LG G Pad III 8.0 wifi 5G issues

[Wilberry]

Received the Nougat update last night and now my LG Gpad 3 will only connect to 2.4 wifi. It was working fine on my Rogers 5G router, but since the Nougat update will only connect to 2.4. Has anyone run into this? I have looked online and done a few things like reset network settings, removed my 5G and 2.4 connections and added them back to no avail.

Any help would be appreciated

@Wilberry - Thank you for joining the Fido Community and posting your concern. I appreciate you trying the different troubleshooting steps. What exactly happens when you try joining to your 5GHz network? Any error message?

I'm assuming you have other devices connected to the 5GHz network, just to rule out it's not the router issue. I suggest rebooting the router, usually, during the reboot routers scan the local environment and select the best channel available. 

Cheers!

I'll give that a try this evening, but do not think that will help as I have a Google Nexus Player which uses 5G, along with my Nexus 5 phone which uses 5G. Other phones in the home also use 5G, including an iPhone.

When I attempt to connect with the LG Gpad III to the 5G network it tries to connect and goes to saved (for the 5G connection). As mentioned 2.4 connects immediately and stays connected.

When I first updated the tablet it would connect and then drop after a minute or so, then less. I shut the tablet down, then started it again and it is now not even connecting via 5G simpy goes to 5G saved. As I mentioned I also reset network settings and removed the 2.4 and 5G profiles and then re-established wifi to no avail.

So I tried resetting the Rogers router and the LG connected for a minute and then went back to saved profile. I have logged a call with LG and will update as I get info. Surprised no one else has run into this issue.

@Wilberry Try removing the password for the 5GHz and see if it can connect and hold the connection if it does put back the password and try connecting again. Did you try clearing the cache partition on the tablet?

[Wilberry]

Thanks for the reply, I will give it a try tonite.

same issue with me. connect wifi 2.4 is good.. not 5hz. tried 2 different routers .. one dlink one asus.

honest.. didn't try remove password as this should not be a solutions... as it happened on different routers

After @Wilberry posted his problem I turned on my G PAD did the update and my 5GHz is connecting and working fine.

Interesting, I tried a few other things I found online and while the Gpad will connect occassionally, it never maintains the connection. The 2.4 works fine and will do as its not my main device, but is annoying.

BTW LG told me to do a hard reset of the tablet, but from everything I have read online it doesn''t do anything.

Also forgot to mention I did some ADB commands to get my SD card to be recognized as internal storage, but doubt that's the cause. I ejected the SD card and did a reboot to test and same issue, 5G craps out and it connects to 2.4.

Not that huge an issue, ran a speed test and get 36 Mpbs on 2.4 and about 50 Mpbs on my phone with 5G. Just irks me when things don't work as they should.
