Wireless problems with laptop

[Bob H]

I have a HP Pavilion g series laptop which keeps losing its wireless
internet connection.

Initially it will connect to my router on 192.xxx.a.b and then out to
www land.

When I do an ipcongig /all, I get this:

IPv4 Address : 192.xxx.b.72
Default gateway : 192.xxx.b.b

Now as you may see this is a different IP address than what my router
is, so basically the ip address of the laptop and gateway address are
oputside the range of ip addresses here.

After about 10/15 minutes the laptop loses its wireless connection and
sometimes cannot connect at all.

How do I make the laptop see that its ip address is in the same range as
my router etc

Follow up.

I have given the laptop an ip address in the same range as other devices
and also given it the gateway address which other devices connect through.
I still cannot ping the router on192.xxx.a.b, and although I have a
wireless connection to the router, there is non to wwww.

 

[Char Jackson]

First, it's unnecessarily difficult to follow you because you haven't
provided any actual IP addresses. Addresses in the 192.168.x.x range
(presumably what you're using) aren't publicly routable so there is no risk
in sharing them when asking for help. If you're paranoid, provide dummy IP's
that you can map back to the real IP's.

Follow up.

Make, model, and possibly hardware/software versions of the router might
help to narrow things down. By chance, are you connecting to a guest network
that provides a time-limited connection by design?

Do other PCs exhibit the same behavior with this router? Does your PC
exhibit this same behavior with other routers?

I can't follow your a's, b's and xxx's - give us the real numbers. As
someone else has said, they are internal to your setup and don't need to
be secret!

What is the router's LAN address (which is what the laptop needs to use
as its gateway address)?

What subnet mask are you using? Presumably the router is set up to be a
DHCP server, and the laptop is set up to "get an IP address
automatically"? What range of addresses does the DHCP server dish out,
and with what lease time?

What DNS servers is the laptop using?

If all else fails, give the laptop a fixed IP address in the same subnet
as the router but outside of the range of addresses dished out by the
DHCP server.

Just a thought - you haven't somehow got *two* devices both acting as
DHCP servers and using different subnets, have you?

Ok, here are the real ip addresses

Initially it will connect to my router on 192.168.0.1 and then out to
www land.

When I do an ipcongig /all, I get this:

IPv4 Address : 192.168.1.72
Default gateway : 192.168.1.1

The laptop is a HP Pavilion g6 series with Windows 7 Home Edition installed.

The network is a unidentified network, and I have tried to change it
back to home network, but then changes to no connection at all.

I have Norton Internet Security installed if that helps.
Thanks

Norton Internet Security *RARELY* "helps"!

Thanks for mentioning that. It would be the first thing I would disable when
troubleshooting your issue.

It sounds like you have a neighbour who you're connecting to by accident.

Is that ipconfig data obtained while it's still talking to www land, or
only after it stops? If the latter, what happens if you do an ipconfig
/all immediately after connecting?

As others have said, it looks as if it's sometimes connected to someone
else's Wifi! Are you running any sniffer programs such as inSSIDer to
see what other networks are around?

Does the laptop need to move around, or could you connect it to the
router with an ethernet cable instead of using WiFi?

You don't need to mess with ipconfig etc. W7's wi-fi connection applet
will show you all available nearby wi-fi networks (this machine
currently sees 16!). It also shows the one you're connected to. If it's
not your own, then Disconnect and Connect to your own. That should fix
it, for the current session anyhow.

Your own network should be first in the list, which is ordered by signal
strength. If it's not, then moving the router (or computer) may fix it,
or you may need a new router and/or signal booster.

If the connection changes, than AFAIK, you are disconnecting and
reconnecting automagically. W7 connects to the router with the strongest
signal for which it has the password (key), or else for which no key is
needed. The latter appears to be the case. But why the connection drops
is a bit of a puzzle. Possibly it's signal interference, which W7 would
see as a disconnect.

As others have said, it looks as if it's sometimes connected to someone
else's Wifi! Are you running any sniffer programs such as inSSIDer to
see what other networks are around?

If you are indeed connecting to a foreign network, it is unsecured,
which is bad news for your neighbour. I'd get in touch with him and
suggest that he secure it. You should not be able to connect to any
nearby wi-fi network other than your own, and no nearby machine should
be able to connect to yours. Some cafes etc offer unsecured wi-fi
access. If that's your situation (do you live next to a cafe?), then the
only cure is to have a stronger router than they do.

Does the laptop need to move around, or could you connect it to the
router with an ethernet cable instead of using WiFi?

If you think that the best way to fix your problem is to start from
scratch, this is an excellent suggestion IMO. Using the E'net cable for
setup will prevent any inadvertent connection to a high-powered nearby
wi-fi network. It's also faster than wi-fi, which may be an useful for
other reasons.

Good luck.

Home network is not the same as the wi-fi network. Home network is
software (installed on two or more machines) that enable machines to
share data over any physical connection. Wi-fi network is just one of
the possible physical connections.

Use W7's wi-fi connection applet to find out what you are really
connected to. See my other post.

That was when the laptop was talking to www land ie ipconfig /all
No I didn't run any wifi sniffer progs, but I will do.

