Laptop WIN 7 Internet connection fails irrespective of physical location

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?

So it obtains IP from your router ok, but can't ping anything else but that IP?

What firewall do you have? 3rd party or just Windows builtin?

Sounds like something has gone wrong with the 3rd party solution(assume its Norton or something like that), can you uninstall it?

McAfee Internet Suite 2012 with firewall.  Tried disarming Firewall, makes not difference but haven't un-installed McAfee, will try that next, thank you.

Self solving.  McAfee issued a botched update.  Uninstalled and re-installed McaAfee.  OK now
