I have been experiencing wifi dropouts when a call is made or received on a cordless phone system. The phone are DECT 6.0 and operate at 1.9Ghz, brand new system. This happened with two different phone brands and seems to happen more frequently after I upgraded the firmware to 2.6.1.36 on Orbi router and 2.6.1.38 on satellite. Using cable internet with verizon router set to bridge mode. Has anyone seen similar behavior? Any suggestions? Thanks.
Another datapoint - I also have a many-handset Panasonic DECT cordless system in my house and while we don't use our landline as much anymore, I have not noticed any interference and there have been zero dropouts along with our Orbi AC and Orbi AX systems.
Just to confirm - Is the OP using VOIP or a landline? If VOIP then there are other issues to investigate.
Interesting. VOIP via xfinity. Would be interested in hearing about that potential issue. As a datapoint, I somewhat recently switch to xFi modem to get the 1GB I was not utilizing, I don't recall if issues happened about then but first set it up not in bridged mode and just let the router get an IP from the modem. I switched to bridged thinking that the radio on the modem could have been the problem but it may still be serving up xfinitywifi, I toggled that with no apparent change.
Shot in the dark here... maybe a DSL filter on the backside of the modem?

My Panasonic cordless is also VOIP (Spectrum voice from the modem). I would think if line filtering is required,it would be internal to the modem. Certainly should not hurt.
I am confused again.
- Is the ISP AT&T or Xfiinity?
- This same thing happened with a different brand of cordless phone? (WiFi dropout when the phone is used. Every phone? Just one particular phone?)
- Any luck figuring out that 'rogue' 2.4G access point on channel 1? If your Orbi is on channel 10 that should not cause any overlap.
The ISP is xfinity. The issue was happening with both new VTECH and old panasonic. I have not fully debugged the channel 1 signal problem yet. Wiill keep you posted. Thanks for all the suggestions.

If your VOIP is xfinity then I don't think a DSL filter will help (you're getting it via cable). Your DECT issues happened with and without bridging the Orbi, right?
So your VOIP comes out of the xfinity gateway's phone line plug, then your Orbi is bridge downstream. Therefore your Orbi has no impact to the IP part of your VOIP, right? Or are you using some other VOIP gateway device and it's plugged into your Orbi?
If your VOIP is coming out of Xfinity's gateway then one simple test is to turn off your Orbi and then see if your VOIP is unaffected.
Phone line right out of xfinity xFi gateway. No intermediate VOIP device. Orbi is downstream from gateway bridged. In thinking about the setup, I have a switch behind the router for hardwired devices.... phillip hue hub. Maybe I need to start unplugging some of these and see what happens. I need to test again with the phones to make sure they are correlated.
Prior to the xFi gateway, I had a (woefully) slower arris modem with the orbi and never saw the problem. hmm

It sounds like everything is wired correctly, i.e., you have your Xfinity gateway bridged to your Orbi and everything runs downstream to it. Your successful prior Arris + Orbi setup seems to eliminate the Orbi as the source of your DECT interference, right?
Do you have any coax splitters upstream of the gateway or is it wired directly to your wall outlet? Did Xfinity install your new xFi gateway and used high-quality cabling? I know they always say that poor cabling and loose connections interferes with strong cable service, so I assume it can also affect VOIP performance.
