Just talked to SBC to get their DSL and the rep said I need to have an ethernet port on my computer. My couple of years old Dell does not have that - only have couple of USB ports (probably 1.0). Is there a converter of some kind that I can buy to get around this? Would there be any issues if I use the other USB port with my mouse? I am not very familiar with these kind of connections and any help would be sincerely appreciated. Thank you.
