Question HW MAC changed after upgrading to Android 11 - Lenovo P11

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.

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.

[Q] Wifi Connection

I know this issue has been addressed in about 9000 other threads, but I have yet to come across one with a solution that works. I have a D-Link DIR-615 wireless-n router hooked up in my room, <5 ft away from my tablet at all times. My G Tablet is currently running TnT Lite v3.1, but has also had issues while running VeganTab and stock UI.
I'm about 35 seconds from turning my $300 tablet into a $300 hockey puck.
Help?
I have no problems with my router even though its not N. Do you have G/N turned on??

You must be broadcasting your SSID and the tablet will only make connections in the 2.4Ghz band.
Also you should have some 'http://192.168.X.X' address you can put in a browser, and a login screen will show up. If its your first time here, login was user: admin password: password by default for my router (NetGear WGR614 v9), might be something different yet simple like that. Option to enable wireless will be in there. Hope this helps, was having a similar issue a while ago and thought id share.

I haven't had much experience in this sort of thing. Most of my expertise lies in video production.
So, where would I find that information?
Thought I should also mention that my Vibrant had absolutely no trouble connecting to the wifi.

New user, so I can't post the linked page, but google "d-link dir-615 admin password" and select the top link.
This page lists your router specs. It looks like you need to knock 192.168.0.1 into a web browsers address bar. Then, use the username = admin, and leave the password blank. This will get you into your routers control console. From here, poke around until you find something interesting.

Question Lenovo P11 Pro WIFI problem

Hi!
Have had the Pro version for a while. It connects to my home mesh network without a problem. Asus XT8 (WIFI6). Works great!
At my work they also use a WIFI6 mesh network, delivered by Cisco I think. But I cannot get the tablet to connect. It doesn't even try to authenticate. My Pixel 5 connects no problem, also countless other devices, Samsung's, Apple's, etc. But my P11 Pro doesn't even want to authenticate. I've tried to reset the tablet, but didn't fix anything. It connected once and that was the very first time it connected to the work network. I've tried to use QR code from a device that has connection, no avail.
I've tried talking to my administrator, but to no help. My device, not their problem... And yeah, it most defiantly seems to be my device that has a problem. I found out they use WPA3 key (or at least has the option enabled), could that be the problem? At home and other networks I can connect to I belive is only using WPA2 key.
Android 10 is compatible with WPA3.
Have you tried "Forgetting" the SSID and trying to connect again?
Does the administrator have MAC address blocking on the router?
Thank you for answering.
I've tried deleting the SSID information from the tablet, but it doesn't rectify the problem. Same result, says "connecting..." under the SSID and the nothing.
I'll ask if they can check if the MAC been blocked! But, in WIFI options the MAC "spoofing"/randomizer in Android is enabled for this network
Try your MAC hardware address rather than random if you can. You'll be presenting to the router with different MAC addresses every time you connect and if they do have MAC address blocking then you'll be blocked.
I'm grasping at straws to be honest
Did you bought the Chinese version with global rom? because I bought it, and i was having problems with the wifi, I found out it was only with the 5 ghz network, it only connected to the Chinese allowed bands. The only solution I found was with magisk changing the props where the wifi region is located, but then you loose widevine L1.

I've talked to admin, they told me there's no special MAC ban. It's also NOT WIFI6 as I thought earlier, but 5, and WPA2-PSK. Same as home I believe.

No, this one is bought from Lenovo's website (DigitalRiver), based in EU where I live (Norway). One of the reasons I bought it was widewine L1 support XD.

I see no reason why it should misbehave then - strange.
Well, even then you can check if the wifi region is correct, you can go to the recovery and select "view recovery logs" and check the following props "ro.product.countrycode" and "ro.boot.wificountrycode" if any of this says "CN" then is the region wrong and the culprit is the lenovo oficial ROW rom.
ro.product.countrycode=SE
ro.boot.wificountrycode=SE
I think this would be correct as SE would correspond to Sweden. Norway and Sweden are neighbouring countries and I see often that many manufacturers doesn't have Norway as an option, but Sweden is listed (and Denmark...)
Or should I contact customer support and ask if I should have recieved one that says NO in these entries?
Well looks ok, you can use an app like wifi analyzer to see what channel is your work network, and if your tablet see it, if your tablet cannot see it, maybe they are using a forbidden channel (for example here in Spain you cannot use the 14 channel on 2.4 ghz network, but i found that some routers use it anyway), in case that the tablet find the network it can be a rom related problem. I doubt is hardware related because you said the connection is fine on your house and you can connect one time at your work. Anyway is not a bad idea contacting Lenovo customer support with the connection parameters.
It can see the network just give. In android and in Wifi analyzer app. Doesn't use any forbidden channels afaik.
Yeah, I probably should contact Lenovo.
Thank you for your help
Update:
Was in contact with Lenovo Technical Support. They hadn't heard about this issue before (OFC). But they recommended I do a what he called "hard hard reset" using Lenovo Moto Smart Assistant as the reset I've done is what he called a soft reset, using the factory reset in Android (not recovery).
So I'll try that and see if that helps.
I also asked about the countrycode beeing Sweden, I was told it is that for all Scandianvian countries.
Hello.
I have the exact same issue as BFalck. With the wifi in my home I have no problem while with the wifi at work I can't connect in any way. The network is seen and saved but the connection fails. I must say, however, that my unit is the Chinese one with the European Rom of Lenovo. BFalck let me know if with the "hard hard reset" you can solve. Thank you

Sorry to say, the hard reset didn't solve my problem.
Do you know which router/access point you're having trouble with? My job use Cisco air-ap2802i-e-k9.

