very slow internet on Peppermint (no longer solved?)
« on: September 27, 2014, 06:35:31 am »
Hey all,

I just installed Peppermint OS on my husband's netbook today. It is an Acer Aspire One D270-1375. It runs on the Intel Atom (sadly), has been upgraded to 2 GB RAM and has 320 GB HDD.

I decided to install Peppermint given how ridiculously bogged down it was with Windows. I figured Peppermint OS would be a great way to lighten it up.

Unfortunately, it's just not working for me yet. It always shows internet connectivity, but the internet does not consistently pull up in either Chromium or elsewhere.

I've already installed the proprietary Broadcom driver.

I have run sudo apt-get update, but I get a lot of error messages. Unfortunately, I cannot show them, because I am having to send this from my computer, but here's an example:

Err http://th.archive.ubuntu.com trusty Release.gpg
Could not resolve 'th.archive.ubuntu.com'

I've run sudo apt-get upgrade (I suppose, it's only limitedly useful given that update doesn't run), and it takes an excruciatingly long time--also with some error messages (right now, I'm stuck on my last effort at the update, so I can't tell you the exact wording).

When I've quit trying, there are moments when the internet works, and Peppermint is as snappy as I hoped. It just comes and goes. Thoughts anyone?

If not yet obvious yet, I'm quite new to Linux in general, so I may be overlooking the obvious.

[Also, our internet connection is quite strong otherwise. Even on Windows 7, he had no problem with that, and I currently have no problem on my computer (running on Elementary OS).]

Can you open a terminal and post the output from this command:
Code: [Select]
sudo lshw -C network

Remember, Linux commands ARE case sensitive, so that's a capital C

Sure, how do I take screen shots in Peppermint? The computer is currently not accessing the internet, so I can't copy and paste the output, but if I have an image, I'll use a USB to transfer it to a computer with internet.

I don't see a way to do a screen shot, so I'm going to type it out and try to be careful that there are no typos.

Can you post the output from:
Code: [Select]
lspci -nn | grep -i 14e4:

I only really need the bit that looks like

[14e4:xxxx]

What is the symbol between the "-nn" and the "grep" and how do I reproduce it (without copy/paste)?

Okay, it says [14e4:4727]

Thanks, by the way, for being patient with me! I really appreciate it.

Okey dokey .. this device should work out of the box with the brcmsmac/bcma drivers (which are contained in the kernel).

What happens if you run:
Code: [Select]
sudo modprobe -r wl
then
Code: [Select]
sudo modprobe brcmsmac
?

I'm expecting wireless to die after the first command .. and come back to life after the second



FYI - If necessary, a reboot will get you back to where you are now

Okay, interesting... the first command killed it as you expected. The second command, however, caused it to start "thinking" (as in, the dreaded little circling spinning forever on end where the wifi signal ought to be shown) only to still end with telling me I am disconnected. Now, there is no internet connection whatsoever.

OK, try this:
run:
Code: [Select]
sudo gedit /etc/modprobe.d/blacklist.conf
and add these 3 NEW lines at the bottom
Code: [Select]
blacklist b43
blacklist ssb
blacklist wl
SAVE the file, and close gedit.

Back in the terminal run:
Code: [Select]
sudo gedit /etc/modules
and add a single NEW line at the bottom that reads
Code: [Select]
brcmsmac
SAVE the file and close gedit.

REBOOT.

Does wireless work after the reboot ?

Okay, I did as you said, but after the reboot, it returned to the spinning circle and finally letting me know it's disconnected.

It can still *see* all the wireless networks in the area, but it simply will not connect.

If it provides any clues, when I first loaded tried Peppermint out on the USB drive, I was quite impressed with its speed, and there were no connectivity issues. It was only after it installed that something went wrong.

Do you know your routers IP address ?

and do you know how to set a static IP in networkmanager ?

I do know my router's address, but I do not know how to set a static IP in networkmanager. Is there a tutorial I should read?

I'l walk you through it in a bit, but first let's try something...

run:
Code: [Select]
sudo gedit /etc/dhcp/dhclient.conf
and add a single new line at the bottom that reads:-
Code: [Select]
send vendor-class-indentifier "MSFT 5.0";
SAVE the file.

REBOOT.

Did wireless connect this time ?
