Very slow download speeds with new 12.04 upgrade

**adglife** · August 8th, 2012

Hello Ubuntu world!

I am completely and utterly new, so stick with me here.

I have a desktop computer that I had Ubuntu 10.10 loaded on. Started it up after about a year and upgraded gradually to 12.04 LTS.

(I want to post specs, but how do I do it in the fancy scroll box?)

Anyway, I have noticed extremely slow internet speeds since day 1. I just got done reading a popular post about MTU and RMEM, etc., and have tried adjusting but I'm afraid I'm completely lost.

Currently purchasing a 1.5M connection (bottom of the totem pole), and average download speeds of .50M down.

Sometimes far, far less.

Noticed that interface in use is "lo" not "wlan0".

Help!

Your ping times are indeed a bit long. You might try a driver parameter:

Code:

sudo modprobe -r rt61pci
sudo modprobe rt61pci nohwcrypt=Y

Now check:

Code:

ping -c3 8.8.8.8

Any improvement?

How is your signal strength?

Code:

nm-tool

You might also try installing the Ubuntu version of compat-wireless:

Code:

sudo apt-get install linux-backports-modules-cw-3.3-precise-generic

You may need the pae version; check:

Code:

uname -r

If your kernel version is pae, then do:

Code:

sudo apt-get install linux-backports-modules-cw-3.3-precise-generic-pae

Reboot and let us hear your report.

I don't have any idea what you just had me do with my computer, but I'm up to exactly where I need to be. Seems to have worked. Can you dumb down what you did so that I can paint the picture in my head of the magic that just happened?

**chili555** · August 9th, 2012

The compat-wireless project aims to fine-tune and update drivers beyond the vanilla in-kernel version. Often, not always, a correction or improvement is included in compat-wireless. This package is an Ubuntu-ized version: linux-backports-modules-cw-3.3-precise-generic.

Or was it the driver parameter that fixed it?
