WiFi dropping with realtek card on Linux Mint

3

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 SError: { 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 – 2015-10-06T13:25:44.030

1Try 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 802.11bg only. See also: Wifi Drops and Reconnects with UBUNTU 14.04 (Realtek RTL8188).

– kenorb – 2015-10-06T13:28:44.850

@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 on 192.168.0.1 or through terminal with sudo 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 (assuming N = 0). – kenorb – 2015-10-06T13:39:49.487

I'm afraid it still isn't working! – Nanor – 2015-10-08T15:34:37.563

You can use an, Linux compatible USB wireless adapters. This solved my problem on my old laptop. There are few brands that work great, here is a short list

TP-Link TL-WN722N 150Mbps High Gain Wireless USB Adapter

TRENDNET TEW 664UB

and there are more you can look on google for models.

Ideally I'd like to fix this rather than buy a new card but I fear I have no choice. – Nanor – 2015-10-13T12:13:38.830
