internet connection not working (help!)

[Effty]

I have two computers at home, both XP, on a fairly new FIOS connection.
It goes through a router, and both PCs are wireless. Last night I
left one running, and shut the other one down. The one I shut down is
not connecting now. The one I left running is just fine.

My virus and spyware detection rules are up-to-date. AVG free and
Spybot S&D respectively. I ran both, both are clear.

Here's the weird thing. The little XP bubble says that my connection
is connected, and my signal strength is excellent. I've tried
refreshing or repairing the connection. It finishes to say the
connection is repaired, refreshed, and (again) excellent. I
disconnected, and reconnected with the network key, and (again)
everything looks fine! Several restarts, again (according to XP)
everything is fine.

I've tried Windows Explorer, Firefox, core ftp, games, a number of
update utilities, etc. Everything times out, as in it won't find the
server. This happens even with the software firewall disabled.

I haven't changed any of the settings. I do download a lot of stuff.

Here's the question. What would you look at next, to try to isolate
the problem???

Any ideas?

I'm kinda out of my element here.

Thanks!!!

On the affected PC, open a command prompt and do this:

ipconfig /release
(wait about ten seconds after the command completes)
ipconfig /renew

From the affected computer:

ping 192.168.1.1 (usually the gateway port on your router, YMMV)

If successful, your PC is communicating with the router. Try and
Internet ping:

ping google.com

Report back.

Okay. Weirdness still occuring. Did release and renew. Again, the xp
bubble pops up and tells me I'm connected excellently.

my ip addy shows as 192.168.0.100
subnet mask normal blah blah
default gateway 192.168.0.1

ping 192.168.0.100 shows 0% loss. Everything times at 0ms.

ping google.com shows "could not find host"

everything else, ping command-wise shows 100% loss.

So the affected PC is communicating with the router just fine, right?
I just can't find the internet...

Hmmm...

Hi Effty,
Try to clear the Cache and Do Ipconfig/release or renew
shut down the router and the pcs,give it a while and power up the router and
the Pcs,and see if that help solve the problem.

My guess is DNS issue.
good luck

I will have to learn more about this DNS thing!

Thank you.

Have you powered off your router and let it reset? config menu and see who
is connected, pc# 1 and PC#2...if 1 is and 2 is not, try another port on
rear of router...

 

[MikeG]

oops ...you said both were wireless....disregard trying another port in back

Actually, that was my first thought. This router doesn't have a power
button. You have to unplug it!

I learned the hard way that if you press the indented reset button on
the back it wipes away all the firewall rules you constructed via the
web interface. It actually resets it to factory settings! Unplugging
it doesn't seem to have this effect.

The issue is on the Client PC, probably an issue with the TCP/IP Stack.
I would run a Winsock fix utility on the PC with issues and see if that
helps resolve it.

It the system using default windows config or manually
configured?

Open command prompt and type "IPCONFIG /all".

Does it show the DNS entries correctly as your other system
does?

Try pinging the router, typically it'd be 192.168.0.1
(gateway is same as router for your purposes).

If that works too, still at command prompt,
"tracert yahoo.com"

Where does it end?
Try pinging an IP #.

Are you letting this system go into power management modes?
some old nic drivers don't do so well at that, if it works
until it goes to sleep then try a newer driver.

You were pinging yourself there. Try "ping 192.168.0.1" instead. The
gateway (your router) generally has 1 in the 4th octet..

So DNS is busted. It sounds like the computer cannot reach a
DNS server, and cannot translate "google.com" into 64.233.167.99 .

Another potential source of interference, could be the
contents of the "hosts" file. On some OSes, the "hosts" file
is used to store local translations. It can also be used to
redirect your browser. For example, if you map doubleclick.net
to 127.0.0.1 in the hosts file, then a request to go to
doubleclick from your browser, will cause the computer to
"consult itself", causing the request to fail. While I doubt
your hosts file has been filled with garbage, it is another
place to look if something times out on you.

Thanks everybody. It seems to be working now.

I din't know about the "tracert" command. Thats a pretty interesting
one. I'll have to remember that.

I'm going to read up on DNS and hosts files. Networking seems like a
rather shady subject to me at times. One computer resolving DNS and
the other one not doing so kinda threw my head for a loop. I have a
feeling that I'm still not properly grasping the concept.

In my mind, the windows XP "repair connection" should have worked for a
DNS issue since that's supposed to flush cached information, no?

It's possible that the root cause is my hosts file since my software
firewall (Kerio Personal Firewall) has ad blocking, which I guess would
change that file in some way. Like I said, I have to read up on that.
I understand that file is a hot commodity when it comes to viruses and
spyware.

Anyway...

Thanks again.

Cheers!

Any ideas?

Yes, Step 1 ... See if you connect to the router from the PC.

From the working PC, open an MS-DOS command prompt, type ipconfig /all
and note the Default Gateway. That's your router's IP address on your
LAN, eg: 192.168.1.1

Go to the unworking PC, open a web browser and enter the Default Gateway
IP address from the working PC, eg: http://192.168.1.1

Hello my friend had the same problem what I did was the very things you
did at first. stomped my self I decided that I know my computer worked
a few days ago such as your case and out of desperation I tried system
restore. I would recommend trying system restore to take it back to a
day you know it worked. This might save you alot of trouble shooting
time. In my case the driver was causing the trouble but didn't know
what to do so I did the restore and it worked fine.

thanks administer of god
