My Lenovo tab 4 is unable to "see" the faster internet and some of the other internets that my phone / Kindle can see I was wondering whether this is an issue or not

Re: Lenovo Tab 4 8 Internet issues

Hello and welcome,

 

By "faster" do you mean the 5GHz band?

 

If your tablet is a Tab 4 8 (no plus) it is 2.4GHz only, and won't see 5GHz access points.

The Tab 4 8 Plus is dual band (2.4 and 5GHz)

Re: Lenovo Tab 4 8 Internet issues

Hi 

I've just purchased a TAB 4 8 and am having serious issues connecting to a UniFi AC Lite dual band Access Point. The AP wireless produces 2.4Ghz and 5Ghz signals concurrently. All my other devices (phones, tablets etc) automatically connect to the AP but no matter what I do the TAB 4 will not connect. I even have an ancient Nexus 10 tablet that connects effortlessly to the Unifi AP.

 

I have the latest update installed on both the AP and the TAB 4.  I have read the previous post which all makes sense (yes I realise that I've bought a 2.4Ghz only device - silly me) but why on earth can't a modern Tablet connect to a dual band AP. Makes no sense whatsoever. I have tried everything on both the TAB 4 and the AP to rectify the issue but without any luck whatosever. The only thing I have not done is do a factory reset on the tablet. Question: should I try that?

Re: Lenovo Tab 4 8 Internet issues

After the latest update, now i have problem connecting to 5GHz wifi which i could connect seamlessly before. I manually force the device to connect to 2.4GHz and it works normally. I guess here comes another firmware bug with the wifi connection. My advice is to wait for the next update....

Hi surveyor167

Can you please confirm that before the latest update you were managing to connect your TAB 4 8 to 5Ghz wifi? Are you sure you have the TAB4 8 OR do you have the TAB4 8 Plus?  If you don' have the Plus model and could connect to 5Ghz that flies in the face of

According to the official spec sheet the non Plus model isn't compatible with the 5 GHz band.

Re: Lenovo Tab 4 8 Internet issues

When I connected my action camera to my tablet I connected it through a wlan hotspot thing that it made and now I can not pick up my normal internet.

Re: Lenovo Tab 4 8 Internet issues

The 5 GHz is an issue since 2015, and hasn't changed since!

So the wait is 4 ever, I am afraid!

2.4GHz is not good enough!
