Unless there is a cable outage in Strathmore Wellington, I have some cable issues.

I only noticed this problem after rebooting my router last night, it is possible that the cable was already dead and the two aren't related.

Last night I restarted my router due to connectivity issues between devices and when it came back up, my laptop wirelessly connected to the router but with the yellow limited icon [no internet connection] I checked two other WiFi enabled devices [Netbook & phone] which showed the same limited connection.  I used an Ethernet cable for a wired which had the same result, connected but without any data throughput.  

I factory reset the router and set it up again, no change.
I restarted the cable modem which came back up with all lights on solid green and link light flashing green but no data throughput.  connected an Ethernet cable from the laptop directly into the cable-modem which showed an orange link light but no data throughput.

Currently it is set up modem linked to router and all lights indicate that I should have an internet connection but there is nothing.  Has anyone had a similar issue?

What I have tried 
Reset the router to factory defaults. All lights indicate service. WiFi and LAN cable connect but no data throughput.
Reset the Cable-modem using the recessed button.  All lights come on to say I am connected and online but no data throughput either directly or through the router.
Tried a different WiFi router. Exactly the same symptoms as supplied one, so I am confident that the router is not at fault.

As all the lights are illuminated on the cable-modem, I assume that there is no physical issue with the cabling.

Only installed on Thursday, I hope this isn't a regular occurrence.
