Strange N-router Wifi problem 4.4.2

Hi guys,
Looked for an answer on this forum, no luck....
Problem,
When connected to an Wifi N-router, my wifi works for an certan amount of time and than drops. Wifi says I have a full conncetion but all my apps say there is no internet. Manually set Wifi on and off works until the connection drops again.
The strange thing is that it is only on N-routers. When I put the mixed mode on, it works like a charm.
But the problem is, Wifi is so slow on mixed that it is no option for long term.
Also it looks like even some routers with mixed on, makes the wifi drop. On my ubee modem every mode drops the signal, on a older linksys modem mixed (b/g/n) works.
Solutions tried:
- Got a new phone, same problem
- Factory reset, same problem
- Disabling Wifi power saver or any battery saver, same problem
- Change Wifi direct name, no luck
- Try apps like wifi repair, or signal boost, no change
- Static Ip adress, did not work
- WPA, WPA2, WEP, no luck.
- disable sleep on my phone, no luck
- Reset the modem, even factory reset the modem, same problem
- Problem was still existing after Firmware update....
I think I tried almost everything. Do one of you have the solution?

The issue was driving me crazy since the update to KK 4.4.2. It was like disconnecting the Wifi but the Wifi was not disabled, just the Wifi icon turned grey instead of the green when you are actually connected. Well long story short, turn off your BLUETOOTH and it will not disconnect anymore from Wifi. It seems to be a 4.4.2 bug.
Yeah I know.. who would have thought that?
Anyways, this works for my Acer E700 for days now and I am pretty convinced it will keep on working. Before this I was losing the connection within half an hour (but when on the power adapter the Wifi wasnt dropped)

[Q] Digimate T-705QI wifi not in range

Hi,
I've tried a factory reset but the problem is still there. The tablet picks up wifi signal, connects, but then gives an 'out of range' message. I've tried more than one wifi so not the modem. I have another identical tablet that doesn't have this problem. Any ideas?

Sony Xperia Z2 Tablet (SGP521) Wifi and Bluetooth problem

Hi all,
About a month or so ago I started to experience issues with with the Wifi and Bluetooth on my tablet.
At this stage I'm unable to switch on the Wifi or the Bluetooth. I'm only able to to use the cellular connection. When you try and enable the wifi connection is shows that it's trying to scan for a network, but it actually never switches the Wifi on. At times it actually pauses for a few seconds after selecting the Wifi option. Then at times it just doesn't do anything when trying to activate the Wifi via the quick pull down menu.
From what I have read it appears to be a hardware problem, but then I also saw comments that it might just be a software issue.
I was rooted at one stage and in my desperation I did a OTA update to the latest 5.1.1 release to see if that will help, but it did not.
When I was rooted I did a factory reset via TWRP, but that also did not work.
My device isn't under warranty anymore so RMA isn't really an option.
However I would like to check with the community if there is anyone else who had this issue and managed to get it fixed.
Is it a hardware or software problem or even a bit of both?
Would one be able to possibly replace the WIFI and Bluetooth radio in the Z2?
I normally use the Z2 for media consumption whilst at home over the wifi connection and would like to see if it can be fixed without costing an arm and a leg.
Your help or suggestion will be appreciated.

Question Disconnect double Wi-fi

From yesterday I have problem with double Wifi. When I connect to the other wifi network after a few seconds it disconnects and so on and so forth. Reset Network did nothing. It is running on Miui 14 updated version.
What could be the problem, not too keen on restoring it to factory settings.
