12.10 x64 - Lenovo E420s - RTL8188CE - Slow/Unstable Connection

Hey Kurt,

Thanks for all the help sir!
Not sure how to explain this one but now everything works. The only I did was give my laptop to my friend and all he did was literally:

modprobe rtl8192ce
iwconfig wlan0

He was just trying to load it for trouble shooting purposes but it took. As soon as he hit enter on iwconfig, it connected.

I removed the module from the blacklist and everything works through reboots.
Not really sure how to explain this one, but I'm guessing I should just take it as a win.

Again, thanks for the help. Really diggin' the support here

Hey kurt,

I tried blacklisting the module, rebooting, then installing the Realtek driver, then rebooting again. However, this time the wifi card does not come up at all. Also, when i run lspci -nnk | grep -iA2, it shows that the rtl8192ce driver is still in use.

Here is the output of lspci -nnk | grep -iA2

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)
	Subsystem: Realtek Semiconductor Co., Ltd. Device [10ec:8195]
	Kernel driver in use: rtl8192ce

I was able to get the card online by loading the module. After that, I did notice that the card would connect but just briefly before disconnecting:

Any other suggestions?

Thanks!

From where did you get the realtek drivers? They are not available for kernel 3.5 from the realtek site

I tried the same thing, but I get the below error when i try to modprobe

root@venki-ws003:/home/venkatesh/Downloads/rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012# modprobe rtl8192ce
FATAL: Error inserting rtl8192ce (/lib/modules/3.5.0-21-generic/kernel/drivers/net/wireless/rtlwifi/rtl8192ce/rtl8192ce.ko): Invalid argument

I installed the driver 92ce_linux_mac80211_0007.0809.2012.tar.gz from the realtek website, I am running ubuntu 12.10. Now my wireless card is not even detected.
