, looks for available networks, finds my other router, connects and... nothing works. Exact same thing at the university, finds routers, connects with 5/5 bars and it just doesn't work.

Are you sure you have it setup with DHCP and not some static ip-settings? Can you post some screenshots of your wifi-settings?
If you haven't tried already, get your phone to "forget" it's settings so you have to reenter the password and make sure it's set to DHCP. But first take out the power from both your routers so they get a reboot, and make sure the ethernetcable is connected from one of the LAN ports on the main router connected to the internet (from your cable/dsl/fiber-modem), and in to the WAN/Internet port on the secondary router. Btw what routers do you use as master and slave?

Yes of course I have the routers set up just like you say And yes I'm using DHCP on both of them. They are Airlive 1600GL with tomato rom as main and WR740N as secondary. I took screenshots of what seemed relevant sorry the main router's settings are not in English but it seems that would require me to reflash it with a different rom.

What's with the DNS being 8.8.8.8 and 8.8.4.4?

These are Google DNS.

I would do it simple and solve it by changing the SSID on the slave router to something different, like wireless2, and change channel to 1. Or change the channel on the master router from 8 to 11. Your phone will probably change from one network to another faster this way, or it's at least easier for you to manually choose.
If that doesn't help, and the network is 100% problemfree for other wireless devices, I guess it must be a firmware or hardware problem with your One's wlan-card. Most likely firmware.

I will try it in the morning but still I'm pretty confident it's not the matter of setting up my home network but rather One's software bug. I can't say with 100% certainty right now but I don't remember having this issue before the update to the newest Android version.

Both routers need to be on the same subnet, enable dhcp server on one and disable it on the second one. Also set the second one as an access point only with a static ip in the same subnet.
The problem you have now is that wireless clients must negotiate a new ip when switching routers because of different subnets assigned to each.
Let me know if you need more details.

But still that would fix the problem at my home, what about when I'm somewhere else?

What ROM are you running? I leave wifi enabled all the time and haven't had any issues moving between networks, it automatically connects when another network is in range.

Android 4.3 with Sense 5.5 all stock not even rooted.

Since your completely stock it should just work. I'd try fixing the home network first and see if that solves the issue at home, then move on to trying to figure out the network issue at school.
Router1 - master
Internet connected to wan port
Cable from lan port to a lan port on router2
Dhcp: enabled with an ip range of 192.168.1.100 and up
Lan ip 192.168.1.1
Channel 1
Router2 - slave
Nothing connected to wan port
Cable from Router1 lan port to lan port on this router
Dhcp: disabled
Lan ip 192.168.1.2
Channel 11
Set ssid and wpa settings the same on both routers.
With this setup clients can hop from one access point to the other without a dhcp request or ip change, should switch within seconds.

Tried that setup for many times over the years I've worked with routers, from my experience that is unstable.

[Q] Wireless Roaming for Best Signal?

I have two APs in my house, and my ATT S5 will not actively switch between APs even when connection is dropping. I have both wireless profiles saved to phone. Does anyone know a fix for this? Ideally I'd like it to be fairly aggressive and switch to the strongest AP when available.

You can make one a repeater depending on what type you have. You setup the repeater with the same name and security. Then it will switch seamlessly.

I have it hard wired in for better connectivity, as a result it wont function as a repeater and must have a different SID. If I choose repeater, I am forced to leverage AP1s wireless strength which is weak where the AP is placed. I've seen other threads regarding older Samsung devices and this issue, I was hoping there was a for the phone.

You don't need to use the wireless for this. Set-up the writing from modem to router 1, then router 1 wired to router 2. Turn off dhcp on router 2, and it becomes just an access point. Give them both the same name and wireless password. This is the exact set-up I have.
