Cinnamon on DELL 7746 with wireless connection drop out

[petepluto]

Hi, I just got a DELL 7746 and I installed the Cinnamon edition. Desk is looking good. Thanks for the cool OS!

But now I face some problems:

The wireless connection drops out every now and then and I have to manually initiate the reconnection. But all my other devices on the table stay connected all the time.

Thanks

Please generate an overview of your system like this:
- launch a terminal window and make it fullscreen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

Thanks.

No strange things, only this: it's a very new machine.... Your hardware, including the wireless chipset, might run better on the 3.16.x kernel. Because then you have newer drivers. So first try that:
Update Manager - View - Linux kernels

After installation of the latest 3.16 kernel, reboot.

I installed 3.16. Now the trackpad is acting strange (coordinates are absolute) and the internet speed is so slow that it takes half a minute to load a page. Reverting to 3.13 ...

OK, then try installing all level 4 and 5 updates (not just the security ones, but all of them). Also install the latest kernel *within the 3.13 series*. Afterwards, reboot.

Thanks. But I cannot install kernels anymore:

Error: E: The method driver /usr/lib/apt/methods/http could not be found.

Thanks. But I cannot install kernels anymore:

Error: E: The method driver /usr/lib/apt/methods/http could not be found.

That's weird....

Some Google searching on this error suggests that the file "http" can be copied from another system, which should solve your problem.

So I've uploaded the file "http" from my own system, to my website. You can download it here:
https://sites.google.com/site/easylinux ... ects=0&d=1

After downloading it, simply leave it in the folder Downloads and execute this command:

Code: Select all

sudo cp -v ~/Downloads/http /usr/lib/apt/methods/

Then try again.

Thanks, now I get this when Iry to install the latest 3.13:

E: Method http has died unexpectedly!
E: Sub-process http returned an error code (100)
E: Method /usr/lib/apt/methods/http did not start correctly
