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

2019-09-08, 2:49 AM

What helped me was to make sure my tab connects to 2.4ghz wifi only.

 

Most routers these days have twin band setup

 

5 GHZ - high speed and low range

2.4ghz - lesser speed - distant range

 

On my router config, i blocked the mac of my tablet for the 5Ghz.

 

This made sure my tab connects only to 2.4ghz


So far no issues.

Currently running Android 7.1.1  -> TB-X704V_S000038_171219_ROW

 

So far no issues since last couple of days.

 

The reason i did this was that the Wifi issue was always faced when i connect my tab to my router, with frequent wifi drop state midway through browsing.

 

But when i connect to my iphone hotspot there was no issue. I noticed the wifi hotspot was always 2.4Ghz. Hence made this setting.

 

Life has been good so far.

Hi same problem here. 2-4G is OK, 5G is no go on Lenova M10 tablet. I have tried many of the router configs mentioned above. I did have momentary success by changing wifi security on 5G band to WPA/WPA2-PSK as per this thread: 

 

https://forums.lenovo.com/t5/Lenovo-Android-based-Tablets-and/M10-Tab-won-t-connect-to-wifi-bluetooth

 

5G worked once, and then (after going out of range) the tablet would once again not connect to 5G. 

 

The problem in my case is that all my smart home objects run on the 2.4G band, so the tablet is competing with 20+ other devices for bandwidth and therefore it drops wifi connection on 2.4G band. 

 

If I could connect to 5G band, my problems would be fixed, but alas, it seems like I'm stuck with a piece of junk. 

 

Hopefully someone who is thinking about buying one of these devices has read this forum and saved themselves some grief. STAY AWAY from lenovo junk tablets.

Strange !

 

At home I have only 2.4ghz and my TAB 10 Plus works fine and at my brothers place who has both 2.4GHz and 5 GHz it runs fine on 5 GHz !

 

My Home 2.4GHZ Router settings:

Channel: 1

Mode: 11bgn mixed

Channnel Width: 20MHz

Max Tx Rate: 130Mps

WPA/WPA2 - Personal

2.4GHz has not been a problem for most; just 5GHz. In my experimentation, I could connect to 5GHz with very good performance, but only for a limited period of time. At some point the connection would appear to be up, but no data would flow. Turning wi-fi off and back on again would fix it, but only temporarily. With 2.4GHz, I have no such issues.

I'll link my answer from another thread

https://forums.lenovo.com/t5/Lenovo-Android-based-Tablets-and/Lenovo-tab-4-10-plus-5GHz-bug/m-p/4300521/highlight/true#M40782

 

Try changing to a lower frequency/channel within 5Ghz band

I'm having the same problem with my model TB-8704V Android version 7.1.1 Security patch Nov 1, 2018.  When I have it on WiFi 2 or 5 for 5-10 minutes apps start quitting and then it quits.  Tried repeated reboots, safe mode, still the same problem.  Did a factory reset - it worked for 1/2 day, then same problems.  Says I have all current updates.  McAfee says Wifi secure, no viruses.  Turned wifi off and read a book for hours, no problem.  When I turned wifi back on, apps started quitting, then it shut down.  HELP!

Here is what worked for me: 1. Go into Internet Settings {Android 9} and change Private DNS from Automatic to Off. 2. Connect the P10 directly to a wifi repeater using the password of the router. Advise if this fix does or does not work for you.

Lenovo does not support Android 9!

 

You can use Android 9 or 10

Both are working good.
