ex7700 is NOT seamless mesh

Question

Hi,i got a r7800 as router and an ex7700 in wifi range extender mode.Tried in various ways to get those working in seamless mesh, as advised on the extender, but without success.I can't move between my house while doing a facetime, whatsapp or almost any web call app whitout losing connection and not reconetting until going back in the range of the router/extender where i have started the call.Skype works but it's just because it simply disconnect and reconnect, it could work also with any other network in range.Frustrating.Tried almost any firmware on both ends; tried moving positions; tried a lot of times hard reset both and setup from zero; tried using ip reservation, for extender, for devices, for both; tried changing wifi channels on both ends;&nbsp; tried using the modem connected to the r7800 in bridge mode or not.In my opinion the issue is related to virtual mac address and the net protocols involved in live calls on the web.Is there anything else that i could try?Thanks.

What modem/gateway do you have?&nbsp;what firmware is on the R7800?And firmware on the EX7700?How big is your home and what materials is the interior made of?&nbsp;Also, What device are you roaming with? This is key as its the device that decides to switch and not the extender/router.&nbsp;Are you using 2.4ghz or 5ghz during this? 2.4ghz is slower and more sensitive to interference.&nbsp;

-modem technicolor dga4132-firmware r7800=1.0.2.80 ex7700=1.0.0.216-walls are made of bricks and concrete and my house is about 150sq/m; this is the main reason that led me to buy an extender, there are black points where wifi signal drops, especially 5ghz. It happens in my kitchen where the signal from the router must pass practically 3 walls and drops really fast just turning an angle.-tried iphone 11pro, xr, ipad 2, windows laptop. wifi signal is strong, extender get maximum speed from router both in 2.4 and 5ghz. And apart the not seamless experience, speeds on devices are good.-router and extender are 10meters apart

the&nbsp;dga4132 is a modem/router combo device.&nbsp;Add in the R7800 and it can cause a double nat.&nbsp;&nbsp;Also, brick/concrete are literally 2 of the best blockers of wifi there is. The EX7700 is designed to use a 5ghz dedicated backhaul. And 5ghz is much more sensitive to materials and distance than 2.4ghz is. But 2.4ghz is much slower.&nbsp;&nbsp;so you're caught in a bit of a problem. Your home is made from materials that block wifi to a great extent. but you need wifi everywhere. Problem is wireless backhauls might not be feasible/usable in your home. You're welcome to try using several of them but many people resort to using a full mesh system and running a hardwired backhaul like ethernet, powerline, or moca adapters.&nbsp;

there is not double nat i have disabled it on dga4132 and it’s acting as a bridge. r7800 is doing all the job.the 5ghz backhaul works as expected, signals result in maximum speed from extender status.

and i add that i have granted an almost open space between the router and the extender. the “not seamless experience” (sorry i don’t have another word to sum up this) happens also in place where there is no big wifi signal drops,but just a change between the two networks.
