Hello,
i detected by the linux-tool "iwconfig" that the mac-address of the hotspot is changing on every new hotspot activation. There is also a bug-report for it:
https://code.google.com/p/android/issues/detail?id=57452
In the comments is stated that doomlord fixed that problem. Is there any kernel in here for the nexus 5 from doomlord or others, which have this problem solved?
Very annoying with WICD forgetting the password and Windows always creates a new network.
Thanks for help.
Hi,
that's a serious problem for me too.
I would like to use the online services in my Mazda MZD Connect System.
Unforunately the system identifies an Hotspot by its MAC Address.
So whenever i switch the Hotspot off and on again a new entry is created in the car entertain system and i have to enter the password again.
This renders the function nearly unusable.
As i read yesterday, VW drivers have the same issue.
As there is only one line in the source randomizing the last three bytes of the WiFi Hotspot MAC, it would be enough to simply comment it out.
But building a complete new ROM on my own is far beyond my capabilitys yet.
Currently all Nexus phones are affected as well as CM 13.
ElementalX Kernel didn't help either.
HTC doesn't randomize the MAC nor does en iPhone.
But i won't change my phone just for a Car Entertain System.
Another option would be a little Mobile-WiFi standalone Hotspot with an additional SIM Card.
But this would mean extra costs each month which i would certainly like to avoid.
So here my questions:
Is there any Kernel to switch off MAC randomization?
Or any tweak to freeze one MAC?
Or a way i could start a script on switching the Hotspot on to override the MAC?
Or an completely different approach?
Any help is appreciated.
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.
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.
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

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.
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.
