There is a new failure mode I experience not uncommonly,
when 5G is available, but weak (or saturated?), my data performance drops off dramatically; my iPhone doesn't fail down, but keeps trying the 5G path even when it's not performing.
(I've also had this problem at the edge of WiFi range; data keeps trying to route over very low bitrate or packet-lossy WiFi... but if I turn off WiFi entirely, boom.)
- polartx 4y agoI have noticed this as well. Basically the same behavior as when a terrible (saved) Wi-Fi network is in range and my phone will not concede attempting to connect en lieu of a more performant cellular connection.
- bob1029 4y agoIs there not some wireless network protocol designed to deal with this issue, or is it one of those "sometimes" things? What actually happens to a TCP connection when you go from 5G to LTE and back?
- Doxin 4y agoI'm assuming 5G/LTE/etc works on the link layer, so TCP shouldn't notice at all aside from a dropped packet here or there.
