Laptop suddenly stopped connecting to Internet

Hello

We have a NetGear RangeMax Wireless Router attached to a Comcast cable
modem at one end and our desktop PC at the other. We have set up a
secured network using the router.

My wife and I use our respective laptops to connect wirelessly to the
Internet using this router. This has been working for several months
now.

Since yesterday, for no apparent reason, my laptop is unable to access
the Internet using the router. Our router shows up in the list of
available networks and my laptop has an 'Excellent' connection with it.
However, when I open up my browser it does not connect to the Internet.

My wife's laptop works fine and does not have this problem.

Besides other secured networks, my laptop is able to see a couple of
unsecured networks in the apartment complex where I live. If I connect
to them, my browser works fine and can access the Internet.

Any suggestions on what may be going on here ?

One thought I had was to somehow delete all knowledge about our network
from my laptop, and then let it find the network again and for me to re-
enter the password etc. to set it up afresh. However, I do not know how
to delete this info from my laptop. Any suggestions on how to do this ?

Thanks.

So there is nothing wrong with the card.

The problem is with the router. Have you done a hard reset of the router
and let the procedure reset all router settings back to their out of the
box states. It might correct the problem.

What's ipconfig /all say when run from the command prompt? What does
ipconfig /release followed by an ipconfig /renew do? I wonder if
your dhcp server is just unhappy on the router.

Have you done the obvious of rebooting your machine and power cycling
your router?

Double click your wireless icon down in the task bar. It should pop
up the utility that is managing your wireless profiles, and there is
usually a way to delete existing profiles. Without knowing whether
your laptop uses an OEM program for that or Windows zero config to
manage wireless profiles, no one can give you a definitive click
stream how to do that, so you may have to experiment.

Thanks a lot.

Powering off the cable modem and router (they are both connected to the
same outlet) and then powering them on again solved the problem.

All is well.
