Smart Hub 2 Wi Fi devices are dropping connection and reconnecting

[acharris_77]

Hi all, I need some advice. I have the 900mb Fibre package and a Smart Hub 2. I am having issues where like my laptop is disconnecting from the Wi-Fi and reconnecting about 3 secs later. I have checked the log in the router and it shows that DHCP disconnected and reconnected a few seconds later. I see a lot of  2.4 G Client Deauthentications errors and today a lot of devices have disconnected on the Wi-Fi and they all seem to be on the 2.4 G band.

I remember back in May there was an issue with a firmware issue which was causing issues on the bands, but I got Firmware version: v0.27.06.04290-BT. It was cured until this firmware and then it popped back up. Gaming is a pain as the laptop or consoles keep dropping. On Ethernet it is fine and don't drop, but sadly not able to run the laptop hardwired permanently. 

Anyone having this issue?? I was looking to change to a 3rd party router, but I have the VOIP voice now so need the Smart Hub, but was looking to disable Wi-Fi on the smart hub and connect the new router to it and use it as the access point and keep the Smart Hub 2 for the Connection and VOIP. Would this work as the issue is getting annoying now. I have reset the hub and this works for a few days and then it develops the same issue.

Thanks in advance for any help and advice.

Hi and thanks for your reply. Yes I turned that off the 1st day I got the smart hub. Thanks again

Have you tried changing the channels from auto to fixed channels probably after using a WiFi analyser on mobile to find best channel for your home. Have you also tried changing wireless mode from 1 to either 2 or 3 to see if that helps

[acharris_77]

Thanks for the reply. I tried that and still the same. I only get a choice of 4 channels if I change from smart to normal and none are what the Wi-Fi analyser suggest. The SH2 only has limited choices by the looks. Thanks again.

Did you ever get to the solution?

I am having similar issues. More regularly now the laptop logs of and re-connects to the wifi... a second or two later.  I notice that am having to refresh browsers more regularly.  It never used to do this.

Hi, something I had as well. I think it resolved itself by me changing the channel. But to be honest, it was only 1 device that did it, my laptop. I changed to a wire for gaming but it could have been fixed by a firmware update. It still happens occasionally but cant do much as my phone line is now VOIP through smarthub

Thanks ACHarris.   As a test I have changed the 2.4Ghz channel as it appears it was that one that was dropping.  I am seeing re-logins onto the wifi again even as I write this.  Firmware v0.30.01.08093-BT

@pmosb 

Did you use a WiFi analyser to decide which channel to select?  Did you try changing the mode from 1 to either 2 or 3?

Make sure smart setup is turned off in hub manager

[pmosb]

OK - I have switched off Smart Setup (I assumed that was only a one-time use setup when installing a new hub.)

I use iStmbler to wifi analyse, and then the BT Smart Hub auto select and that channel on 2.4Ghz from 6 to 11 as that seemed less congested, although there are no direct conflicts on 1/6 or 11.

I am on Mode 1 and always understood that was the most stable vs speed option.  I am reluctant to fiddle with it . What are the benefits of Mode 2 /3 ?  The devices I am using are newish iPhones, Macs - none have previously had issues with the Smarthub so I am not convinced changing the Mode is wise - especially as it looks like 2.4GHz may be the band that is tripping out.
