Cannot contact DHCP Server - Networking not working after upgrade from Windows Vista
Upgraded my Acer 4736G from Windows Vista to Windows Home premium 7 and was surprised to see how smooth the upgrade process was till i tried to connect on the internet and then Wham!!! 3 days ot reserach and no answers.
Essentially both my Wireless and Wired interfaces have IP address starting with 169.x.x.x.
Have tried everything under the sun and right now am planning a fresh install of Windows 7.
Not sure if Acer screwed up on the driver upgrade or this is good old Microsoft
with its rather in efficient Networking stack/tools.
Serves me right for not stcking to MAC/Linux at home and trying out a Windows laptop at home.
