UNABLE TO CONNECT, CALL DROPS, POOR CONNECTION - WHILE ON WIFI

1. What kind of phone do you have that is 5G capable, and can you just use LTE instead? That's what I do because I have a 5G plan and phone but 5G is unreliable where I live so I just use LTE all of the time. iPhone 12 Pro, 5G capable but no 5G service in my area still.

2. Have you tried WiFi-C (WiFi Calling) and is your phone capable of WiFi-C? Enabled and zero difference.

3. A cellular booster is really only effective if you have at least one and preferably two bars of consistent cellular signal strength to your home. You also need to make sure that whatever cellular booster you get, it works with the cellular signal that is being broadcast to your area. That's where a professional installer come into play. They should be able to determine the cellular bands and propagation that you are receiving at your home and recommend a booster that will meet those requirements.  See my Cellular Booster Tech Guide, the link is in my sig line.

Boosting your WiFi signal in-home (like with an extender) should help you to connect better if you are attempting to use WiFi Calling instead of cellular.

What kind of internet service do you have?

Cox Communications

I have an iPhone 12 with 5G service. Have you set your phone to LTE only?

WiFi-C should work if your phone is WiFi-C capable (which it is) and your line is provisioned for HD Voice (AT&T's version of VoLTE), which it probably is but it couldn't hurt to check with AT&T. Were you able to successfully activate WiFi-C using your address (which is an FCC E911 requirement).  WiFi, which is different from WiFi-C, should also be enabled at all times, regardless of whether you are using WiFi-C or a cellular signal.

Have you completely powered off your phone or Reset Network Settings? Do you have a new SIM card?

If everything for WiFi-C is correct and you've done all of those things then I would suspect your router's WiFi signal.

Yes it is provisioned and I have done all that. The problem is if you read back in the past part of the thread is I'm in a real shadow area that has never been improved by AT&T since i've lived here (12 years). The Ruckus extender was the last resort before trying another cellular carrier.

What kind of speeds do you get, your type of service,  and have you considered a mesh WiFi system? Are you using Cox-supplied equipment and does it have VoIP capability built in?

WiFi-C is dependent, for the most part, on how robust your WiFi connection is.

It sounds like your only options are to use WiFi-C (if you can figure out why it is not reliable), contact one of the cellular booster companies that are listed in my guide and have an installer or company rep come out and assess your situation, or switch to a carrier who offers better cellular coverage.

Already tried that if you look back upthread. Did not work and I had to return the equipment. I need someone who is familiar with the Ruckus device.

Can you hardwire the extender and what kind of coverage area do you need? Have you contacted Ruckus? Are you using Cox-supplied equipment and is your connection DSL, cable, or fiber? Have you considered a mesh WiFi system?

Yes the extender is hardwired. Not sure of the coverage area. Tried contacting ruckus but I am not a client and would have to go through the company that sold it to me. Using Cox supplied modem router. Connection is cable. Please expand more on the mesh Wi-Fi system.

So it sounds like you're using Cox's gateway (modem/router combo). My guess is that the WiFi portion of the Cox gateway either isn't powerful enough to supply an adequate signal or is not compatible with the Ruckus extender. If you disconnect (power off) the Ruckus and use WiFi from the Cox gateway, can you use WiFi-C? What kind speeds do you get from the gateway with the Ruckus out of the picture?

Basically a mesh WiFi system is a router with one or more satellites, nodes, or extenders that can either be hard wired or use WiFi for the private back channel to maintain connectivity to the router. They are very good at providing reliable, fast coverage over a large area (like a 2-story home for example). I use a mesh WiFi 6 system throughout my 2-story home and I get excellent, fast and reliable coverage. WiFi-C works extremely well anywhere in the house or on our property.

To use a mesh WiFi system with your gateway you would need to put it in either bridge mode or pass through mode to disable the WiFi portion which would allow the mesh router to handle all of WiFi and router functions. Some gateways are easy to setup, some are not, and some that are supplied by the ISP are configured specifically for the ISP, which may or may not cause issues. Does Cox allow you to use your own equipment or of you have to "rent" theirs?

I have Cox internet, I use their modem and then I have added a Google mesh system which is now several years old to make sure I have Wi-Fi throughout the house. Wi-Fi actually extends nicely somewhat into the yard and I have three and a half acres.

I have very little faith in network extenders. I don't know any more about this particular model you purchased other than what it claims in online ads.

Basically starts out saying they don't work. Read 4 and 5.  Even my Google mesh system does not seem to work well in my son's room which is over the garage and at the furthest point from the router. We wound up having to physically wire his computer to the last Google puck in our Network.   

If you have far reaching areas of your home that are not getting a good cellular signal and your Wi-Fi does not reach, that might be a good place for a cellular booster. In the end your iPhone 12 is a universal device, pay it off, unlock it, and try Verizon. 

Before I give up on AT&T and trial another carrier, a customer service rep suggested I try the new 5G SIM card. I doubt this will help. Any thoughts?
