Try this on your internet modem / router and let me know if this solved your issue. It helped my internet connection at home a lot.
1) Log into your modem / router
2) Turn OFF UPNP.
3) Turn off PC UPnP Service
4) Press: Windows-button a window should pop up. Write: services.msc then press enter.
5) In the list of services, scroll down to UPnP Device Host click it and press Stop service. Now do the same thing but with the service & SSDP Discovery
6) Exit the window and go to control panel > Network and Internet > Network and Sharing Centre > Change advanced sharing settings under network discovery, select to turn off network discovery then Save your changes
Please also enable the following online ports on your connection:
TCP: 53, 88, 3074
UDP: 53, 88, 3074
For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.
I'll give this a try and let you know how it works. Though I'm a bit perplexed due to the fact that the PC behind me, connected directly to the same switch I'm connected to, has never encountered this issue!
