I can not connect to the internet [Network and Web]

I currently have two computers (both windows XP SP2) connected to cable
internet through a Netgear WGR614v7 wireless router, which replaced my old
one yesterday, but the problem started way before that.

It started with a momentary blackout, which left my old router not working,
half a week later, we had some really bad weather (125km/h wind) which gave
me multiple blackouts, and, like normal, my router started working again,
(don't ask me why, it just always seems to do it.) a couple of days later it
finally went dead.

my problem is this: my second (newer) computer will no longer connect to the
internet. now there are some odd occurrence with this, the light on the
router shows up, meaning the computer is connected, but the router does not
say that the router is connected when you look at attached devices in the
settings. also whenever I turn the computer on, it tells me that the network
connection has 'limited or no connectivity' due to an nonrenewable IP, and
when i look at the values for the connection, it shows up the physical
address, it comes up as 169.254.202.29, rather than 192.168.1.3, as it should.

i have tried everything i can thing of, tested the Ethernet cable,
reinstalled netwwork adapter, new router, tried with different Ethernet
cables. but none have succeeded, does anybody have any ideas at all or should
i just try re-installing windows?

Power failures, especially those associated with electrical storms, can
and do damage computer equipment -- particularly computer equipment that
is connected to "the outside" (e.g., modems, routers, and network
interface cards).

Since I don't know what is included in everything you can think of, you
may have already done some of the following.

First, it doesn't sound to me as if reinstalling Windows will help you.

The symptom you describe (limited or no connectivity and an IP address
of 169.254.x.y) means that your NIC (network adapter) is set to obtain
an IP address automatically (generally a good plan) but the router's
DHCP server is not providing an IP address.

Assuming that your other computer is working OK, try connecting the
problem computer to the jack on the router into which the working
computer is usually connected. You may have to reboot or at least
"repair" the connection to see if it works. If this works, try one of
the other 4 LAN jacks on the router.

Try to use a static IP as follows.

- On the working computer, open a command prompt window and type
"ipconfig /all" (without quotes) and press enter. Make a note of the IP
address, subnet mask, default gateway, and DNS servers. Based on what
you've said, I would expect the first three of these to be 192.168.1.2,
255.255.255.0, and 192.168.1.1, respectively.

- On the problem computer, go to Network Connections, right click on the
Local Area Connection icon, and click on Properties. On the "General"
tab, select Internet Protocol (TCP/IP) and click the Properties button.
On the "General" tab, select the radio button to "Use the following IP
address" and fill in the fields for IP address, subnet mask, and default
gateway. The IP address you enter here should be the same as that for
the other computer with the exception of the value following the third
dot. Ideally, you should select a value outside the range assigned by
the router's DHCP server, but if you only have the two devices on your
network, it probably won't cause a problem. Rather than 192.168.1.3,
however, I'd suggest using a larger number, like 192.168.1.50. At the
bottom of the same window, select the radio button to "Use the following
DNS server addresses and enter the values you copied from the working
computer. OK your way out.

You shouldn't have to reboot, but if things don't work immediately,
reboot and try again.

unfortunately neither of these ideas worked, reseting the tcp/ip stack and
winsock did not do anything noticeable, while setting a static ip for the
computer did stop it complaining about having limited or no connectivity, it
ultimately did nothing.
