I'm sitting on the same level as my wireless router but still the internet is acting pretty slow.

Is there a way to "Flush" the connections on ubuntu and start over again? I think I've been noticing this problem eversince I came back from another country where I had to create a DSL wired connection to get access to the internet. Also, ever since then when I try to connect to ethernet (wired) It doesn't work.

Is there a way to get everything back to default.

This question came from our site for system and network administrators.

I had some severe issues with my Atheros based wireless card in my Acer laptop. It was fine in 10.10, but 11.04 was horrible. the command:

sudo -s

echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf

fixed it for me. Others have reported the same issue with the ATH9k driver
