WiFi keeps disconnecting in 17.2 Cinnamon fresh install

[taninamdar]

Although this seems a common problem for Linux Mint 17.*, I have tried a couple of solutions posted in this forum, and none of them has worked for me so far.

The problem is probably well-known, the WiFi connection is very unstable, it gets disconnected after a short time. The connection is stable when I connect my laptop to the router using ethernet, or when I connect my laptop by WiFi in windows.

I will post outputs of any commands that you ask me to.

Thanks!

Try to disable power save wireless module options this way

Code: Select all

echo "options rtl8188ee fwlps=0 ips=0" | sudo tee /etc/modprobe.d/rtl8188ee.conf
sudo update-initramfs -u

Reboot to complete.

I have been having the same issue. WiFi is set to power save disabled. Here is the results of running inxi -Fxz:

I ran the code to make sure the power save was disabled. Here are the results:

~ $ echo "options rtl8188ee fwlps=0 ips=0" | sudo tee /etc/modprobe.d/rtl8188ee.conf
options rtl8188ee fwlps=0 ips=0

~ $ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-3.13.0-24-generic
Warning: No support for locale: en_US.utf8

I have also removed the internal WiFi card and used a USB WiFi with the same issue.

Thanks in advance.

Tried, but no luck.

Card-2: Realtek RTL8188CE 802.11b/g/n WiFi Adapter driver: rtl8192ce

@dmccotter, your card use rtl8192ce driver, to disable wireless power save use

Code: Select all

echo "options rtl8192ce fwlps=0 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo update-initramfs -u

@dmccotter, you should also try to ugpgrade your kernel to 3.16 series

Code: Select all

sudo apt install linux-kernel-generic

Reboot. Hope this helps.

[dmccotter]

@Laurent85, I have ugpgrade kernel to 3.16 series. I'll let you know what happens...Thanks

[dmccotter]

WiFi Stayed connected all night. Thanks for the fix.

I tried the same thing and it doesn't work. Any help?

Strange since your card is supported, see http://www.ubuntu.com/certification/cat ... 0ec%3A8179
Can you post back command results

Code: Select all

rfkill list all

Hello, anyone? My laptop is unusable without wifi!

[JeremyB]

Check the wifi encryption settings on the router, choose WPA2-AES, WPA2-PSK, or WPA2 only without WEP or TKIP

There's no point because same encryption works on my laptop in windows.

[JeremyB]

Everything works in Windows, TKIP is known to cause issues in Linux

I wonder how many times Chili555 has posted this info http://ubuntuforums.org/showthread.php? ... st13092185

OP:

Card-2: Realtek RTL8188EE Wireless Network Adapter driver: rtl8188ee port: 5000 bus-ID: 08:00.0

I recently got one of these USB Wifi adapters, and it wouldn't work (included installation process failed, horrible instructions, etc):

Code: Select all

Card-2: Edimax EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS] driver: rtl8192cu usb-ID: 7392:7811

I'm not sure about rtl8188ee vs rtl8192cu (or why my driver is rtl8192cu for an RTL8188CUS...) but if all else fails, you might look at
http://askubuntu.com/questions/246236/c ... 2cu-driver

(Link has some slight diffs from what I used, below - USB gizmo works fine now):
