weird half-disconnect

Good evening, ladies!

Since my old Wlan USB Stick broke I ordered a new one which should run on linux natively (TP-Link TL-WN321G with a Realtek rt73 chip (I think)).
Thats basically true - linux drivers are available and thanks to pacman quick installed.

At the moment I use the module 'rt73usb' which was installed with the package 'rt2x00-rt71w-fw' with wpa_supplicant.

But now and then it happens that my internet disconnects but not the Wlan itself (!) so I can still connect to the router (192.168.1.1) but not e.g. google.de/74.125.39.103.
After about 30 - 60 seconds the problem solves itself and the WWW is available again... I just have to wait.

Its important to say that the problem is not the network. Until I used the new Stick everything was ok.
During my disconnects other users in the network can't connect to my pc (with samba).

I know that the situation makes no sense but maybe you got an idea.

Re: weird half-disconnect

Sounds very odd. Next time it disconnects, try executing netstat -r to see if your default route is still there. That could prevent you from accessing the internet but would still allow you to ping things on your same subnet.

Re: weird half-disconnect

While disconnect

[raunz@fuckup ~]$ netstat -r
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.1.0     *               255.255.255.0   U         0 0          0 wlan0
# ~ 5 seconds later
default         192.168.1.1     0.0.0.0         UG        0 0          0 wlan0

When reconnected

[raunz@fuckup ~]$ netstat -r
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.1.0     *               255.255.255.0   U         0 0          0 wlan0
default         localhost       0.0.0.0         UG        0 0          0 wlan0

Looks about the same to me. ^^

/edit
My gateway should be 192.168.1.1 btw

Re: weird half-disconnect

Are using network manager or wicd?

Re: weird half-disconnect

Nope wpa_supplicant.

But I will test wicd for a while and see if it helps.

/edit
Test failed
Wicd or wpa_supplicant doesn't make a difference.
