Lets start by making sure the Linksys is connected to
the net and then troubleshoot the Wireless.
You mentioned no internet connection, but do you have
a LAN connection? If you have at least one cabled
connection to the linksys then get back into the router
admin pages.
(If you have only wireless then check the things
ReWrite said as far as proper ip setup on DHCP or
static by using ipconfig /all. If it appears that you have
gotten an ip then try to get back into the admin pages
with the wireless)
Once into the Linksys setup pages go to the Setup /
Basic Setup page.
If you are on DSL I would guess it is PPPoE so check
that the Internet Connection username and password
are correct for your DSL account. The Linksys will do
the PPPoE login that your DSL software on the PC
used to do.
If it is not PPPoE, lets say static, then check your ip
setup in the router.
If it is DHCP with no Login (Like cable companies use)
then there may be a requirement for the DSL to have
the specific MAC address from the PC NIC. The Linksys
will allow you to clone the MAC onto the Linksys. This is
normally a cable issue and not DSL though.
Make sure you hit the APPLY button if you change
anything.
Then find the Status Page. If it is PPPoE there is a
Connect or Disconnect button. Try to connect and see if
you get a public ip. You can then test the connection
from the Linksys Diagnostics Page.
Once that works and the Linksys and/or cabled PC can
get on the NET then chack the wireless. Try it first with
SSID broadcast on and no WEP or the like. Once you're
on then ttighten the security down.
Good Luck,
