[Q] Wifi keeps getting stuck on "authenticating"

Pretty much every time I try to connect to my home wifi, it keeps getting stuck on authenticating then it will fail and do it over again and again until it says network disabled, poor connection, even though it has a full 4 bars... I've tried turning it off and back on, I've tried forgetting it and redoing it, I've tried restarting the phone.. The only thing that seems to work is for me to unplug my router and plug it back in while leaving the wifi on my phone on. When the router boots back up, then my phone will connect. I would say it's something wrong with my router, but my other phone has absolutely no problem connecting.
Any help would be appreciated. Thanks
Edit: Oh yeah, the phone WILL connect if I turn the password off on my router. I am 100% sure I'm putting the correct password in on my phone, I've checked it numerous times, plus as I said, the phone will connect if I reboot the router every single time I want to connect, so the password is definitely correct.

Originally I was using the stock ROM on 4.0.4, now I'm using the most current CM9 nightly. Have the same problem on both ROMs.

Found a solution, set up my router so that the security is disabled, but so that only the mac addresses I allow can get through. Works perfect and no loss of security.

One could easily listen on your network to scrape your MAC address, and then spoof it. I suppose one could brute-force WPA encryption too, but it's much harder.

You can always just set a static ip. Tap and hold the wifi network and tap advanced and change dhcp to static and go on your pc and find your ip by launching cmd and enter ipconfig. Then enter the info cmd gives you onto your phone but to avoid ip conflicts just change the end of the ip address to something else like 84 no devices usually use that.

Ive seen that issue attempting to connect to my own wifi a couple of times, and in every case it was caused by the wrong PW. I would reset the PW on your router so you know exactly what it is. they are case-sensitive so it could be that you mistyped a letter or two on either the router or your phone. you should also be able to connect using WDS iirc, assuming the router supports it (most newer routers do)

[Expert advice needed] [HELP Reqd] Wifi connecting but not working...why?

I updated my HOX to ViperX JB with hBoot 1.31.
But now, it connects to WiFi router but the internet doesnt work. It works sometimes, else the internet is not working. I tried on another router at a different place, but it is not working. Also i updated hBoot to official 1.39 also, but the problem persists. Restarting the router several times and clean install of the rom didnt help. The boot.img is also from the same rom and all else works fine . What could be the problem? please someone guide me.
After a few posts down, there is another person with same issue.....

i have had similar issues since moving to official JB and HTC aren't that helpful, just say must factory reset the device and see what happens - have now installed viper 3.3.1 and get the same problem - never had the problem when i was on ics - get full signal - and using wifi analyser also shows full - tried on 2.4ghz and 5ghz - it just wants to stop transferring data - if i disable wifi and reset it then it works fine for a while before no data transfer again
i've even re-configured one of my access points with a different name and set the phone to auto-switch to strongest signal, but that don't work either

i'm still in discussion with HTC on this - i purchased my phone in May 2012 and it wasn't until late June that HTC acknowledged the problem

Some routers will give you a bit of **** when trying to connect to them, had a similar issue when trying to connect to my Belkin N at home and fixed by:
1.Open command prompt on your notebook that is connected to your wireless network and type "ipconfig/all"
2.Make a note of your Default Gateway ie 192.xxx,.x.x
3. On your HOX whilst connected to your wireless network go into settings press on wifi.
3.Long press on your wireless network name.
4.select modify network and select "show advanced options"
5.Make sure "none" is selected in proxy settings.
6.Make sure "static" is selected in ip settings.
7.The default gateway you noted should be entered into IP address on your phone however change the last number so if the last number is 2 change it to a 3 to keep in your routers address range.(Make sure it isnt the same as DNS 2 on your phone)
7.Enter the Default Gateway you noted in gateway on your phone as is.
8.Set network prefix length to 24.
9.In DNS 1 on your phone enter the Default Gateway address you noted as is.
10.In DNS 2 on your phone enter the Default gateway settings you noted however the last number should be changed to the following number so if the number is a 2 change to a 3.

I am having the exact same issue, was having it with ICS too! However i think its router dependant because here in my apartment in finland i get the issue, but back home on my router at home it doesn't happen at all! Its definately not a hardware problem it has something to do with software or configuration. Is there an official bug identified by HTC that we can track or something? Its so annoying having to disable wifi cause you know if you leave it enabled you won't get whatsapp notifications after a while
oh also for the record the same router that my OneX stops sending/receiving data from has no issues with my older desire HD, wifi works on it perfectly

@mathrania, Thank you for opening the thread. i have the same problem of yours and we live in the same city!
@all
I have the same exact problem of the OP's.
WiFi has perfect signal, Perfectly connected but data transfer just does not happen. I need to turn WiFi Off and then ON to get the connection working and then in a minute the problem comes back!
I am running stock JB 4.1.1 and my phone's mother board has been recently changed last week by HTC.
Adding to this JB 4.1.1 does not connect to Enterprise networks which is a well known issue in android 4.1.1 which makes me unable to connect my phone in office... so it's like completely un usable wifi.

