Upgraded ubuntu to 13.10, I am using a Realtek wifi card on a minipc. The wifi connection goes slower than it should: speedtest gives me a 15mB/s download when on my phone it gets around 30 and the connection keeps dropping (signal level goes from 4 to 0 and I am asked wifi passw again and again).

This is the output of

lsmod | grep rtl

rtl8192ce             137725  0 
rtlwifi               110108  1 rtl8192ce
mac80211              596969  2 rtlwifi,rtl8192ce
cfg80211              479757  2 mac80211,rtlwifi

If i run iwconfig I get

wlan0     IEEE 802.11bgn  ESSID:"MYNETWORK"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: A4:B1:E9:6C:B0:B3

          Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
          Power Management:off
          Link Quality=46/70  Signal level=-64 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:4   Missed beacon:0

Any ideas?

Can you run uname -r to give us the kernel version. Do you have ethernet access to download packages? And are you on a 64 or 32 bit install? – Julian Stirling Dec 20 '13 at 12:00
3.11.0-14-generic I am on a 64 bit version – Stefano Vergani Dec 20 '13 at 12:02

There have been a lot of wifi problems with 13.10 with Kernel 3.11. This is often (not always) fixed by upgrading to 3.12. If you have wired internet download the new kernel:


Then run:

sudo dpkg -i linux-headers-3.12.0-*.deb linux-image-3.12.0-*.deb
sudo update-grub
sudo reboot

This should install the new kernel and then reboot.

user1703577 commented that they have tried this and it did not work. (In future please use comment rather than editing post) – Julian Stirling Dec 20 '13 at 14:34
Sorry, I didn't mean to edit the post, I did it by mistake – Stefano Vergani Dec 20 '13 at 14:39
No problem, sorry my idea didn't help. – Julian Stirling Dec 20 '13 at 15:00


test(hd0) badram(hd0) sleep 10 set net_default_server=(hd0),


set pxe_default_Server=hd0

and restart Ubuntu it should work fine.
