Xperia Z3 Compact Wifi Authentication problem

KMS98 — Sun, 15 Feb 2015 22:32:17 GMT

I just purchased the xperia z3 compact and am having issues connecting to wifi. It iinitally connects but then it says 'Authentication problem'. The password is correct and I don't have this problem with any other device. I need a solution that doesn't involve having to access the router. Does anybody know how to fix this?

Thanks.

Hi Jake, thanks for your reply.

A lot of the suggestions were to do with the router, which unfortunately i am unable to access as it is in my roomates room and she is on holiday and has locked her door. But all my other wifi deices are currently working wtith that router, including my boyfriends xperia z1 and I know that it is WiFi certified.

Poor signal? It actully is saying the signal is excellent, it just can't authenticate.

Connection drops? Yes, keep Wi-Fi on during sleep always is selected.

Can you please suggest anything else to try as I know the router works with wifi and I have the correct password. Resetting or changing the chanel isn't an option right now. And it is never an option anywhere else I use wifi – work, clients workplaces, cafes, library etc. Sorry, but I need a smartphone that can connect to any working wifi network with the correct password without having to touch the router, and I've never had trouble with any other device.

Thanks.

For authentication problem, there's really not much you can try on the phone but to make sure that you are entering the correct password.

Do you know if your room mate is using MAC-filter on her router? If so, you will not be able to connect even with the correct password as your phones MAC-address needs to be allowed on the router.

Do you have a Google account in your phone and if so, have you used that Google account in another phone before you got your Z3 Compact?

No, there is no MAC-filter on the router.

I do have a google account and yes, I was using it on my previous phone which was an iphone 4.

But you haven't used it in another Android device? You can check that under "Android" on https://www.google.com/settings/dashboard

Have you tried to forget the network by tapping and holding it under Settings -> WiFi and then tried to connect again?

KMS98 — Mon, 16 Feb 2015 12:01:18 GMT

No this is my first time using Android. I have removed my google accounts and anything google related from my old phone.

I have tried to forget and reconnect quite a few times now, and of course restarted the phone.

Here are some screenshots. You can see the strength is excellent, then when I connect at first it says 'Saved, secured with WPA2' but then after that it says 'Authentication failed'.

The VGV75..... network is my landlords which i have the pasword to, and that isn't working either. I'm not so worried about that because the signal has always been a bit weak, but other devices could at least connect to it.

Do you have access to a PC or a Mac? I would recommend that you try to repair the software in your phone using PC Companion or Bridge for Mac but please note that this will reset your phone and delete your data. When you then start the phone and set it up again, make sure to disable the option for backup & restore with Google when you add your account as it contains WiFi settings and to avoid any issue being restored.

If the issue should remain i recommend that you contact a service location or local support team for assistance with having your phone checked.

I've a similar problem to the OP.

My 6 month old sony xperia compact has been great but suddenly i get 'authentification problem' with my wifi. Only at home. The laptop still connects fine. I've checked the passwords are ok. Any ideas? the phone still connects to wifi elsewhere. It's pretty annoying.

I suspect it started after the upgrade to the latest firmware?

@miniver

Sorry to hear that.

We got a few reports of issues with WiFi and we are looking into this. But if it happens with a specific network only i also recommend that you check my previous posts in this thread. Have you used your Google account in any other Android device? It's possible that incorrect setting have been restored from a Google backup which can cause this issue.

Just chiming in to say that I have seen this since the recent update as well. I have reset wifi settings and disabled Google backup & sync, with no change. Some access points that worked before the update, like those at my work, simply won't connect [the AP just says "saved" in wifi settings, or occasionaly "authentication problem"]. And frequently when I come home, my home AP will be listed as "disabled," and then if I manually ask it to connect, it works fine.

Something definitely changed in the latest update.

Hi Everyone,

I experience the same trouble with the wifi on my z3 compact sinci I upgrade to lolipop. The wifi connection works fine at my home. It does not work at my office, the phone says "save" and then "Authentification failed" (or something like that...). By the way, with my previous xperia Go, I was connected to my office wifi (and I used my google acount..), so maybe I have the problem mentionned previously about the seting which have probably been stored into my google acount. I tried to find something, but I did not find anything.

Thanks to Sony to fix this bug (probably due to lolipop) quickly because I use this phone for my work and I need the wifi at the office.

Best regards

peter

I am still having problem even using Bridge for Mac, resetting the phone without checking the Backup and Restore option.

Every morning I wake up the Wifi is disconnected with the message "Authentication Problem".

Is there any fix for this?

Hi All just got my phone and had the same issue tried everything posted all over the web strange thing was when i turned the

Wi-Fi security off it connected but i was not willing to leave myself open to attacks.

After hours of reseting the phone the router and trying loads of different configurations i noticed something on the phone

while looking for the Mac address i went to advanced on the wi-fi screen (on the phone) and selected the Auto IP support

Right down at the bottom and what do you know I am now connected go figure hope this helps others with this issue.

I had similar problem, my phone had a little problem with authentication and regular disconnecting from wifi. I tried many things like hard reset, software update, router software update etc. even I came back from Marshmallow to Lollipop for a while, but nothing helped me. The solution turned out to be channel in my router. I changed it to 3 after that to 13 - but my phone works only with default channels like 6 or 8. After change my wifi get back to life and now work perfectly. Try it in your case

Channel - This field determines which operating frequency will be used. It is not necessary to change the wireless channel unless you notice interference problems with another nearby access point.

Hi Rickard,

I'm adding to this post because my problem is similar, except that: every time I restart my phone (power off and back on) it asks me to 'authenticate' with my Google password. That is fine, except that I have to be in a wifi environment to be able to do that. If I'm out of wifi, it will be 'loading' for ever and I can't use my phone any more.. until I find a hotspot.

This is new. I didn't use to have that before, so maybe it's something I did. I hope you can help. Thanks!
