Ubuntu – Why is the internet so slow with an Atheros wireless card

After days of struggling with my connection speed, I finally decide I go down to the port level to investigate. Both my phone and ADSL were going via the same micro-filter. I had a spare phone port and micro-filter available therefore I have seperated the phone and ADSL to have their own independent telephone port, each connected through a micro-filter.

I then phone my provider to made a little fuss - now I am back to the super rocket speed again.

Thanks all for your support.

I do not know if this will work for you, but you may try and switch off power management for your wireless (it has helped others apparently). Open a terminal and type the following:

sudo iwconfig wlan0 power off  

Hit Enter. This is assuming that your wireless is labeled as wlan0. To check, in an open terminal simply type:

iwconfig  

It should list three things such as lo, wlan0 and eth0 although they may be labeled differently. Also, it would help if you could type in:

lspci  

This will allow us to ascertain what wireless chip you are using. If by switching off the power management works, then to make it permanent follow the instructions given by sagarchalise here:

How can I prevent iwconfig power management from being turned on?
