reinstalling 10.5 with voiceover?

[UCLA Bruins Fan]

Hi Everyone,
My computer has been having some problems finding my wireless network,  
and apple suggested that I reinstall OS 10 to see if this corrects the  
problems (we know it's not a problem with the airport router itself  
because other computers on the network can talk to the base station  
with no problem) Apart from this little glitch te computer is running  
with no problems, but apple still suggested installing leopard again  
after walking me through the basic things that could be wrong to no  
avail.  My question is, can I install leopard indipendently with  
Voiceover, or will I need some sighted help?
I have been really pleased with apple's technical support as I try to  
figure out this issue, they have been helpful, they even dispatched a  
tech to take a look at the problem...  If reinstalling the operating  
system doesn't work, I will take my computer to the local apple store  
and see if I've got a hard drive issue.
Thanks for any help or suggestions anyone can give me! If you have any  
tips on reinstalling OS 10 please feel free to share!
