[SunHELP] help: unix and comcast broadband

[Arthur Wouk]

 i have a sparc 2/10 local network (two of each) and i am planning to
get a broadband connection. dsl is out (qwest's service area come to
about a quarter mile of my house and stops). so i am left with my
cable provider comcast. i am told that their tech support people only
understand windows.  is there any place where i can find info on a 
connection from unix?

my daughter has a power mac g4 which will also be connected wirelessly
to the ethernet hub which i use. any clues as to how to make
everything work with comcast would be appreciated.

i have been using a dial-up connection via kermit to this point.
with the broadband i need to switch to a local browser, i assume. for a
sparc10 with either hypersparc 150 mhz or twin 75mhz supersparcs (i
have one of each) is there any preferred browser: opera or mozilla?
