Chromebook NICs

I had a school call and say they had a HP Windows laptop sitting next to a HP Chromebook. The Chromebook was working fine at another school and all WLAN settings were exactly alike. Yet, when they moved the Chromebooks to another school they could only get 1 Mbps compared to the Windows laptop cranking 125 Mbps.

A quick check of the wall revealed a major dB loss. Also, some research showed the Chromebook only has a 5 GHz NIC. The Windows laptop also had a 2.4 GHz NIC. Adding an AP in the room resolved all issues.

Real world proof that a 5 GHz signal attenuates quickly and cannot penetrate walls as well as 2.4 GHz.
