Tab 4 8 Plus Wifi disconnecting.

2018-05-09, 17:11 PM

So I did not want my 1st post to be this bad! But I just received my brand new shiny Tab 4 8 Plus direct from Lenovo today 9/5/18. Had my eye on this for awhile. Looks great and specs are good. BUT having carried out all the upgrades since I switched on - which took ages as WiFi on Tab kept dropping out. I am next to my Router which is fast Fibre BT setup. I have IPad, Samsung phone, IPhone and no loss of WiFi on these. I have rebooted WiFi, rebooted Tab 4 and still when I go on line to use for instance - google or YouTube SUDDENLY I get spinning circles and then message - NO CONNECTION! I have never seen this on the other 3 tablets of phones. Extremely frustrating! This Tab is hours old and unless there is a fix etc or I can change something it will go back. So any fixes or try’s most welcome. Thanks

I had this issue also, the 000038 update combined with a factory reset solved this issue for me. Mine is the lte model 8704x.  Check in about tablet to see which software you updated to.

Thanks Wiznoodke for quick reply. So the Software Version is TB-8704F_RF01_170517. If this is what you mean? Is there a way back to previous sw versions? Android Version 7.1.1

The build number is what update you are on. You're F - wifi only. Your number will probably differ from mine. I'm X.  It's not easy going backwards. But you can. 

 

Before you get too far into data and apps installed, ect, try a factory reset.

 

You can also try the fix that was available for the x, which is sign into your admin page for your router and put your tablet onto 2.4 ghz. The issue (for the x, maybe your model too ) is the tablet is connected to 5 ghz. This is what creates the issue. 

 

ROW = rest of world software version

Brilliant read about the 2.4Ghz band so will give that a try through my router tomorrow. It does seem that helps but the bigger picture would be for Lenovo to fix it.

The update that had the Wifi defect was the one with patch level January. Since then another update has been released that seems to have fixed the issue judging from the posts in this forum (I'm using 2.4GHz only and didn't have it to begin with so I'm not having first hand experience).

HI HenryZ I have carried out all the updates that have been pushed to my brand new Lenovo. I still get the WiFi dropping out/no connection available- when clearly it still is. Can you please point me to the update fix?

Does it say January as the security patch level you're on? Can't hurt to double check. You can manually check for updates under settings - about device - system update, there is no other way to install than through this updating app.
