If you tried a static IP address with no luck, just put the checkmark
back in the box to "Obtain an IP address automatically" on the TCP/IP
Properties page.
Let me recap what you've done/said so far and the logical inferences:
"I can connect to other neighbours networks fine" -- your wireless
adapter does not have a hardware problem and is turned on. This also
indicates that your TCP/IP stack doesn't have a problem (which might,
for example, have been caused by deleting some malware. I assume that
when you said that you "refreshed" the TCP/IP stack, you followed the
steps here:
http://support.microsoft.com/kb/299357/)
You get an autoconfiguration IP of 169.254.240.187 -- you are not able
to contact the DHCP server in the router. This is consistent with the
error message from ipconfig /renew (Do you also get this 169.254.x.x
address when you try to connect to the router via ethernet? I assume
the answer is yes.)
"There are 3 laptops connected to our router. Only mine has the problem"
-- your router's DHCP server is turned on and functioning properly
(assuming that the other 2 laptops are not set to have static IP addresses)
"I have tried connecting via ethernet to the router but get the same
problem." -- This is not a wireless problem but a networking problem.
There are only 2 things I can think of that would fit the above:
1. The router is denying you access based on MAC address -- this is
unlikely, especially if it is your router and you didn't set up this
layer of security. Also, if you were working OK for the past 6 months,
either your Vaio's MAC address was in the "authorized" list or MAC
address filtering was turned off. Still, if your router is unsecured by
an encryption key (very bad idea, BTW), someone else could have accessed
your router and altered this part of the router's configuration. Take a
look at your router's configuration pages. While you're there, check
out any other methods your router provides for filtering access.
2. Firewall. I know you said that "I also don't have a firewall
enabled," but perhaps there's something acting as a firewall that you
don't think of in that way. Recent versions of Norton AntiVirus, for
example, has "Internet worm protection" which acts as a sort of
firewall. Did you install a firewall or "internet security suite" and
then decide you didn't like it and uninstall? Some things are harder to
uninstall than they ought to be. Use Task Manager and identify ALL of
the running processes. Try "Safe mode with networking" and see if that
works.