I may not completely agree that it is a router issue because i have my nexus 7 which in-fact helped me to identify that my phone suffers a problem.
Even my Sony Xperia Arc works fine..

Yes it definitely is annoying, i too had the same issue with ICS ... but i took it so seriously, it was my nexus 7 which made me realize that i have a problem.. the notifications were there on the N7 and the HOX slept nicely without anything :-/
The service center before replacing my motherboard claimed that it works fine. i would not agree and sent it back, i had an unlocked bootloader and they took special approval to change the motherboard and still the same problem!

Thanks for the advise.. i would definitely love to have a solution for the issue. If i remember correctly i had the problem even on my office network.. in other words, was just wondering if you had the problem in all networks ?
Again to make the issue more clear, the WiFi gets connected, however the data transfer dies in sometime, at the same point of time the signals are clear and strong.
i can be 100% sure that this issue is not the same as the famous manufacturing issue with HTC one X as i got my motherboard replaced last week for the same problem and still face the issue.

i should say that this problem has become more evident after the Jelly bean update. I think back and recollect that this problem was there in ICS but in Jelly bean it is noticeable very easily.

I believe your right that you have a different issue to the infamous grip of life wifi issue.
If you did suffer the grip of life problem you would struggle getting a connection with your/any router, (unless you squeezed your phone) you don't struggle connecting to the router so don't do the "squeeze test" or it could damage the phone further.
I'm no expert with your issue, but if it happens on stock rom then it could be hardware related, but you already know this.
Best of luck and sorry I can't help further.

Thanks, no problems.. i am going to record a video to get the problem across to HTC and our forums for help

pretty sure its not hardware related because it doesn't happen on all routers/networks. If you've only tested it on one or two then try on a couple others and see. for me it only occurs on one or two out of about a dozen wifi networks

Cannot connect to WiFi

Is anyone else having issues connecting to wifi? When I try to connect to wifi at my house, I get a pop-up error saying "AP currently not in use. Internet connection slow." If I click retry, it comes up again. If I click cancel, it says "Failed to obtain IP" and is not connected.
I have tried restarting my model/router with no luck. My Note 3, laptop, and other devices have no problem connecting to this wifi network...

I had a problem with wifi,but sounds different then your issue.Mine would just disable after obtaining ip.Samsung rep at best buy reflashed phone.That saved all data and apps.AND,it fixed wifi.If you can't work thru your issue,go to best buy or att store and get it reflashed.Cant hurt.
Good luck.

OK, so went to the ATT store today and they reflashed my phone. Got home just now and tried to connect to wifi, same issue
Is anyone else having this problem?

Fixed it.
SOLUTION: I changed my router encryption type from WEP to WPA and now it works no problem

Try rebooting your router, I had the same issue the first day I got mine and a reboot fixed it.

No go for me I just Got my N4 from Verizon last monday and having the same issue u had. I changed my encryption from wep to wap and still same problem. Ima go to a verizon store and see if the "reflash" the phone like some suggest here. Might help my problem

Hi all,
I also experience the same issue from time to time. I have this happen on both my home network (WPA2-Personal) and work (WPA2-Enterprise). My fix is to either reboot the phone or activate Airplane Mode for about 20 seconds and then disable Airplane Mode. After doing that, wifi picks right up for me. YMMV.
I can try to get the exact error log messages from our networking technician at work if it would be helpful to anyone.
Out of curiosity, do any of you have other peripherals connected at the time you experience the issue (Pebble Watch, etc.)?

Same issue
With my GN4, I can connect to my home WIFI no problem and my GF's WIFI no problem but when I go to my Dad's, I CANNOT connect to his WIFI (Netgear WTG624v3) but both of my sisters with a Samsung Tab 3 and Samsung S4 CAN connect to my Dad's WIFI. It's really aggravating. Basically, when I try to connect, it says "connecting" "saved" Then it says "scanning", and says "connecting" "saved" again and again ..... But never connects.
I have tried changing just about every WIFI setting on his router including resetting the router. Tried removing the encryption making an "Open" network and STILL can't connect... and tried every encryption type provided and still nothing. I set the dynamic address range from .4 to .254 (on router) so I could try connecting with a static address to 192.168.1.2 / .3 and still nothing. I tried removing my GN4 browser cache, and setting it to airplane mode(20 secs)... nothing.
I'm at a loss.. given that both of my sisters with two different devices can connect to my Dad's WIFI but I can't with my GN4? But I can connect my GN4 to other WIFI networks, no prob.
UPDATE: Next, I will try downgrading the firmware version on the router to an earlier version. Hopefully, that's the solution. I will report my findings here.

Downgrading or using an older Firmware version for this Netgear WTG624v3 router DID THE TRICK!
If anyone else is having the inability to log into a WIFI router, try installing an older router Firmware version. I got the idea from here:

Can someone please help me with DNS?

