OK. Confirm your P C has successfully updated the microsoft patch. Go to Control Pannel etc and check that the update has been succesfully installed my (borrowed) Win 8.1 PC failed to install a KB.. last friday and I only successfully installed the update on Sunday.
Checked - shows fine
The next port of call, your Router can you let the PPRuNe illumni know the details please and any relevent info... e.g Firewall Status/Type and any unique settings etc - Are you running Norton ?
Error on the Virgin Cable router (rebranded NETGEAR - not sure of model number) and the Talk-Talk D-Link SSL-2780.
Yes running Norton - Norton firewall active but can't see any settings taht would cause this
NB BT are progressively updating their firmware on their Home Hub routers to counteract a potential internal net i.e. within your home network, vunerability, re the heart bleed open SSL exploit.
N/A I asume
Try re setting the router by switching off leaving for a minute or too and then switching it back on and leaving it to re-establish your connection.
Done - both routers (twice each)
Try another browser. Are other P.C's/phones OK on the network. [Edit: Ignore I mssed you comments.]
Can't get another browser downloaded until I can get on internet to download (hence I discovered that IP address didn't work either when trying to obtain Chrome)
Is your PC Wi-FI still working - try the usual windoze checks on your hardware. Does it have a thumb switch to disable the Wi-fi (Dell Vostro ??? )
Yes accessing the other machines and shared network storage device (with intranet) wirelessly
Lots of possibles.....
