Disable New WiFi Feature in Android 5.1.1

Hello Everyone,
I recently upgraded to CM 12.1 and discovered that my WiFi won't automatically connect to my router anymore if it doesn't detect access to the internet (I'm in China and Google is Blocked). I believe this explains why this is happening as there is internet and having to manually connect each time is annoying at least Is there a way to disable this "new feature" ?
Regards,
Bob

In Settings, got to WiFi, press the menu button in the top right and there should be an Advanced settings section or something similar (sometimes varies based on ROM/Language). Then untick the Avoid poor connection option. This should resolve your problem. If not, you may not have the correct firmware for 5.1.1

I already have Avoid poor connections unchecked. Any other way to fix this?

Does anyone have any ideas? Any help would be appreciated. Thanks

Try disable mobile data before connect to wifi, maybe this way should help

I have the EXACT same problem - it really does happen because you're in China and the method of internet access testing is through Google servers blocked in here.
I'm still trying to figure out how to disable the test or maybe reroute the destination.
It would definitely be a temporary solution to make the VPN active 24/7 if you put it on the router instead of on the phone / computer etc.
Let us know if you find a solution!

this was a very popular and general problem for every Chinese user with google service device.
you have to root your phone and manually change the google server address to a local substitute site, or just turn off the google server detect.
the easiest way is to use an APK developed by Chinese to have all these things done in a click.

came here with a google search. this problem is generic to later android versions. i'm on cyanogenmod 12.1 which is i gather is android 5.1.
looking at DNS logs, it tries to access: http://connectivitycheck.android.com - which redirects to google and fails as it's blocked by the GFW.
just downloading the chinese apk to fix it... the link to it i found is: http://m.hiapphere.com/apk-org.foxteam.noisyfox.noexclamation
EDIT: so now got noexclamation the app running, but not sure it's doing anything. UI is in chinese, not sure what options to deal with and how. anyone have success with it?
EDIT2: it's like this: install the app. leave it at defaults where it's using the developers website for connectivity check. toggle it ON if it's not already (i believe needs root). reset network settings by toggling airline mode ON/OFFl. you're good.
however - conceptually better fix would is to take the "feature" OUT, not alter the server that it's checking the accessibility of. from the chinese thread, i gather this will get done by:
su
settings put global captive_portal_detection_enabled 0
this seems to survive reboot as well. problem solved, end of monologue!

Wi-fi issue (and how to solve it!)

Received today (finally! :silly my XT1650-03 Dual SIM in white/gold flavour and... only few seconds after turning it on... the first issue!
And not a minor one, a bad issue... weird that nobody have reported it before!
Turned on, boot, chose language, selected a wifi and... error during verifying connection: no Internet!
Obviously, my wifi had a good Internet connection up & running...
Tried again. Nope. Tried my old phone in hot spot mode (ever worked fine with every piece of hardware...), connected... same error!
Major problem was that on this phone the verifying step can't be bypassed (ignore is gray out...), so I was on a no way loop.
After A LOT of tries, at last it decided to bypass and go after BUT all my wifi connection still were marked as "Connection without internet" and no navigation available.
I've tested three known good wireless connections, all open, all same result.
Tried to configure them as static IP, inserted good data (it's my work, I KNOW what to insert...), same result.
The phone was connected, was pingable, has good IP, Gateway, DNS but... No internet.
My old phone and my pc, in wifi on the same network, was laughing at new arrived while surfing the Web. ..
After some Google searching (and a LOT of stupid "solutions"...) I found the good one... :fingers-crossed:
It's needed to enable Developer options and, inside, enable an option called "Use old/Lollipop DHCP client".
After that we *have to* delete the memorized wifi connections and recreate them. After that they work fine!
Weird thing is that, when I set manually the connection parameters, there shouldn't be anymore a DHCP protocol to be used...!!!
BUT probably, since it seems to need connections to be deleted before begin to work fine on them, even with manual (correct!) parameters it continues to mark them as "No internet" for some strange reason...
I think this is an issue related to Marshmallow more than Moto Z itself, BUT anyway it is a bad bug and I can't understand @google what they have "invented" this time to have such an absurd behaviour on a simple (and old) protocol as DHCP!
Obviously, connection parameters before and after the setting were exactly the same (same IP, same gateway, same DNSs), BUT with old DHCP enabled they are now of Moto Z taste...
Nobody had faced this issue before?

