Edit: This is the Galaxy Tab 7 Plus 4G w/ TMobile...
So far I am loving it. I have had a plethora of Android tablets, including the Galaxy Tab 10.1 (until yesterday), and the original 7" Tab. Here is an issue I have not run into thus far...
Issue 1: I like my brightness settings to be %100 all the time. I always (almost) have a power cable with me, so I'm not worried about the drain. I have the auto setting turned off as to keep it from adjusting on it's own. However, everytime I open the status menu with the brightness slider, it is down to about %90-%95. I can't get it to stay on full. Also, and even more annoying, every time I open the browser, the brightness drops to like %30'ish and I have to open the status menu and slide it back up. The browser is where I REALLY need the full brightness the most, and it's the biggest issue.
I noticed this out of the box, adjusted settings, nogo, so I factory reset, and same issue. This is leading me to believe this is just a setting or something I am missing. Any ideas?
Issue 2 (THE BIG ONE): This Tab 7+ can't see my work wifi. It connects to my wifi at home just fine (did last night at least), which is also WPA, but it doesn't even see the one at work. It acts like it isn't there. In fact, and this is probably important, it is not seeing any networks up here, and there are at least 10-15 that should be visible from my location in the building (all but a couple from other companies). My G2x (Android 2.3) is connected to my work wifi just fine, and it sees all the others around us, the the Tab 7+ right next to it sees none. I also turned on the wifi router on my phone, it will not see that one either. I've verified the wireless is enabled, as well as turning it off and on multiple times and many reboots, nogo... I need it to hit the wifi at work and home so it isn't sucking my 4G data, so this is a big issue for me.Any ideas? I'm at a loss...
Also, to answer before it's asked: Nope, it's not rooted. I may do this at some point (as I do most of my devices), but for the moment I want to leave it stock and not mess with it. These issues seem like they should be resolved/nonexistant in the stock ROM, so I shouldn't have to root to fix them. Please tell me if this is incorrect...
Thanks for any help, sorry for the long post...
(pardon typos, I'm at work and multitasking, no time to proofread)
on the brightness broweer tip. use a different browser. its a known issue that the stock browser automaticaly dims the screen.

Thank you... You're right, it doesn't happen in Dolphin, however I am one of those weird people the really prefers the stock browser...
The biggest issue is the wifi not showing up. I am updating that issue with more info now...
what channel is the wireless network on? i had a similar problem on my windows laptop, it cannot see the wifi.. turned out that my wireless card(the driver actually) cannot see any wireless network beyond channel 12.. who knows you're having the same problem, might worth checking.

Ours is on 6... Thanks though
for me it was the opposite, it could see my home wifi, but not my work.
only was to solve it was to setup a static ip at work for the GT7...
I called samsung, they said its a problem with some routers. No eta on fix other than static IP.

Just to chime in - I also have the same problem connecting to my work wireless network but I think because it uses a SEPARATE authentication scheme.
The way my office WLAN work is like this:
1). Connect to the WLAN with SSID "Office", no encryption password required
2). Once the Tab is connected, it WILL receive an IP address
3). Open up a browser (Dolphin, etc.) and try to go to any website (Google, etc.)
4). Instead of going to the website I typed in in no. 3, an authentication page will show up
5). I need to enter my Windows AD account and password
6). If its successful, then I can start browsing the Internet (but not going to the Internal network, that requires VPN access).
Step 3 is where the Tab FAILED to do so. It just doesn't want to get redirected to the authentication page.

Yep, same way for me at work. OP did you try to manually add the wireless info vs letting the tab "find" the access point?

One of the ones we have at work is the same, but not the one I primarily use. That is my backup lol...

I did, nogo...
Also, here is a strange thing. About 2 hours ago it notified me there were wireless networks in range, and then showed me 2 random networks from another office. Suddenly, it saw nothing again. Then about 5 minutes ago, while I was in the bathroom ( ), it suddenly showed me ALL of the surrounding networks. Yay! I tried to connect to the one I use, it took my password, but never even attempted to connect. Then, they are gone. Now it doesn't see them.
What. The. Fuuuudge.
I have a Galaxy SIII mini which has been hacked 4 times in the last 8 months that I have had it. Usually, the first 3 times, were kids doing pranks, turning on my bluetooth,etc but this last hack was malicious. Started turning on my GPS, bluetooth, and camera flash light then progressed to changing my system language and finally making it so that my sim couldn't connect to any cell towers. I have tried app locks, but this last time inspite of two seperate app locks, he succeed with ease to change my settings. I also subscribed to a VPN with a NAT firewall and that didn't help at all either. Now I have redid the OS again, this time installing CM 11 and I welcome any suggestions on how I can stop this from happening all of the time. Thank you.

what kind of hack are you talking about? is someone using your phone, or remotely accesing it?
remotely accessing it. no one has physical access to my phone.
You should set a encryption password for your phone and use the app : Lockdown pro to restrict access to everyone who don't know the password.
Stay tuned for my first CM11 theme soon.
What do you mean by encryption password? You mean to encrypt my phone?
I did install that app. One thing that I really like about it is it's ability to stop the installation of apps which is what I think that the hacker is doing: installing some sort of app on my phone.
Settings > Security Settings - Encrypt phone > see instructions there .
@Gaon101
Stay tuned for my first CM11 theme soon.
After doing more reading online, I believe that the hacker(s) may have their own 'cell network' and may be exploiting my phone whenever it connects to it. How can I prevent this from happening if that is the case?
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.
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.
I just want simple DNS ad blocking without having to install an app on my Android phone. I tried the free DNS from ControlD and I noticed when using my phone several times a day I get a notification that Internet isn't available because "Private DNS cannote be accessed." I figured it may be unreliability at ControlD so swithced the DNS over to AdGuard's. Get the same error three or four times a day. When it happens, phone switches to cell data for about 30 seconds then goes back to wifi and all is fine.
I'm using their DNS just on my phone, not on my home wifi router. Although that my be kind of cool to do as any guest connecting to my wifi wouldn't have ads. But I prefer to leave the router using the ISP's DNS.
We and many others are in the same boat. I had this on different phones, with android 12 and 13.
Tried everything. Probably the problem is my Asus router+aimesh configuration with wifi 6. I tried everything in the router but nothing has fixed the problem.
Hard to understand if the problem is the router chip or a bug not fixed in last android versions or a bug in many dns providers.
Web is FULL of this PrivateDNS bug/problem but no one solution atm.

I've not had problems using dns.adguard.com for the past month. I did discover you need to turn private DNS off when using wifi on an airplane.

Yes, with that free public adguard dns i have no issue. Someone with samsung phone for example instead had it and fixed it with the public adguard family dns.
With personal adguard payed dns i have still always that "connection problem". Same problem also with NextDNS. Tried everything but nothing managed to solve this problem.
Same connection problem with ControlD. So weird...
It's really hard to understand what is THE really problem.
