d6400 vs d6220

[Retired_Member]

apart their shapes and antennas, the speed 900vs1300, what are the worthy of note only differences between D6400 and D6200?
thanks

There are two USB ports on the D6400. Looks like just one on the D6220.

Where are you? Who is your ISP? There may be subtle differences in their support for your ISP's DSL. For example, some Netgear modems do not play nicely with the IPv6 implementation that BT uses in the UK.

thx...I dont use usb ports so much, so they're almost the same for me...ok.

I'm under "Telecom Italia" ISP with FTTC connection, but I don't know what's the dslam brand.
so? are they both good for my case?
