Smart Hub Disconnection issue

I've been having a strange issue with disconnections on my Smart Hub.

 

I was chatting on IRC and I got the message "Disconnected from server because the Internet is not reachable".  I haven't noticed anything strange otherwise.  When I got this message I immediately tried to load a website and, sure enough, the site loaded.

 

I checked the event log and Smart Hub stats are they read:

I note that the Smart Hub didn't lose any uptime after the second disconnection, which is interesting.
 
Any help or advice is appreciated!

Re: Smart Hub Disconnection issue

have you turned off smart setup?  did you split the 2.4/5ghz bands as some devices don't like them combined

 

try quiet line test  dial 17070 option 2  should be quiet and best with corded phone

 

are you currently using test socket to see if any improvement

Re: Smart Hub Disconnection issue

Hi imjolly

 

I just turned off smart setup.  

  

I dont have a corded phone, will I still do the test anyway?

 

I'm not using the test socket - I have a double faceplate.

 

How do I split the bands?  Sorry I'm not very technically minded.  Just noticed it says below "wireless off" I'm using wi-fi so I'm assuming that's referring to something else......?

Re: Smart Hub Disconnection issue

just select the toggle separate bands to on and it will automatiaclly add a 5 to the 5ghz bans to show which is which  you then can sign into both separately or both if device capable

 

however you have wireless turned off so no point as you don't use any wireless devices

Re: Smart Hub Disconnection issue

This probably sounds stupid but what is considered a wireless device? I have my phone / iPod / Switch etc all connecting to the hub via wi-fi. I thought that this would have been considered wireless?

I thought the bands were split actually due to this info:

2.4 GHz wireless network name: ************
2.4 GHz wireless channel: Smart (Channel 11)
5 GHz wireless network name: ************
5 GHz wireless channel: Smart (Channel 36)

Re: Smart Hub Disconnection issue

switch the wireless on the separate the bands then conenct your wireless smartphone/iphone/ipad/laptop to either the 2.4 or 5ghz or both

 

it sounds like you are connecting to BTWIFI or BTWIFI-x neither of which is your home network  the SSID of the hub will be the same for both bands until you split them  once done then connect to your home network