I did connect with a cable and all was well, but I want it to connect
with wireless really.

I have actually reinstalled the OS which is win7 Pro 32bit, so there are
no other programs on it at the moment, and it is doing exactly the same
thing as it was with other programs on, that is losing the connection,
so that's a reminder to put inSSider on next.

Also in Device Mangler there is a yellow exclamation mark against Other
Devices\ PCI Device.

I have installed AIDA32 to see what it could tell me about the PCI
device, and all it does say in Devices\Device Resources is that on IRQ11
there is a shared PCI Device and it has a yellow question mark against it.
Any ideas as to what that could be.

1) Go to Control Panel | Network and Internet | Network and Sharing Center.
2) On the pane at the left, click on 'Change adapter settings'.
3) Right-click on the wireless adapter and select Properties.
4) Click on 'Internet Protocol Version 4 (TCP/IPv4) in the list (but
don't un-check it) and then click the Properties button.
5) Under the General tab, select both 'Obtain an IP address
automatically' and 'Obtain DNS server address automatically'.
6) Under the Alternate Configuration tab, select 'Automatic private IP
address'.
7) Click OK/Close until you're all the way out.
8) Reboot and see if that fixes your WiFi connection problem.

If that doesn't fix it, the problem is then most likely with your router
configuration. The router may not be serving up IP addresses via DHCP in
the correct range.

Everest is the same as AIDA32, and it gives VEN/DEV info.

http://www.majorgeeks.com/files/details/everest_free_edition.html

This is an example screen shot.

http://imageshack.us/a/img594/7189/hvs.gif

The "Device ID" is VEN=109E and DEV=0878. I just
selected a PCI device on my motherboard bus at random,
for a demo.

Using this file, I can decode entries not known by Everest.

http://pciids.sourceforge.net/pci.ids

109e Brooktree Corporation
036e Bt878 Video Capture
0878 Bt878 Audio Capture

The Everest screenshot, has two BrookTree entries. One is
for the audio section of the chip, the other for the video
section of the chip. And the driver situation, is actually
a mess for that one. The best solution in that case, is
to download DScaler, as it does an excellent job with that
card The original Hauppauge drivers in the product box
were good, but the DScaler includes additional filtering
that makes the image look better.

Anyway, try the Everest, and maybe you'll get lucky.

Other than using some "driver finder" program, I know
of no (free) utility that is guaranteed to identify
everything. For example, if you have an ASUS ACPI object
from an ASUS BIOS, that one doesn't use conventional
plug and play, and is pretty hard to figure out. A couple
of the Asus "specials" can be resolved, by downloading
certain of their programs, then uninstalling the program
again. The driver the program installs, stays in place
and keeps Device Manager clean.

Since yours is a PCI device, I don't expect the
same degree of trouble.

*******

You can also try Windows Update, and just see what drivers
it has to offer. For my FTDI USB serial ports (RS232 connector
on the end), Windows Update offered a driver. So at least
that one thing was recognized.

In your screenshot there is a device which has [NoDB] next to it, and I
have a PCI Device [NoDB] using Everest Home

What is NoDB exactly...not identified or something?

Thanks

The more I follow this thread, the more confused I am. If your laptop is
connecting to an outside wi-fi network, you should be able to see that
in WP7's connection applet. Does the applet show connection(s) to
outside networks?

OTOH, the info provided by AIDA32 indicates a hardware problem. Since
"all was well" when you used a cable, it looks like the wi-fi circuitry
has developed a fault. I don't think using sniffers or ipconfig or W7's
wi-fi applet can tell you about that one way or the other, because those
programs show you only what's what while the connection is up. Finding a
sequence of different IP addresses (apart from the router's) is exactly
what you would expect if the connection drops and then goes up again.

So now I'm betting that you need a hardware repair. I'd take the laptop
to the shop.

Good luck.

"No DataBase entry available"

You then reach for the http://pciids.sourceforge.net/pci.ids
file and decode it yourself. Not a problem.
For the simple ones.

Everest gives you the VEN and DEV numbers (for PCI), so
you can look them up.

That's not the whole story, but you said PCI, and here we are.

*******

I knew this would happen eventually. It looks like Everest
was sold off, and the name changed again. You can try
the eval from here if you like. I bet the database in
it will be better than the old free one.

The laptop is now connected to a secure wireless connection to my
router. I know that because I have given the connection a unique name,
whereas before I wasn't sure what or where it was connected to. This was
due to guest ssid on my router was open and not secured, but is now.

In Win7's wifi applet there are currently 3 other networks besides mine,
but none of those show connections to this laptop.

Before you finish with the router, have you changed the password
on the router ? [If you do, stick a PostIt note on the router,
with the password written on it.]

Apparently, there are hacks available, where a person recognizes a
wireless router, by the nature of the default SSID used, then they can log
in using the known default factory password. This would apply perhaps,
to a piece of equipment receiving the absolute minimum of setup activity.

And it wouldn't be an issue, except for routers that support login from
the WAN side. As far as I know, my gear doesn't support that, but you
can never be too safe.
