Network connection drops after 10 minutes or so

When it drops, run:

dmesg | tail -n 10 > ~/Desktop/output.txt; lsb_release -a >> ~/Desktop/output.txt

Thanks

obviously get reconnected and open the text file and give the text as an update

Thanks

mesg | tail -n 10 > ~/Desktop/output.txt; lsb_release -a >> ~/Desktop/output.txt

Did you install it with that PPA?

Install what with PPA? The system was working fine until a month ago. Linux was installed as a windows application in a dual boot configuration with wubi. I suspect that one of the updates broke it. I just do know which one.

The network connection seems to stay up after the fourth of fifth time the wireless service is stopped and restarted. When I shut down the system and restart I still have the same problem.

Add the PPA in the link:

sudo add-apt-repository ppa:lexical/hwe-wireless
sudo apt-get update
sudo apt-get install rtl8192ce-dkms

Should be ok

That did the trick thank you very much.

When someone gives you a link. Read it ALL.

I Spoke to soon.

 It is doing the same thing. This is a dual boot machine and the windows side works fine so that eliminates the hardware. It starts out dropping after 5 minutes. Stopping and restarting the connection extends the time a little more each time I do it.

I added a usb WIFI adapter in disabled the on board device. The same symptoms still exists. It looks like the problem is something other then the card drivers. I have used this additional device before without incident.

Tried disabling IPv6? Could help

IPV6 has been disabled. It still does the same thing. Connection drops ager 10 minutes.

Can you give the outut of:

sudo lshw -C network

Thanks

Not sure what I should be looking for in the above mentioned link. I installed a different usb wifi device from Hawking that has a different chip set. I have the same problem. After a while the connection drops. I have been running the system monitor and the communication in both directions drops to a few bytes out and in whenever I do a web page refresh. It does not seem to make a difference on what wifi device I am using. The system was running fine up till about three weeks ago. The problem started after update manager ran and installed a bunch of updates. I suspect this is not a driver problem but something else. I have tried to correlate the amount of data being sent and data being received to the time the system stops communicating but so far I have not seen anything consistent. Stopping and starting the connection clears the problem for a while but it always comes back.

Basically it's a known bug as far as I can tell. Have you tried a different wireless channel?

I have tried a different wireless channel and that did not help. Went to a different access point. That did not help.
Started booting with an older kernel. That did help. Having a wired connection also solves the problem. It looks like it is a kernel problem. Maybe it will go away in the the next kernel update. Until then I will use a kernel that is two reves back.

Make that 3 revs back. (.28)

The latest round of patches and kernel update solved the problem
