WIFI Authentication Issues

Hello,
I'm a happy G3 owner, D855, 3Gb/32GB International version. I rooted using IOroot successfully and have done 2 OTA updates since then, currently on 10g, root still on.
I'm having major issues when trying to connect to WIFI routers in cafes/restaurants/hotels, public places in general, whereas my wife's phone and my smartwatch (believe it or not, with its mini antenna in the wrist bands (Omate Truesmart)) connects from the first try.
On the G3, I get "Authentication error" almost always, but it is working properly at my home, my parents house etc.. Only in public places or rather in places where there are a lot of people connected usually.
Does anybody have an idea what to do to solve this issue?
Many thanks for any help/tips
Chris

I do not have same issue but very simillar. Everytime wanna connect to public wifi LG G3 Android 5.0 show up screen with "login into network". Nothing more. Web browser won´t open page with login name and password even own web browser is not openning anyway. It works before Lollipop arrived...

I have the same problem, do you solve it?

You could disable "Show passwords" (Settings / Security) and try again. For some people this appears to work :good:

[Q] How to connect to hidden WiFi?

Hello xda community!
I have a strange and serious problem: I can't connect to hidden WiFi's.
I'm with a LG G3 D855 10H (no newer versions available).
At work we use a hidden WiFi without password but with Juniper VPN.
When I type in the network name and save it, it tries one time to connect, then my LG G3 shows "not in range". After a few seconds, the WiFi is on the top again with a very good signal.
When I try to connect again, it shows "not in range" again and so on.
I tried it at home and created a hidden network and it was reproducible.
Anyone else has problem with this?
Many thanks in advance for your help!
Best regards,
Jake

Now that is what you call a 'special' post!
Would you care to explain how it was resolved for the people that have the problem.

My problem still exists, but isn't urgent anymore.
I found out, Android itself have problems (or restrictions?) to hidden WiFi networks.
I also found an app names HiddenSSID Enabler, but it seems it didn't work for me (or G3?).
If someone has a solution it still would be very helpful fo rme and the rest of the community.

I have logs posted in my first post, WIFI DESTROYED TWICE or there abouts.
I've had to resort to DATA and its killing me haha i think i am getting close to fixing it, well i think i may be closer than you two and can one of you kindly take the lead as im reinstalling windows and i haven't gamed in 6 days :|
/system/etc/wifi/WCNSS_qcomcfg.ini
then the problem is complex but i am sure it is something to do with gEnableApProt=1
Offshoot fix, reinstall using googled imei number that doesn't have a flag or some how fix the flag <READ A FEW DAYS BACK>
I think actually the program that stuffed me was Airmon by maxters. It asked me if i was pro and of course, i said yes. Who would simply click no? I know a ninj wouldn't click no. I think there is a manual reinstall to link to it again i find the modem in its own partition having a chill, most likely trojan/backdoor and pwning everything around me.. I had three encrypted vpn backdoors and escalated accounts on my computer I paid the 5$ for the binarys, i think i paid 5$ for the back doors.
Not to sell Airmon out though.. Rooting our phones and accessing countless forums and websites really does leave us rather "xposed" some other cuplrits may be dsploit, ROM manager, linux Deploy/kali, Pamn IP scanner, system app remover pro, busybox pro's (Stephen/JRummy) or CMinstall/accessing the forums and trying to install cynagenmod / twrp recovery. I'm probably going to go with..... Airmon/Linuxdeploy or uninstalltool. But may have just been my IP logged and i hit a booby trap script along the way.
You guys done anything of the sort?

Neither I understand what you are talking about, nor am I (as not native english speaker) good at "sentence guessing".
I have a rooted phone - of course.
But I'm pretty sure my WiFi is not destroyed...

Connects to Guest Networks

Hello,
I have a Samsung Galaxy Note 2, SGH-M317i (Bell Mobility) and recently installed Cyanogenmod 12.1 (Lollipop 5.1.1). All is running well, the device actually seems to be running much faster...probably due to the lack of bloatware that originally came with it. Sure, I miss some of the "cool" features that the manufacturer had added (ie. hand swipe for screen capture), but overall I am extremely happy with the decision to flash the ROM. Although it does self-identify as a SGH-N7105 now. (About Phone > Device model)
Anyway, I have noticed that when I have my guest networks enabled on my home router (an ASUS RT-N66U running the latest Merlin firmware), my phone insists on connecting to the Guest networks (a2.4 and 5 GHz) instead of my full, "regular" network (hidden SSID, but a "Saved" network in the phone). Even if I go into the WiFi settings and tell the phone to forget those entries, it will still try to connect...even going so far as to say "connected" even though I know it does not have the proper credentials. I have no idea what is causing this as the problem was not present on the stock 4.4.2 KitKat that I had previously.
Sure, I could give it the credentials for those guest networks (all are WPA-Personal protected) but I have restricted those from accessing the intranet as they are primarily for guests who come by, so that is not really a viable option.
Does anyone have any suggestions? It seems strange that it attempts to connect and save these networks, so technically, I shouldn't have to do anything to keep the phone from connecting. However, since it insists, I had thought that Android would have a native (not requiring an app) method of blacklisting these networks. I have looked at apps such as WiFi Ruler, but again would've thought that there is a manual way of doing this. (I don't know if this is obvious by virtue of the fact that I am running a custom ROM, but the phone is rooted.)
Thanks!

