RE: XPS13 ubuntu wireless issues.

I commented on this thread in July, and today I have at last got rid of my wireless issues on my XPS 13.

The solution - I replaced Ubuntu 13.10 with Windows 8.1 and discovered that this did NOT solve the problem. So I spent countless hours on the phone to Dell support over a week and yesterday they sent out an engineer to replace my wireless card. Wirless issues are now gone.

Over the last 4 months I came to realise that the wireless card dropped its connection around the same time that the fan started up. Others with a Windows OS have reported the same pattern on the XPS 13, suggesting there's an over-heating issue. That's not totally conclusive, but there was clearly a connection in my case.

All this time I thought my wireless issue was Ubuntu related...in my case it turns out it was a faulty wireless card.

RE: XPS13 ubuntu wireless issues.

Thanks mate. You made my day. I had the same problems than described in this thread.

I had not tried any other solution yet, preferring to leave it vanilla and call the Dell support. They replaced the whole hardware without actually asking a lot of questions nor doing any diagnosis. But the problem persisted ....

I then applied your solution and did not face any dependency issues and it completely fixed the Wifi problem.

So thanks again.

RE: XPS13 ubuntu wireless issues.

I still have the same problems, so the fix at

https://dev.uabgrid.uab.edu/wiki/ExperiencesWithSputnik#WirelessIssues

did not fix it.

I still have this damn delays when using ssh.

I will have to call dell and tell them about this forum. I hope I am able to get it working asap, this is totally frustrating.

RE: XPS13 ubuntu wireless issues.

I also had issues with slow ssh over wireless. Not on a Dell though.

What solved it for me was adding/modifying the following line in /etc/ssh/ssh_config

GSSAPIAuthentication no
Hope it helps.

Thanks Jaar, I just tried that, but it makes no difference.

Thank you anyway.

RE: XPS13 ubuntu wireless issues.

It is definitely the wireless connection. I have managed to connect through usb tethering using my mobile phone (that is connected to the same wifi) and the ssh works at normal speed (no perceptible delays).

Also browsing the internet is all of a sudden very fast (as expected).

Let's see what Dell tells me.

Thanks, regards

RE: XPS13 ubuntu wireless issues.

Hi,

I have good news from Dell. Surprisingly, the support person was aware of the problem and told me a direct answer that fixed it.

If you have 12.04, then:

go to http://wireless.kernel.org/en/users/Download/stable

and download compat-wireless version 3.6.8-1 (http://www.orbit-lab.org/kernel/compat-wireless-3-stable/v3.6/compat-wireless-3.6.8-1.tar.bz2)

You have to install build-essential and linux-headers-generic first

sudo apt-get install build-essential linux-headers-generic

Then follow the installation steps.

In my case I had to unzip it, then

./scripts/select-driver ath9k
make
sudo make install
sudo make unload 

Then reboot.

My wifi now is stable and ssh goes at normal speed!!!!

I tried to apply that patch to my 13.04 version but it did not compile properly, so I couldn't.

Anyway, I have a working version, I will remove 13.04.

Hope it helps anybody else, regards.

RE: XPS13 ubuntu wireless issues.

Cheiff, this is excellent thank you sir. 

Applied the changes to mine this morning and is now working like a dream. Finally feel like I have the great little machine I thought I was getting originally. 

Noticed a slight typo above. The select-driver script. It was actually named driver-select in the package I got. 

Thanks!

RE: XPS13 ubuntu wireless issues.

Has anyone tried the new Haskell based xps13 DE that have the Intel 7260 ac + bluetooth 4.0 card?  I've opened a ticket about my wireless issues with dell (I have the Advanced-N 6235) and they've completely ignored the ticket.  Everyday without fail I get errors about not being able to flush tx queues, I've tried all the fixes (linux compat, mainline kernel, etc.  Note I do not consider disabling 802.11n a fix).  Anyhow, at this point I'm ready to just replace my card with something that hopefully doesn't suck, and I want bluetooth 4.0 LE so I'm looking at buying the same mini pcie card the latest xps13 DE has.  Thanks for any feedback.

RE: XPS13 ubuntu wireless issues.

Hi,

Cheiff's solution fixed my problems too, but they came back with a vengeance a few days ago, now it won't connect at all, or rather it connects, but there is no internet connection, and the the connection drops. The only thing I can think of that happened in the mean time was a regular system update. Any ideas?
