I have a strange request.
With those with iPhones and both 2&5Ghz WiFi, would you
Please do a test for me?
With phone on 5Ghz, walk away till it drops signal and document:
What it does: Does it go to LTE DATA? Or, does it go to
Also tell me what WiFi MFG box you are using.
Reason why I ask:
I have Two different 5Ghz MFG units, and the two do not work the same, as seen by iPhones. One switches to LTE DATA and then 10-15 seconds later back to 5Ghz,
And the other switches to 2Ghz WiFi.
If it were me, I either would not worry about it, or I would switch to 2.4 ghz, unless you live in a densely populated area (like you're in Manhattan).
Not to ask the obvious, both have credentials to login to the 2.4 ghz SSID, right?
imho if one doesn't live in Manhattan in a high rise, there's no need for 5 ghz. The benefit of 5 ghz is less co-channel interference, and faster "theoretical" throughput.
It's likely not available for iPhone, but for android and PC, there are enterprise grade wifi sniffers that are free. You would be able to see the actual throughput of a 5 ghz SSID is often not any faster.
For example in my dining room, the 2.4 ghz is -54db and 216.7 mbps achievable. The 5 ghz is -76db and 195 mbps.
Why use 5 ghz, then? Because if I lived in Manhattan there would be tons of co-channel interference with thousands of networks competing and using 3 channels. But I live in a single family home.
When you go out of range of your 5 ghz SSID there has to be a release and a transition. This is dependent on your radio and the access point. For your test, you'd want someone with the same phone, and different phone, to duplicate what you are doing in your space, not so much their space. my .02
There are only 4 houses within receiver shot of our house (halfway up mountain in western North Carolina)... and those 4 each have 2-3 different WiFi's on 2.4Ghz... Add my 1, and that makes about 10 signals spread all over each other.... Our 2Ghz is on CH11.
5Ghz is wide open.... And there are only 3 there, and all are ours! Roku remote control is on CH161, Our House on 153 and Garage on 48...
So my need is still there... So I still would like to see what others turn up.... in their experiments for me!
I'm using inSSIDer for RF examinations... Pretty good! Recently I used it to troubleshoot Neighbor near top of mountain's intermittent loss of connection with her security cameras... Remote access to cameras involves going through both Systems.... Turned out to be her house WiFi and Security System WiFi was on same channels.... I couldn't gain access to her security system, but changed her house away from Security WiFi, and all intermittent problems ceased!
Recently someone suggested a setting in iPhone that I didn't know about: Settings/Cellular/WiFi Assist.... I plan on testing that today, once it stops raining.... There is a location halfway between house and garage where 5Ghz Signals are weak enough that I can test this quite easily with both 5Ghz Wireless Synology House and Linksys Garage 5Ghz feeds...
That is, when it stops raining....
With WiFi assist disabled..... when Synology 5Ghz is dropped, still goes briefly to LTE DATA, but then immediately picks up Linksys 5Ghz WiFi!
However, when Linksys 5Ghz is dropped, it now goes to either 5Ghz or 2.4Ghz
So....... Yes! iPhones have something to do with it, but there is still some MFG specific actions that appear to be being applied as well!
I know there is a Synology firmware update in the works, and complaints have abounded on 5Ghz WiFi dropping for quite some time now.
Between U-APSD on Router, and WiFi Assist On iPhone both being disabled, maybe this will have “to do” until a firmware update comes out?
