We’ve created this thread to help with an issue that some people find during setup.
This issue has the following symptoms:
- The power light either constantly flashes or remains steady
- No other lights flash or light up
Please note that whether the power light is flashing or remains steady, this still points to the same issue - the Sure Signal hasn't established a connection to the internet.
The only difference is that if the light’s steady, then the Sure Signal has previously downloaded a profile from the server, if it's flashing then it hasn't.
Troubleshooting steps:
Check the physical connection between your Sure Signal and the router/modem.
In order to work, the Sure Signal needs to be connected to a spare Ethernet port on your router or modem, or a Hub/Switch that is connected to an internet gateway.
In some cases, it’s possible for an Ethernet cable to be faulty, in which case it may not allow your router and Sure Signal to talk to each other.
To verify that the Ethernet cable works, check the lights at the back of your Sure Signal where the cable is plugged in.
There should be a link light on permanently which indicates that an electrical circuit has been established through the cable.
There should also be a light which flashes whenever data is being passed through the cable. If either the data light or the link light do not come on, this could indicate a problem with the cable itself. Please try a spare cable, or plug the cable into a different port on your router/modem.
Check that you’ve got an active internet connection.
Make sure you can connect to the internet on another device, such as your PC or phone. If you can’t connect, this indicates a problem with your router or your Internet Service Provider (ISP).
We recommend rebooting the router to see if this then allows you to connect to the internet.
Reboot your router/modem:
- Turn off your router or modem at the wall for 10 seconds and then turn it back on
- Wait for the lights on your modem/router to indicate that an internet connection has been established
- Press the reset button on the Sure Signal
Check that your Sure Signal has been assigned an internal IP address by your router.
The Sure Signal must be assigned an internal IP address by your router. If your router supports DHCP (Dynamic Host Configuration Protocol), this must be enabled, as doing so will enable the router to assign an IP address to your Sure Signal automatically.
For more instructions on how to do this, please check your router manual, or contact your ISP or router manufacturer.
If your router or network configuration doesn’t allow DHCP, you’ll need to assign a static IP address to your Sure Signal's MAC Address by using your router's configuration panel. Please contact your ISP or router manufacturer for instructions on how to do this. The MAC address can be found on the sticker at the back of the Sure Signal.
BT Infinity customers.
If you’re a BT Infinity customer, you’ll need to log into your router admin page and select port clamping.
Once this has been selected please restart your router and Sure Signal.
Check your MTU settings.
Log into your router admin page and find the location of the MTU field. This varies depending on the make and model so you’ll need to look for it.
Change the value of the MTU size to 1500.
Log out of the router, this will usually result in a reboot.
Perform a reset of the 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 now try to contact the network and download its profile. This can take up to 6 hours.
Post your router/ISP details and Sure Signal serial number.
If you’ve done all of the above, or you’re struggling with configuring your router, please post your router's make and model number below. Please also include your Sure Signal serial number and the name of your ISP.
We find that other users of the same router will usually be able to share tips with you, to get things working.
We’ll also attempt to help with this, but due to the number of different manufacturers and models, it is not always possible. We don’t officially support any form of router configuration, so we’ll always recommend contacting your router manufacturer or ISP for assistance first.
Thanks,
Jenny
Hi Rahal,
I don't think I suggested that at all.
Every network will have coverage blackspots. It's just unfortunate that your area is one of these places.
I'm pretty sure there will be examples around the country where Vodafone provides a signal and our competitors don't. The difference is we offer a solution called Sure Signal 
I've just performed a resync of your device. Please allow up to 24 hours for service to resume. If it doesn't after this time, then please try another factory reset.
Cheers,

Hi FRdriver,
I'm sorry, but the person I escalated this to is out of the business so I escalated to another contact that I've yet to hear back from.
I've just chased this up for you again.
Cheers,

Hi Shudman,
Who is your ISP? I've just noticed your IP on the eForum and it shows as registered to the Netherlands. Vodafone block external IP addresses like this, as it’s not from the UK. If you can confirm your ISP I will get this lifted.
Thanks

Hi CaptainSlow
I've just resynced your Sure Signal device, could you perform a factory reset on your device?
·
To factory reset the Sure Signal box:
- Hold down the reset button until all the lights show (about 30 seconds) keeping the reset button held down.
- Remove then re-insert the power lead.
- Once all lights display release the reset button. The Sure Signal will come online in around 1 hour.
Thanks
Hi Shudman
Thanks for that I will get on this. I don’t suppose you know the exact ranges as I would like to make sure I get them all for you 
Thanks
