General :: Can't Connect To Any Public WiFi Suddenly
Aug 21, 2012
I had used some public wifis in mc donalds and airport in the past. I never had any problems. Yes, some required sms verifications, but anyways, my phone could connect to them.
After a month, i went to the airport and mc donalds again, but i cant connect to any of them. There were hotspots in other places as well, run by different telecom companies. all of them were open networks. but i just cant connect. I can still connect to my home WiFi.
Its not a ROM issue. i have tried several ROMs. I have never changed my baseband, mac address or anything like that.
Is it possible that my hardware is damaged? (but i can connect to my home wifi, which is also open) Or my mac address/phone number is "globally blocked"? (i had tried hotspots of different telecom companies. nd i dont know if theres a way to get my phone number by just trying to connect to a WiFi) Or have they installed something like "connect only with laptops"? does anything like that exist?

I've had a Galaxy Tab for 2 years, and used it, very successfully, as a wifi hotspot from May until July this year, when my laptop was suddenly not able to connect to the internet via the hotspot. It connected just fine to the Tab, and has no problems on my home wifi. The Tab was still able to connect to the internet normally, with no apparent problems.
I fiddled about a bit and thought perhaps it was a hardware problem, so bought a seconhand Nexus S. That has been working fine until yesterday, when the exact same thing has happened - the laptop can connect fine to the Nexus, but says there is no internet connection. The Nexus itself is connecting just fine.
I'm in the UK - my carrier is Three (Hutchinson).

Q2. Gmail etc sites are blocked in WiFi , is there any app which can browse to these URL's.

My laptop has 3 security levels for when using WiFi. For a home WiFi the least secure and a public WiFi the most secure. I'm using a public WiFi now and have searched my tablet settings for those sort of options, but can't find anything.

So, this happened suddenly. I was able to get my Nexus 7 connected via bluetooth to my Galaxy S3. Now, it just won't. It'll get on the paired devices list, but won't connect.

I am using a Mac with Eclipse Galileo, trying to load Android code from a public repository. I tried 'Checkout from SVN' and the URL is:
http://secrets-for-android.googlecode.com/svn/trunk/secrets-for-android-read-only
This is from the website:
http://code.google.com/p/secrets-for-android/source/checkout
I get the error:
Error validating location: "org.tigris.subversion.javahl.ClientException: Bad URL passed to RA layer
svn: URL 'http://secrets-for-android.googlecode.com/svn/trunk/secrets-for-android-read-only' non-existent in revision 114"
Keep location anyway?
I'm currently using this svn client in Eclipse to manage my own secure repository on another website, so I know it's installed correctly and works.

This is my first Android phone so I might just not know what I am doing. At work we have an open wi-fi network for patients and visitors to connect to. When they connect for the first time they are automatically re-directed to a sign on page where they must provide their e-mail address. After that they are free to use wireless internet services. My EVO will not re-direct to the page. When I tried it on a friends iPhone it worked just fine. My phone has not been rooted and i have tried both the default browser and two that I downloaded from the market. The phone is connecting to the WiFi and getting a strong signal.

Didn't do anything different. All of a sudden it stopped working. It sees it and connects to it, but can't browse the web or update from other apps, etc. Rebooted phone and told it to "forget" my connection and reset it. Nothing helped. Other computers in the house connect fine.

I've experienced quite a lot of problems with the WiFi after updating the Andriod. Everytime I try to connect to my home-network i get that it failed to connect.
The phone didn't have any problems with this before the update.
Anyone had the same kind of problem, or anyone that has a smart fix for it?

We have 4 android phones at our house (2 HTC Wildfires and 2 HTC Arias). All four phones have been working flawlessly with the home wifi. Until today. For no reason at all, none of the phones will connect to the wifi. Nothing has changed. The phones have not been updated, the we haven't touched the router or the modem. Just to double check that the password hadn't been hacked, I fired up my laptop, and it's working great. The phones will "see" the signal, and report that it's excellent, they just won't connect.
I've tried battery pulls, recycling the wifi setting on the phones, resetting the router, changing the security type, double and triple checking passwords, and the only thing that would allow them to connect was to remove all security from my router and make it an open network. They connected to that just fine, but it's not something I'm comfortable leaving.

I've been struggling with wifi on my Droid Pro for a while now. I tried Wifi Fixer, forgetting networks, even resetting to factory. When I try to connect to an open network, it says obtaining up, remembered, connecting, then disabled. When I connect to closed networks, it works for a while thence wifi becomes ed and goes off and on over and over. Sometimes turning my phone off and on again. Most times it doesn't.

