I got this router and haven't set it up. I'm not sure if I really need it. i have an old Linksys Linksys WRT54GL router that still works. It seems a little slow at times, but mainly I use an ethernet cable to my PC. Wireless when my laptop is on (not too much) and gaming/streaming with my PS3. It seems to do the job well. Would there be major reasons why I should upgrade to the Apple or should I save the $$$$ ? Thanks for your thoughts.
