LENOVO TAB 2 A7-10F + TP-LINK Archer C25 impossible wifi - Miscellaneous Android Development

Hi,
I have some wifi issues with my tablet, it does not like new Archer C25 but it still works just fine with the old TL-WR841N.
The issue looks like this:
- connecting to my wifi - no problems
- download an app from play store - no problems
- try again - no internet - still connected to the wifi :crying:
- turn off wifi and turn it back ON - internet works for a couple of minutes and back to start
Nothing works to fix it what i tried already is:
- fresh bloody android flash, and downgrade
- factory resets
- changing router settings: security WPA/WPA2, TKIP, AES, channel, transmit power - nothing works
- tried some android apps called wifi fix - nothing works
New router has no problems in terms of stability with any other device: 1 PC via LAN, 1 laptop via wifi, 3 android phones 1 of which on 5Ghz bandwidth.
This is so stupid incompatibility i have absolutely no idea whats left to check. HELP

Connections help

Hi
I'm having some data connection issues and would like some assistance.
What I need is:
1. When at home - my phone connects to wifi router for all data (currently working)
2. When out and about - my phone connects via EDGE/3G/HSDPA for data connection (Currently working)
3. When at work - my phone connects to my pc to get internet connection over work LAN via the work proxy. (NOT WORKING)
Can anyone advise how I can set up a wi-fi network for option 3 - that enables options 1 and 2 to exist with minimal fuss or settings changes.
Please include config advise for both laptop and WM phone. I'm using a samsung i780 with WM 6.0.

[Q] Wifi does not communicate after 4.1.2 update

I've seen this across 2 devices now - the moment I update to 4.1.2, the wifi stops working.
- It sees networks fine
- It connects to networks fine
- It stays connected fine
- It does not transmit data over the networks.
The arrow icons flash as if it were doing something, but it's not actually displaying any results - apps do not update, browsers do not work, anything that needs the internet to function does not function.
Is anyone else seeing this? Android 4.04 works great, and I've not had any problems with it. It's good that 4.1.2 is an optional update.

Wifi not working properly

Hi, for a couple of weeks i'ts been impossible to use Wifi in my Z3. It's a loop, connect - couple of seconds - disconnect - scan.
Here's a video: https://www.dropbox.com/s/vl8221j836kliky/ScreenRecord_2016-05-04-18-58-54%5B1%5D.mp4?dl=0
I tried to solve the problem from the smartphone and from the router.
- Changing wifi channels
- Using another security and encryption
- Trying 2.4ghz and 5ghz
- Static IP
- Safe mode
- Disabling optimizations
- Changing rom
Any help? I really need to solve this.
I have the exact same issue on Xperia Z3 Dual Marshmallow. Have tried everything but it just disconnects and then reconnects again. Other phones are working fine with the same Wifi.
All networks or just this one?
It was with all networks. I repaired the phone software yesterday with Xperia Companion and so far it seems to be working fine now.

[Completed] Problem with Wifi Connection, no common issue

First of all thanks in advance for your support.
I have a rooted android Tablet Szenio 785qct with Android 4.2.2, it was working very well but the battery and the wifi had problems.
I thought that the wifi problem was in relation with the battery power, but after the replacement of the battery it persists.
The problem is very strange because:
- I switch on the wifi.
- It looks for the wifi connections.
- It Connects and an IP is assigned.
- But it does not navigate in internet.
- The info of the wifi connection says that is connected at 0 Mbps. The signal is full, i am near the Access point.
- DNS is assigned ok.
- File hosts is clear. (only localhost 127.0.0.1)
- I can connect with Ethernet wire or with bluetooth to my mobile phone shared connection and it can connect to internet. But not with wifi.
After this, I have searched for this problem in any way, but I did not find anything.
I dont know if it could be a bad configuration…
I would appreciate an idea for this…
Hi !
Sometimes this happens after a software update , try to reset the wifi router
Good luck !

Wifi disconnecting ...

Hello people, I have 45 pieces of Blackview GBV 5500 Plus and with each one I have a problem with connecting and reconnecting to wifi without internet. The devices are designed for a scoring system that should be free of the Internet. The wifi network is built of four APs in roming from ubiquiti. My problem is that the devices cannot automatically connect to wifi in romming when they do not detect the internet. Is it possible to fix this problem somehow, or can you advise me a functional wifi manager to replace the built-in wifi manager or another apk that would solve this problem?
Android 10
Tunr on Wifi automatically - ON
Save network - only one
