No Connection using Vista -- XP Connections Fine

[Guest]

I upgraded to Vista home Premium in April, 07, and have had no issues with
connectivity until about 2 weeks ago. Now I cannot get any internet
connection through my Lynksis WRT-54G router (in turn connected to Comcast
Hi-speed cable) either wireless or hard connection. 3 other laptops using XP
connect with no issues. Attempted all recommended fixes in help menus, tried
removing updates to restore previous settings, tried various configuration
options (then put them all back), nothing works. Tried bypassing router,
shutting down laptop, modem etc. and plugging cable directly to laptop, even
that doesn't work. Any help is appreciated.

Is it possible that you have had a hardware failure in the wireless card in
that machine?
Have you removed/uninstalled the wireless adapter and let Vista
redetect/reinstall it?

Plugging your ADSL cable into the modem on your computer won't do diddly. A
dial-up modem & an ADSL modem are two different things.
Can you access the other computers on the network?
Can you ping 72.14.207.99? (Start -> Run -> type "cmd" -> click OK -> type
"ping 72.14.207.99")

Do this *before* you uninstall your network devices. That's a last resort
(before buying new stuff).

plugging a digital line into an analog modem port may kill the analog modem.
the ethernet cable from the DSL modem plugs into the WAN port of the router
or the LAN port on the laptop.

I tried this one first -- no, it responded ""Pinging 72.14.207.99 with 32
bytes of data. General failure (x 4). Ping statistics for 72.14.207.99:
Packets sent=4. Received = 0, Lost = 4 <100 % Loss>

I used a cat5 ethernet cable from the cable modem and plugged into the
correct port on the laptop, I believe, but at Doug said. that probably did
"diddly" (didn't give me a connection, anyway. Thank you both for your
reponses, I am pretty much a novice, and this has been frustrating to
troubleshoot.

That rules out a dns issue.
Find the IP of one of the other computers on your network & see if you can
ping it locally.
On the other computer, Start -> Run -> "cmd" -> "ipconfig"
one of those will be an "IPv4 address"; note it.
Do the process again on your Vista computer, but replace "ipconfig" with
"ping x.x.x.x".
Then do it the other way. Get your Vista IP & ping it from the other
machine.

If that doesn't work, uninstall & reinstall the drivers for your network
card.
Right-click "Computer"* -> Properties -> Device Manager
expand "Network Devices" & your network card should be listed there. Google
for the drivers on your working computer & burn them to a cd;
Double click on the device; click on the "Driver" tab & click "Update";
click "browse my computer" & select the driver from your CD.
Otherwise, follow the instructions on the manufacturer's website.

*formally, "My Computer"

I appreciate the detailed instructions in your posts. I have two drivers in
my Device manager, Broadcom 440X 10/100 Integrated Controller and Broadcom
802.11 g Network Adaptor. I copied both files to a disk, then using Device
manager, uninstalled each driver. Upon doing so, both immediately "installed
successfully". Tried reboot -- the Dell laptop with Vista connects to
router, but "local access only", no internet connection. Is there another
way to uninstall, then reinstall the files connected to my disc?

You can actually PING the router or connect to it to login? It's usually
192.168.1.1 or 192.168.0.1
My cable modem is 192.168.100.1. It varies a little by brand and model. If
all else fails, read the router manual.
I would make sure it has enough DHCP connections available. or even try a
fixed IP address.
It could also be other things, like a firewall setting or a security suite.
The first adapter listed is the NIC for the ethernet cable, the second is
the wireless adapter.

Hey NotMe and Doug -- thanks to you, I know have a connection -- first time
in over two weeks. The last post provided the clue -- it was a setting on my
security suite.PC-cillin, Internet Security 14 -- clicked "configure", there
is a button there which says "Halt Internet traffic". Had seen it before,
but since I wanted to restore internet connection, I never clicked it. I did
this time, and immediately got the connection back (Note: the button always
says that - but clicking it caused the unconnected arrows to connect).
It could be that the other tips you gave me also helped, but this worked in
the end. Thanks both for your responsiveness -- I hope another novice user
may finds this simple solution helps them one day.

 

[Doug]

Sounds like you fixed it all by yourself. Welldone.

Security suites & third party firewalls are known for that.
But since it worked for 2 weeks before quitting, I didn't think of that
first.
Someone must have changed that setting, albiet by accident or it was done
via an update or such.
I'm glad you're back online.
