Make 5GHz as default network on iPhone

Bob, he wants the 2.4 there as backup to the 5, that's why he's not happy having to delete the 2.4.

I'm sure when he's farther away from his router, the 5 isn't even showing up but the 2.4 still does, and this is how he gets stuck, once his phone has the 2.4 and even if he walks back right to the router, it will likely stay on the 2.4 (but OP wants it to switch back to 5).

If he deletes the 2.4 entirely, then he's now lost wifi in the further reachers where he likely has 2.4, but no 5, signal.

No, iOS devices are great for picking up networks not the best at letting them go, i.e. unlike a computer they don't seem to scan and grab the fastest network as quickly as you'd want. You can turn wifi on/off to force the phone to grab the faster connection (if it's available).

If it really bothers you, using a dual band router with the same network name for both 2.4 and 5 should mitigate the issue.

but isn't there any way to Defualt the 5GHz.

Yes, there is....and it works fine.....but no better than 2.4 GHz in my experience.

John has already provided you with the steps, which are repeated again below.

As the link indicates, you first have to assign a separate name to the 5 GHz band on the AirPort router, then connect the iPhone to that 5 GHz network name.

Then, forget the other 2.4 GHz connection on the iPhone and it will default to 5 GHz signal every time.

If you are telling us that you do not know how to assign a separate name to the 5 GHz band on your AirPort router, post back with the model number of the device that you have and what version of AirPort Utility that you are using.

That's why my suggestions still make sense either keep 2 separate names but remember to toggle wifi on/off (airplane model, whatever is easier) when you're closer to the router/want to grab the 5 -or- opt for a dual-mode router with both 2.4 and 5 named the same and let it handle everything.

Right, but the issue is an iPhone doesn't scan networks the way a computer does. Once it grabs that 2.4, there's no reason to let it go from its perspective.

If you really obsess about this, I think it is well worth the $ to buy a better dual band router so you can stop having to manually manage the setup.

Thanks John, but isn't there any way to Defualt the 5GHz. It would still be good to have both 2.4 GHz and 5 GHz and just default to 5GHz.

That's essentially how Apple designed it, but in practice the 2.4 GHz network tends to have the greater signal to noise ratio, and is the one that iPhones will grab first and hold on to the longest, despite the fact it isn't capable of as much bandwidth as 5 GHz. What it appears you're looking for is a way to assign a preference for 5 GHz and automatically fall back to 2.4 GHz if 5 GHz becomes unacceptable, and Apple simply doesn't provide a way for its users to do that.

In crowded areas it's common to see literally three or four dozen 2.4 GHz networks within reception range, and perhaps one or two 5 GHz ones. In such an environment it may be better to constrain your devices to 5 GHz even when 2.4 may have the stronger signal.

Isn't there any way to sort the priporty of all the networks in the list like the way its done in mac? (the first link that that I shared)

No, the iPhone uses a very basic and limited feature iOS operating system.....and a Mac uses OS X. Big difference there.

Tap the 2.4 GHz network, whose name must be distinct from the 5 GHz network as described in that post.

Tap the blue circled i then Forget this Network.

Not that I'm aware of.
