I think there's no avoiding the fact that the router appears to have died :( I even went to PC World to buy a new router on the day this all happened... but the chap there told me that Sky Broadband wouldn't work with a router other than one supplied by the ISP themselves... this sounded odd to me but I wasn't really keen on wasting money on a new router if this was true. Do you know either way?

No... it's a single unit provided by the ISP... And the internet light has not lit at all since this started...

Yes DHCP Server is enabled on the router... I've tried the host on a static IP and a dynamic IP... same problem either way.

The loopback ping works fine... as does the ping of the router (192.168.0.1). The router complains that it can't reach the destination 192.168.1.1 as you'd expect. And tracert http://www.google.com returns a message "Unable to resolve target system name www.google.com" Connecting devices by ethernet activates the LED on the router to show there is a device connected but the internet light remains stubbornly dark!

Sorry... I should have been clearer... there is no wireless adapter on my pc... it is only connected by ethernet direct to the router. My smartphone and PS3 connect wirelessly. No response to pinging google.com by name - or by IP 8.8.8.8. I tried pinging from the router control panel earlier too - same result. Pings from the host to the router itself resolve fine (of course) The router is a Netgear DG834GT... I truly appreciate your patience on this one!

Everything in Device Manager appears to check out - there's one network adapter listed: Broadcom 440x 10/100 Integrated Controller. Claims to be working properly. My PC, connected by ethernet, and my Galaxy S3 and PS3, connecting wirelessly, can all see the local network but not the internet. I can try connecting my S3 via USB I guess if you need any more files from the PC... And yes... I have rebooted the router several times (including a factory reset) but no effect. Interestingly, the Vista "Diagnose and Repair" option indicates that the "Primary DNS Server is currently online, but is not responding to connection attempts at this time" - some kind of authentication problem?

I can't post logs without internet access... I'm on a mobile device via 3G atm... not the offending computer... For the record though, running MBAM was the first thing I did... it came up with two trojan infections when I ran it from command prompt during the infection... and nothing now. Incidentally, removing the files with MWAM didn't fix the original infection.... I ran a full scan last night and a quick scan now - nothing found. I should note, though, that the database is several months old (and of course I can't update without internet!)

Can anyone help? My wired and wireless devices can all find my home network - but the router can't connect to the internet... This all happened after infection by some ransomware (which I finally cured by rolling back to a restore point a few days old) - but I can't see the connection between this and the router... I've tried a different ADSL filter - same problem... ISP tech support were no help... *Does anyone have any ideas? Could the infection have somehow damaged the router firmware? And if so, how can I fix it?
