I have recently bought a HP Envy DV7-7201 which had Windows 8 on it. I installed Ubuntu 12.04 alongside it and everything was fine at home. I could access the internet through my wireless router (RTA10235WE) using Ubuntu.

I am visiting family for the holidays who have a Vodafone EasyBox wireless router. Windows 8 connects to the router fine. It uses WPA with TKIP encryption (802.11n).

However, Ubuntu detects the network but does not establish a connection. I can not ping or access the router (I can just fine in Windows).

After reading through lots of similar issues I couldn't solve the issue. Could someone please help me solve this? I would be so grateful. Here is some info others have asked for in similar threads.

Can you also post the output of lspci -nnk | grep -iA2 net - it should show the wireless card model. –  mikewhatever Dec 24 '12 at 4:58
    
There is no IP address there. Either it is provided from a DHCPserver, or you should set it manually in Linux, it depends on your settings. Please post your /etc/network/interfaces also! –  Doka Dec 24 '12 at 7:41
