Poor Wireless Reception (Ubuntu 11.10)
Hello,
I recently purchased a Lenovo W520, which came with Windows 7 installed, and I created a dual-boot system with Ubuntu 11.10. The Lenovo W520 wireless card is a Real Tek 8188ce. I have great wireless reception in Windows 7. However, the reception in Ubuntu is very poor, basically unusable. The Unity/Gnome wireless reception icon shows the reception strength at two of the little waves, which means things load very, very slowly or not at all because the browser times out. As a result, I'm forced to use Windows 7, which makes me rather unhappy. Thinking that maybe Ubuntu didn't have the latest driver, since this is a new computer, I downloaded the latest Real Tek driver for Linux from Real Tek and installed it. I make sure Ubuntu was seeing the new driver, but it made no difference. I would think that maybe this Real Tek card is just crap, but it works great in Windows. Any ideas? Anyone else had this issue? I've searched around, but I can't find anyone who has quite this same problem. Thanks. |
Hello,
I would first check the signal level with following command (e.g.) Code:
iwlist wlan0 scan To check its name you can use the "iwconfig" command. All that has to be done as root, so type "sudo " before as you use Ubuntu. |
Thanks so much for the reply.
"iwlist wlan0 scan" outputs the following. The connection I'm using (my home wireless) is ESSID "2WIRE709": Quote:

Well I suppose that this:
Code:
Quality=34/70 Signal level=-76 dBm I don't know why you have that though but it seems that you are not alone, as shows a quick search in Google or linuxquestions' forums for "RealTek 8188ce", see http://www.linuxquestions.org/questi...archid=5090916. |
Well, good news! The latest Ubuntu 11.10 kernel upgrade seems to have solved the issue.
