What causes the wireless card to activate?

D

DGD

I have Windows XP SP2 with a D link wireless adapter that communicates
with a Microsoft MN 700 wireless router using 802.11g. Is there any
software out there that can tell you what particular program is
communicating wirelessly with the router? This computer is
periodically (about every 20 seconds) communicating with the router. I
am not downloading anything and I have no known applications open and
running. Is there anything out there that I can use to track down what
is causing this constant communication between my computer and the
basestation?

Thanks.

It is probably UPnP activity. You could log into the router and
check the logs there.

Not sure what you mean by UPnP activity. In any case here is an
extract from my router log. I have eliminated the IP addresses:

2008/06/07 23:49:08 DHCP Client : Request sent from 72.xxx.xxx.xxx to
99.xxx.xxx.xxx
2008/06/07 23:49:08 DHCP Client : Server response sent from
10.xxx.xxx.xxx to 72.xxx.xxx.xxx
2008/06/07 23:49:08 DHCP Client : Server response sent from
10.xxx.xxx.xxx to 72.xxx.xxx.xxx

This doesn't come close to capturing the amount of communication that
was going on and time line that it occured. My router doesn't appear
to track this in the device log.

Actually when I look at the computer in question, it is constantly
communicating with the router. I had orginally said about every 20
seconds, but my icon in the system tray for wireless communications is
constantly blinking and I can see my wireless router constantly
communicating with my external broadband connection.

Doug,
Looks like you've changed the addressing scheme, since by default
the MN700 uses 192.168.2.xxx addressing. do you want to describe
your network topology? You've got three ranges listed
99...
10...
72...

72 is likely Rogers, but not sure what 99 is.

without seeing the whole entries, it is tough to determine what is
going on.

note that there is a lot of probing, etc. present on the Internet.
the router should be stopping that with SPI. I'd have to see the
log of traffic to the computers IP to even guess on what is going
on.

UPnP - windows messenger and other programs use this.

2008/06/07 23:49:08 DHCP Client : Request sent from 72.xxx.xxx.xxx to

2008/06/07 23:49:08 DHCP Client : Server response sent from
10.xxx.xxx.xxx to 72.xxx.xxx.xxx
2008/06/07 23:49:08 DHCP Client : Server response sent from
10.xxx.xxx.xxx to 72.xxx.xxx.xxx

Thanks for the feedback. My router does use a 192.168.xxx.xxx
addressing scheme for the internal wireless network. The device log,
however, does not record any of the internal traffic. My ISP is
Rogers. I disconnected my wireless router from the Rogers box,
totally disconnecting and isolating my home entwork from the
internet. The wireless adapter I am concerned about continued to
communicate with the basestation, so there is nothing from the outside
seeking input. The wireless adapter continues to constantly
communicate. I have re-installed the wireless adapter, updated the
drivers and the same thing occurs. I am wondering if it has to do
with Microsoft messanger. The computer is my daughter's and she is
constantly using this program to "talk" to people. Can Messanger be
constantly polling the wireless router? I tried shutting it down, but
the constant communication with the wireless router continued.

I traced my problem back to my recently installed wireless printer.
It appears there is nothing wrong with the adapter. If i turn the
printer or the printer's radio off, all of the communication I see on
the adapter goes away. It was actually affecting two computers, both
of which I have set up to print wirelessly with my HP C7250 all-in-one
printer. Had a frustrating online chat with a tech support rep from
HP who insisted this is normal wireless behaviour. If there are no
print requests being made, why is the printer constantly communicating
with the computers (I am getting a transmission indication every 1 - 2
seconds). And it is the printer. I disabled all HP running processes
on one computer and the transmissions continued. They only stopped
when i turned the printer's radio off. Any ideas out there on what to
do apart from returning the printer? HP's recommendation was to turn
the printer's radio off and only turn it on when I wanted to print. I
have four computers spread out throughout the house. Most
impractical. Thanks.

is the wireless on the printer set up as DHCP or static IP?

I traced my problem back to my recently installed wireless printer.
It appears there is nothing wrong with the adapter. If i turn the
printer or the printer's radio off, all of the communication I see on
the adapter goes away. It was actually affecting two computers, both
of which I have set up to print wirelessly with my HP C7250 all-in-one
printer. Had a frustrating online chat with a tech support rep from
HP who insisted this is normal wireless behaviour. If there are no
print requests being made, why is the printer constantly communicating
with the computers (I am getting a transmission indication every 1 - 2
seconds). And it is the printer. I disabled all HP running processes
on one computer and the transmissions continued. They only stopped
when i turned the printer's radio off. Any ideas out there on what to

Doug,
Looks like you've changed the addressing scheme, since by default
the MN700 uses 192.168.2.xxx addressing. do you want to describe
your network topology? You've got three ranges listed
99...
10...
72...