I didn't have this, probably just you. Haven't heard of anyone else either, so i can assume it might be your Router/WiFi AP that is old/outdated and uses redundant/old protocols (try updating the Routers Firmware, see if that helps). If that isn't the case, then i don't know (maybe someone else also has/had this problem, don't ask me).

I have to repeat myself... It's my work... I know what I'm talking about...
Up to date, four tested, three not working vs. one working with new protocol enabled. All working with old one.
DHCP is a old, simple & efficient protocol, there is no need to mess up it...!
WiFi compatibility *must* be best as possible (think about public hotspots, airport, etc... I Travel a lot and I need it!) and not limited in any way by absurd changes in well working protocols...!
When I'll be @hong Kong airport and my Moto Z eventually refused to connected WiFi, what should I do? Ask them to "upgrade router firmware"?

If you Google "marshmallow dhcp client issues" it's full of thread of people having this issue...
What they have invented is still a mistery instead...

I don't have this problem too.
I have the phone from august. It is an UK model, single sim. I have done factory reset more than 5 times and never had that problem. It is your phone with this problem.

Great post. I have that problem to with wifi, cannot establish connection. Your guidance is perfect solution.
I guess is more to Marshmallow problem (software) rather than hardware issue.

Yes, BUT... I've found MM ROMs on other devices where this doesn't happen...
Be careful that on Nougat this option is no more available...

OpenVPN not working properly

Hello!
I have Poco X3 NFC with built-in MIUI 12 (Android 10) with latest secpatch.
I didn't unlock the bootloader due to security concerns, so phone doesn't have root / custom recovery.
Problem is related to OpenVPN app, I got the settings file (*.ovpn) from my sys admin, and it was imported correctly, the app even tells me connection was established with no errors, however in fact no traffic goes through the VPN, everything goes through default connection - IP not changed, no access to intranet and internal web resources. On my PC everything works OK.
May it be related to the MIUI specifics? Or is there some Android bug?
Please, tell me if you faced same issue, and it would be very-very cool if someone here knows the solution for this problem.

Question HW MAC changed after upgrading to Android 11

Finally my Xiaoxin Pad Pro got an upgrade to Android 11. It took a while, everything seems fine, apart from one strange thing: The "hardware"/wifi MAC address was somehow changed during the process. I discovered this after the tab wouldn't connect to my wifi anymore (I utilize MAC whitelist there).
If I go to Settings / System / About tablet ... the "WLAN MAC address" listed there is OK, as before.
If I go to Settings / Network & Internet / WLAN ... the "Device MAC address" listed there (for the two saved wifi connections) is something completely different (i.e. totally different range as well).
I tried rebooting, shutting down, turning "private MAC" on and off again... the "new" MAC remains the same.
Querying the MAC's online -- the actual ("old") wifi belongs to
Motorola (Wuhan) Mobility Technologies Communication Co., Ltd.
No.19, Gaoxin 4th Road, Wuhan East Lake High-tech Zone, Wuhan

Has anyone else also encountered this after the upgrade (on either Xiaoxin Pad Pro or P11 Pro version)?

I've looked around and found a few other cases (Nokia and OnePlus):

Device MAC address changed after android 10 stable update
After upgrading to OxygenOS 10.3.0 stable update I have noticed that the "device MAC" address has changed compared to what it was originally from the factory. I have verified this with the MAC address on the box the phone came in. I get this...
forum.xda-developers.com
But nothing conclusive as to how & why it happened in the first place, and how to fix it. At least the MAC is "stable" and all I had to do was replace it on the router's whitelist.

Exactly same issue here. The MAC address on my Lenovo P11 changed after upgrade to Android 11.
The new MAC is stable and does not seem to cause any other issues.
I did however have the known problem of screen turning itself on randomly whilst in sleep mode.
This is the worst tablet I have had! Full of bloatware and no third party OS for it.

Question Random mac address despite disable

Cross posting from the 9 Pro forum in case anyone here has the same issue or might have a solution, as both the 9 and 9 Pro suffer from this bug.
Random mac address on every reboot
Hello, I have a problem with mac address on Oneplus 9 pro LE15BA OOS 11.2.10.10. Every time i reboot device i see slightly different mac address in settings even though i disabled mac randomization in wifi settings. Has anyone run into the same...
forum.xda-developers.com
The issue is your device gets a new MAC address every time you reboot despite me turning OFF this "feature", which is a huge issue for people like me who deal with MAC filtration on networks for security. My 10 Pro does not have this issue
