There is no advantage to 5ghz for your grill unless your router is outside in clear line of site to the grill.
5ghz is faster than 2.4ghz but why do you want higher speed to control your grill or check the status? Is one half of a second to change the temperature of your grill not fast enough...
Living in stormy south Florida, love the cover. Awesome that it fits so well.
Who wants a cover that lifts off and blows away in the slightest wind?
I've had custom covers for other grills that I've cussed and strapped and laid bricks on top to keep the damn thing from blowing away.
No...
