Re: 5G home internet keeps dropping

The Roku test was informative but what about connecting a small gigabit switch to LAN 2 and using a client or two multi-homed in effect. You could use the investigation client(s) with wireless to the ASUS and have an Ethernet connection to aswitch on LAN 2. If the client has issues hitting the internet through the ASUS then disable the wireless and enable the Ethernet port and check results. Maybe take a client and the Nokia router with the 2.5 Ghz wireless on a different SSID and look at results from that angle as well. TheAsus ac68u has four Ethernet ports as well as the 802.11ac so take advantage of the physical ports on the ASUS as well. Test and verify.If you have a client with multiple Ethernet interfaces and plenty of resources stand up some virtual machines as well. Linux would provide yet another data point and physical Ethernet LAN ports tend to just work with Linux. Lots of tools in the Linux environment to play with. Use different clients, Apple, Windows, Linux, Android, Raspberry PI clients. OK maybe I am making assumptions but today it is not uncommon to have all of the above. Another parallel investigation you can do is leverage your cell phone and if it is an Apple iPhone put it into field test mode. See if it communicates to the same tower as the Nokia router by confirming both report the same PCI values for the tower signals. Android phones have applications for tower location so yet another option. If you have not yet used cellmapper.net to validate the location of the tower your router connects to i highly recommend doing so. It is simple enough to use and very informative. What cellular channels are you linking to? How strong and clean are the signals? Do the cellular signals bounce/changefrom one channel to another? Do any of the local devices record errors or drops? Profile the behavior in detail. Focus on any device that can be influential and stands out but keep an open mind on other actors in the path. Use the web searches to get ideas but focus on the facts. The values and behaviors you can confirm. Don't overlook all the tools you can put to work. Keep notes and analyze the operation in a systematic periodic manner. The objective: Determine with more certainty where the problem resides. Look at the physical layer before you go up the stack. thanks for the detailed and thoughtful response. There's a lot to unpack there and I know I don't have the wisdom or time to get that deep in to this. getting the right dns config on the asus seems to have resolved the issue for me, at least for the last ~36 hours you mentioned you'd not tried the Pi-hole, it will only takes a couple of hours to set upand will improve your browsing experience. Twotips- don't go wild adding a bunch of blocklists; get the iOS "pihole remote" app to go along with it (stats are interesting and it offers the fastest way to temp disable the Pi-hole or add exceptions)1Ver0likes0ComentariosRe: 5G home internet keeps dropping

My current working hypothesis is there is some incompatibility between the trashcan and a separate router (LAN side) vs the t-mobile is dropping the internet (WAN Side) my prior working hypothesis). This seems unrelated, but I wonder if there is some MTU incompatibility between the WAN side of the asus and the LAN side of the trash can.https://amithkumarg.medium.com/resolved-t-mobile-home-internet-vpn-issue-2f5ca594c23eDoes not seem too easy to change the MTU on the asus though. Update on troubleshooting so far. Noticed that the WANDNS on my asus was pointing at my LAN pi hole….and DHCP on ASUS was giving out itself as DNS server to clientsThis was working OK when with Xfininity for several months. Have changedso that ASUS DHCP is giving out the Pi Hole as the DNS server - how it should have been all along.This has also had the effect of improving the statistics from the pie hole has it now no longer shows all queries coming from the Asus router. WAN DNS server on the ASUS is now Default, meaning is getting it from the Trashcan. I also turned off the 5Hz WiFi on the asus and turn it on on the trashcan, with the theory that if I use that while working from home & VPN in to work it should be more stable. That combo seems to of worked OK, meaning I've had about 12 hours of what I think uninterrupted uptime. Not sure if fixing the DNS server, or just changing the DNS server helped.. The advice to change the DNS server came from "Nater Tater"'s you tube channel - he has a bunch of guideson the t-mo trashcan.1Ver0likes0ComentariosRe: 5G home internet keeps dropping
