				What is the real difference between the DIR 655 A4 and B1 versions? Ill be getting my router on monday in the mail. I wanna learn all i can about it before it arrives. Is one verson wayyyyyy better then the other? Or is it really not a big difference?

Rev Bs only support IPv6. 
Are you sure? My ISP has IPv6 deploying but not fully supported, and it's working just fine for me.

				He meant Rev As support ipv4 only, Rev Bs support ipv4 and ipv6 too. I have a Rev B1 with 2.01B5 firmware, nothing to complain about.

				Ya I worded that wrong. Rev As only support up to IPv4. Rev B's support IPv6 as well and FW updating Rev B for IPv6 was v2.03 I believe. Rev As are good routers as well. There most current FW is v1.35 and will not be supporting IPv6. If you want IPv6 or want it for future use, I recommend getting the Rev B version of the 655.
