Wifi losing connection

Hi all. I'm having an issue where my devices will lose wifi connection for a few minutes at a time. Its happening more frequently now. My hub will flash a green Wi-Fi light whilst I'm disconnected.

Once the light stops flashing my devices reconnect. Has anybody had any problems like this?

Re: Wifi losing connection

Connect to the hub by clicking on this link http://192.168.0.1/  That should pull up the log in page for the hub.  But don't log in, just click on the link "Check router status"  That'll bring up a window with five tabs.  Open the Downstream tab.  Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as TEXT not screenshots.  Post that, do the same for the Upstream and Network log.  You'll get an error message when you post the Network log, just click on "post" a second time.

Then we can check for any obvious problems with power, noise or error counts.

Re: Wifi losing connection

There's too many T3 timeouts on the upstream, and in my view the 4.7 dBmV range of downstream power values is probably too wide.  When was the hub last rebooted, as in you intentionally powered it off and then on again?

Re: Wifi losing connection

I couldn't say to be honest, not for a while though. I'll do that tomorrow and see if that helps. It's a strange issue really, I've had no problems at all today and probably won't for a few days, only seems to happen when everyone is home and all on there devices at the same time.

Thanks for the advice and I'll give that go.

Re: Wifi losing connection

Hi Stephen14,

 

Welcome to the Community Forums! Thank you for your first post.

 

I am sorry to hear you've been having issues with your WiFi and hub over the past couple of days - I've been able to locate your account and everything looks to be completely normal on this end and no identified issues with your primary connection. However we can see that there is a WiFi coverage issue.

 

How have things been since Sunday? Can you please try factory resetting your hub to see if this helps at all? To do this, you'll just need to stick a pin into the pinhole at the back of the hub for at least 60 seconds.

 

Let us know

 

Beth
