Why is my iPod Touch so slow on Verizon midi 4620L?

I just got a Verizon mifi 4620L Jetpack hotspot thingy.

I connect my MacBook Pro to it and get 17mbps or so download speeds, 3mbps or so going up.

I connect my 3rd gen iPad to it and get about the same.

But when I connect my 5th gen iPod Touch to it I rarely get download speed peaks higher than 2mbps and most of the time the avg comes out to be less than 1mbps according to the Speedtest.net app on the iOS devices.

So, the iPad and MacBook Pro both work properly on the Verizon mifi hotspot and the iPod Touch doesn't. On all other networks I've tried the iPod Touch can support download speeds up to about 25mbps maybe even more. All these devices currently perform the same at home on the Comcast fed wifi network: very fast download speeds on them all with modest upload speeds. So I know there's nothing wrong with the iPod's wifi radios. There's just something quirky going on in how the iPod Touch and the Verizon mifi thing talk to one another because another thing that's strange: the iPod will download around 1mbps but then go up at about 10-12mbps. The exact opposite of what I would like except for those rare times I would actally like to send out a lot of photos quickly.

Does anyone know what might cause this?

Also, when I look at the connected devices as an admin the iPad's device name is recognized and listed but the iPod Touch remains named Unknown. Does this matter?

I'm frustrated because the iPod Touch is what I would most like to use with the mifi!

Any body come across this situation?
