Calling all network guys...
 

I have a problem with my wireless connection. It is really a packet problem in that when I reach a certian amount of packets, the "sent" packets jumps to 1,400,000 packets and then to 4,300,000 packets every 5 seconds. This kills my internet connection (still connected to the router, just no websites, etc.) and I have to restart.
Any clues?
Intel Centrino 1.3 GHz
512 MB DDR SDRAM
IBM R40 Laptop
Cisco Systems wireless car inside laptop


I ran SpywareBlaster, nothing.
Ran Adaware 6.0 Professional....nothing at all.

run ethereal and see what packets its sending before it dies, its probably overkill and it might take you a little get used to, but its worth it, and it'll help us diagnose if its software , hardware etc


netstat -a might tell you a bit

you'll need winpcap too

its possible someones ddosing you i suppose, and the packets are replies. check your firewall

ps they did bring back family guy.

Thanks

Well I have both those programs installed but I cannot find where they were installed or if they do anything at all.
Anyone other ideas?

umm, it should be under Ethereal in the programs menu ? or
C:\Program Files\Ethereal

Found it but I have no idea how to use it...
But I have found a connection between KaZaA Lite and the internet cutoff. Sometimes KaZaA will only be on for 2 minutes and the internet dies, other times 20 minutes. I checked and I was up to 60,000 packets with the internet still working (no KaZaA running at all).

It seems to be KaZaA that is killing the connection, any reason why this would happen?

unfortunately ive never used kaaza , all i can think of is that some how its upsetting the network drivers, so check for updated drivers.

p2p stuff sometimes gets a little bit overwhelming... thousands of connections etc. overloads weak tcp/ip stacks and causes things to die. Maybe kazaa has some way to limit the number of connections you get from peers? (I've also never used it.)

The only problem is I have two computers: one desktop and one laptop. The desktop is hooked to the cable modem and the wireless router directly and the laptop is connected wirelessly. The desktop computer has never had this problem at all in the many years I have had broadband. Not a single problem with KaZaA just stopping. The laptop is happens all the time....that is why I am confused.

What version Aironet card do you have installed? The 340 or the 350?

What version of ACU are you running?

Go to Commands, Status and tell me what version NDIS driver, firmware and bootblock you have.


Mr Mephisto

I'm presuming your problem is solved then?

Mr Mephisto

Not sure about those Mr Mephisto, but talking to people at my school it is simply the netword card (Cisco) getting overwhelmed, and that disabling and re-enabling the card restarts the packet count. I guess a problem I will just have to live with for another 6 months.

soccerchamp,

This should not be happening to your Cisco card. I work with a deployment of over 34,000 of these and haven't come across this. You shouldn't have to simply disable and re-enable your card.

If you check the versions of your ACU (Aironet Client Utility) and the firmware & driver, I will be able to tell you if you're using the latest ones.

Mr Mephisto

Try upgrading to the latest drivers/firmware for the card (assuming you don't have them already), to see if it helps out any. You might get lucky.

Well I could not find anything in the ACU but I used Windows to update the driver (the old driver was 2002 and the new one is 2003) so I will wait to see if this helps. Thanks all for your help

It sounds like you're using XP to handle your "wireless networking."

Cisco produce their own client called the Aironet Client Utility (ACU)which you can download from here: http://www.cisco.com/public/sw-center/sw-wireless.shtml

This product is a lot better than XP's native WLAN networking capabilities. It will also allow you to check the firmware on the card, which XP software updates cannot do. You can also setup "profiles" for different wireless networks etc. I recommend it far and away above XP's networking facilities.

If you want specific help on how to install ACU, update your firmware, update your NDIS drivers etc, just let me know. It's easy enough.

Mr Mephisto

Well I have the ACU installed and had it before, I just didn't know how to use it.
I used Windows tool for updating the driver and last night before I went to bed I was downloading Terminator 3 and in the morning it was still going so the new driver appeared to have solved the problem so far.

OK.

Well if you want to know how to use ACU to check your card firmare etc, just let me know.
