I'm on a fresh install of Linux Mint 17.2. Since I've installed I've noticed my WiFi connection drops but doesn't disconnect. The WiFi works fine on Windows. I'm unable to ping any server or load any site for the duration. It seems to happen at random intervals.

So far I've ignored IPv6 to no avail. I also caught a bit of someone with the same problem who had a Realtek card. He was instructed to write the following in /etc/modprobe.d/
with a filename matching his Realtek card, I think. I did something similar:
nanor@teabags ~ $ cat /etc/modprobe.d/rtl8192ce.conf
options rtl8192ce fwlps=N ips=N
I've restarted and this doesn't seem to make any difference. Any help is greatly appreciated!
Based on
– kenorb – 2015-09-30T22:25:40.873SError: { CommWake DevExch }
, it seems you've some hard-disk issues, see: Mysterious Hard Disk Failure?. So probably you need to change your HDD (could be its driver), or it conflict with the other device.I've seen this happen before on an Intel vPro laptop, but only when the lid was closed. The problem eventually fixed itself (I think?). – jdrch – 2015-10-01T00:17:33.453
@Nanor Try: Fluctuating wifi signal and random disconnects rtl8192ce.
– kenorb – 2015-10-06T13:25:44.0301Try also post more info, as your logs doesn't contain info when it's actually dropped. The log which you included is only during the boot time. – kenorb – 2015-10-06T13:27:13.077
@Nanor Try changing your router to
– kenorb – 2015-10-06T13:28:44.850802.11bg
only. See also: Wifi Drops and Reconnects with UBUNTU 14.04 (Realtek RTL8188).@Nanor Try also the following settings instead:
options rtl8192ce ips=0 fwlps=0
. – kenorb – 2015-10-06T13:29:44.830@kenorb I'm unable to change the router to
bg
either through the router's control panel on192.168.0.1
or through terminal withsudo iwconfig wlan0 modu 11g
.What do I do with the new options you've tried? I've entered
modprobe rtl8192c-common
into terminal. Is that it? – Nanor – 2015-10-06T13:32:47.497@Nanor Edit
/etc/modprobe.d/rtl8192ce.conf
and change the options which you've pasted into these one, but actually these looks pretty the same (assumingN
=0
). – kenorb – 2015-10-06T13:39:49.487I'm afraid it still isn't working! – Nanor – 2015-10-08T15:34:37.563
