![]() ![]() Before using the wireless LAN, make sure your access point is on and operating. You can establish wireless LAN communications between your VAIO computer and an access point (not supplied) using VAIO Smart Network. Product: PRO/Wireless 3945ABG Network ConnectionĬapabilities: pm msi pciexpress bus_master cap_list ethernet physical wirelessĬonfiguration: broadcast=yes driver=iwl3945 driverversion=3.2.0-23-generic firmware=15.32.2.9 ip=192.168.15.4 latency=0 link=yes multicast=yes wireless=IEEE 802.Having read through the user manual for this model there is no mention of an external wireless switch, which is odd, but it does make mention of ‘Wireless Functions’ software switch within Vaio Smart Network – this is in addition to the Wireless LAN software switch. Product: 88E8036 PCI-E Fast Ethernet ControllerĬapabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiationĬonfiguration: autonegotiation=on broadcast=yes driver=sky2 driverversion=1.30 firmware=N/A latency=0 link=no multicast=yes port=twisted pair Perhaps this has some valuable information: ~ $ lshw -c network It is really frustrating to have to come back to the laptop, just to squeeze the wifi switch (harder) onto the ON position every couple of hours. Hopefully you guys have an idea how to solve this. Is it possible to bypass the hardware switch altogether? Unfortunately, the problem persists.ĭoing rm /etc/rfkill and rebooting does not work, as the wifi remains "hard blocked".ĭoing rfkill event, followed by rfkill unblock xxxxxxxxxx.xxxxxx (with the number shown by the previous command) does not work, either. RTNETLINK answers: Operation not possible due to RF-killĭoing lsmod | grep sony revealed that a module called sony_laptop was loaded, and so I proceeded to do echo "blacklist sony_laptop" > /etc/modprobe.d/nf and rebooted my computer. SIOCSIFFLAGS: Operation not possible due to RF-killĭoing ip link set wlan0 up also fails: ~ $ ifconfig wlan0 up (Note: I have not tried to "reset to factory defaults", as some other posts have suggested.)ĭoing rfkill unblock all does not work, as the wifi remains "hard blocked".ĭoing ifconfig wlan0 up fails with the following error message: ~ $ ifconfig wlan0 up This is particularly frustrating, seeing how I'm connecting to it remotely (SSH).Ĭhecking the BIOS for some sort of wlan/wifi setting. ![]() When that happens, rfkill displays the wifi as "hard blocked": ~ $ rfkill list As a consequence, the laptop will randomly/constantly switch its wifi off, even when physically idle (something to do with some spring, perhaps?). The laptop works just fine, except for one problem: it has a hardware wifi switch that is slightly "loose". I have recently revived an old Sony Vaio VGN-N230E laptop of mine, and installed Linux Mint on it: ~ $ lsb_release -irc ![]()
