Light one on, light two flashing

[Retired-George]

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’s on and light two flashes constantly
• Light two does not go solid

Troubleshooting steps:

Wait 24 hours.
It can sometimes take up to 24 hours for the Sure Signal to fully register with the server. Before attempting any of the steps below, please wait 24 hours.

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.

Check that your Sure Signal has registered successfully.
Before your Sure Signal can connect to our network, you need to register it with us.

You’ll receive a text or email to let you know when the registration is complete and your Sure Signal won’t work until you’ve received this message.

To check your Sure Signal is registered, login to your My Vodafone Account and click on the 'My Sure Signal' tab. Your Sure Signal details should be listed, along with the status 'Registered'.

If you’ve not yet registered your Sure Signal, you can do this directly from the My Sure Signal page in your My Vodafone Account .

If you’re a Business customer, please register on our business Sure Signal page.

Manually configure your router to allow port-forwarding.
In most cases, routers support a system called Universal Plug-n-Play (UPnP), which sets up port-forwarding for you automatically. If you’ve got a complicated network setup, or a complex router, you may need to enter these settings manually.

Please see the following for a list of IP addresses and port numbers that need to be forwarded to your Sure Signal's internal IP address. For instructions on how to do this, we recommend you contact your ISP or Router Manufacturer, or refer to the default guide for your particular make and model, over at http://portforward.com.

Destination IP Addresses:

• 212.183.133.177
• 212.183.133.178
• 212.183.133.179
• 212.183.133.181
• 212.183.133.182
• 212.183.131.128/26

Ports and Protocols:

• 8 – TCP/UDP                 (All routers)
• 50 – TCP/UDP               (All routers)
• 53 – TCP/UDP               (Virgin Super Hubs)
• 67 – UDP                      (Virgin Super Hubs)                                                    
• 68 – UDP                      (Virgin Super Hubs)                                        
• 123 – UDP                    (All routers)     
• 500 – UDP                    (All routers)     
• 1723 – TCP/UDP           (BT Home Hubs)          
• 4500 – UDP                   (All routers)     
• 33434 – 33445 – UDP    (Virgin Super Hubs)

Please note that in the above list of IP addresses, the notation "212.183.131.128/26" means the complete range of IP addresses between 212.183.131.128 and 212.183.131.191

Your router also needs to assign the Sure Signal with a DNS (Domain Name Server) address via DHCP (Dynamic Host Configuration Protocol).

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 (Internet Service Provider).

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, After a power cut, my sure signal box now has light one on and the second flashing.  I had the same problem a few months ago and you checked things your end and reset something.  You got things working quickly last time, so I'm hoping you can do the same again.

Thanks, Sean.

I have a Sure Signal that's worked perfectly for several months and today it's got a solid red light and a flashing white light. Why? I've tried switching it off and back on, my BT homehub has port clamping enabled (although as it's been fine for months I can't see what else can have changed).

Still no sure signal since Saturday.  Down to just the power light now. Would someone please look into this for me? 

[SeanJ]

Just read on the sure signal support, after trying various things, you can phone 191 from your mobile for assistance. LOL.  Is there a land line number anyone?

[SeanJ]

Changed the power supply and was up and running within a few minutes.  Even though there was enough power to start the sure signal, there may not have been enough amps to get the 3g working, so I read in another thread.

Hi Matt_B

There is no port clamping option available on my router

Hi,

I have a version 1 Suresignal which has worked fine for several years now. Over the last week it has stopped working. Light 1 is solid while light 2 flashes. Lights 3 and 4 do not light up at all. I have gone through troubleshooting and reset the device etc but this has not worked. I have also phoned customer support with no luck.

I phoned my broadband provider (Sky Fibre) and they have said that there is no reason from their point of view that it should suddenly have stopped working.

Please could you look into this for me?

I saw on a previous post that you asked for some information so I include this below in case it is relevant to me.

Hi GraemeKettle,

Please try a different Ethernet cable and to ensure that all the following ports are open as follows:

Ports to be opened for forwarding

• 8 (TCP & UDP)
• 50 (TCP & UDP)
• 53  (TCP & UDP)
• 67 (UDP)
• 68 (UDP) 
• 123 (UDP)
• 500 (UDP)
• 1723 (TCP & UDP)
• 4500 (UDP)
• 33434 - 33445 (UDP)

IP addresses to be allowed on the router & firewall

• 183.133.177-179
• 183.133.181-182
• 183.131.128-191

Once the above steps have been followed please perform a reset:

• Unplug the Ethernet cable from the Sure Signal
• Locate the button on the base of the box next to the Ethernet ports
• Press and hold the button for approximately 30 seconds
• Once the lights come back on, release the button
• Plug the cable back in
• Allow around one hour for the Sure Signal to come back online.

Thanks,

Sarah
