It happened to me last night on the Captivate. I tried battery pulls, deleting the WiFi nets, etc., but it still kept turning WiFi off within a minute of turning it on. I did a factory reset (I'm getting better at this process. Can restore my device back to its former glory within an hour).
View 2 Replies View RelatedI got the samsung captivate for AT&T a couple of weeks ago and have run into a few problems with it:
1) Wifi worked great for a while, but now it says unable to scan for networks and turns the wifi off...this wouldn't be too bad if I had a big data plan but I do not.
2) Battery Life...fml
3) I cannot find ANYWHERE any supporting software to sync media files with my PC
4) The drivers will not install on my computer
5) Way too many apps are using data without me even opening them (navigation, yahoo mail etc...) I have AdvAppKiller but that gets old
It is wonderful having such a wonderful, fast device with 16 gb of memory, but these shortcomings are making me realize why I enjoyed a flip phone for so long.
I'm having the dreaded "Unable to Scan for Networks" in the WIFI. Can I fix without doing a reset? I'm on vodafone UK. All the info I have been reading points to me having to do a master reset. Or deleting a file if my phone is rooted. Can I root my phone to do this? or is this not possibly on a voda contact mobile. After I accidentally removed my WiFi from my phone. Then added it again. Getting my WiFi working. Info about Rooted phones (is it possible with mine?). A good backup software for PC, is kies any good what does it backup?

View 7 Replies View RelatedIn Jan. I switched from Sprint to a different carrier and got a new phone with the new carrier which left me with my HTC Evo 4G and I've been trying to use the Wifi so I can use it at work or at home when I don't feel like using my laptop and whenever I try to turn my WiFi on it just turns on then off and tells me "Unable to scan for networks".
I've noticed that it says that my IP address is unknown and Bluetooth isn't working either. I did a factory reset on my phone and all that did was delete my Doctor Who background.
Sidenote: my husband was on my family plan and he had the same phone with the same service and his WiFi is working fine.
After rooting with DooMLoRD v4 tool my china A6380 Android 2.3, which has mt6516 416MHz and Android 2.2.1 instead, wifi stopped working.
Tried unroot and factory reset but no luck, still "Unable to scan for networks".

I'm trying to scan for wireless networks and found this helpful source on the net. Unfortunately it's not working and I have no idea why. My problem is that I can't wait 10 minutes for the result - I need them within a few seconds and thought about setting the boolean variable waiting on false as soon as I get a result, well it runs forever. Looks like nothing is received.

I am programming for google android and I wonder if the scans for wireless 802.11 networks are done passively or actively? I mean: Does the device actually emit a beacon request signal on
WifiManager.startScan()
Or does it just listen for beacons sent periodically by the access points?
I wrote an android application to request a scan for available WiFi signals around, using the WifiManager, then dump the results to a file. The program works fine, but this weird bug occurs. Initially I was requesting a scan every 30 seconds, and everything worked fine. I then tried to request a scan every two seconds, I get this strange bug. Everything will work fine for a few minutes, then the time between two scan requests jumps from 2 seconds to 50 seconds for no reason.
Then, for four more scans, it will scan at 2-second intervals, then skip to a 50-second interval, and it continues to do this consistently. With larger time intervals this bug does not appear. Has anyone experienced this bug before? Is there a way to prevent it? Or does Android automatically cancel scan requests if they are too frequent?
I got myself a Samsung Galaxy S. And decided to sell my Milestone to a guy. So when he is testing out the phone the WiFi doesn't scan his office WiFi. It scan every WiFi around us except the office WiFi. I use my Milestone's WiFi all the time. And all the time it scan and detect all the WiFi. Infact 30 mins before the sale I was using the Milestone's WiFi at school to find a map to his place.
Weird thing is when I use my Galaxy S to scan WiFi, it scanned all the WiFi and his office's WiFi too. So does anyone know why my Milestone is able to scan everyone else WiFi except his office's WiFi? It couldn't be hidden because my Galaxy S was about to scan his WiFi. This is extremely bad luck, because I know my Milestone is in perfect working condition and now he would think I'm scamming him.
I am currently doing my Bachelor Project concerning Android Programming.
Therefore i need a possibility to SCAN/DISCOVER Hot-Spots or WLAN's where i can connect to.
In many topics i have read, that the EMULATOR does NOT support WiFi scan with WiFiManager. I also tried using ConnectivityManager or BroadcastReceiver. But it doesn't ever work.
So my question ist the following - is it CORRECT that the emulator does not support any kind of WLAN Scan/Discovery? I need as many comments on this as possible - because only if its REALLY true, that the emulator does not provide WIFI functioanlity, then i can ask for buying a Dev Phone.
And if so, WHY there is no WiFi support within the emulator...?
I'm having a strange issue with WiFi on my Samsung Moment (post CL14 update). I don't remember having this issue prior to the update but I can't say for sure that it was something that started immediately after receiving the update. Whenever I turn on WiFi, it says "Scanning" for about 5 seconds, then an "Unable to Scan for Networks" window pops up. Sometimes it scans just once, other times it scans 2 or 3 times, but eventually it automatically turns off the wireless. At first, I thought the problem was caused by a WiFi toggle widget, so I tried factory resetting the phone to remove all of my downloaded apps, but I had no luck.