72 is likely Rogers, but not sure what 99 is.

without seeing the whole entries, it is tough to determine what is
going on.

note that there is a lot of probing, etc. present on the Internet.
the router should be stopping that with SPI.  I'd have to see the
log of traffic to the computers IP to even guess on what is going
on.

UPnP - windows messenger and other programs use this.

The printer should be using an IP address porgrammed onto in via the
unit's console (aka static IP.) Depending on the DHCP lease time may
be set too low.

Also, any "enhanced" management console installed on the PC will
generate traffic.

The lease time is usually two weeks, but I will check later. The
traffic I am concerned about is coming from the printer and is
independent of any "management console" software installed on the PC.
I disabled all HP software on the laptop and this had no affect on the
amount of transmissions being received on the laptop. These
transmissions only stopped when the printer's radio was turned off.
I don't see the relationship between an auto or static IP address and
the amount of time the printer is communicating with computers. Why
would making the printer's address "static" make any difference to why
it constantly transmitting?

are you broadcasting the SSID from the router or is it hidden? have
you changed the SSID name on the router from the default?

what is the IP assigned to the printer? what is the IP assigned to
one of the computers ?
Click to expand...

The SSID is broadcast and it uses the default name (at least I think
its the default name. I've been using it for over 2 years). The IP
assigned to the printer is 192.168.2.102. The IP for the two
computers affected by the excess transmissions are 192.168.2.103 and
192.168.2.119. The range of addresses the router can allocate is
192.168.2.2 to .254. All computers can see the printer through the
router via the "ping" command. The lease time for IP addresses is two
weeks, as I thought.

change the SSID name from the default. it is possible that someone
else has the same MN700 and uses the default SSID in range depending
on where you live and depending, this can create havoc. are you
using WPA security?

all other things aside, the wireless in the printer should not be
constantly (every one or two seconds) communicating with the
computers. Are there other devices on the network besides the
printer and the two computers you mention ?

I am using WEP security on the network. There are no other networks
in my area with the same name as mine. I have used Netstumbler to see
what is out there. Although there are quite a few other networks out
there in my neighbourhood, all go by a different name. I assume a
network that does not broadcast its name would also show up, but
without an allocated name. I have also selected a channel away from
the majority of channels in use by these other networks.

I have two other computers on this network. One is a Mac Laptop and
the other is Windows XP machine. I have installed the printer on the
Mac but not on the other computer. I cannot see the transmissions on
the Mac in the same fashion I can on the other two computers so I
can't tell if it is receiving these constant transmissions from the
printer. The sole computer I do not have the printer software on does
not have these constant wireless transmissions ongoing. This constant
transmission is only there when the printer's radio is on.

Another odd thing that happens - when either of the computers that
have the printer software installed is booting up (and both seem to
take a long time to boot), I cannot access the internet until the
installed printer software completely initializes.

Thanks.

I was going to suggest that you try asking in the hp itrc forums, but I
see you just posted there yesterday. Did you see this thread (which may
or may not apply to your situation): http://tinyurl.com/3sgj5d

HP installs quite a few software modules when you install one of their
printers. The functions, operation, and side effects of these modules
are not well documented. Sometimes you can delete various exe or dll
files and sometimes you can turn off services with no noticeable effect
other than to eliminate some unwanted behavior -- but not always.
Sometimes you can substitute a more "vanilla" printer driver.
Unfortunately, when there are other hardware functions (e.g., scanning)
to consider, you may be more limited in what is possible.

In any case, determining *which* files are safe to delete and *which*
services may be disabled takes a lot effort.

As part of the troubleshooting exercised by HP Tech support, I shut
down all HP processes I could identify on one of the affected
computers. In spite of shutting down all of these processes, I
continued to have these constant transmissions from the printer. It
was explained away as being something normal, but I disagreed with the
tech support rep. I asked him to forward my issue to their
engineering staff and he reluctantly agreed to do so. The only
function I have discovered to date that stops the transmissions is the
disabling of the printer's radio, which is simply not practical.
Could there be a problem with the printer's radio? I had read
somewhere that HP had some production problems with the C7250, but
there was nothing specific identified.

The link that Lem posted seems down the right path. I'll have to see
if any of the things mentioned makes any difference, but I doubt it.
This issue seems to reside in the printer.

Thanks again.

The printer wireless settings have the authentication set as "Open".
Don't know how to change the setting on the printer and changing the
setting on the computers is somewhat confusing. If I establish the
authentication on the affected computers as "Shared" what can I expect
to happen, if anything?

Well, I tried to set the authentication to "Shared" on both affected
computers. Both lost their connection immediately and it took me an
hour to get everything working again.
