I was able to install but upon booting up after 5-10 sec the system runs extremely slow and locks up to the point where I have to hard reset... not sure what to do...

I tried a different .iso and tried on a disc and I was able to enter safe mod and go to root command line and run fix packages, everything seems to download and install correctly but once I get back to the desktop it freezes and hard lock up occurs again...

disabling my wireless seems to delay this from happening not sure why

Any advice on where to go from here?

I just wanted to say that Ubuntu is up and running but unfortunately my wireless is causing my hard lock ups. It is a Realtek 802.11 b/g/n Wireless LAN and I am not sure where to get drivers and I don't know how to enable my wired lan, other than that the system runs beautifully with compiz and cube desktop! – mark Aug 9 '12 at 14:05
I have found this… I have this network card in my laptop will try this fix when I get home and see what happens hopefully this is just a bad conflict with the drivers – mark Aug 9 '12 at 15:30

I just wanted to say that I have figured out the problem and it has been fixed! I have a realtek RTL8188CE 802.11b/g/n WiFi Adapter (rev 01).

I downloaded the Linux driver from their website and extracted the file then ran this commands:

sudo su

I navigate with cd to the uncompressed folder and ran:

sudo apt-get install build-essential
make install

And it worked--there have been no more lockups!
