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.

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.

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.

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.

    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 😊
