I just completed installing kubuntu so i thought I'd try out the internet through the browser it came with. However, I cant seem to get it to work. The browser opens up but when I try to go somewhere it gives me an error message. how should I go about fixing this?
I have an AM2 socket MOBO with an athlon 64 x2 cpu @ 2.1 ghz, 2 gigs ddr 800, and a tp-link wireless adapter card.

Wireless cards can be tricky. What's the model number of the card?

TP-Link TL-WN651G Wireless G Network Adapter - 108Mbps, 802.11g, PCI

according to the people in the ubuntu forums it should work out of the box. my laptop has a card with an atheros chipset and it works fine for me. what error are you getting? there should be an icon that looks similar to a wireless tower or signal grouping in what you formerly knew as your taskbar that you can right click and get a load of information from. check that out. also ubuntuforums.org freakin rocks for any specific question such as this - i.e. how do i get this (specific) part working in ubuntu? - so you might want to try searching or posting there as well.
