Can you place the output of the following terminal command here:

Code: Select all

inxi -nN

This will gives us more detailed info about your network card.

yeah for sure:
ken@ken-Studio-XPS-435T-9000 ~ $ inxi -nN
Network: Card-1: Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller driver: r8169
IF: eth0 state: down mac: 00:23:ae:e7:2b:30
Card-2: Realtek RTL8188CE 802.11b/g/n WiFi Adapter driver: rtl8192ce
IF: wlan0 state: up mac: c8:60:00:d3:f0:88

I have identical problem since Mint 9. The Power Management settings in Ubuntu is causing less power to be supplied to the wireless internet device there by constantly slowing down the internet speed in many wireless devices.

Open terminal and type:

Code: Select all

sudo iwconfig

Check wireless device name, usually it will be wlan0. Then type:

Code: Select all

sudo iwconfig wlan0 power off

It will switch off power mangement by Ubuntu for your wireless device. Now, try download youtube video!
To make this permanently, open as administrator /etc/pm/power.d or simply create that location.
Open gedit, save it as "wireless" on this location after adding following lines:

Code: Select all

#!/bin/sh

/sbin/iwconfig wlan0 power off

...and make it exectable:

Code: Select all

sudo chmod 755 /etc/pm/power.d/wireless.txt

Wireless connection information - speed setting:

1. - Right click on the wireless icon in the top right of the screen and choose "Connection Information".
the speed as 54Mb/s which is typical of an 802.11g/n network.

2. - If the speed is less than you expect and the network manager is showing a speed of less than 54Mbps then you can try forcing it to use 54Mbps using iwconfig (temporary solution!). First establish the name of the interface. This can be taken from the Connection Information panel in Network Manager. Change the setting dynamically using the following command:

Code: Select all

sudo iwconfig eth1 rate 54M

3. - Making the network speed changes permanent - a file "wireless-speed" should be created in location:
/etc/network/if-up.d (opel location as administrator). Contents should be as follows:

Code: Select all

#!/bin/sh -e
#
# Sets speed of interface to 54M

if [ "$IFACE" = "eth1" ] ; then
        iwconfig eth1 rate 54M
fi

...obviously changing the entries form eth1 as appropriate. The command should be made executable:

Code: Select all

sudo chmod 755 wireless-speed

The scripts in the /etc/network/if-up.d directory are all run whenever a network interface is brought up. The script checks to see if it is the interface in question and if so runs the iwconfig command that we ran earlier.

Having the same problem here with no fix yet.

Here's the output of: inxi -nN

And here is the output for: sudo iwconfig

eth0 no wireless extensions.

From what I can tell, the problems here are very similar. Power Managment is already off, i know that my connection (when it is running) is at its lowest 78 Mb/s. I also already contacted my internet provider and there should be no reason for this to happen. Also very new to Linux so if I've made some booboo please let me know.