I had many phones and I had many troubles with DNS. Now it is the G4. It seems DNS just stops working sometimes. YouTube just cuts, webpages cannot resolve DNS address. I have to disable WiFi and then enable again to get webpages/internet to work again. When DNS stops working the phones works hard and gets hot and drains battery like hell. I had this problem with Samsung phones too.
It's not my router or internet connection because everything else works (my computers and servers) and I have changes routers many times.
Is this android? WiFi drivers? As i said, it cannot be my network. I use google DNS 8.8.8.8/8.8.4.4. I have also tried static IP/DNS address.
This I had with others phones too. Never apple phones though... So it seems like an android problem? Of course I have tried resetting my phone and reinstalling.
Anyone with any useful tips or solutions here? Getting tired of this problem...

How are you setting DNS?

By dhcp. I also used static dns.

Why are you using static DNS? Are you by any chance using a DNS to bypass geolocation? Are any other devices connected to the WiFi having the same issues? This looks a little bit like an issue that is independent of the G4. When you are setting up a static DNS, it may conflict with the other settings. I am using the DNS from the Internet provider, I am not touching any settings for WiFi and I never had issues unless the Internet connection itself had issues (like last week with the DDoS attack from the IoT devices). Maybe it is an issue with your Internet provider.

I use dhcp, but have tried with static. The only thing that hasn't changed is my provider, but as I said, everything else is working except my g4. Same with my Samsung s5, note 3.

There is a "Network settings reset" in Settings -> Backup & reset. Try it. If you can update to a newer version, do it, it will clear Dalvik Cache. I think there is something wrong with one of the system apps. If your G4 is rooted, then just clear Dalvik Cache from TWRP. I would also delete the WiFi AP and reconnect. Did you check the router for the IP it gives the G4? Maybe there is a conflict with another device, if you're setting IPs using MAC address.

Tried all that. Reinstalled the phone several times by the way.
My router gives IP adresses to all my devies and thats a lot og devices. If there is a conflict you know right away and more the other devices who is conflicting will also not work. Every other device works except my G4 UNTIL i disable wifi and then enable it, like within 5 second. Just disable and enable wifi and everything is back to normal.

Never fixed the issues with those two phones... just had to live with it disabling wifi and enabling again... several times a day. Sometimes after a short while and sometimes after a longer time.

Then I would say that it is not a problem with the phone, maybe with Android. What exact model is the router?

Yeah it has to be a problem with android VS my internet router perhaps. It's weird because I've been through jellybean -> marshmallow.. My internet provider router is Norwegian one (inteno something).
My network:
internet -> internet provider router (inteno) -> ASUS RT-AC68U as access point -> phone.
IP adresses is recieved by the inteno router.
So maybe my phones don't like the internet provider router. Will have to test more when I get fiber internet with a brand new router.

How u change it i know in

This is how I do it on my Note10+. Turn on wifi at location you can't connect to. Open Settings, go to Connections, click on the name of the wifi connection then click on the gear icon. Go to the bottom where it says Advanced, click on that. At the top it should show DHCP with a little arrow pointing down next to it, click on that. Now you should have another option Static, click on that. Now scroll down to where it shows DNS1 and DNS2. Click on the DNS1 line, now delete the current set of numbers by tapping at the end of the last number and use the back button on keyboard. As you get to the end you should see 8.8.8.8 already there but grayed out. Manually type in 8.8.8.8, now do the same for DNS2 line, the numbers 8.8.4.4 will show the same way as line DNS1 did all grayed out. Manually type in those numbers 8.8.4.4. MAKE SURE YOU HIT THE SAVE OPTION AT THE BOTTOM AFTER YOU ARE DONE! Reboot phone and try to connect again. Now this worked for me, not sure in your situation. To go back to original settings do the first part but click on DHCP then SAVE at the bottom. This is NOT a guarantee it will work, this is what I did to connect at work. Personally I have kept it like this so every connection is Static using 8.8.8.8 and 8.8.4.4 these are actually Googles DNS server numbers I believe. If this helps then great if not sorry.

Click on the DNS1 line, now delete the current set of numbers by tapping at the end of the last number and use the back button on keyboard. As you get to the end you should see 8.8.8.8 already there but grayed out. Manually type in 8.8.8.8, now do the same for DNS2 line, the numbers 8.8.4.4 will show the same way as line DNS1 did all grayed out. Manually type in those numbers 8.8.4.4. MAKE SURE YOU HIT THE SAVE OPTION AT THE BOTTOM AFTER YOU ARE DONE! Reboot phone and try to connect again. Now this worked for me, not sure in your situation. To go back to original settings do the first part but click on DHCP then SAVE at the bottom. This is NOT a guarantee it will work, this is what I did to connect at work. Personally I have kept it like this so every connection is Static using 8.8.8.8 and 8.8.4.4 these are actually Googles DNS server numbers I believe. If this helps then great if not sorry.
