I’ve running QNX 6.2 with a SIS900 (Realtek based) network card. After starting
the OS, ping and telnet works fine. So I can assume that the network
ist properly configured.
But after starting a internet browser (e.g. Mozilla), the network stop
working. A simultanously running ping to a host stops at the moment
of the starting browser.
Does anyone have a clue what the problem might be?
I connect to the internet with an external DSL Router.
Ping and telnet to a external internet adress works fine.
I can ping to an external host such as www.yahoo.com.
But after starting a browser (Mozilla or the qnx Browser)
no network connection is furthermore possible. It’s also
impossible call a webpage with the browser.
Even if I close the browser there is no ping or telnet
possible.
I can open a window with an start a ping to www.yahoo.com.
The ping runs up to the moment when a browser is started.
After starting the browser the ping stops.
I tried to increase the ionet stacksize to 11648 but that dont
help.
I’d just like to mention that I sometimes have a problem similar to that, except it doesn’t happen as soon as I open the web browser, but after some time, around 10 - 30 minutes.
Also I’ve noticed that, at least for me, my CPU usage goes up to 100% and stays there until I close PhDialer sometimes while I’m online, but that probably doesn’t have much to do with that other problem as I’m on dial-up.
Hm, this getting confused…
So ping stopped when you start browser, and never recover?
Does ping return an error, or it just hang? Can you post output
of following command (after ping stopped).
pidin -Pio-net
ls /var/dumps
netstat -ni
netstat -nr
I got no error message from the ping after starting the browser.
the /var/dumps directory is also empty.
the pidin -Pio-net shows (after starting the browser):
pidin mem says:
devn-sis9.so @b8244000 48K 4096
its the sis900 at a elitegroup k7s5a mainboard. the nic is based on
a realtek chip.
and nicinfo give me no errors:

I am not nic driver expert but these difinitaly unhealthy.
The 0 Mac address, the wrong media rate …
Sounds like the driver didn’t agree with the hardware,
I am not sure if you could play the driver options or
maybe could use another driver. I would let some
hardware guy step in to judge that.
xtang,
Dear folks, obviously I habe exactly the same problem: Sis900 on board K5S7A, external ADSL-modem-router und net stops if I start a browser or e-amil-client. Is there any solution of that problem?
You have your onboard network chip missconfigured. Probably, you burnt new BIOS. Builder of your motherboard must have special utility to restore correct Ethernet number. Download and run it.
