Re: Tab 4 10 plus wifi/internet problem - fix please!!

I have received a new firmware update last week on my Tab 4 10 plus 64gb Wifi tablet... I hoped that it would solve the wifi problems but it didn't solve anything for me. After update I still got problems on both 5ghz and 2.4ghz bands.. The 2.4ghz band a bit less often but it's still problematic. I have 4 different internet routers at home and I tryed them all out but every time I got this wifi problem with only this tablet. All other devices on my home network are fine.

 

I have done a hard-reset back to factory defaults with a complete data wipe and I even wiped the cache partition several times now .. it solved nothing.

 

I'm completely outraged with Lenovo for not giving us a solid solution.

 

Lenovo if you are reading this please contact me for a decent solution.

Same issue here. Got my Tab4 10 Plus yesterday and 5Ghz wifi has died 3 times. Only way to fix is turn wifi off and on.

So ... I picked up a Tab 4 10 Plus 4GB/64GB Wifi/LTE this week. I'm having the same 5GHz wi-fi problem as lots of other folks.

 

I spent some time on the phone with Lenovo support and finally extracted the suggestion to disable WMM (Wireless Multi Media) on my router. That did, in fact, resolve the issue ... the Tab 4 performed without a hiccup after that change. HOWEVER, turning off WMM dropped my wifi network speed from 170Mb/s downstream to roughly 25Mb/s across ALL of my devices ... phone, laptop, Smart TV, etc. THIS IS NOT ACCEPTABLE.

 

Lenovo has somehow broken the Tab 4's ability to use (or at least tolerate) WMM. TAKE OWNERSHIP AND GIVE US A FIX, LENOVO!

I'm somewhat embarrased to admit that, at least in my case, the issue may have been my router rather than my Tab 4. See this post for details.

Same here:

Brandnew Tab4 10 Plus 4GB RAM 64GB Storage LTE.
Wifi shuts down randomly.

No other device of mine and my family have this problem.

And I don't change anything at my router.

Why should I?

I bought this tablet for my holiday trip, starting in two weeks. Shall I change the router settings in every hotel on my roundtrip in the USA?

That would be funny...

 

SOLVE THIS PROBLEM LENOVO!

I'm now even more embarrassed to admit that it's the tablet after all.

If your problem is not solved, perhaps this might help. Go to settings, find lenovo launcher, empty cache and stop the app. I installed Nova launcher en after a few weeks the tablet still works fine. Before that I had the same issue each and every time, also after several back to the factory settings mode.

I've been running Nova Launcher since I bought the tablet, so I'm pretty sure that's not it.

 

After updating my router's firmware, I went for almost 3 weeks without an apparent disconnection issue, but the problem eventually returned. I'm confident it's the tablet's firmware/drivers.

 

While 5GHz would be nice, it's currently not an issue for me. All other non-wifi 2.4GHz usage (other than Bluetooth) has been eliminated from my home and I don't have any neighbors in range. So 2.4GHz works fine, and I have LTE when I'm outside of a 2.4Ghz Wifi coverage area.

I'm running Google WiFi mesh at home, so there is no ability to selectively turn off the 5 GHz band. Because the Google WiFi gives us really strong dual-band Wi-Fi across all rooms in our home, the Tab4 10 Plus usually connects to the 5 GHz band rather than the 2.4 GHz band - and whenever it does - no internet connection!!!