I'm sorry but I don't know this detail. It is very likely that a Cisco device is being used, however. My company provides many wifi networks and the tablet connects to all but not the one that reaches my office...
So I had one of the administrators on site a couple of days ago. We've tried to error check the wlan. In the logs of the AP's the Lenovo tablet doesn't seem to even register trying to connect to the network. That confirms my suspicion there's something wrong with the WiFi in the tablet. Some kind of incompatibility with some devices.
I'll be attaching a image of the label of the AP's we're using.
I have this issue too.
My Xiaoxin Pad Pro ( installed with the Lenovo Pad P11 Pro ROM ) will not connect to my wifi 6 (ax) enabled router on the 5 GHz frequency for use with wifi 5 (ac), only connetcs to 2.4 GHz.
Really annoying. And I cannot disable the wifi 6 function to test connecting to ac-only.
Some backwards compatibility problems, perhaps. Or region specific configurations.
No issues to connect to 5 GHz using my old Netgear r6300v2 (ac-enabled).
Anyone able to connect to a WiFi 6 network?
Yes, no problem connecting to my XT8 mesh at home running W6. Workplace only has W5.
I managed to get it to work by changing the pre-selected channel option from ISP.
I had to find a way to bypass the locked option in the webUi in the router. (Praise the internet)
My ISP had pre-selected a higher channel range (B-range with DFS) and my P11 did not work with that.
The only other option was "without DFS" and that is only available in the lower A-range (channel 36, 40, 44, 48)
Hope this can help someone!
I can confirm as per previous forum member that this tablet cannot work with 5ghz control channels out of the A-RANGE. It is easy if the router is at home to be changed. At least in ASUS router. Maybe caused by CN wifi profile.aside from that I thinks this tablet is just perfect.

Question Family link [TB-J617F]

Hi all,
I've been trying to get family link working as my daughter uses this tablet. When trying to add her account the setup gets stuck in an endless loop never competing. Having read various threads from other devices, I think it's probably something to do with play services not having certain permissions. I would consider unlocking, installing twrp, magisk etc if required to fix, but I don't want to loose widevine.
The long and short is I can't use her account on the device at all as she's part of the family group - her account won't work at all without family link.
I wondered if anyone here had either tried this, or come across other odd behaviours relating to play services?
I'm running the Chinese ROM ziu 13.
Appreciate any thoughts.
Cheers Matt
Few things I have tried (and eventually got it to work) across 2x Lenovo P11 Plus (J616F)'s:
1st one was a factory reset and then instead of using my home WiFi, setup the device using a 4G hotspot from my phone. (Not a clue why, but my Home Wifi (Unifi Access Points) takes upwards of 2 minutes to get internet with the Lenovo's, even though all other devices are fine).
Second method:
factory reset and setup the device as "Offline" (i.e. dont input any WiFi details, button down bottom right saying "Setup as Offline")
Once gone through initial steps, connect to your WiFi, give it 10 minutes to update a few bits.
Open Play Store (DO NOT SIGN IN!), and press the three dots at the top right and goto updates
Let the device update all apps
When complete, try adding the childs Google Account (again, if this fails, try using a 4G hotspot from another device (disabling Wifi on that device first))
Hope that helps
Ok, that sounds pretty strange but I might give it a go. I just set her up a new Google account as nothing I could do could get the old one logged in. Thanks for your advice.
I suspect your unifi is running a shared ssid and your 5ghz is on an inaccessible band, are you always connecting at 2.4ghz? I had to change the 5g band on mine to even see it!

Only have my 5Ghz on normal bands (i.e. non DFS), even tried a separate 2.4Ghz Guest network, disabled WPA3, all to no avail. Not got a clue what caused it, my ISP doesn't block anything either (Zen UK)
Any other device was fine over WiFi (have setup much older Samsung tablets, newer kids phones) all with Family Link, it was just the Lenovo's that was stuck in a loop saying I needed to remove and re-add the account.
Just couldn't figure it out, and had already spent a few hours trying. Hoped the newest firmware would fix, but that didn't help either.
Hope it helps and good luck
Just playing around on the tablet and it appears that it struggles with IPv6 - could be that my hotspot is IPv4 only. Could be related to the loop it gets stuck in?
Not sure why it doesn't like IPv6 though as all other devices are fine with it...
I've just gone through full reset, then tried using 4g hotspot as you suggested. I have to use Lenovo app centre to get play store, then use play store with no login to update. That all works fine. Then add my daughters account. Then I get stuck in the same loop of not being able to register the device with family link.
In my case, I don't think this relates to internet access, I think there's something going wrong with the software / permissions on the device. It's genuinely very frustrating as I imagine it's probably not terribly difficult for the Lenovo Devs to fix.

Question Can't fixed the Mac address even “use the device adress”

Title: Random mac adress when using device's adress
Device: OnePlus 9
Software Version: LE2115_11_C.61
Probablility of occurance: 100%
Topic: Bug Report
Photos:
Carrier/Network:
Actual behavior:
Was this a problem in previous software versions: didn't happen in OOS11 but happend in OOS12 C36~C61
Expected behavior:
Any other comments:
From:
My OSS12 can't fixed the devices Mac addres when "use the device adress".
Every time I connect into the Wifi after reboot, the device MAC address changed even I have made setting "use the device adress" correctly.
I already tried to enable / disable the wifi non persistent mac randomization under the developer settings and keeps doing the same thing.
This started to happen just after the major android version update to OOS12, never happened in OOS11
Does anybody face to the same issue?
Yes, I do face the same issue after I rooted my phone/flashed firmware. I searched many times for the solution of this issue, but I never found a proper solution to fix it and I don't even know why this happens.

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
