Seeing the laptop's activity light forever flashing I ran TCPEye to see if it was network activity and found that it is repeatedly connecting local ports, e.g. 49768 - 49847 to 'routerlogin.net:ssdp'
I've run anti-virus scan and Malwarebytes but nothing untoward was detected. I've tried Google but not seen anything similar mentioned.
The 'puter's running Windows 7 HP 32 bit and connects to the network by wifi. My desktop 'puter running win7 64 bit and wired to the router does not do this.
Any ideas what's going on?
