Re: Good wireless signal - but browser cannot find it?

Hello again,

I hope that this doesn't change anything but I thought I should inform you.

I have now removed Norton Internet Security from this PC and replaced it
with AVG free and Windows firewall. I found NIS 2008 difficult to work with
and had issues with it (as many others did, according to forums) hogging the
CPU. Subscription renewal was due next month, so I've got rid of it.

I still have the discs and licence and can reinstall it if it affects the
issue discussed in this thread.

Thanks, Shd

Thanks smlunatick, this sounds good.

But I have already tried it without the firewall and it still couldn't find
any sites.
To be on the safe side I have currently disabled all of Norton Internet
Security until I can I can get the PC on the internet, and the situation
remains the same, so I'm pretty sure the problem lies elsewhere.

Thanks for the suggestion, though.
Cheers, Shd

Hello again Steve,
Thanks for your patience.

Not such good results, this time.

Couldn't ping router - request timed out 4 times - Packets sent = 4,
Received = 4, Lost = 4, (100% Loss)

TCP/IP reset and rebooted. No change noted.

No firewall conflicts present.

But when I gave the command to see the route table, the text box briefly
flashed on the screen and then disappeared. I tried this several times but
without success. The text box appears full, but stays on screen for a
fraction of a second and then disappears. No chance to copy and paste - or
even read it.

Could this disappearing screen be a clue?
Thanks again for your help so far
Best wishes, Shd

Hello Steve,
Many thanks for reply, it's much appreciated.

Just a quick note to inform you that I can't do any more tonight as most of
the household has gone to bed (I'm in UK, it's 2am) and I can't access said
computer.

However, I will carry out your instructions tomorrow and post back the
results.

Thanks again.
Best wishes, Shd

Hello,

All our PCs are Windows XP and we have a Netgear router which sends out a
108mbps signal. All is working well - except:

We fitted a wireless PCI card into our son's PC to enable him to connect.
It installed fine, connected to the network - and the logo on the taskbar is
showing an excellent strength signal.
But his browser cannot find any connection and displays the error page
whenever we try to connect (on both Firefox and IE7). I have tried to help
them find it by using -Tools>Options>Connections>Settings - and checking the
'Automatically detect settings' box - but still nothing.
Yet network tests confirm that a good signal is reaching the PC?

This PC used to connect via an ethernet cable and recently via a USB
wireless device and never had a problem finding the connection.

The firewall is Norton - but disabling it temporarily made no difference.

I'm probably forgetting something very basic here, but I'm lost. I'm so used
to just plugging things in and letting Windows do all the rest!

Any advice appreciated. Apologies for rambling question. Thanks in advance.

Best wishes, Shd

Un-check the 'Automatically detect settings' box and all of the other
boxes in the LAN Settings window. They don't apply to your setup.

Please do these tests to help diagnose the problem:

1. Right-click the wireless network connection, then click Status >
Support > Details. What does it show for IP Address, Subnet Mask,
Default Gateway, and DNS Server?

2. Open a command prompt window (Start > Run > cmd), and type these
commands. Each one should receive four replies:

ping 208.67.222.222
ping resolver1.opendns.com

Hello Steve,
Thanks for reply.

Unchecked auto-detect boxes in connections and LAN.
The details for the network connection are as follows:

IP Address - 192.168.1.4
Subnet Mask - 255.255.255.0
Default Gateway - 192.168.1.1
DNS Server - 192.168.1.1

(Also, a DHCP Server was listed with same numbers as DNS Server)

Pings not so successful?

ping 208.67.222.222 - This received 'request timed out' message, four
times. Concluded with a summary - Packets sent 4, Received 0, Lost 4 (100%
loss)

ping resolver1.opendns.com - This received the message: ping request could
not find host resolver1.opendns.com. Please check the name and try again.

Any of this sound familiar to you? It throws me into deeper bafflement!

Thanks again for your time.
Best wishes, Shd

You're welcome, Shd, and thanks for giving the test results. They
show that your wireless network connection is getting the right
settings from your Netgear router, but it isn't able to access sites
on the Internet.

Can the computer ping the router? Try this command:

ping 192.168.1.1

Since the Norton Firewall is installed, make sure that the Windows
Firewall is turned off.

Resetting TCP/IP might help. Type this command, then reboot:

netsh winsock reset

If none of that helps, please post a copy of the computer's route
table. Enter this command, then copy/paste the contents of the
"route.txt" file:

route print >route.txt

I have seen this before and it was a firewall problem. I was using
Norton 360 v2 software which has an enhanced firewall module. Every
time I was trying my wireless adapter, I was getting strong wireless
signals but no access to the Internet or the router's internal web
pages. Turned out the firewall module needs to be told to trust the
router's LAN IP address (aka default gateway for the PC) and the
wireless router's SSID name.
