Mine is doing same thing, done practically everything I can think of, and been on hold multiple hours multiple days trying to get ahold of advanced support. Ready to switch to starlink honestly
StevenL1 I hear you. This update feels like it bricked Ethernet on an entire series of devices. Whether it was oversight or neglect, the result is the same: paying customers are left with hardware that no longer works as advertised.
The only way we’ll know if Netgear intends to fix this is by how they respond. If they care, they’ll acknowledge the issue here and release a patch. If they don’t, silence will be our answer — and thankfully there are other options out there.
If anyone reading this is experiencing the same Ethernet drops after firmware v43, please add a short post here so Netgear can see how widespread the problem is.
do you know if it was an att update? or a Netgear update?
another 2 here👋🏼. just chiming in in case people in support notice. spent hours on support att support, eventually with advanced support. didn't seem like they had any notices of problems. even went to store and got new sim cards.
does anyone know if the problematic update was from att or Netgear?
After much complaining I got ATT to send me a new M7 to replace this M6. Will keep you updated, but hoping this will be a fix for me.
I asked for the same, but the customer (feel good) DEI person hung up on me!
AT&T is aware of this problem, but have no solution as of yet. Here is a synopsis of my testing:
Further testing determined the problem with access after installing MR6500 firmware update is only related to access to the hub via ethernet. Wireless works fine. You need to fix the bug that forces ethernet port to be ignored after a couple of minutes! Did you not test direct contact to the hub (router) via ethernet?! I have the json for the router if interested. Responsible people will connect the MR6500 via ethernet to another router or computer. This is no longer possible due to the bug.
any tips on getting them to replace your m6 with m7?
do you happen to know if the update at fauld was from att or Netgear?
deuxcv I'm certain it was the most recent firmware up update.
Mine drops at approximately 4 mins. After hard setting ethernet to 100 base T it increased to approximately 10 mins but still fails.
MR6110 Ethernet Port Drops After Firmware v43 Update (Wi-Fi Unaffected)
Detailed Description
After the latest firmware update (verMajor 43), the Ethernet port on my MR6110 no longer functions reliably. Devices connect for a few minutes, then drop, and the link cycles between connected and disconnected.I expected the Ethernet port to provide a stable connection (as it did before this update). Instead, it repeatedly drops out, even when using a clean run and a known-good gigabit switch.
Steps to Reproduce
- Connect MR6110 via Ethernet to a TP-Link SG105 gigabit switch (or directly to a laptop).
- Device (laptop, Roku, etc.) initially connects and gets an IP.
- Within 2–5 minutes, the Ethernet link drops.
- Device attempts to reconnect, link reestablishes briefly, then drops again.
Expected vs. Actual Behavior
- Expected: Stable Ethernet connection at 100 Mbps or 1000 Mbps, as before the update.
- Actual: Ethernet port drops repeatedly. Wi-Fi continues to work fine.
Environment Details
- Device Model: Netgear Nighthawk MR6110 (AT&T variant)
- Firmware Version: v43 ("verMajor": 43 in model.json)
- Connection Type: LTE B14 + Band 2 CA
- Signal Quality: RSRP –86 dBm, SINR 16 dB
- Downstream Equipment: TP-Link SG105 (gigabit switch), Linksys E5350 (Fast Ethernet switch), Windows 10/11 laptops, Roku
Error Messages and Logs
No on-screen error messages, only Ethernet link drops.From model.json:
"ethernetSpeed": "100M", "ethernetDrvEnable": true, "profileList": [ { "id": "1", "ethena": "On", "ethspeed": "1000Base-T" }, { "id": "2", "ethena": "On", "ethspeed": "2.5GBase-T" } ]
Indicates the hardware supports 100M/1000M/2.5G, but currently only negotiates 100M and drops regardless of setting.
Frequency and Timing
- Issue occurs every time Ethernet is used.
- Started immediately after firmware v43 update.
- Ethernet was stable on prior firmware.
Troubleshooting Steps Taken
- Forced MR6110 Ethernet to 100BASE-TX.
- Forced MR6110 Ethernet to 1000BASE-T.
- Tested direct laptop connections (short patch cable).
- Tested with TP-Link SG105 switch.
- Tested with Linksys E5350 switch.
- Restarted devices and MR6110.
- All result in the same drop behavior.
Additional Context
- Wi-Fi performance remains normal (stable at 50–120 Mbps).
- The issue affects all downstream devices, not just one.
- Multiple users online are reporting similar Ethernet failures post-update (Reddit, Netgear forums).
Bigbadbird - thank you very much for your detailed tech troubleshooting/ reporting.
I hope Netgear takes notice and provides a fix for this latest update issues.
I've got another M6 on the way so we'll see if that makes a difference. Since so many of us are having same problem, I do feel it's an induced problem due to the update.
Anyone got answers from Netgear yet?
AnnetteL please keep us apprised of the status of your most recent M6!
I have not heard from Netgear.

Got a refurbed MR6500 in today. Installed and it works like a champ. Ethernet port works as it should. We are back in business!
Same issue. Has a fix been posted. Or a way to rollback recent update?
Same problem, ATT just wants to send me a new router but feel will have the same problem. Anyone been able to downgrade firmware.
I have multiple ones doing the same thing. I can't even get through to ATT's tech support. I believe the only fix is going to be to another firmware.
Happening to me as well even done full factory reset
