Laptop WIN 7 Internet connection fails irrespective of physical location
Posted on 2012-08-22
Among other pc's and laptops we have a 10 month old Acer Aspire running Win 7 on a simple peer-to-peer network. It has been performing perfectly until 3 or so days ago. There have been no material changes as far as I can ascertain.
For no apparent reason it will no longer connect to the internet, although all other equipment does so. Diagnostics report a broken link between router and ISP, not so.
Moving to another physical network in another building gives the same result.
The DHCP server is mounted in the DSL router in both cases. Which ever network is used an IPv4 address is successfully assigned to either the wireless adaptor or the ethernet adaptor.
However, any attempt to ping either the router or other addresses on the network time out. The only time a result is obtained is when the laptop IP is pinged. I have disarmed the firewall for test purposes but to no avail.
All services appear to be running properly. What am I missing?
