Samsung Galaxy S II :: "No Connection" On Wifi?
Jul 31, 2012
Often when I try to connect through an app (google play, fb etc) the phone won't seem to recognise any connection. It just tries to load for ages and then says "No connection" and shows me a retry button which doesn't work either.This happens even when I'm sitting right next to my router and the status bar indicator shows full wi fi reception. Sometimes swtiching wifi off and on again a few times seems to sort it out, but mostly not. Other times it works fine and I'm not doing anything noticeably different.I know I'm clutching at straws here but Any idea what the problem could be or how I could diagnose the cause?

My new Galaxy s2 is having trouble connecting to my routers Wifi, a netgear DG834GUv5. I can get it to connect fine if I disable the routers security entirely, but I would not want to keep that up at all. I would like to be able to connect at home. I've been looking up things on the internet for days now, and am getting desperate.

My Samsung GS2 runnig on 2.3.4 has developed a problem. It keeps loosing Wifi connection at home. It connects then disconnects. It is becoming frustrating and annoying. I have uninstalled all apps and still no solution. I know others on here have had similar problems has a solution been found. I have switched the Wifi sleep to never. I have installed wifi fix which resolves it temporarily but then the connection falls off.

Just upgraded my S2 to XWKI4 via Kies.Since then I can't see a way of safely disconnecting the USB connection on the phone when it's connected to the PC.reviously I have pressed the home button to disconnect but I can only see a USB symbol at the top of the phone display now. Do I just pull the cable now?

My S2 is on 3 UK.
For some reason i cannot connect to the mobile internet when the connection is showing 3g. It will only connect when it is showing H or H+.
Also for some strange reason, the internet connection wont work at all if i havent used it for a few hours. To get back internet you have to go to flight mode and back or switch off and on to get back online.

Having problem with Lollipop and the WiFi connection getting dropped. Last night I was browsing the web on my S4 and noticed that the WiFi connection kept dropping in an out! Rebooted and did a cache wipe! Seems to be ok now but will wait and see. Still not convinced I shouldn't just flash this thing back to 4.4.2

Yesterday i used the the mobile data connection just as normal. I downloaded from the store and everything. Then i was back in wlan. I tried Fring. I wanted to try Fring also on 3G or Edge or HDSPA or whatever comes out from my handy and goes into the air ^^ I don't know anymore.So I turned off my wlan and was down. No internet anymore and even there was no icon in the toolbar.
I turned my phone on and off, unistalled every app i installed since the last time it worked, which was just an hour before that.
The things i installed were: A brightness widget (appears under volume controll if you press the volume buttons. I forgot the name.) and "Quicksettings", which leeded to uninstalling the first mentioned unit.After that didn't help either, i changed the card in my phone with another from the same provider. It didn't work. In the same move i put my card to another smartphone and got a connection.Conclusion: Either my phone is misconfigured (which i hope for) or it's broken (which would suck but i have warrenty left).
I even tried to let my provider send me the right connection data and saved them. Nothing...I know there is the way of getting back to factory settings, but i only want to try that if i'm running out of possibilities. And of course i don't want to lose my app data. my phone is not rooted now and i know i have to, to save my app data and apps (which sucks. 1-0 for the iPhone). I you have only ideas that could be done by rooting my phone i would do so, but i would rather avoid that because of the 'maybe warranty loose'.

I've just got a new SGS2. I've paired it with a VW Passat from 2011. Everything is working fine except transferring the contact list, only around half of the contacts get transferred -- 125 of 205. I can't find out why some contacts get transferred and others don't. Before I had a Palm Pre 2 and it worked just fine... all contacts would transfer perfectly.
I've unpair the connection several times in the Bluetooth settings, delete the connection in the car and pair again but didn't solve the problem. I've also update some of the key contacts that don't get synced, forced a reload of the contact list in the car menu but nothing works.

In my SGS2, I navigate Settings-> Myphone-> Software Update
If I click this, I get a popup window says "Connecting to Server" but after few seconds it says "Connection failed".
I am in India, using 3G Vodafone connection. I have checked and ensured that my internet connection is working fine.
All I wanted to know, what purpose this option is given here..as everywhere its mentioned software update can be done via Keis/Odin?
Why always I am getting a "Connection failed" message? What server its trying to connect to?

Since upgrading to ICS, connecting to my car stereo via bluetooth causes the phone to reboot itself. At first i thought it was just whilst streaming music was causing it as i could play 3 or 4 tracks before the phone just shuts down and reboots.
However, today i just had it connected for the phone function only and the same thing happened after 5 - 6 minutes.
The stereo is a Sony MEX-BT3900U which worked perfectly prior to the upgrade.
Carried out the upgrade using Odin3 v1.85 and flashed following one of the guides on the forum. Everthing else appears to be working fine and i quite like the new look etc, but if i can't find a solution to the phone rebooting itself think i will go back to GB.

The problem with the SGS II is that there's no connect to PC setting. The other problem is that to connect to as a mass storage device, you have to manually do this every time - In my car, the phone repeatedly beeps at me until I enter the USB connect screen, which is very annoying.

