Hi all. I am totally new to Ubuntu (obviously, or I wouldn't be in this forum, sorry) and have a couple of newbee qestions. First of all, a bit of background. I have a Compaq Presario Notebook computer, It's about 6 years old, has 512 Mb RAM, and uses Windows Vista Basic. I first tried Ubuntu installed on a USB Stick to just try it out before I totally committed to it. It was soooo slow that I was totally depressed. So I thought if I used the WUBI version and installed it with Windows that it might be a bit faster, so I tried that. It is still at least 10 times slower than my Windows Vista(which is terribly slow already). I was wondering if it would speed up faster than Windows Vista if I just jumped in totally and installed it completely? The reason I wanted to try Ubuntu in the first place was that I had heard that it was FASTER and more secure than Windows. If it isn't any faster, I probably won't go with it.
Also, I have another problem. At first Ubuntu would not recognize my wireless adapter. I looked around and found a cure for that by updating the driver for my adapter. Ok, now it recognizes my adapter, and I can find my wireless network in the list of networks available. The problem now though is that every 10 or 15 seconds it keeps asking for the authentication code for my network over and over again, and never signs on to my network. What can be done about this? Any help with either of these two problems would be greately appreciated.