used this code and off your wifi power saving mode and try *#0011# select wifi..u may need need press the botom left button to select wifi

Very odd. It seems that since installing CM12.1, my device no longer accepts or recognizes USSD codes. I guess I hadn't noticed since I had rooted and unlocked it prior to flashing Cyanogenmod over the stock ROM. I did some reading and I found that there is a patch to enable those codes (and SMS) on CDMA models of the Note 2. However, mine is LTE and does SMS, MMS, and it uses LTE without issue.
Here is a link to that page:
http://forum.cyanogenmod.org/topic/112400-solution-to-sms-and-ussd-code-on-cm121-cm12-cm11-cm10/
Is this something anyone else has experienced? Should I follow the instructions on that page and install the patch?
Again, my phone is a Samsung Galaxy Note 2, SGH-i317M but since the installation of CM12.1 the About Phone > Device model reports it as being a GT-N7105 with a Baseband Version I317MVLUDNH2.
I'd really like to try the solution to my WiFi problem, so if anyone else has had experience with the USSD codes not working please let me know if there is a solution.
Thanks!

To update my last post:
Some USSD codes do work, I watched the pop ups more closely this time and there is one before the "...invalid MMI code" that says "USSD code running". The main one that find interesting no longer works is the one I had used to unlock my phone *#197328640#. I had figured that it would not have disappeared simply by installing Cyanogenmod. Further, I also followed that thread I had posted the link to a little further, and I'm not comfortable flashing the "patch" it leads to as I cannot confirm it's original source and it does sound like it may be another full ROM.

No connection to several website/services via LTE when DUAL-SIM active

Hi,
I love this phone, but one point drives me crazy.
When I have 2 SIM enabled, and logged in to LTE network, I can't open several websites (ex. threema.ch).
When only one SIM is active, all is fine. As well when I'm logged in to WiFi.
As well when 3G is active, all is working.
When I use the phone as HotSpot, I can access the website via laptop.
Therefore the LTE connection is not the problem.
Can someone please try the same with his SIM and report back?
Thanks in advance
BR

I can confirm exactly the same behaviour with LTE over Telekom DE and o2 DE.
Unfortunately, I don't have a solution other than switching on VPN now an then to receive new Threema messages.
Sony recommends to repair the system software (make a backup in advance) via the Companion software, but I haven't tested that yet.

Thanks for testing. I don't think that repair of system software will fix the issue.
I already tried with installing FW from different Region, what is this in principle.
No improvement.

The Sony support told me that the issue also exists for WhatsApp (which I use rarely so I can't really confirm that), so I hope the issue will get a higher priority.
My bug report with Threema's stack trace and so on was forwarded to Sony's dev team. Let's hope for the best.
I get mixed results for wifi tethering. Connected Android devices and an iPhone I tested won't connect to threema.ch, but a Windows 10 notebook does. Can you confirm that?

Yes, I can confirm.
I only tested tethering with a Win10 Laptop. Threema.ch was ok.
There are now a lot of messages as well in the Sony support forum.
As well I had issues with streaming from Netflix. But after the update yesterday this wa fixed.
I expect the priority of Netflix is even higher then for Threema

Hi,
Did sony confirm the problem with two SIM?
On the Sony support site, only message from users confirming the problem:
https://talk.sonymobile.com/t5/Xperia-XZ2-Compact/Issue-4g-mobile-internet-with-2-SIM-in-my-xz2c/td-p/1314928/page/3
Local support does not confirm the problem at all...
I hope the problem with two SIM will be fix soon, but for now I don't have any information from Sony that they are working on a fix it
Thanks

Sony confirmed in an email that the issue is also known for WhatsApp and that the support is waiting for feedback from their dev team.

