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).

I 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 9 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".
logcat follows:

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'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 turn it on, it says its on for like 10 seconds and at the bottom of the screen it says "unable to save networks" and then it says "unable to scan networks" and then it turns right back off

View 7 Replies View RelatedThe wireless network in my area follows the EALP/PEAP protocol which isn't supported on Android phones. So, I tried setting up local WiFi hotspots from my laptop to enable WiFi. But my phone doesn't detect that wireless network at all. My friend's Nokia E51 detects the hotspot, but not my HTC Desire. I tried detecting hotspots created from other laptops but the result remains the same. The E51 detects it but the Desire does not. Do I have to change some settings that I am unaware of?

View 4 Replies View RelatedMy SGS (well its actually my wife's but I use it also) will not connect to WiFi networks, other than the one we have at home. If we are out, the phone will be able to see lots of WiFi networks, but it cannot connect to any of them as it says the signal is poor. Other people can be sat right next to other with other phones and have no problem connecting and they have strong signals. At home it will connect, but even then there is only one bar of signal, even though the router is in the same room. It appears that the phone just cannot get a strong enough signal to connect.

However neither Super Manager or ASTRO will allow me to uninstall the crap ware on my phone. Is there something I'm missing? I followed all the steps at XDA.

View 2 Replies View RelatedI 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've installed custom android 2.2 to my phone Tmobile pusle mini (huawei u8110) and now i have no mobile network .It says unable to search for networks. I cannot post in that forum because of the restrictions to new users.
View 9 Replies View RelatedI got 2 Sprint HTC Heros 3 wks ago. They work fine with any WiFi network that shows up as available. Other WiFi networks are completely ignored and do not show up in the list of available networks. I installed WiFi Analyzer and it is also prevented from seeing the same "invisible" networks. One WiFi network which does not show up is my home network. Last weekend I was at a B&B in another state and had the same problem with their network. Their network was up and running and visible to other hardware but not to our Heros.
Our home WiFi router is a Linksys WRT110 running WPA-2 Personal AES. There typically are three devices on this network: 2 @ g and 1 @ n. I have seen other WPA-2 Personal networks show up as Available while traveling but have no idea what routers were used. I called Sprint support and eventually got to someone in Tech support who put me on hold after I explained the symptoms. 20 min later the call was dropped. So much for Sprint tech support .
I am initiating the design of an application that would require an Android phone to connect to another Android phone via Ad-Hoc networking with or w/o security. I would like to know if Android supports ad-hoc networking. I would also like to know what is the average range of the wifi signal from an Android handset point-to-point with no obstructions. I cannot find any information about this on the web.
View 10 Replies View RelatedI got the Hero on 3UK yesterday. As soon as I booted it up it found a number of wireless networks and I was able to connect to my BeBox with no problems. Later on last night and continuing today, it can't find any networks in range. It shows the BeBox as 'remembered' but not in range. Even tho I'm obviously sitting near it. I've rebooted the phone today and no change. I installed the Fonera application yesterday and thought it might be causing problems so disabled it and still the problem was there.

View 4 Replies View RelatedI started using WiFi exclusively at home and my office after reading about the benefits on here. I noticed a tremendous increase in battery life. But when I'm on WiFi at my gf's parents house, the battery drain isn't even about the same as 3G it seems like it is much worse. What could be causing this? The signal strength is often better at this location than home/office so that shouldn't be the problem.
