RTL8188CE Wireless Card Issues

Postby inseighn on Wed Nov 14, 2012 1:31 pm

I just recently bought a laptop and the wireless card I have is the RTL8188CE. It requently drops signal and has terrible download rates and I was wondering what I could do to fix this issue? It works fine in W7(which was what was originally installed on the laptop) I have already tried download the latest drivers from the realtek website and install those and it has the same problem. Here is my mintwifi log:

Issues:
It will sometimes connect for about a minute, then drop the connection then reconnect a minute or two later if it connects at all.
When it is connected the speeds are terrible.
Signal rate is horrid even when right next to the router.

I've did a little research on my own and found nothing, so I remove the driver and reinstalled it(for about the 5th time) but this time I also did a complete uninstall of network-manager and installed Wicd instead and have found my connection to be more stable SO FAR.

I have a similar problem with the same card. Infuriating when a wired connection is not an option.

Seems to work for a random amount of time and then just locks up and stops passing traffic. If I disable the wireless connection and renable it again it works straight away. I've noted that when I run a "route" command in terminal when the connection is borked, it takes ages to return anything to the console.

I've tried installing the asus drivers but "make" fails

Linux Mint 14 Nadia

When it's working -

Re: RTL8188CE Wireless Card Issues

Postby arimbun on Fri Feb 01, 2013 7:49 am

Hi, I have the same issue here with Mint 14. Wireless speed is better on Windows (about 3 Mbps), although it's still far from the 9 Mbps that I am able to get from my iPhone 4 and Nexus 7.

In Mint 14, the speed is much worse (around 0.5 Mbps) and connection is very unstable. Upload speed is stable however (around 0.8 Mbps, which is faster than my download speed!). It also does not have a very good range.

The following mintWifi output is done on an Ethernet connection.

Re: RTL8188CE Wireless Card Issues

I also have a new laptop with the RTL8188CE and found the Wifi wouldn't work, and later found multiple problem symtoms in intalling Mint 14-Nadia. Not sure if I should have started a new thread, but here is what I found to solve problems several people report on the RTL8188CE chipset.

To summarize the story below, a new driver is required from the realtek web site.

The mintWifi command reports the same WiFi chip:
-- Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
==> PCI ID = 10ec:8176 (rev 01)

The Wifi worked fine with the 32 bit install DVD, but after a suspend, Wifi would not resume and the yellow WiFi light stayed off. The 64bit install DVD recognized connections, but WEP would not work (it kept asking for a password). At first I installed 32b mint, then found the Wifi didn't work at all (no wireless networks found), then worked OK after upgrading, except Wifi stopped working after resuming from a suspend (the yellow light stayed off).

I found rebooting and removing power seemed to reset something and Wifi worked in 64b (for a while), but then it seems to be a random problem and I reached a point where the WEP stopped working again, and sometimes the suspend/resume failed to restart.

I saw a similar problems on another web site, so went to http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true, searched for "RTL8188CE" and scrolled to the linux section. There is a new driver released Feb 7, 2013. After using "tar xjf linux_mac80211_0012.0207.2013.tar.bz2" to unpack, I checked the readme that say to install I needed to do "make" then "sudo make install" and reboot.

So far Wifi seems to work. The enable/disable Wifi from the bottom right toolbar turns the wifi light on/off, and WEP works OK even after a suspend (close laptop lid).

I have the rtl8188ce chipset working in Mint 16 Petra. The problem is the module has the firmware power saver enabled by default. To fix, add this to /etc/modprobe.d/rtl8192ce.conf:
Code: Select all
#disable power saving
options rtl8192ce ips=0

# WARNING! Do not enable this option (firmware device manager).
# It causes bugs.
options rtl8192ce fwlps=0

# Use software control instead
options rtl8192ce swlps=1


I found I did not need to download any drivers from Realtek, the ones included in Petra seem to work fine. Cheers

Re: RTL8188CE Wireless Card Issues

Postby ToddG on Tue Jan 07, 2014 3:48 am

Thought I'd put in my 2 cents on this.

I installed Mint 15 KDE on a Toshiba L75D-A7283, It has a realtek RTL8188EE wifi card in it according to the tag on the bottom of the laptop. Everything I used to check the card reported letters besides "EE" on the end. Wifi did not work after install.

I had to go to RealTek and download the drivers for it at
http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#RTL8188CE

When I tried to 'make' the binaries I got an error. One of the source files had an error(actually more of an omission) in it.
I found a solution on the ubuntu forum that worked. http://ubuntuforums.org/showthread.php?t=2146803
Once I edited pci.h, made the binaries and rebooted, the wifi was working.
