The iPod Touch only supports 802.11b and 802.11g wireless. There'd be no benefit in an "N" router if it's only being bought for the iPod.
If you're planning to eventually use other wifi devices such as laptops, then a "N" router might come in handy in the future. However, when even a single "G" or earlier device coexists with "N" devices, the overall throughput for all devices on the network will degrade somwehat.
Hey, thanks for thr replies.
Do you mean, when a G and N device are used at the same time, it will degrade the speed?
Thanks
Yes. The slowest device sets the speed of the network.
The G device will be its normal speed but the N device will drop to G speeds.
That explains it perfectly!
Thanks for all the replies.
