This is most likely to occur when both
Bluetooth and Wi–Fi are contending for
the same 2.4GHz radio frequencies.
The issue has probably come to light
here because of the increasing use of
both wireless modes to integrate iOS
devices and Macs, which has greatly
increased local radio traffic.
One quick trick you can try is to turn
off an iOS device and move it to a point
out of range of any other Bluetooth
devices, but well within your Wi-Fi
range. Turn it on again there and it
should enjoy full speed Wi–Fi
connections again.
Configure your Wi–Fi router so that
its 2.4GHz and 5GHz services have
slightly different names, but common
password and other details. Then in
Settings on each iOS device, go to
Wi–Fi to configure this “new” 5GHz
network, and enable it. You can then
disable the old 2.4GHz network,
keeping that in reserve in case of
problems with your router. This
should restore your previous Wi–Fi
performance, and shouldn’t suffer any
significant radio interference. However,
if this doesn’t solve your problem, you
will need to look for other sources of
interference which might have
coincidentally started.
There are other free tools available
which can help with this, such as
Broadband Checker, and Fing – both of
which are available to download from
the App Store.
Bluetooth slows Wi–Fi down
Since upgrading both my iPhone and iPad to iOS 12.4, their Wi–Fi speed has dropped from
36Mbps to less than 1Mbps. Normal speed is restored when I turn their Bluetooth off. How
can I restore their Wi–Fi speed without having to do that?

IN iPLAYER OVER 4G
MOBILE DATA?
Some services and apps,
like the BBC iPlayer, limit
download or streaming
of video, even on a 4G
connection. Other
commercial services, such
as Amazon, now support
this. One workaround is to
make your iPhone a mobile
hotspot, and download from
that over Wi–Fi to your iPad,
which is permitted.HOW TO TELL THE WI–FI
CHANNEL MY IPHONE
IS USING?
Install Apple’s free AirPort
Utility from the App Store.
Open that app in Settings,
and enable Wi–Fi Scanner. In
the AirPort Utility app tap
Wi–Fi Scan at the top right,
then tap Scan to see channel
details. Ensure you disable
Wi–Fi Scanner in Settings
afterwards to save power.If your Wi–Fi has both 2.4GHz and 5GHz support, give each
network a different name so you can run on 5GHz for speed.Tech Support & Techsplanations
