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...?

Wasted thread
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 issues with a repeater

I just got my self an Asus N12 router/repeater and already set it up for repeater mode, verified with a laptop places on the house that formerly had very low signal now shows almost a full bar now the problem I have is that the Galaxy Note seems to only want to connect to the main router which gives it like a very low or even dropped signal, using an app called wifi analizer it can show both my main router and the repeater ( both have the same SSID and only shows a different mac address of some sort, the repeater is actually detected giving off good signal but then again it always connects to the main router.. I never had to setup anything on the laptop it just gets better over all signal.
EDIT:
This is what Wifi Analizer sees
Home (00:23:59:11:11:71)
Home (bc:ae:c5:b0:3a:78)
first one is my primary router and the 2nd one is my asus, the note always prefers to connect to the primary router and ignores the signal from the repeater.. the laptops on the other hand get the signal boost!

Good thread to second the question.
Is it possible to set the Roaming Aggressiveness for the Note?
In simpler words - if i have two signals (say, identical as the OPs config) i want to switch between them before the connections to the connected one has been dropped. In other words - is there a way to switch WiFi networks beneath signal strength value or on better signal from known network?

Im also looking for something like that, I've read before that tasker can do that kind of switching.

I had the exact same problem and this fixed it. It uses just 472Kb and it works. Thanks!
To use it, open it, Menu, Preference, Access Point(AP) and choose your preferred network.
It would be nice if I could set up multiple preferred access points, but I can live with the inconvenience of choosing a network while I'm travelling. I was getting annoyed with having to keep doing it at home though.
Hope it will resolve your problem.

You could try this with the free Wi-Fi Rules (a WIFI Manager) app in the market.
It allows you to set connect priorities...
Or even Wif-Fi scanner wRecX(Free) where your device can connect with the retrieved access points specified in the list...

That is annoying! I just bought a repeater. I guess I'll be having the same problems ...

I will try both solutions once I have my repeater up and running again, It is currently used as my primary router as it gives a better over all coverage compared to my old router but I will go back to using the repeater when I have the time to do so.

tried a different ssid on the repeater?

A repeater automatically configured to have the same SSID at least on the Asus repeater mode, Access Point mode on the other hand allows you to use a different SSID but you need a LAN cable to connect to it.
After setting it back up, I've already figured it out that if I needed to connect to my repeater I must have a static IP settings on my phone.. for some odd reason it does not provide any IP from the DHCP of the primary router, so when I go up a floor I just need to reconnect manually to the primary router by turning the wifi toggle off then on again.

I have exactly the same issue, Static IP works but Notes can't pick an IP while connected to the repeater only work workarounds I found 1. static ip, 2. setup DHCP on the repeater too.
and I hate both
did you made any progress on this ?

Static IP is the only work around I found for this to work, my laptop though connects to the repeater with out issues and the need for static IP. Same issue with the Galaxy tab7.7 Im guessing this could be an andriod/samsung issue.

There is a known issue with some Samsung Android phones, including Note, failing to support BSSID roaming. That is were the wifi device hands over between separate APs with the same SSID.
More info here: http://code.google.com/p/android/issues/detail?id=12649
You could set your repeater to use a different SSID, if supported. I have had success with BSSID roaming when using Imilka's CM9 build for the Note.
Hope that helps.

Thanks to both, yes all other devices works just fine here too. Just my note and wife's S2 having problems
Good to know it is a bug and sad to notice still the same in ICS

I cant see the option for my Repeater to be labelled differently

by definition a repeater will have the ssid that the main one

Yes, but some Asus models do have the ability to have it renamed.

Can wifi and 3G run at same time?

Can wifi and 3G run at same time? I need them together, wifi to print via wireless printer and 3G to use net.

Technically, not a problem to have both active. Problem might be that the app you want to use for wifi could map itself to the internet/3g connection group. Or the program you download with ends up switching to wifi, if that's what the phone prefers when it has two specific connections.
Usually is dependent on the program implementations now, though. But if it seems to work and then somehow fails, the app's connection preferences probably is the problem.

Thanks for the reply but I didn't get you mostly.
I am using HP ePrint app. I want wifi to connect to printer and 3G to recode data to print. Turning on wifi automatically connects to wifi. 3G turns off. Any how to force them stay together?

establishing VPN connection not possible from wifi

Hi,
at first sorry for my english, it's not my main language. At second, I searched but didn't find anything here about my issue.
I set up 2 vpn connections in my P20 Pro (one to work, one to my home). Both vpn connections are working if I am connecting from mobile network connection. But the connection won't establish when trying to connect from a Wi-Fi (doesn't matter which, tried several different Wi-Fi's). The ports are open, the credentials etc. are correct and it's working from Wi-Fi on another Smartphone without problems.
I go to the vpn-menu, hit connect and 1 second later I get the message "not successful" for both connections.
Does anyone have an idea what could be the problem? Is it a known problem?
Thank you in advance
Best

what were the vpn that u hv tried?

I had the same issue. VPN connection was correctly set up to an AVM Fritzbox 7490.
Always used to work with my previous phone, stopped working when I started using my new P20.
When I read your comment a few minutes ago, the VPN connection (no settings changed) all of a sudden worked when I checked.
You may want to retry and check if it works. I don't know if some firmware update fixed the problem in the meantime, but now it works on my device.
Oliver.

I'm using Tunnelbear VPN on my Pro, and so far no problems with using it on wifi. Maybe just restart your Pro.

I have to correct myself here.
Unfortunately it looks like after a fresh reboot the VPN connection over WIFI works. Then after a couple of hours, it fails. Whereas the VPN connection over mobile data works a few seconds after the failed WIFI attempt.
Rebooted - VPN connection over WIFI successful again.
Pretty annoying.
Oliver.

Hi,
sorry, I forgot to post here. For me it worked after turning off "WiFi-Calling" and restarting the phone. I also would like to have WiFi-Calling because of bad cell reception at work but VPN is more important for me.
To be clear, this issue only persists when using integrated android VPN functionality. I didn't try other VPN-Apps from the play-store or somewhere else because I don't use 3rd party VPN-connections.
I didn't try to enable Wifi-Calling and testing VPN after the last upgrade (last week or so). Maybe they fixed it?

Interesting; I didn't know Android now has built-in VPN; going to check it out. (Awhile ago, I decided to go with either Tunnelbear or OpenVPN because they seemed to be the only VPNs that had independent security audits done.)

Note 8 not connecting to Xfinity Wifi

I have a Note 8 running on VZW and my device won't connect to my XFINITY wifi network at home. I tried changing the password encryption to one of the solutions below and I even changed it to open, and it did not work. I also tried changing the IP settings from DHCP to static and that didn't work either. I connect to other wifi hotspots and wifi but not my home. Also, however, I have other devices connected to the wifi just fine. I cannot seem to find a solution to this issue.

Maybe try setting your wifi to a different channel on your router?

is it your home network or xfinity hotspot network
I am a actual xfinity mobile and home internet user
For the life of me I can connect to my home networks but not my home xfinity hotspot also broadcasted from my router. It shows up,I can click it,But never connects....
I also have issues with other xfin hotspots.
Not all but some

It is my home network that my note 8 won't connect to, but it connects to other networks, I believe something is blocking it.

Now I know they got that xfi crap have you gone on your router and xfi app and allowed

Yup I went through all that and the admin tool and nothing. I turned the firewall temporarily too to see if the problem persists and it does.
