DNS problem invloving wireless network
I recently purchased a new laptop while staying with my Dad, and it connects fine to the wireless network I set up at his house. However while at my Mom's I cannot connect to any sites.

When I try to access a site I get the message Address Not Found- The browser could not find the host server for the provided address.

What country are you located in. Canada
Name of your ISP (Internet Service Provider).
Bell Canada
What is the expected Upstream/Downstream speed for your ISP Connection?
Sorry, I'm not really sure about this. But it does say that it is 100 mbs.
Make and exact model of the broadband modem. SpeedStream 5200
Make and exact model and hardware version of the router (if a separate unit). Linksys WRT54G.
Connection type, wired or wireless.
I have a wired connection between a working computer and a the network, and a wireless connection between my laptop and the network.
If wireless, encryption used, (none, WEP, WPA, or WPA2) none
Make and model of your computer.
The problem computer is a Acer 5920G.
Version and patch level of Windows on all affected machines, i.e. XP-Home (or XP-Pro), SP1-SP2, Vista, etc.
Vista is on the affected laptop, and XP Media Center is on the working computer.
The Internet Browser in use, IE, Firefox, Opera, etc. Firefox

Basic connectivity tests show that my default gateway appears to be offline.

In my network and sharing center it shows a diagram like this.

BR-PC (This Computer)=========linksys====X=====Internet

If I click on the X to diagnose I get a message that says it "Could not automatically detect network's settings, The network took too long to return its web proxy configuration." I don't think this is the same error message I got last time, which was about there being a DNS problem, and that it tried to connect to well known site www.microsoft.com and was told it didn't exist etc etc (sorry that I can't get the exact text up anymore, but its a pretty common one so I think you would know it.

I'm new to working with wireless networks, so I assume I am missing something basic.

Thanks in advance for the help!

Hi and welcome to TSG
What is the ISP at Dad's house?
Also an

ipconfig /all when not able to get into the net,might be helpful here

Like so:

On any affected computer, I'd also like to see this:

Hold the Windows key and press R, then type CMD to open a command prompt:

Type the following commands:

PING 216.109.112.135

PING yahoo.com

NBTSTAT -n

IPCONFIG /ALL

Copy and paste the results back on this thread.

The ISP at my Dads house is the same, Bell Sympatico.

The internet won't work on the laptop, and I don't have my USB key, but Its not that long so I guess I can type it.

Microsoft Windows [Version 6.0.6001]
Copyright (c) 2006 Microsoft Corporation. All rights reserved.

C:\Users\My Files>PING 216.109.112.135

Pinging 216.109.112.135 with 32 bytes of data:
General failure.
General failure.
General failure.
General failure.

Ping statistics for 216.109.112.135:
Packets: Sent = 4, Recieved = 0, Lost = 4 (100x loss),

Then for Yahoo.com

C:\Users\My Files>PING yahoo.com
Ping request could not find host yahoo.com. Please check the name and try again.

I tried it with and without the www. and it made no difference.

Also, how would I ipconfig/all? That's just another command, right?

Yes:
ipconfig /all

Is the router the same at Mom and Dad's or are these different routers?

Can I assume that there is not a working wireless net at Mom's?
And,a dumb question,because I don't know.can I assume that Bell Sympatico is a DSL provider?

If you have any firewalls running on either pc,disable them,try connection and see if the result is the same.Re enable after test.

"If wireless, encryption used, (none, WEP, WPA, or WPA2) none"

None would be the wrong answer. Hopefully you didn't setup your Dad's wireless like that or you put ALL of his wireless traffic available to anyone with a wireless hack setup.

You don't mention setting up your moms wireless so I have to assume someone else did.

Either they setup the routers wireless with an encryption key or it is not enabled. You would either need to get into the router to view the encryption key or enable wireless and enable the encryption key [wpa2 is the best - don't use wep as it has already been cracked] or get the person who setup the router to walk you thru it.

You can't ping via the internet until you have a physical connection to the wireless router. You will know you have a wireless connection when you can ping the gateway ip.

PS. this is not a DNS issue.

I'm not sure if they are both the exact same models, but I do have Linksys routers at both houses. The ipconfig/all is a little long to type out, I will have to make a quick stop at my Dads to get my USB key. I should be able to post inside the hour.

And yes, I am pretty sure Bell Sympatico is a DSL provider.

wanderer2: I did setup both networks (or tried in my moms case, looks like it isn't working perfectly). I was under the impression that the person who would have a wireless hack system would have to be in range of the router, and there aren't other houses in range of it.

Is this correct? Or can they somehow access the connection to my router over the internet?

You lost me a little with the last part. Sorry, I am a bit new at this.

This is basically me explaining what I think Wanderer2 is talking about.

When you do a ipconfig /all there are a few very important bits:

IP address (that's what your current machine is called on your personal network)
Default gateway (that's what your router is calling itself)


If you are connected wirelessly to your router you'll get both an IP address and a default gateway. If you don't get a default gateway and your IP address is 169.254.x.x you're not connected to any device and need to troubleshoot the computer -> router connection.

However if you have a 'good' IP and default gateway then you need to troubleshoot the connection to the internet. And by good I mean you can see the default gateway address and when you do a ping xxx.xxx.xxx.xxx you get 4 sent 4 replied 0 lost. (that means there's 2 way traffic).

If you don't get 2 way traffic odds are its a software firewall.

As rorexc indicated,now ping the router from your laptop.

ping 192.168.1.1

Should get 4 good replies.

And,if encryption is not enabled,anyone with a laptop,searching for a network,will find yours,perhaps unprotected.
The way you can get infected/hacked over the internet,is by having no or non current anti spyware/antivirus protection,Your router acts as a hardware firewall.

Could you give us the model # of your speedstream.Found some perhaps interesting info about 5200's but want to make sure that it may apply to you.

I have current Antivirus and Anti Spyware programs, and lets just say there isn't anyone who would be in range of my router. I live way out in the boons, lol.

Something like E5402 or 0001 I believe.
