[Resent after subscribing to the ML, sorry if that makes it twice] -- Hi, I am experiencing very poor network performance using the b34 module with a Broadcom BCM4306 revision 3 (the system is a Compaq HP R3000 laptop)
The download transfert rate goes from a few bytes to 20Kb/s at max
whereas it commonly reached 200Kb under Windows or on the other
laptops in the hose (using Intel chipset under Linux, for example).
The connection is so unstable that it's causing timeouts during wget
downloads, and makes that system under Linux basically umusable...
The problem is not exactly new and apparently been reported several
times on various forums (mostly Ubuntu) though the problem is not
distro specific (I switched from Ubuntu to Fedora, from x86_64 to i386
and the problem remains). I checked in the archives and found some
similar problems but no solution.
The connection is using basic WEP encryption, wpa_supplicant involved.
The router is a Netgear WGR614 v7.
