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 there,
nope behaviour not changed I'm afraid 
still 1st light just flashing
On the router, I still see connections attempted to a variety of vodafone addresses all to UDP ports 4500 and 500. I've made sure that the IP address is fully open to and from the box in both directions.
I've reset it many times, tried different cables, a different switch etc.
Could the box be faulty?
Hi Guys,
Thanks for your posts here.
@ keithop, to be honest as the first light is flashing then it could be a faulty box that is causing the issue.
The definitive test of this would be to test it on a different internet connection and if you get the same issue then it is more than likely to be a faulty box.
If it still doesn’t work on a different connection, please follow the instructions on the PM that I have sent to you and one of the team will be able to follow up on this for you.
You can find your PM inbox here.
@ vwalker, I can’t see any emails in our email system from the address that you have used to register with the eForum.
So that we can get your issue checke3d please can you send us another email using the instructions in the PM and once done, please let us know so we can check the email system for you.

I had the flashing power light issue and the Sure Signal took out my internet connection then my Dlink DSL 2640_R rebooted. Could not get the Sure Signal on the network. It appears that my problems were two fold – firstly the ports the Sure Signal needed were blocked by my dlink router and secondly my router did not have the option to set up a static IP address to a network client (which is needed before port forwarding can be done). I pieced together 4 sets of information provided by helpful people – I paid Justanswer.com for the right firmware link to fix the static DHCP issue in my router, then copied two posts from TalkTalk forum members and added these to information emailed to me by Vodafone support. Here is what I had to do:
1 – download the updated firmware for my Dlink DSL2640-R router following the advice below
(Notes: the person who left this advise updated their firmware to resolve a "VPN connection reboots router" problem. I HAD TO TURN OFF MY MCAFEE FIREWALL TO GET THE FIRMWARE TO LOAD)
First things first, I have no idea if the following is TalkTalk approved and whether or not it will invalidate any warranty; execute at your own risk!
The OEM TT version with one I used to resolve my issues was a later version to the one used by the forum member (they used 1.06 to resolve the VPN issue), the one I used (vEU1.09) can be found here:
ftp://ftp.dlink.pl/d...river_software/
(If this link isn't working, simply search for 'DSL-2640R' in the support section of http://www.d-link.co.uk.)
Before you go any further, please make a note of your router configuration (especially your ADSL username and password). There is a backup option within the Maintenance Section – I strongly advise that you take a back-up of your current configurations
Unzip the new firmware to your desktop. In the ‘Firmware Update’ Section on your interface, select the .ras file and load this.
If you are trying to load a different version of the firmware, please note that for some reason the OEM TT firmware has a little piece of javascript validation that wants to see the filename end in ras. So make sure the file is renamed if it does not already have this extension - you should then find that the router will accept the new firmware, install it and reboot.
My router managed to keep all it's settings, with the exception of the wireless configuration, which I simply reconfigured. Now when I login to the router, I no longer get the grey TT opening page with the status lights and instead go straight to the ADSL setup page, with firmware version reporting:
2 – Set up a static IP Address for my Sure Signal (via it’s MAC address found on the router) following the advice below:
Log into the router configuration pages by typing 192.168.1.1 - User and password are both admin.
Click LAN Setup and scroll to Add Static DHCP (Optional).
•Select Enable
•IP Address: 192.168.1.2
•MAC Address: I typed in the Sure Signal’s MAC address here
Click Save
Static IP will be listed in the Static DHCP List
Click Save Settings
Repeat for any other Static IPs you want to assign.
Click OK to reboot
3) Set-up port forwarding to the Sure Signal static IP address, using the advice below:
This below is the link to a website called portforward.com but I have attached the exact link for your particular router
http://portforward.c...40R/default.htm
Plus here is the port information that you will need
Ports protocol
8 TCP
50 TCP
500 UDP
4500 UDP
123 UDP
This fixed all my issues -hope it helps
Hi guys,
Thank you all for posting. For anyone still experiencing the first light steady or flashing with no other lights lit, can you please let me know the following information:
-Sure Signal Serial Number
-Has it ever worked previously? If so, when?
-Is the light Flashing or Steady?
-What steps have been taken to try to get the Sure Signal working (reset, ports etc...)
The reason I'm asking for this information is so that we can pass some examples of this issue onto our supplier.
Kind Regards,
George
