Not really.<p>As I always request in these threads, I&#x27;d like someone to point me to a peer-reviewed paper that shows 5GHz being attenuated more by building materials than 2.4GHz.<p>The usual culprit is that people put their 5GHz networks on the old &quot;low power channels&quot;, which nearly every router I&#x27;ve ever seen chooses by default.  Half the power, half the signal in the next room, of course.<p>Choose channel 149 which is full-power.
