Hi All.
I've got a problem on my International version of Galaxy S.
Sometimes when I restarted my phone, the 3G connection seems won't connect.
I tried to open Maps, market, browser, or any apps that use internet connection. But the 3G seems won't be able to be triggered to turn ON.
Funny thing is, that when I can find a wifi connection and connect to that wifi network, and disconnect the wifi afterward, then the 3G starts to be connected.
It seems that 3G can only be triggered by disconnection of a wifi network.
Can any one help me with this.
Thank you
Can you please clarify why 3G is disconnected in the first place? On my phone I never turn off 3G or WIFI but just let the phone switch on whichever it wants, this method has never given me any problems.

I didn't, I just restarted the phone, and 3G never start as I mentioned before.
I have a Samsung Galaxy S Vibrant device and a strange Wi-Fi connection problem.
It seems that the WiFi conneciton is being lost intermitently with no apparent reason. I ping the device, most of the time there is a 'Request timed out' and only sometimes a 'Reply from <address>'.
On the device side the connection behaves erratically as well, sometimes there is connection but most of the times there isn't. The strange thing is that under device's Settings->Wireless and network->wi-Fi settings the connection's status is "Connected" all of the time, signal strength is excellent, link speed is 54Mbps.
I had this issue on a native 2.1 Samsung Galaxy S Vibrant install, then decided to flash a custom 2.2 ROM hoping to end the mistery. The new custom ROM is an Axura21VE.zip and the WiFi connection problem is exaclty the same as before.
Does anyone have the same WIFi issue as I have? And yes, I did a search before posting this. In fact, I searched for several weeks and saw many SGS Wi-Fi problems being reported but either they are different or they are similar to mine with no solution. Since I need a stable Internet connection on the device for app development, next logical step would be looking at reverse USB tethering. Yet decided to post here before giving up on Wi-Fi.
For the record, the Wi-Fi acces point is under my control, i have a ASUS P5B-MX/WiFi i946GZ motherboard, windows XP sp3. I tried, I think,
every possible combination of Wi-Fi settings available. The only client device I have at home is SGS. At the office network, SGS is having the same
Wi-Fi issues, while a HTC Desire and many laptops don't.
here is what I just found out: if I do a constant ping form the device to google.com for example, then the conenciton is maintained all right. So, should I constantly ping something to maintain a decent connection? Is there a setting or something in Android OS I am missing?
I had this exact problem - changed my router and it works perfect now. Really weird and not an ideal solution but worked for me so far (touch wood!). Try playing about with your wifi config maybe, change encryption, channel etc. Good luck.
Hi, I'm having the same problem on my Galaxy S i9000 on Darkyy's v7.8. I never used to have this problem until I flashed the second to last release. The device says I'm connected to the network but I can't get any internet access. I tried reflashing my official firmware DXJPA, but I still no joy. I'm not really sure what to do.
YES... i have been searching for days. I feel I may have a similar issue. im connected, speed good, IP there.. no data, browser just hangs. seems to happen less in stock. (Rogers captivate, P10.1) also WiFi manager reads my WiFi channel off by 2!! so im set to use ch 9 on the router and WiFi manager on the captivate says its broadcasting on ch 7?? any ideas? ping to infinity??
side note: this happens on all routers and all roms. other galaxys on my network read proper ch... GF's Iphone see the right channel?? HELP..
I'm also having these problems, reposting my reply from another forum:
Just wanted to chime in that I am also having these problems with my samsung vibrant. Seems to only happen from my work router but happens very consistently. Wifi will work immediately after setting it up but after a short time period will stop working completely. It will say it is still on wifi but will in fact have no access to the local network or the internet. Stopping/restarting the wifi connection doesn't fix it. The router has to be manually 'forgotten' and then re-added for it to begin working again. (Update: sometimes this does not work either, in fact).
This is with a 2wire modem (standard issue by at&t) using WEP security in 802.11b/g mode.
Some people recommended switching from 201.11b/g to pure 201.11g. I tried this with no luck. It was also recommended to try to app 'wifi fixer'. This also did nothing to solve the problem. Given that it is my work router, I don't want to go changing the encryption and other crazy things as I'm not the only person using this router and it would break the connection for others.
MRSizzle in another thread (which xda isn't allowing my to link to) seemed to accurately describe the problem as such:
"It appears to be a driver issue with the Samsung base OS drivers in the phone. Possibly sleep policy is not operating correctly and the wifi radio is being disabled by the hardware and is not being controlled correctly by the software so the WiFI icon still appeers to indicate the phone is connected. Also the wifi signal is not being correctly reported. the signal appears to be attenuated more than it really is."
This description would line up with the OP's reports that repeated pinging will keep the connection alive.

Anyone figure this out? I'm trying to use the Web Desktop app but can't because I can't even establish a connection with my phone!
Hi friends,
I have similar problem, but at first I easilly connected to Internet, but now I can connect to my WI-FI but no internet connection. I am not sure but maybe this has occur after updating to Android 2.2.
Any suggestion?
Thanks in advance.
explanation and apology
I was wrong in my assumption that it's an Android device problem. The problem was in the Asus motherboards embedded Wi-Fi access point. I bought a separate Wi-Fi router and now everything works like a charm.
Hey guys, I just received my Note 5 today. But it's weird that my WiFi connectivity has issues. When I typed my passcode for WiFi, it was unable to connect and always flashing WiFi page. After couple seconds, it showed identification error(I'm sure that passcode is correct). It even cannot connect to WiFi without passcode. Any ideas?
I've had the exact same issues when I reset my phone. And I've done that a lot lately while trying to find out the issue with the 10sec unlock lag - which I seemed to have narrowed down to Android Wear and my LG G watch (possible Bluetooth issues)
To bypass the issue you have, I end up setting up the phone using 4G, then reconnecting wifi and it works...
What version N920I do you have? 32gb or 64gb?
Dear all,
I'm experiencing a new issue with Huawei P20 Pro.
When I turn on tethering via hotspot button, phone loses mobile datalink.
This is strange, because app google chrome tells that there is no connection available.
ERR_INTERNET_DISCONNECTED
But from the device connected via tethering, it can connect with no issues.
It seems like the phone can serve just one device at a time.
In fact, if I deactivate hotspot, phone connection works again.
This has never happened before, I tried rebooting the device but nothing changed.
My phone is not rooted
Any idea?
issue solved by resetting network settings on phone
If someone is experiencing the same issue
follow these steps
I can't publish links so please google for " Reset Network Settings HUAWEI P20 Pro"
Hay guys,
I am really at a loss, so I hope you can help me here.
WiFi on my phone works totally fine until I install the EMUI Update 10.0.0.185 (and later).
From that point on, I can't use my WiFi at all. The Phone is still showing me a list of all the available Networks, but If I want to connect to one of these, the phone's WiFi turns off by itself. Just du turn itself on again a few seconds later... and turning off again eventually.
This happens to all of the WiFi networks, I've tried. Also I can't setup a WiFi hotspot anymore or use wireless display feature.
If I reset my phone to the EMUI-Version it came with, everything works flawless.
Any idea, what could cause the problem?
