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).

WIFI settings of hidden WLAN

Hello all,
I have a WIFI network at home that is hidden, which means that he SSID is not broadcast into the world. You have to know it to connect to it, and I also made it very long.
This is not a problem on my laptop, which connects fine, if slow sometimes.
However, on my kaiser, this gives serious problems.
The first day i got it I happily entered all the required settings (SSID, WPA-PSK, network key etc) and pling! I was connected. Yesterday evening however I noticed that all those settings were gone! I entered them again but couldn't connect. And presto, settings were gone again!
Why doesn't it remember the settings I punch in? Is there any way to enforce this?
Thanks,
Philbert

Strange, because mine retains the settings of any hidden WiFi network that I've put in there.

hello
i use WPA/PSK-TKIP encryption on my router.
at wifi settings in kaiser, you have to add your hidden ssid name, and check "this is a hidden network" checkbox.
it works for me fine
(ps.: i use MAC addrass filter on my router, my pda, notebook and PC's MAC's are added to my router, and they only have access to my router' internet.)

This is a bug within MS WM OS, not a problem with your device or anything HTC have done. It should hopefully be resolved in 6.1 (hopefully!)
I've seen it on my own unit at times. If the unit has trouble connecting to the access point and there can be many reasons for this, WM gives a 'burp' and settings are lost.
Try updating your router firmware or use AES encryption instead of TKIP as some earlier versions of TKIP are not fully compatible (Linksys is a prime example).

Thanks
Thanks for replying everyone.
I just switched on my wifi and it immediately found my network, without the need for inputting my settings. I think this problem occurs only when the handshake with the network times out for some reason.
So that makes it only a nuisance that appears sometimes, not a disaster.
Thanks,
Philbert

WiFi connection troubles

Dear friends,
I'm experiencing problems connecting to secured WiFi spots.
The device sees and connects to secured WiFi points correctly, the connection is good and stable. However it seems that nothing works through them - I cannot open any website. Honestly, I didn't try to connect to unsecured networks (I had no chance to find such).
Does anybody have the same problem? Is it solvable? Should I change something in WLAN configuration?
Please help.
Thanks.

Hello,
Try to change your wifi "Power mode" to "Best performance".

Alex

Did you looked up if your HD has a IP, and is listed in the list of dhcp clients (if you are using dhcp). For me it seems that the connection isn't set up correctly, but with the information given above its just a guess.

Same problem here. After two months of great operation and no changes, suddenly this.
This and similar problems are all over the threads.

Ditto, exactly the same probs, cannot acquire an ip address via dhcp from my home router.
Set one up manually and the HD connects to the network but cannot open up any sites, cannot connect to email and cannot download any rss feeds. It seems that any prog that needs to connect to the web cannot.
Same problems trying to connect using the mobile network. Tried a hard reset with no joy. Am going to try flashing a new rom.

[Q] VPN issues

Hi All,
I am having issues when trying to connect to my work VPN. I need VPN access in order to check my work email and browse an internal website.
Now, the VPN always connects, either on 3G (in UK) and wifi.
However, even if it says "connected", I am not able to download emails orbrowse the intranet unless when connected to my home wifi and sometimes on mobile internet.
If connected through other wifi networks (recently tried on a hotel free wifi, in the states and on a private home network, in Croatia), the connection itself seems to go through some sort of bottleneck, and no emails or browsing is then available.
I am blaming the phone itself, since my colleague had no problems whatsoever on his iPhone.
I am on Galaxy Note, non rooted, Vodafone UK.
Please help, this issue is making my Galaxy Note almost useless.

just FYI I'm also on UK Vodafone and I can connect fine with openVPN to my home network ... tested on 2G,3G/H+ and also on various public & private WiFi networks - always connects fine, only issue I have is that my server .ovpn tells the phone to use my home router as it's default gateway (so that I can browse securely on public wifi). This doesn't work out of the box - I need to use the openVPN app's "fix DNS" option.

errr ... I'm an android noob, but AFAIK you need root for openVPN to work? I never tried running openVPN on my note BEFORE I rooted it, but anything I've ever read says root is required?

What APN do you use?
I have to switch everytime to something called MyLan to connect over 3G.
I am using the stock VPN client, did not adventure myself into OpenVPN. Would that work with an encrypted VPN?

Ah, sorry - I somehow managed to read the thread title "[Q] VPN issues" as "OpenVPN issues" .. case of my eyes seeing what they wanted to rather than than what was actually there. You are of course right, the stock VPN options don't need root (and of course openVPN client will only work to talk to an openVPN server).
I did set up a PPTP server on my WinXP home machine and tested that with the note's inbuilt PPTP VPN client - it worked OK although I needed to turn off encryption, and I didn't do anything with it beyond just connecting as I was only dong it out of interest.
re. the APN - I don't actually know where to see that on the note (noob, as I said!) - when I do settings->wireless & network-> mobile networks, which claims to allow setting APN's, there is no info or settings re. the APN other than the "network mode" and "network operators" items, neither of which seem to show the APN used for vodafone data access.
Anyway, sorry for the bum steer, hope you get it sorted

Oh, never mind
Under mobile networks you have to go under Access Point Names, but most likely you will only have one APN, which is the regular from Vodafone.
So most likely is the encryption causing problems?

D'oh ... I thought that was a heading, didn't realise it was a clickable item! my APN is wap.vodafone.co.uk (APN type is "internet+mms").
IDK if encryption is anything to do with your issues ... I doubt it if you can consistantly connect from home wifi and sometimes from 3G - if encryption were the problem I'd imagine it would consistantly connect (or not) rather than be variable.
Maybe worth trying to ping your internal mail/intranet servers when connected and then talking to your work IT guys in case there are firewall/routing settings that you are somehow falling foul of?

Yes we are doing that, however that fact that iPhones can connect really makes me wonder!

Thread Moved To Q&A​
This is a question, and as such belongs in the Q&A Section​

there are lots of third party vpn tools and free available you can use those

Wilsonj,
Can you please suggest one third party vpn tools that works well on PPTP, with encryption?
I am not looking at OpenVPN, since it doesn't suit my needs.
Thanks!

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
Sefari

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.)
