This issue presents the following symptoms:
For version 1 Sure Signal (the one with four lights on the front):
- Lights one and two are solid which indicates the Sure Signal is connected, but isn't giving a 3G signal.
- Light four doesn’t light up or lights occasionally and then goes out at certain times of day.
For version 2 Sure Signal (the one with 3 lights on the front):
- The power and system lights are both solid, indicating that the Sure Signal is giving a 3G signal.
- Your registered phones don’t pick up a 3G signal.
For version 3 Sure Signal (the plug in version):
- Power, internet and service lights are solid and the ‘in use’ light is either solid or flashing
- Your registered phones don’t pick up a 3G signal
Troubleshooting steps:
Check that your broadband connection meets our 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 (ISP) and you’ll need to contact them to discuss this.
Your connection speed will vary throughout the day, so we recommend running it at various times to get an accurate reading.
To ensure the Sure Signal broadcasts at the correct frequency, it sends and receives small amounts of data to a Network Time Protocol Server hosted by ourselves. If these packets of data take longer than 240ms to make a round-trip, the accuracy can no longer be ensured and so the Sure Signal will automatically stop broadcasting and light four will go out.
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:
- Hold in the reset button until all lights go solid
- Pull the power lead out with the reset button still pushed in
- Continue to hold down the reset button and reconnect the power lead
- Wait for all lights to come on and then release the reset button
The Sure Signal will be back online in around 1 hour.
Configure your Router Firewall.
The IP address and ports used for NTP (Network Time Protocol) synchronisation are listed below. You may need these to configure the correct firewall settings on your router.
This step isn’t usually necessary, but it may help if you’re using a complex network (such as a corporate or office LAN), or a complex router.
We recommend contacting your ISP or router manufacturer directly for detailed instructions on exactly how to change your router settings. Alternatively, select your router make and model over at http://portforward.com and follow the default guide there.
Destination IP addresses:
- 212.183.133.181
- 212.183.133.182
- 212.183.131.128/26
- Protocol = UDP
- Port = 123
Please note that in the list of IP addresses above, the notation "212.183.131.128/26"means the entire range of IP addresses between 212.183.131.128 and 212.183.131.191
Perform a PathPing to our server.
In order to check if the Sure Signal's able to communicate with our NTP server, a PathPing can be performed as a test. In order to do this, you'll need to open the command prompt in Windows as follows:
- For XP just click Start > Run and type cmd then hit enter
- For Vista/Windows 7, press Start and type 'cmd' into the search bar
- Right click the result and click ‘Run As Administrator’
Once you're in the command prompt, type in PathPing 212.183.133.181. This will perform a trace route to the NTP server and will show you the route it took to get there. One of the columns will display packet loss, if this occurs before hitting our server, you'll need to contact your ISP for further assistance.
If you've completed all the troubleshooting steps above and not identified the cause of the issue, your Sure Signal may be faulty. Please post in this thread and we can look into it further.
Thanks,

I have my pathping results and have no idea what it means. Would some explanation be an idea on the reading of them? NB I am not a geek.
Would it help to eject the box thru the window? I cannot face another call to Mumbai.
Hi 18monthstogo,
Thanks for letting us know that you're too having problems. If you'd like to upload a copy of your pathping results, I'll be delighted to have a look to see what's going on.
Cheers all,

... Hi there Hammarton,
I can totally understand your frustration here, but if you're getting 100% packet loss then this indicates a problem with your ISP and I'd be inclined to advise you to contact them...

Hi Lee,
Your statement above isn't necessarily entirely true ...
If when Hammarton says "Tried the ping to 212.183.133.181 and got 100% packet loss" he really means what he says and he tried ping rather than pathping, then the observed result is entirely predictable since your Vodafone servers don't respond to ICMP pings. 'Request timed out' / '100% loss' is the expected result and doesn't indicate any fault of the ISP or in the router settings.
Hammarton,
To get a useful result you would need to run the command pathping 212.183.133.181, in administrator mode on Vista or later, and then wait to allow it to return a full set of results. This will then show the round trip times and packet loss at each step through your ISP's network as far as the Vodafone gateway (VODAFONE-LTD.TenGigabitEthernet7-1.ar6.LON3.gblx.net ) - you still won't reach the SS server.
