My iphone 7, iPad Air 2 and iPad Pro’s, as well as my 2015 MacBook Pro all connect perfectly fine over 5Ghz. My ASUS wifi router is set to auto for channel selection as the whole point of DFS is to allow channel hoping to avoid interference. Locking a router to one specific DFS channel seems pointless to me. My router is currently using channel 1 for 2.4Ghz and channel 157 for 5Ghz and works just fine.
P.S. Editing the router settings now to force use of channel 120 and it works just fine as before with auto channel selection (posting this from an original release 12.9” iPad Pro over channel 120 on an ASUS AC3100 router).
Canada does not allow channels 120, 124 with wifi routers (and a couple of others) as those frequencies are reserved for weather radars. Channel 151, which is not DFS, is available in both countries.
DFS differs between countries because different countries reserve different parts of the 5Ghz band for weather and military radars. The point of DFS partitioning of much of the 5Ghz band is so non-licensed device’s (e.g. consumer wifi devices) have plenty of non-reserved channels to pick from to avoid interference (without blocking out a huge chunk of the 5Ghz band). Any quality wifi router set to auto channel selection will simply pick the channel with the least signal interference. Whether or not that is a DFS regulated channel doesn’t matter (the DFS regulated portion is just part of the available 5Ghz band - 5Ghz is carved up into ~190 channels).
In the USA it’s channels 50-144. Other countries have their own laws and regulations as to what DFS channels are allowed. But again, the whole point of creating the DFS channels was to enable routers to dynamically switch, as needed, to avoid interference with weather and other radars. Setting it arbitrarily to a single channel somewhat defeats the whole point of subdividing the 5Ghz spectrum that way.
If you do have any interference on or near channel 120 (5590-5610 MHz) where you are, then that channel on your router is going to disconnect. The router cannot use a DFS channel if there is inference on it.
P.S. Canada does not allow all of the same DFS channels as the FCC in the USA does - so your router’s region settings need to be correct to enable all DFS channels legally allowed where you are.
Do you have a link where it told you it supported DFS?
I actually asked a similar question prior https://discussions.apple.com/thread/7837444 where I was told fully 5GHz complaint supposedly. Someone at the Apple Store said it should be compatible with DFS as well.
I'm in Canada. Lol. But you knew that. I know my router (Netgear R8000, and an EX7000 Extender in my bedroom/office) use Channels 11 (2.4G) and 151 (5G). They are set to auto. The EX7000 has the 2.4G signal off because it interferes with my Bluetooth speaker (Bose SoundTouch 20). But the EX7000 is set up so that it uses the 2.4G signal from the R8000 and converts that to 5G. So in essence, everything wired in or wireless will run with 5G speeds.
Am I missing something?
Learn something new everyday. Thank you for your explanation. On my R8000, I do have 2 5Ghz bands, which are split into Radio 1 and Radio 2. Radio 2 has the higher end frequency, Radio 1 has channels in the 40 range. I'm not sure, I have to double check. I did have the option of putting both bands together, but I kept them separate. Radio 2 is for my personal use, plus my Xbox One S is on that channel. Everyone else that has a 5Ghz device gets put on Radio 1.
But once again, thank you for your explanation. 🙂.
Are you asking whether it is DFS compatible or 5Ghz compatible? Or are you asking anything at all?
I know it is 5GHz compatible but is it really DFS compatible. Not really a question but more of an actual discussion. I was previously told it should support DFS but it isn’t looking like it does.
Yeah but DFS channels are actually a range between Channel 52 and 120 I believe.
Guess iPhones actually don’t support DFS