This gives hope for a quick solution
Thanks for the info

After update software to version 51.1.A.4.225 the issue has been fixed

Anyone w/S7 Active on Red Pocket? Mobile hotspot & tethering just broke

Hello all,
I was warned of an impending "update" a few nights ago. Since it hit, my mobile hotspot no longer works.
Does anyone else have an S7 Active on Red Pocket who has a working hotspot? If so, could you share the APN settings you are using, and the Android version you are on?
I think they rolled me back to January 2018. G891AUCU2BRB5
Would rather not factory reset or root, but getting very close to doing so. Neither RP or AT&T are helpful here.
Thank you,
Bob

Red Pocket Mobile Hotspot problem solved - stock Oreo 8.0 fixed it
Well, for anyone who might encounter this, I finally resolved it.
Pulled the SIM card and did a factory reset. Then it recognized the Oreo update over Wifi. Had to load an intermediate update first.
I put it Red Pocket's AP settings.
First time I tried Mobile Hotspot, it still didn't work.
Restarted the phone.
Still didn't work.
Then I remembered one rep saying to switch MVNO type to "IMSI".
3rd times a charm. Hotspot and USB tether now both working.
After ten hours of wading through poor advice, I'm back to where I was four days ago.
With one exception: I learned how to turn on Developer Mode (tap Build Number 7 times in Software Info)
AND SHUT OFF THE AUTOMATIC UPDATES UNDER DEVELOPER MODE SO IT WON'T HAPPEN AGAIN!!!

I have a stock S7 Active/G891A that I bought unlocked on eBay in March of 2018. It's currently running Oreo 8.0.0, build G891AUCS4CSA3. I just now disabled OTA updates thanks to you.
I've been trying to get Mobile Hotspot to work on this phone ever since I switched Consumer Cellular several months ago. Whenever I tried to enable hotspotting the phone screen would display a popup:
Please wait while verifying
Which was a normal message on the AT&T network, but now (using AT&T's network through Consumer Cellular), after 5-10 seconds a different window would appear:
Tethering/Mobile AP is unavailable.
A network issue may be preventing use of your Mobile Hotspot. Please call Customer Care at 611.
[excessive hard-coded line breaks omitted]
Over the course of several weeks in January I literally spent hours on the phone with several Consumer Cellular 1st and 2nd tier support techs trying to get past that error. Tier 2 support gave me new APN settings, had me do a network reset, and suggested that I do a factory reset. Which I did later, but that didn't work, either. Then CC tier 2 support gave up and bumped my ticket to tier 3. Tier 3 support then transmitted their version of an APN definition to my phone, but still no love. At the end of the 2nd week of phone tag, a Tier 2 tech told me that "it <Mobile Hotspot> just doesn't work with some phones not sold by us".
Maybe hotspotting won't work with my old Motorola Razor, but I was pretty sure that I'd eventually strike gold with my trusty G891A.
Because my S7 Active has version 4 of the boot loader (thank you, latest and final OTA), I haven't been able to find anything that resembles a working root. I even paid OneClickRoot to do it via remote desktop session, hoping that they had some good mojo that I hadn't yet discovered. But their support tech hit a wall, too, and ended up flashing my phone back to stock Oreo 8.0.0. They also refunded my purchase almost immediately which made me sort of happy but still sad that I had no Hotspot abilities.
While searching for possible workarounds (ROMS, root, mystical incantations) tonight I came across your posts:

So I followed your tip. I created a new APN definition and copied in all of the values from the CC Tier 3 definition . I then set Mobile virtual network operator type to imsi . This value was set to None in all in all of the other APN definitions on my phone.
I didn't even need to reboot the phone. I selected my new APN definition and enabled Mobile Hotspot. The first message about verifying came up. But then the phone didn't direct me to dial 611. Mobile Hotspot simply started working.
Thanks every so much for sharing this insight.

WOW! Thanks so much for posting this. I've been struggling for a couple of months to find a way to hotspot my two unlocked LG's (G6 and a G7) on Cricket and Consumer Cellular. This trick enabled hotspot/tether quickly and easily.
My apologies to Cricket and CC, for my unflattering thoughts about them. I assumed it was their issue! Not sure why these unlocked LG's are fidgety like this. We got a Moto X4 (Android One flavor) in the family, and it can hotspot with no tweaking.
BTW - I have a similar issue with call forwarding on the LG's. Can't enable it, get an error. But the Moto X4 has no problem on either of these AT&T MVNO's. Anyone have an easy answer for that? Thanks.

This doesn't answer the call forwarding question. I'm not sure who pushes OTA updates, but soon after my last post I got a notification that an my phone needed to be rebooted for an update to finish. This was after I (at least thought that I had) disabled automatic updates. After the update the hotspot feature no longer worked. I checked APN settings and found that the update had reset the APN MVNO type to NONE . I manually changed it back to imsi and it's been working ever since. I also made sure (twice with reboot in between) that automatic OTA Updates are disabled.
Although enabling/disabling these features seems to be problematic with AT&T MVNOs, what I find more curious is that techs at Consumer Cellular claim not to know how to fix them. Maybe that's true, or maybe that's what they are told to say.
Was it coincidence that I received an OTA update within days of making this change, or is the Big Brother with the Blue Death Star logo watching us so closely?
