Re: WiFi issue with Tab 4 8 Plus - Possible Solution

I have Google WiFi, and so far it only connects to 2.4 GHz with this method.

I'm right next to the unit too. Fingers crossed this holds. 

 

BTW... This does not seem to happen with the regular Tab 4 8, but then it doesnt do AC wireless. 


I can make mine die instantly on 5 Ghz by simply doing a test on the Speed Test app. It starts off a nice speed, then suddenly dies.

 

I tried 2.4 Ghz and it didn't die in the speed test, but then it only hit 50Mbps, I want to use the full 100Mbps of my connection. Really annoying because I love the tablet other than this, but dodgy wifi is a real deal breaker on a tablet.

 

Edit: Just forced by router to use channel 161 on 5Ghz and have managed to do a few 100Mbps speed tests without it dying! Hopefully it stays that way

How else have you connected your Tablet to your WiFi before?

Well it died again.... Connected to 5Ghz eventually. Don't think you can manually select channels on Google WiFi. If its any consolation, the latest iOS causes my iPad mini to drop wireless randomly, although not nearly as bad. Same fix, turn WiFi on & off.

I took my tab back to the store as Lenovo had NO attention in fixing this problem.(after sending so many emails and messages!) so glad i took it back! and replaced it with another brand. haven't looked back since.

 

BYE lenova! would NEVER buy another product from you again!!

Spoke to soon, mine just died again :(

Clearly an issue with the 5 Ghz wifi on this tablet, I have no issues whatsoever with numerous other 5 Ghz devices

I bought my plus on eBay for a very good price. Now I see why LOL.

Like I mentioned in an earlier post, this issue is not present on the Tab 4 8 that I bought from Micro Center. That doesn't do AC wireless though, and the resolution doesn't compare. The plus is way nicer, except for the WiFi issue .

 

Since I have Google WiFi... My solution for now was to re-deploy my Airport Express in Bridge Mode running hard wired off GWF, and created a separate 2.4 GHz only network.

 

That'll get me by, till a fix is in place. I really only wanted this tablet as a backup for Google WiFi configuration, as the iOS app is not as reliable. But it's hard to believe Lenovo hasn't found a fix for this with all the notes on the forum .

At this point, they obviously don't care.

Did some more testing. I was able to get 5Ghz to work so far, by not using AC Mode. I setup an Airport Express in 5g only mode. So far been solid for 10+ minutes. I've run about 10 Speed tests, and they've all worked too, where before on Google WiFi they crap out almost right away. Of course, N has lower max than AC wireless, but getting 90/90 speed tests right now when close to source. 

 

So seems the problem is not all 5Ghz signals, but the AC band .
