A friend has just bought a new lenovo S10e with windows Xp preloaded and wireless ready.
I set up the the wireless LAN to join her peer-to-peer network and was able to access the internet immediately.
No antivirus came with the machine, so downloaded AVG free from the internet and installed it.
Then when attempting to update AVG, internet access was no longer available.
The machine still detects wireless networks and is still connected to her LAN. Why has internet access been lost? This happened to me once before and only "solved" the problem then by linking a cable between wireless router and PC.
I'm missing the fix for this which I suspect is simple(!)
