How to prevent dropped wifi calls using an EX 8000 extender combined with 2 R7800 Routers

I have no cell service at our home and our cell phone calls using wifi calling regularly drop as we move from one room to the next. My current setup has 2 R7800s on each end of our house and a EX8000 in the middle.  Should the devices all use the same channel for 2.4 and 5 ghz?  Are there some setting that I should change?  Could the issue be switching from 5 ghz to 2.4?

 

Thank you,

Andrew

1. Is one of the R7800's running in access point mode? 

2. is the EX8000 running in extender mode or access point mode? 

3. are you using the same ssid between all 3x devices? 

4. how big is your home? 

5. are the phones on 2.4ghz or the 5ghz? have you noticed a difference?

One thing to try. 

If you're using the same ssid for the R7800's, the EX8000 might be switching back and forth between them.

Try setting one with a seperate ssid (for testing) and see how it works. 

Make sure the R7800 that is in access point mode uses a different wireless channel than the other R7800/EX8000 to prevent interference.

I had an issue before posting this thread where router #2 was connected to 2.4 and router #1 was connected to 5 ghz. Fixing that issue didn't resolve the issue.

The R7800 in access mode is on separate channels.  Should the 5 ghz channel match the router that is being extended?  By default, using smart setup 2.4 is matched but 5 ghz is different.

5ghz will be different because the EX8000 uses a dedicated 5ghz backhaul connection. 

 

If you just run the 1x r7800 and the ex8000, does it run fine?

I have the radio off on router #2.  Call still drops.  I verrified that my phone was connected to channel 44 on the extender and it droped as soon as it switched to 108 on Router #1. Setup picture attached if it helps.

so anytime the phone switches between router/extender or bands, the calls drop.

Does it happen on all devices? 

Maybe if the ex8000 is centrally located, give it a diferent name and just connect the phones to is so the phones aren't roaming between router/extenders. wifi phone calls don't use much data and don't require much thoroughput so even a weak connection should allow calls
