[Bug 902557] Re: 10ec:8176 Wireless not working in 12.04 for rtl8192ce (RTL8188CE)

 

I see that link is leads to the same attachment you uploaded on your
last post.


I am no expert but here is my two cents from looking through that capture.

I'm seeing only one "Deauthentication / Reassociation.   At frame 8418
you see the first deauthentication message from your laptop. There are a
lot of Logical Link Control frames being sent but that should be normal.

FHSS = 802.11b / OFDM = 802.11g
The thing that I keep seeing is your AP is using FHSS almost exclusively and only a couple frames from it to your laptop use OFDM modulation. I do see on a couple frames that your laptop uses FHSS. The deauthentication frames were the only I noticed.

I was wondering if those nodes are going to look the same on a kernel
that has a stable WLAN connection. Meaning If not too much trouble, use
an old kernel and grab another capture from a kernel that doesn't
deauthenticate all the time. Then see if the AP and laptop are
communicating at the same modulation.


As for me. 

uptime with kernel 3.8.0-29-generic is 18:55:52

dmesg | grep reason  (shows nothing)
dmesg | grep deauthen  (shows nothing)

My connection is stable.

The only thing that has changed in the last year was I got booted from
my old DSL and had to sign up for att u-verse dsl. This newer DSL locks
your modems mac in as your user login credentials so you can't replace
it with another one from newegg, amazon, best buy, etc.. The only way to
get one is from att and then go through the registration process which
locks your mac as you. You can buy them on ebay but I don't think I
would do that because they don't always authenticate to att's service.

Anyway, I got this new modem/router (motorola nvg510) last month. all
the newer kernels are working with my laptop / AP now. Call it a
coincidence, call it dumb luck, who knows but I know it is working great
now and the only thing I changed was the AP. Although I have installed
updated from lubuntu via apt-get update / apt-get upgrade / apt-get
dist-upgrade.

I even ran the fedora 19 lxde live iso and had no problems on that as
well.

Status in “linux” package in Ubuntu:

Status in “linux” source package in Precise:
  Confirmed

Bug description:
  Wireless no longer seems to work since I upgraded to Precise, it was working (albeit very flaky) ion 11.10, but it never seems to be able to connect to any access points since the upgrade.
  It can see all the available networks, but it can't seem to connect to any of them.
