Old vs new hardware
 
ipw2200 not stable in Debian6! Is old hardware not stable? is old hardware not safer than new?

/Repet

Hi Repet and Welcome to LQ!
As a rule, old hardware is quite stable. I'm using a ZyXel wifi dongle that is probably older than your ipw2200 and it works fine. Can you explain what exactly the problem is and what driver you're using for the ipw2200?
ciao,
jdk

Old versus new is not a selection for stable would be my opinion.

Stability is a wide topic that covers hardware, firmware, software, configuration, power settings, maybe even things like emi/rfi, static, and thermal considerations.

Another issue is that a product that is produced each day may have slight changes to components. Even if the revision level doesn't change, some parts may cause slight changes in timings or power or whatnot that can cause the one device to act differently than a seemingly similar product. A revision level may also affect it's target use.

I do not remember any issues with Debian5
The problem is that I loos wifi connection. It is a strange problem. I am in the progress of testing what acctualy is hapening. Right now I tried a new approach. Usualy I am behind a VPN, vpntunnel.se. Berhaps I thought it is the culprit. Before I was the only one affected but a windows computer also lost its wifi connection. Before with VPN I was the only one effected. On those occations the firmware failed according to dmesg. Why would the router go dow only on the wifi side. As you can see I connected a hard cabel to the router before I rebooted it an that had internet. Also it looked as if the wifi was doing something, lamps blinking as they do under normal circumstances. Strange?

I've already tried old and very new hardware with debian and i've never got problem even if the hardware isn't supported it's a matter of time to get it working about one or two month. But old hardware is very stable yes.

I don't understand. Your output of ifconfig doesn't show any wireless network like wlan0 or ath0 or something like that. I see two wired connections: eth0 and eth1. What is the output of this command?
Code:

lsmod |grep ipw
jdk

Repet 08-14-2011 02:09 AM

I appreciate your help your post have helped me in the passed. I am glad that I joined.
Here is that output.
root@debian:/home/bo# lsmod | grep ipw
ipw2200 108264 0
libipw 18403 1 ipw2200
lib80211 2834 2 ipw2200,libipw


My wlan is on eth1.
The firs dmesg is for showing the driver used. Sometimes when a fault occurs the firmware is reported to be the culprit.
The second ifconfig is for showing what is configured by dhcp. eth1 is configured and working internally but ca not connect with router.
I there connect a wire cable to the ports of the router and though that line I get connected.

What can make the router loose the wifi totally? The win-box also lost connection?

jdkaye 08-14-2011 03:46 AM

Ok, it looks like the correct driver is installed. For my ZyXEL wifi dongle I had to install the zd1211rw firmware package for it to work at all. I don't think you have a firmware issue.
I don't understand why you are getting an inet address for eth0? You get in ip of 192.168.1.80 for eth0 and 192.168.1.168 for eth1. Do you have some cable plugged in while you're trying to use your wifi. You seem to be getting network traffic off both eth0 and eth1. I don't really understand your setup at all. Sorry. My ifconfig output looks like this:
Code:

OK

This is how you see what you see. wifi is configured on eth1. Cable tp/rj45 is on eth0. First I loos connection on eth1 but it looks as if I am online still! However I can not connect to either my router or the internet! But i can ping my own eth1 IP. I then, this time around, without doing any thing else connect a physical cable to my eth0 built in network interface. It talks to the router and receives an IP address. I get online.
The main question here is why does my routers wifi interface get smashed by my wifi so it goes down? If that is the case. What ever problem I have on my laptop somehow destroys the router wifi so that a windows box also looses connection. So I will next time the problem occurs only reboot the router. This said I want to point out that more people than I have experienced similar problems with their intel pro ipw2200 driver firmware combinations.
Strangely I have had this problem for a period of time only. I wounder if the problem perhaps is coming from the internet, is that a possibility?

jdkaye 08-15-2011 02:25 AM

Have you tried running your router with only the wifi connection and no wired connection. If you always have both eth0 and eth1 connected maybe that confuses your router. Maybe unplugging the cable or giving the command
Code:

sudo ifconfig eth0 down
. If the problem were the internet why would you be the only one affected? I can't understand why you would want both cable and wifi going at the same time.

Repet 08-15-2011 03:52 AM

You are wright it might be confusing to a router. I connect eth0/rj45 only after I lost wifi to see what the router would do. Under normal circumstances I only have wifi out of convenience.
So when the problem occurs I am only using wifi. When I lose wifi connection simultaneously on both winbox and my debian6 i walk up to the router with my laptop and connects it through rj45 and I get online thorough the rj45/eth0.
Previously when I have been behind a VPN only MY laptop have been affected. I find this strange! I disconnected my laptop from the VPN to minimize the number of possible culprits. When I did the router seams to have acquired a problem. It was by chance that a winbox was online at that time. So what can cause this?

/bo

jdkaye 08-15-2011 04:18 AM

Ok Repet. Your setup is clearly well beyond my experience. I have no knowledge of Windows and what it may or may not do. I installed vpn out of curiosity but haven't got around to configuring it yet. Maybe someone more experienced in these things can help. I hope so.
