I have a Dell Inspiron 15 7559 dual-boot running Windows 10 and Linux Mint 18. Mint has been running smoothly for a few months now, but recently it started randomly kicking me off the wi-fi and then what I can only assume is disabling/disconnecting wireless completely. When this happens, I don't have the option to turn wireless back on using the graphical menu, and even
iwconfig shows my wireless isn't functioning.
ifconfig when wireless is functioning:
enp4s0 Link encap:Ethernet HWaddr f4:8e:38:e8:72:8d UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:301 errors:0 dropped:0 overruns:0 frame:0 TX packets:301 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1 RX bytes:42394 (42.3 KB) TX bytes:42394 (42.3 KB) wlp5s0 Link encap:Ethernet HWaddr ac:2b:6e:a2:71:be inet addr:172.27.223.183 Bcast:172.27.223.255 Mask:255.255.254.0 inet6 addr: fe80::ffc9:10ba:954b:335b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6057 errors:0 dropped:0 overruns:0 frame:0 TX packets:4330 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5329884 (5.3 MB) TX bytes:897294 (897.2 KB)
wlp5s0 is the wireless device. When Mint kicks me off wi-fi, this is the response to
error fetching interface information: Device not found
What is the issue? Is Mint disabling my wireless card?
How can I stop this from happening?
Note: a restart of my computer usually fixes the problem until I turn it off again. Then, next time I turn it on, I have the problem all over again. A restart will fix it again. However, I can't just keep having to restart my computer. I've also tried disabling power management, but that hasn't helped at all.
