Just recently (a week or two), when moving out and then back into range for saved Wifi connections (e.g., work and home), the system can't connect because there is an "Authentication problem."
I can resolve this fairly quickly by clicking on the access point and connecting, but if I don't realize it in time, my data plan kicks in and starts eating data.
Any ideas?
I'm on the DEV edition of Sense, but this wasn't a problem prior to a couple weeks ago. I'm thinking that an update is the culprit.

Hey guys,
I have a problem with my wifi...
Here is the before: Wifi works about 70% of the time, occasionally the connection would be dropped (as in "no network access", it still said it was connected).
Here is what then happened (in that order): Wanted to find a less crowded channel and installed Wifi Analyzer. Quickly decided that Channel 1 would be cool, browsed to the router configuration on the Desktop machine (LAN connection), changed the channel. Back to home on Android (don't remember whether via the home or back button). Into settings to see whether I would have to rescan or whether it would pick up the change of channel itself. It couldn't connect... It scans and attempts to connect, but doesn't
What I tried:
I restarted the Galaxy. Still couldn't connect.
Deleted the connection and re-entered the passphrase. Still couldn't connect.
Uninstalled Wifi Analyzer. Still couldn't connect.
Restarted device again. Still couldn't connect.
(At some point during all this, probably quite early, the Wifi symbol also stopped showing up in the status bar. Doesn't appear no matter whether Wifi is on or off)
Switched back to the channel I came from. To no avail
Switched of encryption on the Wifi. Still to no avail
Any ideas as to what might have happened and, more importantly, how to fix it? As I said the connection itself has never been the most reliable, but this is a different league
Thank you everyone!

If you haven't tried it yet, reset your router. That fixes the majority of Wi-Fi issues out there. If that doesn't work, it may be your router itself. Certain routers have more issues with mobile phones than others.
You may want to go to a friends house and try connecting to his router and see if you can troubleshoot and isolate the issue. Either way, best of luck...

Damn you sitecom router!!!
Alright, one thing I hadn't tried until now was to restart the router. That fixed everything including (for whatever reason) the lack of the Wifi symbol!!
So if that is possible feel free to delete this thread! I didn't find the option anywhere...
Sorry for the unjustified disturbance

