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

OK before I have a nervous breakdown can you please, please help me sort out my Sure Signal that hasn't worked for some weeks. I use a BT Home Hub 2.0 and the serial number of the Sure Signal box is 21222426369. Am totally untechnical but need all the help I can get before the Sure Signal goes through the window. Grateful thanks in anticipation.

Hi dereksilsoe, 

I've done a resync for you, please do a reset to complete the process;

1 - Hold the reset button until all 4 lights are solid. Don't let go of the button until step 4

2 - Remove the power cable then the LAN cable

3 - Insert ONLY the power cable

4 - When the lights flash 1, 2, 3 then 4 release the reset button and wait for the unit to boot (5 minutes should do it).

5 - Insert the LAN cable and wait 

If the issues persist please supply the following information;

Your speed test results from here.

Your ping test results from here.

Your external IP address from here.

The results of a traceroute.

VSS Traceroute command

On a PC:

Click on Start and select Run

Type CMD into the Run box and press enter/click ok

A black box will appear.

In this box type tracert 212.183.133.177 press Enter

This will help us get the quickest possible resolution for you.

Thanks

Hi SureSignal support,

I'm trying to resurrect a version 1 SureSignal that worked just fine for 3+ years, but appeared to stop working a few weeks ago.

Symptoms are: first light solid, second light constantly flashing.

Unit serial # is: 21223129558

I have tried de-activating via the Vodafone website and then activating again, to no avail.  Please could you check whether the unit is reaching your (ie. Vodafone) servers and if a "resync", or similar, is required?

Many thanks in advance,

Adrian.

Thanks Kay.

I've done this, and waited overnight - however it has made no difference.  Still no joy.

Are you able to confirm when this particular SureSignal (serial# 21223129558) is managing to contact the Vodafone servers at all?

As an aside, I think the timing of our problems with SureSignal coincided with the recent work being carried out by BT OpenReach when they replaced our local cabinet as part of their FTTC roll-out (although note that we are still on standard BT Business ADSL for now - ie. PPPoA).  Might this be the cause?

I've noted on other threads the conversation around MTU setting of 1500 being a requirement for the SureSignal (which also allegedly adds the 'do not fragment' flag onto packets).

FYI, I can ping our modem/router with 1500-length packets (1472 bytes  + 28 bytes for IP headers = 1500) and the 'do not fragment' flag set, but not the next host up the traceroute stack - as follows:

ping -f -l 1472 10.10.1.1

Pinging 10.10.1.1 with 1472 bytes of data:
Reply from 10.10.1.1: bytes=1472 time=1ms TTL=63

Reply from 10.10.1.1: bytes=1472 time=1ms TTL=63
Reply from 10.10.1.1: bytes=1472 time=1ms TTL=63

Ping statistics for 10.10.1.1:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 1ms, Maximum = 1ms, Average = 1ms

ping -f -l 1472 host81-139-128-1.in-addr.btopenworld.com

Pinging host81-139-128-1.in-addr.btopenworld.com [81.139.128.1] with 1472 bytes of data:

Ping statistics for 81.139.128.1:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

.. and yet when I reduce the size of the packets to 1480 (ie. 1452 bytes, plus 28 bytes for IP headers), the ping succeeds:

ping -f -l 1452 host81-139-128-1.in-addr.btopenworld.com

Is this relevant?  Does this look familiar to you, or anyone else?  Might this (the MTU of 1500, plus having the 'do not fragment' flag set on packets) be causing a problem with the SureSignal connections to Vodafone servers?

Do let me know, as we need to sort this out.  Otherwise, we'll be forced to switch to another mobile provider with better coverage - without the SureSignal our Vodafone signal is pretty much non-existent.

Thanks in advance for any light you can shed on this.

Hi aw1978,

Your Sure Signal connected to our servers on 13 June at 4.28pm.

It’s possible that the maintenance work could have affected the Sure Signal’s connection.

Having the ‘do not fragment’ flag set may also be contributing to the issue.

Try removing the flag and allow packets to fragment to see if this helps.

When you’ve changed the flag, reset the Sure Signal:

• Hold down the reset button until all the lights show/flash (about 30 seconds)
• Keeping the reset button held down, remove then re-insert the power lead
• Once all the lights display, release the reset button
• The Sure Signal will come online in about an hour

Thanks,

Andy

This is driving me crazy! Box works for a few weeks then has a wobble, this last wobble had lasted at least 5 days, have reset. It will come back on for a minute then both lights flash and it goes off to reset its self a again. ISP is plusnet, broadband working fine. Serial number 40113858035 v2 I am a business and domestic customer with no phone signal, not happy, again! Can you re sync please?

[DaveCD]

Hi skennedy,

I've refreshed the location and resynched the Sure Signal.

If you're still having issues, please try it at another location such as a friend or family members.

[skennedy]

Hi DaveCD
thank you but that has made no difference! If i take it elsewhere won't i need to deregister and reregister? That all seems a little ridiculous! What else can i do having no signal is getting tedious!
Many thanks
