Hello, I've had issues with my internet for awhile.  I've replaced my router, ISP, checked wiring and I can't seem to narrow down what my issue is.  I bought an Ethernet tester so I could check my cables.  All is good.  My set up now is Hiltron router to AX20 wan port I also have my wife's work computer hardwired to the Hiltron because this issue was affecting her.  I have 3 Deco E4's hardwired through a switches to the AX20 on each floor.  I have a streaming devices hardwired back to the AX20 either a switch in between.  I have a plex server hardwired to the AX20.  So I have 3 switches connected.  So my wireless devices are connected to the decos I don't use the wifi on the AX20 because of its location in the house.  Everyday, multiple times.  I can't access the internet.  I can access my plex server and the ax1800.  The iPad wifi says no internet under the network.  I've given my iPad a static ip and a different dns.  The problem resolved itself after a few minutes.  This doesn't affect my hardwire devices anymore but did before I got the ax1800.  when the issue happens I've done a speed test on a hardwire device and all is good.  My old net gear router would actually freeze and I'd have to reboot.   I've had issues with the Decos, with unifi AP's, netgear, linksys.  My Decos are setup in AP mode.  My DHCP is 100-200 and my iPad is statice at 10.  Any thoughts?

thanks
