ho un problema con la connessione wireless sul mio portatile Acer Extensa 5220.
La scheda e' una bcm4311
Codice: Seleziona tutto
04:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)
Subsystem: AMBIT Microsystem Corp. Unknown device 0422
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at f8000000 (32-bit, non-prefetchable) [size=16K]
Capabilities: [40] Power Management version 2
Capabilities: [58] Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable-
Capabilities: [d0] Express Legacy Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting <?>
Capabilities: [13c] Virtual Channel <?>
Kernel driver in use: b43-pci-bridge
Kernel modules: bcm43xx, ssb
La connessione la effettuo ad un ap Us robotics usrxx5462. Utilizzo WPA con pre shared key.
La connessione avviene, non mi pare ci siano problemi di configurazione. Il problema e' la stabilita' altalenante. Puo' capitare che la connessione rimanga stabile per giornate intere, dopo riavvii e spegnimenti cosi' come puo' succedere che per giorni la connessione continui a cadere. Ad esempio stamattina la connessione e' stata stabile sino alle 12 poi ha cominciato a cadere e la devo ripristinare (quando va bene) o devo chiudere, spegnere, riavviare, per riuscire a connettermi di nuovo (killall wpa_supplicant, rmmod b43, ecc.)
Il nb monta vista e le rare volte in cui lo uso questo problema non si verifica. Saltuariamente ho usato anche altri AP ma non sufficientemente a lungo per sapere che il problema sia la coppia bcm4311 usr5462. Altri dispositivi che ho usato si connettono al mio ap tranquillamente e stabilmente.
Qualche suggerimento?
grazie