Hey all,
I've had my Galaxy S II GT-i9100M for a bit more than two months now. It's been on ICS 4.0.3 since the first day I got it, and is unrooted.
Wifi was working fine the first month or so that I've had it. However, in the last month, while trying to connect to my university's networks from the wifi settings screen, it will display "connecting" for a long time, then change to "saved", without successfully connecting to the network. Odd thing is, if I turn the wifi on and off repeatedly, it may connect eventually, with around a 5-15% success rate each try. However, there's also a relatively high chance it will automatically disconnect itself within a few minutes.
The school has three main wifi networks: one is unsecured, while two are secured with exactly the same authentication methods (PEAP + MSCHAPv2) and takes the same login credentials. All three have the same problem when I try connecting. It's not a problem with signal strength, either, since my friends nearby can connect using their phone or laptop without any problems.
Here's what I've already tried to do to fix this:
Asked the school's IT helpdesk
Forget both secured networks so the phone can autoconnect to the unsecured one
Tried wifi diagnostic tools, such as Wifi Analyzer and Wifi Fixer, and tried changing to a better channel
Deselected "back up my data" in the Back Up and Reset settings screen, deleting existing wifi settings from Google's servers
Connect using a static IP address rather than DHCP. Either it has the same Connecting->Saved issue, or says something about "avoided a poor connection"
Did a factory reset, including wiping all user data
The wifi has no problems connecting to my home wireless network, and to most, though not all, other public networks I've tried (same problem as above if it doesn't work).
On a somewhat different note: there are two networks (each of which I've only connected to once at most) that are permanently saved on the list of access points; there's actually no way to forget/delete the network. They even survived the hard resets, and are listed before I link the phone to my Google account. Could this be related to the main issue above?
Is there a fix for this issue? Thanks in advance for any suggestions!
Hello everyone,
I'm a longtime lurker of XDA ever since I switched from my Palm Pre (RIP) to an HTC Evo 3D. I created an account finally to post this question and I'm hoping someone can help because I am at the end of my rope.
My Nexus 9 has a wifi issue that cripples my entire network. First, I'll give you the details of my configuration and the problems I'm running into:
Running an ASUS RT-AC66R on Centurylink DSL. I have tried both the 2.4 and 5GHz bands. I have tried multiple channels per band with no effect on the issues listed below. The 5GHz band is currently disabled.
Unless I am am running the factory image that came with the N9, my wifi connection will almost completely dry up across every device on the network when the N9 is connected. As far as I know, this only happens on my home network.
Restoring the N9 to factory settings - which I have now done twice since purchasing it on Nov 3 - eliminates this problem almost entirely until I install the OTA update. This problem happened with both the day one patch and persists in the recent update to 5.0.1.
If I am playing my PS4 or streaming Netflix (or anything that requires a connection), I notice the connection speed rapidly drops to somewhere in the range of 0-5 kb/s as soon as my N9 connects to the network. When I deactivate the N9's wifi, the connection returns to normal speed immediately.
I am still connected to the network when speeds are low, but data crawls. I am able to connect to the router's config page and can see that traffic caps out at about 5kb/s down and 60 kb/s up.
Here are some of the fixes I've attempted, which all failed to produce results:
resetting the router
resetting my modem
disconnecting all other devices
switching channels on the 2.4 and 5GHz bands manually
updating the firmware of the router
changing the network name
changing the network password
changing the network security type
I am typing this after having reset my N9 to factory settings for the second time to confirm that the issue lies within one of the firmware updates. Can someone please help a networking noob figure out how the connection of one device quickly (within 15 seconds) halts all traffic?
I should mention that the exact same issue was present on my N5 earlier this year (long before Lollipop arrived) but that it eventually worked itself out and stopped hijacking my network. Unfortunately without mobile data on my N9, it is essentially useless until I figure out the issue.
Thanks in advance for any help!
The first thing that came to mind is an ip conflict. Have you tried changing to a static ip on your nexus 9?
Edit: Also when your nexus 9 is connected check and make sure the ip address on your other devices jives w/ you router (you may need to make all devices static until you find the problem) I had the same router as you and i had a network switch that was throwing odd ip address to devices not even attached to it...
I updated to 5.0.1 again and didn't have any issues this time around. I went ahead and set a static IP anyways but I'll report back here if I have any issues. Thank you!
So I'm running my N6 as a de-googled Android (Lineage with no gapps), I was going through some settings on my Pi-Hole setup which is always running on my home server and decided to block google.com as I remove google from as much as I can and figured why not. Noticed a minute later my phone lost it's internet connection. Got the connected, with no internet msg. Did a couple of disconnect / reconnect and it didn't resolve. Then thought it may be the change with Pi-hole so I removed the block on google.com and the phone reconnected. So apparently my phone is doing something with Google as far as a connection even without a gapps package in there. Can anybody explain this to me?
Hi folks,
Weird thing happening to me while I'm out of the country on vacation. Being out of the country is probably irrelevant though.
I'm in a hotel that has crappy slow "captive portal" wifi. So, you connect to the SSID without password, and it redirects you to a login page (name/room number), then it provisions the device.
The wifi frequently hangs or disconnects here, and is super slow even when it is working, so I decided to bail and just use my phone's mobile data. So I went into Internet and turned off the wifi. Slid that switch to OFF.
Looked down an hour later when I had trouble connecting to a site and found the wifi was back on and connected to the hotel site. I turned it off again, but shortly the same thing happened again.
Eventually I turned off the other part, where it can scan in the background for improved location etc, and THAT seems to have stopped the problem, but why does the wifi keep turning on and connecting when I've explicitly switched it off?
Bug? Feature?
Bit of a guess... you are on data roaming? If roaming, I bet the phone is looking for "better options" if discovery is on, and it will re-connect if it finds a wifi that it can use. I'll go with buggy-feature.
