WiFi Calling stability on ATT Network
Opening this thread to document issues I've been experiencing with instability of WiFi Calling in my residence.
I can see my iPhone X either wander in and out of WiFi Calling during a phone call, or have WiFi Calling switch off completely and hand-off the call to cell tower usually with the result of losing the call. I've also seen cases where a call comes in, I go to answer with the ATT WiFi indicator on, and no sound can be heard by the caller or callee. Given the poor cellular coverage we have here is the reason why I place a premium on WiFi Calling.
After several calls to get to the bottom of this situation, many of which were with the mobility side, the solution still evades but points to the WiFi network in the house. Service is also provided by ATT via a BGW210-700 residential gateway. Channel is manually set to 149 to allow Amazon devices to connect.
I also have a TP-Link RE200 repeater I've configured both as an extender and as an access point, but presently as the former. It is set to only receive 5GHz signal from host and transmits only 5GHz signal to clients. The extender uses the same SSID and password as host. Upon further review, this is not allowed so reset back to default naming.
The house also has a VAP2500 WAP for Uverse TV. There is no signal congestion on WiFi verified with instrumentation. I have it configured to transmit on channel 112. I'll also mention as a secondary problem that the wireless set-top box will lose signal once or twice a day.
The iPhone X is connected on 5GHz radio.
Based on a call to internet tech support yesterday, we agreed trying an AirTies might better handle preventing errors on 5GHz by using Mesh technology, so tomorrow have an appointment to give this a try.
I'm tagging this in the wireless/Apple area of the forum based on primary usage of affected problem although this could easily be listed in other areas as well.
