Everything looks correct except the weird DNS ip address which I have
no idea where is coming from.
This network card is able to connect to other wireless routers. The
router is not defective as I have replaced it and am still
experiencing the same problem. Any attempt to override the automatic
settings on the router or wireless card do not result in any success
even if settings are identical to wired access which is working.
I have disabled all possible firewalls and anti-virus programs as well
as upgrading to the latest driver updates and trying to fix my
winsock. I tried connecting two other laptops but no success (both of
which happened to be Sony Vaio). I can access the router wirelessly
but cannot access the internet nor ping any ip address including DNS
with a success (aside from the router).
I have a feeling that this is a hardware issue with my wireless
network card which for some reason doesn't like the router. I've
posted in other places though with more emphasis on the router rather
than the wireless network card.
I have been trying to troubleshoot this for many days now and am at
the point of giving up and getting a different router/modem, though my
curiosity currently keeps me at it.
If anybody else experienced something like that, I'd appreciate any
pointers.
