Sure Signal V3 only works intermittently

[stevewoods]

I have used my current sure signal v3 for the last couple of years without any problems. Recently, both my handsets have only worked intermittently sometimes showing no signal but other times showing a full signal. On the sure signal, the power is solid red and the internet and service lights are solid white, indicating all is well.

I have tried powering down the sure signal several times and then it comes back on with the correct lights showing but still no signal on the handsets. I've also tried resetting the unit by holding down the reset button for 30 seconds. It went through the initialization routine and then was back up in about 20 minutes although the handsets still do not show any signal.

I have run through the troubleshooting section and the results are as follows.

Speed test - download 63.45Mbps - upload 18.88Mbps

Ping test - Line quality B* - ping 15ms - jitter 1ms

External IP - 80.229.5.171

I'm noticing the same thing over the past couple of weeks. It can change minute-by-minute. The associated router & Internet connection seem very stable. I noticed it because the number of "You have missed a call from..." texts increased plus it's often not possible to send a text ("No network signal" message) but five minutes later it's sent.

Very irritating!

Bizarrely, mine tends to not work in the morning but then is fine during the afternoon and evening. It is working now with max signal strength although the traceroute still times out after the IP 166.49.211.254 step - is this correct?

[Nefeco]

My traceroute did get to a server with Vodafone in its name, but then hops started to fail once "inside" Vodafone and the tool reported that it was assuming it'd hit internal firewalls, so stopped trying further.

But at least it showed it reaching Vodafone...

@stevewoods

I've processed a resync of your Sure Signal.

Please wait 6 hours and then reset the device. 

Let us know if you're still having the same issue after this. 

@Nefeco

Are you still facing issues? If so, please let us know your Sure Signal serial number.

Thanks @Sukhi - mine seems okay today (I've done nothing to change it) - I'll get in touch again if it seems like it's acting-up again... Nefeco.

[stevewoods]

Thanks Sukhi. I'm not at home until tomorrow so I'll do the reset then and let you know if I have any more problems.
