![]() ![]() ![]() 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". In Intel's WiFi Connection Utility, Hardware Radio Switch is directly related to W_DISABLE and pin 20.I have recently revived an old Sony Vaio VGN-N230E laptop of mine, and installed Linux Mint on it: ~ $ lsb_release -irc According the PCI Express Specification,, pin 20 (and now 51) are the W_DISABLE (wireless disable signal). ![]() Here's a picture of the mini/micro PCIe half height Broadcom BCM943142HM I pulled out of the laptop with pin 20 highlighted for reference. by blocking out pin 20 on the network adapters PCIe Micro interface as others have done to get their wireless adapter working after failed wireless switches or replacing wireless adapters cause these radio switch off predicaments. ![]() So, I did the next best thing - smashed it to PIECES!!! Okay, maybe I didn't, but I sure felt like my $6 part should work!Īnd, I made it work. This laptop doesn't have a radio switch or FN key to enable/disable the wireless any where. I opened the Intel WiFi Connection Utility and tried to enable the network adapter, but I kept getting an error about my "Hardware Radio Switch" was turned off. After I put the laptop back together and loaded the Intel drivers, I noticed it didn't find any nearby networks. ![]()
