rtl8188ce in Debian Sid
 
Hey everyone there,> http://wiki.debian.org/rtl819x

My laptopn ships with a realtek 8188ce chipset.But It often
disconnects from my wireless router. I'm not sure whether it's the
problem of hardware(chipset) or the driver and firmware in Debian Sid.
I did reference this page** http://wiki.debian.org/rtl819x **. And it
did can connect to my router. The problem is it often disconnect from
my router. I was wondering someone use rtl8188ce fine with driver(in
Debian from Kernel) and firmware(in Debian from Realtek). If it's not
the problem of driver and firmware, I should go replace another
realtek 8188ce chipset.
Thanks in advance!
Regards

Was the wifi driver working stable before and stopped from doing (e.g.,
after an update) it or have you been always getting reconnects?

What kernel module are you loading ("lsmod | grep -i rtl")?

As you're on sid, you'll be running one of the latests kernels (3.2?) but
you can also try to compile kernel 3.3 (or even 3.4) available from
upstream sources to check if you get any improvement.

Also, there's a open bug report for the firmware blob (rtl8192cufw.bin),
is that the same file you're using? "dmesg | grep -i rtl" will tell:

Nope, it always behaves like this. I bought this laptop 2 months ago .
It sometimes
reconnects to my router, sometimes I have to reconnect manually.

I'm using 3.2.0-2-amd64 kernel.
hmm, I have Funtoo current installed in the same laptop, which use
kernel 3.2 and 3.3. Same problem.
One weird problem is If I don't use it in several minutes, it
disconnects from my router,and no longer reconnects an more.

I have seen this several times with Belkin routers. The issue is the
router not the card.
To test it reboot the router if you can then reconnect to it it is
most likely the router.

Mmm, then you can start with the usual tests (selecting a different
transmission channel -avoid restricted ones-, lowering the security -from
WPA2 to WPA, for instance) and watch for any improvement but I doubt
there is any :-(

By Googling around you'll find many reports for that card/chipset where
people complains for the same (random disconnects) and the solution tends
to be same in all cases: compile the realtek upstream driver instead using
the kernel stock one.

http://www.chayx.net/2011/06/how-to-install-realtek-rtl8188ce-wifi-drivers-thinkpad-edge-13-on-ubuntu-natty-1104.html

You can give it a try, and if that works for you... fine, but better if
you could report your findings either in Debian BTS or at linux wireless
mailing list so it gets fixed as soon as possible.

In addition to dmesg, review you "/var/log/messages". Kernel "oopes" and
traces use to be visible there :-)
