Sure Signal - Call Audio Quality Issues

[Retired-George]

This issue has the following symptoms:

• Poor audio quality on both outbound and inbound calls
• Particularly affects customers using a Virgin Media cable connection

If you’re only experiencing poor audio quality one-way (for example, the call sounds fine to you, but the person you are calling reports poor quality), then this is most likely due to insufficient bandwidth on your broadband connection and is not an issue with your Sure Signal.

Troubleshooting:

If the person you are calling can’t hear you, this is usually caused by low upload speeds.

If you can't hear the person you've called, this is due to low download speeds.

Check if your broadband connection meets the minimum requirements.

Please run the broadband speed checker.

If your connection fails any part of the test, this indicates an issue with your Internet Service Provider and you’ll need to contact them to discuss this further.

Your connection speed will vary throughout the day, so we recommend running it at various times to get an accurate reading.

Check for planned maintenance.
Planned maintenance can cause periods of downtime, so check the forum for any planned maintenance. If there is, this will be announced at the top of the Sure Signal forum.

Reset your Sure Signal:

Sure Signal version 1

• Connect device to internet and power supply

• Press and hold down the reset button (located near the internet port) until end of the process which will be indicated

• Remove the power cable at back of the unit and wait for five seconds

• Reconnect the power cable back to device

• Wait for the LED sequence to flash from top to bottom and back to top

• Wait for five seconds

• Release the reset button

• Within 10 minutes, all the 4 LEDs will start to flash in sequence – 1^st & 3^rd then 2^nd & 4^th then 1^st & 3^rd – with the sequence repeated. This sequence indicates the start of the factory reset procedure.

Sure Signal version 2

• • Connect device to internet and power supply
  • Press and hold down reset button – located near the internet port
  • Wait for all the LED (power + 2 white LED) to light up for few seconds (power LED will always remain lit)
  • Wait for five seconds
  • Release the reset button
    
    
  • Within 10 minutes, 2 white LEDs will start flashing continuously – power LED will always remain constant in addition (unless there is an issue with local connectivity)

Sure Signal version 3

• • Connect device to internet and power supply
  • Press and hold down reset button – located near the internet port
  • Wait for 20 seconds
  • Release the reset button
    
    
  • All the LEDs will temporarily switch off for about 10 seconds. The power LED will then light up and remain constant whilst white internet LED flashes continuously.

The Sure Signal will be back online in around 1 hour.

Move Your Sure Signal Away from the Router
Sometimes the Wi-Fi signal from the router can interfere with the 3G signal from the Sure Signal and this could result in poor audio quality.

In order to prevent this from happening, please ensure that your Sure Signal is moved away from the router as far as the cable will allow.

If you’re still experiencing poor audio quality, post in this thread and we can look into it further.

Hi jenny

The serial number is 21221765619
I have rebooted it and I have the top two lights on and the bottom one too.

Hi DaveBisgrove,

Your Sure Signal updated on the network at 6.13pm yesterday.

Is it working ok now?

Thanks,

Gemma

[DaveBisgrove]

Hi Gemma. No still no joy.
I only have a couple bars on phone signal. I used to have full signal always

Hi DaveBisgrove,

Have you had a recent SIM card or phone change recently?

Thanks,

Hi there,

No it's the same iPhone and sim I've had for a few years . I have also got a new iphone6+ and it's also not connecting.

Hi DaveBisgrove,

Everything looks fine from this end and the lights on your Sure Signal confirm that everything should be fine at that end too.

It’s a little puzzling.

I would suggest removed and re-adding the numbers attached to the Sure Signal (this may mean you need to deregister and re-register).

Thanks,

Wayne

[DaveBisgrove]

Hi Wayne. Ok I have re-register the sure signal but still a very week signal. I had a text to say it had registered.
Not sure what else to do. It's very worrying as I have just entered into a 24 month contract paying £65 a month. If I can't get reception I'm my apartment I'm screwed 😞 what else can you suggest?

[Retired-Simon]

Hi DaveBisgrove,

You’ll need to wait at least 24 hours before re-registering the Sure Signal.

Please can you de-register, wait 24 hours and then re-register.

Re-registering immediately won’t have any effect.

Thanks,

Simon

[DaveBisgrove]

Hi there.
I tried leaving it and then re registered it.

Still no joy

[Retired-Simon]

Hi @DaveBisgrove,

To rule in or out a faulty Sure Signal, please can you try it on an alternative connection?

If it still doesn’t work, it’ll need replacing. If you get signal okay, there’ll be a further underlying issue with either your line or your router.

Thanks,

Simon
