No Ranging Response received - T3 time-ou

Hi all,

Having real issues with our WiFi dropping intermittently.

I have rebooted and reset my Hub 3, but still keep getting the following errors:

T13 - VM.JPG

Assume this is fairly serious and may need an engineer?

Thanks!

Re: No Ranging Response received - T3 time-ou

Good Afternoon cb_18

 

Thanks for your post and I'm sorry to see you've been having issues with our broadband services. 

 

Has this issue since been resolved or is this still on going? I've taken a look at the stats of the hub and everything currently appears to be in spec. 

 

It does appear you may have a Wi-Fi issue, do you have issues with any particular devices whilst connected to the services? Do you notice this effects you in any particular rooms in the property?

 

Kindest regards,

 

David_Bn

Re: No Ranging Response received - T3 time-ou

Hi David_Bn,

Apologies for the delayed reply.

The issue still occurs, even though out network has been split into 2G and 5G variants.

The router seemed to have a real issues yesterday - the network log page is full of critical statuses relating to T3 timeouts.

As for devices/locations it can be any device (phones/tablets/laptops) no matter where they are in the house.

Any suggestions?

Thanks

Re: No Ranging Response received - T3 time-ou

Do wired connections also drop?

Re: No Ranging Response received - T3 time-ou

Thanks for the post Cb_18.

 

Can we please confirm if you're still experiencing some speed issues through WiFi? 

 

If this is just through WiFi we have our WiFi tips here. 

 

This would include making sure your Hub is out in the open, upright and at least 1 metre away from other electrical devices if possible to stop any interference with the signal. We would also advise to forget the network on the devices having trouble and reconnecting this making sure it's in the area the device will be used from, we can advise that devices closer to the Hub should be on 5Ghz connection and further away the devices should be on 2.4Ghz.

 

Thanks, Emily.