I have successfully 'paired' my new S2 to my Ford Focus audio system, and it makes and receives phone calls fine - hands free. However - the current settings do not transfer my 'contacts' list to the car system. Every time I turn on the car ignition I get a little 'tune' from the phone, and a notification that says (something like) 'Ford audio would like to share your address book' and an option to 'OK' or cancel. If I click 'OK' my contacts are listed on the car system. There is also another window which says 'Do not ask again'Has anyone else had this issue - because I am getting fed up with having to allow the phone and car to share my contacts list every time I turn on the ignition.

Whenever I try to run the android update it says "Searching for server" then report, "Server connection failure". This goes running though either wireless or 3g connection. The SII works fine downloading/uploading everything/everywhere else and on any connection, it has me baffled. It has worked before as it did a couple of updates when I first bought this really great phone!

My previous phone was HTC Wildfire S (stock Android 2.3.3) and I was able to receive and send MMS with data connection turned off. Simply, when I send MMS phone automatically turn on data connection. Same, when somebody send MMS to me, Wildfire S automatically turn on data connection and retrieve MMS. Now I am using Samsung Galaxy S2. I have to keep data connection always on if I want to send and receive MMS. I don't want data connection to be always on because I haven't flat data plan. I tried Quick Setting app. It change APN for internet and keeps data connection always on (do not modify MMS settings). At this way I can use MMS normally, but my battery drain for just 8 hours!

Ever since the last firmware update my Galaxy S2 keeps deciding to tell me that I am connected to my wifi network at home. It's extremely annoying because I could be in the middle of a game and this message appears. How I can stop it from being displayed??

So this just started happening about a week ago and its really annoying! My instagram and snapchat will not refresh or load at all unless I turn off my wifi and use my data. I've tried restarting my phone and resetting it by taking out the battery and stuff but nothing works.
So to make it clear the apps work while using Data but does not work when Im using my WiFi. And just last week I could use my WiFi for the apps and now i cant. I haven't updated my phone at all since then either.

I just today bought the new Samsung Galaxy S2 HD LTE.
I got one problem already, which I didn't really expect. It finds more less all wifi's, at least the once I know of. I still use my iPhone 4, so the iPhone connects without any problems, but my S2 LTE can't even find it.

I know this has probably been asked and answered a thousand times but...I recently took over ownership of a Galaxy 2 from someone else in the family and only use internet through wifi as I dont have data included in my tariff.However, I just saw on latest bill, I have a load of charges for data usage!I have done various searches and there seems to be lots of solutions but no DEFINITIVE one that i have read?The most obvious one I have read is to switch the data mode off from the power button. Another is to deactivate packet data in the network menu (I would have thought the first action would do the same?). I have done both but the charges still continue. I assume then that some apps are running in the background and accessing at random times?
So is what I am describing a normal 'feature' of the phone? Why is the phone allowing apps to override a very high level user setting???If this is the case, my searching has now left me baffled. I have read about downloading apps to switch the 3G connection off? Also I read I could set the phone to run on 2G?Does setting the phone on 2G affect any other functionality? I would like to use the phone for everything else eg wifi gps etc. I just dont want any non wifi internet data usage at all permanently!Lastly, I believe with the network internet connection, I cannot send or receive mms at all? I guess I will have to accept that.

I've had my Galaxy S II for 5 months now and have always gotten it connected to my home's wifi. Now for some reason it's not connecting. My wifi is up and running fine (connected on my PC as I type this), the password is set fine for the Galaxy, but instead of connecting, Settings only says "Saved, secured with WPA/WPA2" after clicking "Connect". Signal strength is noted as "Excellent". I've tried re-entering the password several times, but the same results every time.

I've just bought my first Samsung Galaxy S2 and love it to bits. The only problem I've encountered in the three days I've had it is that it won't connect via wifi to my home computer (a Mac). With my Mac's 'Airport' and 'Internet Sharing' turned on, my boyfriend can connect to wifi from the Mac to his iPhone but my S2 refuses to connect. Once I turn on wifi on the S2, under 'Wi-Fi networks' it brings up my computer and my neighbours' wifi networks. I click on my computer's name, type in the password, but then it just cycles from 'Scanning...', 'Connecting..' to 'Disconnected'. I've spent hours trawling Google for a solution. Under the 'Advanced' wifi settings I selected 'Use static IP' (but I'm not convinced I put in the right numbers under 'IP address', 'Gateway', 'Netmask' and 'DNS'). I don't know if it makes a difference but in System Preferences > Network > Airport, it says 'Airport has a self-assigned IP address and may not be able to connect to the Internet'. But my computer is clearly visible on the wifi network because my boyfriend could connect wifi from my computer to his iPhone.

i have a problem with my Samsung galaxy S2 nowadays with following detail: i can't use any application via wifi but can use all by packet data. FYI, my connection to wifi is fully correct and is in coverage area and normally signal strength is excellent, it mean i don't have any problem to connect to wifi in all places same as home, office or any other places. but i'm wonder that why i can't use any, yes any application even simple factory pre-installed applications same as google search when wifi is active but if i turn off my wifi and using packet data, all, yes all of applications working properly. FYI, my all applications worked properly before this problem raised (i'm not sure but seems my problme appeared when i backed from china trip which i changed my SIM card in china with a Chinese SIM card) so, i believe there is some mistake in setting which maybe occurred

How can I disable wifi and keep it switched off until I want to use it again, while keeping other radio services on.
I have pretty bad wi fi reception in my bedroom, however it's just sufficient for my phone to detect it and connect, but it drops out and syncing/downloading/loading web pages is very slow ad often fails.
