Network frozen

After installing OpenSuSE 13.1 my network gets frozen by few seconds. No matter with wireless card i used. I have one internal network card (build in my laptop) and usb network card.

Bus 001 Device 002: ID 079b:0062 Sagem XG-76NA 802.11bg


08:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01) 

Problem don’t occurs on OpenSuSE 12.3 .

Try to install the firmware package from here:
PackMan :: Informationen zum Paket b43-firmware

Or install the broadcom-wl driver, that should work in any case:
PackMan :: Informationen zum Paket broadcom-wl
You need the package broadcom-wl and one of the broadcom-wl-kmp-* packages depending on your kernel (most probably broadcom-wl-kmp-desktop).

Edit: for the Sagem USB card, you apparently need this:
This is included in the distribution so just install it in YaST or with:

sudo zypper in zd1211-firmware

LANG=C zypper search zd1211-firmware

Loading repository data...
Reading installed packages...

S | Name            | Summary                             | Type   
i | zd1211-firmware | Firmware for ZD1211 USB WLAN sticks | package

OK, so it is installed.
But it doesn’t work?

And have you tried with the broadcom-wl driver for the other one?