Interesting issue. I recently set up a repeater in my house to boost my router signal. I assigned the same ssid and wep key as my router to the repeater. Since it's been connected I can't connect to the internet from my LG Optimus S while wi-fi is on--it says page can't be displayed. I'm definitely connected to my home network. When I disable wi-fi I connect easily with 3g. Did I configure the repeater incorrectly, or is it an issue with the phone settings.

We have those ShawOpen wifi network around town.
So here is the problem, when I go around town. My phone will connect to the wifi network around town. It will keep connecting and disconnecting to the wifi and data network. Making my IP phone and IM apps act weird.
Is there anyway to keep both wifi and 4g data on at the same time. I know the old app superpower on xda does it on some roms. but doesnt work on stock Razr HD.
BTW I have a Motorola Razr HD stock 4.1.2 canadian rom (rogers) rooted.

I haven't been able to get my phone to connect to wifi - any wifi, not just my home wifi - since the middle of August. I don't have any sort of data plan, just the basic texting-and-minutes dealio. This is what happens at the Wifi Settings screen:
- It says it's scanning
- It tries to auto-connect to my home wifi
- It says 'authenticating with (my home wifi)'
- After a few seconds it says 'disconnected'
- My home wifi in the Wifi Networks section of the screen is listed as 'disabled'.
- The process starts all over again.
As I said this has been like this since August, but it was never a problem before. I really don't want to buy a new phone. I need to get this sorted out in less than five days, so hit me with everything you got, even if it's not likely.
Info that might be useful (I don't know phones very well):
- Android version is 2.2.2
- Baseband version is I5510UGKC5
- Build number is FROYO.UGKC5
- My wifi is Motorola with Eastlink
Also I've had a problem with the app store for months...relevant? And: I used to have data but I switched my plan...never heard of a plan that didn't include WIFI though, good grief. And: my 'battery use' panel says Wifi only accounts for 3%...I seem to remember this should be way higher, if it were connected at all.

I've had my Samsumg S4 mini for four months now and everything was perfectly fine.I've been able to connect to the WI-FI at home but now it just keeps saying 'authentication error'.I restarted my phone several times, 'forgotten' the WI-FI and re-entered the password but it still does not connect to the WI-FI.

My WiFi appears to be going gray but, instead of being unable to browse the internet like most of the threads I've seen here regarding gray wifi icon, I can actually do internet-related things quite fine. I'm using the MiniCMSandwich Lite rom.

How possible would it be to make them connect with WiFi / Bluetooth? Have them both ring when a phone-call comes in and make it not matter which you pick up? Stay connected to the internet on both phones when one loses signal? (living on the border between Belgium and the Netherlands, when one has internet, the other one probably doesn't) Share audio with 1 Bluetooth headset? Do you know a way to make any of these happen?

Since I have installed the [ROM][4.2.2] Slim Bean - I9100G [Build v6.0] on my device (the Samsung Galaxy SII i9100g) I'm not longer able to connect to 5ghz wifi. The issue didn't disappear till now [Build v7.0].
The last 3 days I tried different routers and settings - but there was no improvement... My online research wasn't that successful, too - I only found a decription to a problem that sounds quite similar to my issue (at [ROM][GT-I9100G][JB][4.2.2] CyanogenMod 10.1): [URL]...

I have a problem with connecting to WiFi on android. I got 2 phones, one with Android 4.2.2 and the other with an older version, but none can't connect. I also tried with an iphone and had no problem.
Also, I tried connecting to other WiFi networks with the same phones, and they connected. So I think there might be a problem with my home network.

I have just bought an Android Smart TV Box (to replace my AC Ryan media box which gave up the ghost a few days ago) and it mostly works fine - it is connected to my tv via hdmi and the box is hard wired to my router - so it is the standard connection setup. I have two usb hard drives connected to it. I obviously want to drag and drop media files from my phone (android) or my laptop (Windows7) to the connected hard drives I use ES Explorer app on my phone and Windows explorer but using either version I cannot see the Android box wirelessly - if i do a scan using es explorer it finds the laptop straight away and i can drag and drop but it just will not find the android box at all. However if i go onto the Android box and into the es explorer app and do a scan it picks up the laptop and i can drag and drop a file onto the laptop. So the wireless is sort of working as opposed to not at all. But just seems odd that i cant see it at all - i cant even ping it from the laptop.
