 |
|
Ciao a tutti, ho un problema con la la connessione wireless ad internet, spesso salta ed è notevolmente più lenta di quella tramite cavo ethernet nonostante sia a due metri dal router, e non riesco a capirne il motivo.
Ho cercato in rete ma non ho trovato persone con lo stesso problema, ho trovato solo persone a cui per qualche motivo la connessione non funziona proprio, vi posto i file di configurazione:
Scheda wireless:
30:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 02)
/etc/conf.d/net
config_wlan0=( "192.168.2.156 netmask 255.255.255.0 broadcast 192.168.2.255" )
routes_wlan0=( "default gw 192.168.2.1" )
modules=( "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext"
wpa_supplicant_wlan0="-Dwext -c /etc/wpa_supplicant/wpa_supplicant.conf"
/etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=100
ap_scan=2
update_config=1
network={
ssid="MY_SID"
scan_ssid=1
psk="xxx"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
priority=5
}
network={
ssid="MY_SID"
psk="xxx"
proto=RSN
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP WEP104 WEP40
}
Il driver è installato correttamente:
# ndiswrapper -l
bcmwl5 : driver installed
device (14E4:4312) present (alternate driver: bcm43xx)

allora, se ho capito bene puoi provare a usare fwcutter con i drivers windows invece di ndiswrapper
Da gentoo wiki:

As of version 2.6.21, broadcom wifi support appears to be reasonably stable by default (that is, udevd will load all needed modules automatically and everything will work out of the box). WPA, WPA2 and WEP are supported, though speed seems a little low (I'm getting 24Mb/s with bcm43xx vs. 50Mb/s with ndiswrapper; on the other hand, all kind of issues affecting ndiswrapper lately make it a worse choice).
Custom firmware should be obtained for bcm43xx driver to work. The simplest way to do this is to "emerge bcm43xx-fwcutter" and run it over the windows driver ("bcm43xx-fwcutter BCMWL564.SYS"). This will create a bunch of *.fw files that should be put into "/lib/firmware".
There is an irc channel on freenode.net called #bcm-users which you may get help regarding the above drivers.
The specification of txpower in BCM 4318 is different from the other bcm43xx cards. The actual implementation in bcm43xx.ko makes the txpower too weak to overcome obstacles, then you need to be close the access point to get a connection. Reference: https://forums.gentoo.org/viewtopic-p-3533332-highlight-4318.html#3533332 (this is not fully resolved in the 2.6.21, but has got much better).
The Acer "SignalUP" technology is actually nothing more than a specific antenna design. No additional software or drivers are required for it to work. |
questo è un lunghissimo post che affronta una serie di problemi con quella scheda:
