I have try various brand of wireless router, Netgear, Buffalo etc. but always have problems connecting on the wireless. I have mix match of 5 computers, 2 Mac and 3 PCs. All of them running G, except for my MBP running N. It seems like my MBP is the only problem connecting to wireless sometimes. Should i get airport extreme base since i have mix match of Mac and PC? or can I down grade my N to G??
