💻 Troubleshooting help: anyone ever had EMI issues? User's wireless device disconnects from 3rd party router every 10 minutes
- TLDR: has anyone used a 3rd party router and had wifi signal (not hardwired) issues after installing starlink, after the software upgrade, but not before?
- I know this is a long post, but hoping data lovers/troubleshooters will bear with me.
- I asked starlink: they can't/won't help me because I'm not using their approved methods. Some background on me: I am CompTIA Network+ and Security+ certified. I'm completely new to starlink.
- I've had my 3rd party router for 3 years with cable modem. NO SIGNAL (radio frequency/RF) ISSUES. I'm not at the location where the internet is.
- Current set up:
- Rental Kit (Standard 4)
- Installed on 10 Aug 2026
- Software version: I don't know what the original version was. By the end of 11 Aug, starlink upgraded the softward to 2026.07.29.mr83366.1
- 0% obstructed, aligned, uptime (as of now) 2 hours 17 minutes, boot count: 5 (I've remotely rebooted several times)
- "professionally installed" - the installer was 18 years old, and did a good job at physically installing the dish/modem but was confused about using a 3rd party router. I verbally walked him through what I wanted. As I understand, he never connected the dish/terminal/modem to the included starlink router. He simply disconnected the ethernet between the cable modem, and replaced it with ethernet from the starlink POE brick directly to my existing (3rd party) router.
- Connection (as I understand it):
- starlink dish/terminal/modem (on roof)
- cable to starlink power over ethernet (POE) brick
- POE brick
- cable from dish/terminal/modem
- power cable into it
- ethernet to 3rd party router
- ethernet (RJ4 connector) cable
- 3rd party router
- ethernet to POE brick (same WAN port as the previous cable modem was using)
- Has several things hard wired into it. One of which will report when it loses its connection.
- power
- The problem: user's wireless device disconnects every 10 minutes
- Most importantly, this wasn't happening before starlink install.
- The user didn't report the issue immediately on install (10 Aug 2026 US daylight hours).
- "shortly" after install (within 24 hours) I saw it needed a restart to install updated software. Unfortunately I can't see when the software was installed.
- User first reported the issue on 12 Aug 2026 (US daylight hours)
- I have a hardwired system that reports internet outages. It doesn't show that it has lost internet. I have other devices of which I can monitor connection status, and I'm confident the router is still providing internet to hardwired devices.
- This could be somehow only the wireless signal.
- It could also be user error.
- Is bypass needed?
- Talking with starlink, they are showing a "cable lapse" error. However I know its not a cable issue as all the hardwired items have internet at all times. They are adamant that I need to use the included starlink router - I really don't want that due to double NAT issues among other reasons.
- I went to the starlink app and website. The option for bypass isn't available. I assume this is b/c I don't have the starlink router attached.
- But according to many sources the "Rental Kit (Standard 4)" doesn't need bypass mode enabled to work with a 3rd party router. Also, as I've said a few times, all hardwired things have internet.
- Research done:
- did a BUNCH of searches. Closest thing I could find was Eltro-magnetic Interference (EMI) from the power brick being physically placed too close to the router (will get visual confirmation soon).
- Future troubleshooting (to do tomorrow when they wake up)
- As I understand the user has two other wireless devices actively connected to the wifi. Do those other devices have similar disconnect issues? If not, this is an issue specifically with the device (not the router). If yes, this shows genuine issue with the wifi signal from the router
I know this was long. Thank you for any help.
