Have been using mesh router = main XE75 (2024) + 2 nod unit X20 (2020)

Recently dunno why can feel that X20 has some issue like :
Wired : no issue, has internet
WiFi : connect but random no internet suddenly (browser just stuck loading, not moving; however not mentioning no internet)

I have to llike disconnect wifi from my device and re-enable it then it will connect (it might connect to my main and working fine)

Sometime have to reboot X20 then only fine

* FYI, all mesh are wired connection

Is it time to change router... ?

Dunno want go for Wi-Fi 7 model or not
BE series like no new model for the time being ?

I have two of xe75, the problem is lack of support since late last year because most of deco wifi 6/6e eol'ed
Last time got firmware update last October or November last year, until today no firmware update at all
If spend a lot of money just for wifi 7, stay away from tp link, better look for deals about Asus routers

Now tp link be series, software support I think is quite bad, new features slow to roll out (including the much debated DoT, DoH features.)

I brought a used maxis tplink ex510 thinking connect to my ax20 v1 as mesh, but cant seems to make it work, then i notice ax20 only has onemesh, while newer ex510 has easymesh. Any way to make it work with each other? i wanna provide stable wifi to one room far from router using lan cable to ex510. Ax20 v1 got any firmware update for easy mesh? i saw last time US site said they plan to update it but not malaysia site.