View 6 Replies View RelatedI am currently trying to write a class in Android that will Scan for access points, calculate which access point has the best signal and then connect to that access point. So the application will be able to scan on the move and attach to new access points on the go. I have the scanning and calculation of the best signal working. But when it comes to attaching to the best access point I am having trouble. It appears that enableNetwork(netid, othersTrueFalse) is the only method for attaching to an Access point but this causes problems as from my Scan Results I am not able to get the id of the access point with the strongest signal.
This is my code:
---
public void doWifiScan(){ scanTask = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { sResults = wifiManager.scan(getBaseContext());
if(sResults!=null) Log.d("TIMER", "sResults count" + sResults.size());
ScanResult scan = wifiManager.calculateBestAP(sResults);
wifiManager.addNewAccessPoint(scan); } }); }};
t.schedule(scanTask, 3000, 30000); }
---
public ScanResult calculateBestAP(List<ScanResult> sResults){ ScanResult bestSignal = null;
for (ScanResult result : sResults) { if (bestSignal == null || WifiManager.compareSignalLevel(bestSignal.level, result.level) < 0) bestSignal = result;
} String message = String.format("%s networks found. %s is the strongest. %s is the bsid", sResults.size(), bestSignal.SSID, bestSignal.BSSID);
Log.d("sResult", message); return bestSignal; }
---
public void addNewAccessPoint(ScanResult scanResult){ WifiConfiguration wc = new WifiConfiguration();
wc.SSID = '"' + scanResult.SSID + '"';
//wc.preSharedKey = ""password""; wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int res = mainWifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean b = mainWifi.enableNetwork(res, false);
Log.d("WifiPreference", "enableNetwork returned " + b );
}

When I try to use addNewAccessPoint(ScanResult scanResult) it just adds another AP to the list in the settings application with the same name as the one with the best signal, so I end up with loads of duplicates and not actually attaching to them. Can anyone point me in the direction of a better solution?
I am trying to connect to my home wifi, its WEP security on a linksys router, but every time i try to connect it says unable to connect, also idk if there is supposed to be a wifi icon on the top bar but it does not show one at all, appreciate any feedback

I also have my itouch with me and after it connects with hotel server, a sign-on screen comes up and I enter the server password.
Can't get the Captivate to supply a sign-on screen. Is there some other way to enter the server password that was supplied to me?
Is it possible to create a sort of wifi lan network (i.e., make the captivate work as a local area network router without internet access)? this could potentially be useful: quick filesharing, improvised LAN for games, etc...

View 1 Replies View RelatedIs there a windows 7 software that can scan folder size on my Samsung Galaxy s4.
I'm missing space on my phone, and seemed to the software I have installed on the phone is hard to see it properly.
I've extended my wireless network to cover some weak areas in our house. The original wifi router is in my upstairs office, but gave poor coverage in some downstairs rooms, so I set up an "extended service set" wireless network with two access points, the original router upstairs and a Solwise homeplug WiFi extender extender downstairs (with a powerline link between the wireless router and the Solwise wifi extender), each using a different channel but the same WPA password.Every other wireless device in the house works happily between the two, but my Desire only seems to want to log on to the main router and defaults to mobile internet access in the 'difficult' areas. It seems to repeatedly try to get an address from the network downstairs, but reports 'unsuccessful' and keeps retrying.Any suggestions?
View 1 Replies View RelatedI have a rooted samsung captivate with sideloading enabled. After experimenting with different wifi tethering apps from the unofficial market, I began experiencing difficulties with my wifi connection. Even after uninstalling every app that I thought was changing the wifi state, the problem still persists. I can turn on the wifi and it will act normally for about 30 seconds before turning off without user intervention. In dmesg, the error is as follows: 'mmc1: Got command interrupt 0x00060001 even though no command operation was in progress.' Is this caused by an app or is this a more complicated problem?
View 15 Replies View RelatedI seem to have an intermittent error when trying to start WiFi. Mostly (>95%) of the time I get "unable to start WiFi". Occasionally it works but this is rare and usually when it has been switched off for a few days. The problem occurs when I try to start via the wi-fi widget or via the MenuSettingsWireless controls path. I'm reluctant to do a factory reset unless I really have no other option.

I rooted my captivate thinking that i could install apps that are blocked on my phone, like Sirius XM, WiFI tethering.....even after rooting the programs are still being blocked and i cant install them. am i missing something? im new to android and had an iphone that i jail broke. im confused on what rooting actually.
View 8 Replies View RelatedI turn the 4g on and it immediately shuts off when it says scanning. It only rarely actually works and this has only been happening the past month or so. I just rooted it with unrevoked3 last week though. the problem has been before that. I do now have wireless tether installed but I don't have it active when I try to update. I've tried it with Wireless tether On and Off, with Mobile Connection On and Off, with Sprint Hotspot On and Off, nothing makes a difference. I've rebooted numerous times. The past few days I've been using Advanced Task Killer to kill apps every 30 minutes in aggressive which gives me crazy good battery life even with syncing and fairly bright light and normal usage. Like three days with only two spots of 30 minute charging. It also charges much faster though.
I don't know why it works sometimes. I can't find anything linking the working moments. I'm in a fairly good 4G area when it works, I get around 1.3 megabytes coming down at the peak. Is there anything I can do? Is anyone else experiencing this? I would think that if it actually scanned, it would take longer than an eighth of a second to do so.
