Speed Analysis

I found this a bit odd and wanted to see if others any any ideas.
Now i know that a comp can only perform so much. If you have a connection speed higher then the comps top performance then the extra rly doesnt matter. - I have two sets of speed tests. Both on the same speed test sites, pinged off the same location, done on the same laptop. The difference is the provider. One is verizon fios 50/50 and the other comcast 150/10. What actually caught my eye was the difference between the wired (ethernet cable) vs the wireless.

Verizon Wireless

Comcast Wireless
Comcast Wired
Verizon
Wired: 16.97/10.24 Wireless: 8.59/17.92

Comcast
Wired: 92.82/12.17 Wireless: 0.78/7.21

The wireless portion of comcast was what caught my eye at around a 0.8Mbps
