Im going to set up a wireless network at my house using a N wireless router, and we already have high-speed cable internet coming in. BUT my desktop is slightly outdated. We only have 512 MB or ram, and only a 2.10 GHZ XP processor. To be perfectly honest, the only thing Im going to be using the wireless internet for is playing my Nintendo DS with my friends online. So when I play online, will it slow down my desktop really bad? Do you think I should upgrade before I install my router?? Any tips on this would be helpfull. Im not too savy on wireless internet.
