Hi, a scan using my AVG app on my iphone and laptop has shown that my router is vulnerable because of a 'wide open' port (7547) and susceptible to potential hackers. Can anyone advise?
Fixed! Go to the fix.

@Mace1 Welcome to the forum.
This is a very old chestnut. Just do a Google search for Port 7547 and read all about it.
This port is used by Plusnet to update your hub firmware. This same technique is used by BT and I suspect other ISPs to keep firmware up to date.
In short it is nothing to worry about but if it's very important to you then you will need to buy your own third party modem/router.
Allegedly there is the equivalent port open on my Smarthub but when I try a proper external service that actually probes the port it is shown as either closed or stealthed. Try it with GRC's 'Shields Up!'.

Hi Baldrick1,
Thanks for quick reply. Problem 'solved'
I did a bit of surfing through Google as you suggested. I found someone (I think on Plusnet Community) who had found Shields Up. I tried it after ensuring that it was ok and it came back that all was ok. It was suggested that a regular check was advisable.
Thanks again

Hi Baldrick1,
I've just re-read your initial reply about my router security, and I've noticed that you referred to 'Shields Up'. Maybe if I had read your reply properly I could have saved myself time and effort.
Anyway, thanks again for your help
