AX1800 RAX10 Router - DHCP drops multiple times a day
Hi folks, I'm having a strange problem with my LAN and I'm hoping you folks can help. I moved to a new city a month ago and several times a day all the devices on my network lose internet. I can't...
Connected to the router:
Router
- TP-Link network switch
- Windows PC
- another TPLink network switch
- rasperry pi alarm clock
- ethernet-usbc adapter (to plug in my phone)
- another tplink network switch
- PS5
- tp link switch
- Mac laptop (via docking station)
(i know its a lot of daisy chaining. I don't own the house so have to make the best of what I have to work with. I've also tried plugging the Mac directly into the router and the problem comes back after a few hours.)
Distance from router to modem: ~10 inches of wire (came with the router to connect the modem). Physical distance between the devices is ~8 inches.
Modem: Spectrum EU2251. Found this on the spectrum site that lists my model number: https://d15yx0mnc9teae.cloudfront.net/sites/default/files/Spectrum%20eMTA%20User%20Guide-cross.pdf
Cables are all 5e or 5e riser. Noyafa cable tester confirms all cables are in working order.
Factory resets were run after leaving router and modem unplugged for 25 hours. After booting up the modem, I waited 10 minutes to make sure it was all ready, then booted the router, factory reset the router, then reconnected devices one at a time.
Traffic meter is off, enabled IPv6 based on a different thread. Will try disabling armor and running the setup wizard
Did you have this same daisy chain switch configuration at your last location?
What are the model#s of these switches?
I'd trouble shoot this by taking out all switches or only leave one switch online behind the RAX router. Possible this daisy chain configuration could be causing the problem. Also would recommend changing brand switches to something NG. Anything could happen with other branded switches.
3-6 feet distance between the modem and router is recommended.
My last location we were using Verizon fios. Same daisy chaining setup and roughly 6 years without any issues unexpected issues.
Switches 1, 3, & 4 are TL-SG105, Switch 2 is TL-SG108.
I ran the setup wizard and disabled armor. Things seem stable now but if I lose internet again today I'll try plugging directly into the router. Will post an update in a few days. Thanks for the help!K. Seen Armor do things as well. 🙄
Let us know...
Finally found my culprit.

Thats the adapter I was using to connect my phone to ethernet, and I'd plug my phone into it to restore the network. I noticed that the ethernet lights on it were blinking like they were transmitting data even when there was no device plugged in to it. Once I removed it my network stabilized. Tested by plugging it back in, network was down within 20 minutes, came back up within 1 minute of removing it.
(Went through all the other steps of disabling armor, turning off IPv6, factory resets on modem and router, left everything unpowered for 25 hours... Problems persisted until I removed that device.)Seems that its always transmitting something (though I don't know what) and in my house it will bring down the whole network if its powered with nothing plugged into it.
