I hope someone can help me with this. I am new to Ubuntu and Linux and I'm trying to learn.
I have a Dell Inspiron 5160 laptop which is a dual boot between Windows XP and Ubuntu 8.04. The wireless card is a Dlink that uses the Atheros chipset. The info on the chipset (obtained via lspci -v) is as follows:
I installed Ubuntu via Wubi if that makes any difference.Ethernet controller: Atheros Communications Inc. AR5212/AR5213 Multiprotocol MAC/baseband processor (rev 01)
Subsystem: D-Link System Inc D-link DWL-G650 (Rev B3,B5) Wireless cardbus adapter
Flags: bus master, medium devsel, latency 168, IRQ 16
Memory at 68000000 (32-bit, non-prefetchable) [size=64K]
My system consists of a cable modem hooked to a Linksys WRT54G router running WEP encryption (yes I know not that secure). The IP addresses are obtained via DHCP.
For the first few days this system connected to internet fine in Ubuntu. This morning when I turned the machine on, I fired up the browser and nothing would connect. I also tried Pidgin and that would not connect either. Both were working fine last night. I then tried accessing some files on other machines in my local network and that DID work. I also rebooted into Windows and verified that the internet connection was working. It was.
I then went back into Ubuntu and tried pinging several sites from the terminal (Yahoo, Google, and a domain that I own) and they did ping fine.
I searched the forum but was unable to find anything that applied directly to my situation and the few things I saw that were similar did not help. Here is some more info that I obtained that I thought might be needed to diagnose my problem:

I should also mention that I am running NO firewall on the linux install at this time.
I apologize if I've "over-info'ed" or "under-info'ed" this post but I really am quite new to this. I am hopeful that someone can lead me in the right direction because I really don't know what I could have done to break this. It was working fine last night and the only thing I have been messing with is the fonts on the system.
