Recently replaced my Starlink Gen1 Router with a Deco 6E. Before the replacement my public IP bounced between San Jose, CA and Portland, OR. Weird, but close enough geographically that I just got used to it knowing how Starlink works. After replacement, the laptops on Wifi think I'm in Brazil. It's only laptops and only wifi. Iphones and the ethernet PC have not had this issue. But whenever I google something on one of the laptops I get answers in Portuguese and locations in Brazil. Which is not something I can just get used to.

Help?

Hello guys, I could really use some help on figuring out what is going on with my wifi. It started acting this way about a year ago but always figured it was the ISP. I used AI to help summarize my notes. They were a mess.

I’m trying to troubleshoot really unstable Wi-Fi speeds in my home and I’m not sure if it’s my mesh system or configuration. Speeds just constantly fluctuate from 1.8 to 300 mbps

Internet setup

Cox Fiber (ONT in garage)

TP-Link Deco AX3000 mesh (3 units total)

2 story house (~2500 sq ft)

Main Deco downstairs

1 satellite in loft

1 satellite in next-gen room

All satellites are wireless backhaul (no Ethernet between units)

Wired performance tests

Direct from ONT/wall Ethernet: ~943 Mbps down / ~699 Mbps up

Wired into main Deco: ~912 / ~681 Mbps

Wired into second Deco: ~748 / ~453 Mbps

Wired performance is generally good and stable.

Wi-Fi performance issues

Wi-Fi from Deco system: ~13 Mbps to ~300 Mbps (constantly fluctuating)

Even standing next to the main Deco, speeds jump wildly (e.g. 14 → 300 Mbps → 80 Mbps, etc.)

Issue happens on multiple devices:

Windows PC

MacBook

iPhones

What I’ve already tried / confirmed

ISP / ONT is fine (near gigabit speeds direct)

Main Deco is fine when wired

Satellites also show “strong signal” in the app

Still getting unstable Wi-Fi performance everywhere

Turning the system into an access point only did nothing

Quality of Service is off

Tp Link Deco is up to date

Hey everyone,

I’m dealing with an incredibly frustrating issue and could really use some expert eyes on this.

My home network keeps experiencing random drops where the internet goes completely out for exactly 3 to 5 seconds, and then immediately comes back on its own.

My Setup:

• ISP: Verizon Fios
• Desktop PC: Connected directly to the Verizon router via an Ethernet cable.
• Wi-Fi: A TP-Link Deco mesh system with a node in each floor (4 floors). The Decos are currently configured to run in Access Point (AP) mode, so routing is completely handled by the Verizon router.

The Symptom:
Whenever these random drops happen, BOTH my hardwired desktop PC (ethernet is connected to the verizon router) and all wireless devices on the Deco Wi-Fi drop offline at the exact same millisecond. Because my PC bypasses the Decos entirely and goes straight to the Verizon hardware, this rules out the Deco mesh network as the culprit.

Since it affects the entire house simultaneously but only lasts a few seconds, it feels like a hardware negotiation glitch, an IP conflict, or an issue between the Verizon ONT box and the router.

What I've tried/verified so far:

• Confirmed the Decos are definitely in Access Point mode.
• Power-cycled the entire network chain.
• Disabled the wireless radio/turned off Wi-Fi broadcasting from the verizon website router settings page

Has anyone with a similar Verizon setup experienced these micro-drops? Are there specific settings in the Verizon gateway (like IPv6 bugs or network card checksum offloading conflicts) that I should change?

Any troubleshooting advice would be massively appreciated!

Hi all,

I have no clue if anyone can help me or not, but I cannot for the life of me figure this out.

I have an Epson Stylus NX420 printer in my office and a Deco mesh network. Previously, the network consisted of 3x X55 models placed in our Den, our front room and our kitchen. When the printer was in the Den it seemed to connect without issue. When I tried to move it back to my office, I could not get it to connect, even though it had a good enough signal. I finally got a spare X20 I'd bought for our church and put it in my office and the printer was able to connect to it (by the way, the mesh network is connected to each other wirelessly).

Last month I upgraded my Internet to 2Gbps and needed a new AP capable of handling that speed going out. I replaced the main AP in my Den with an XE70Pro, then took the X55 that was in the Den and replaced the X20 in my office. So now my network consists of the X70 in the Den and then 3x X55. However, since I changed out the AP in my office, my printer will not connect anymore. No matter how many times I try, the traditional SSID/Password will not connect and when I try WPS it seems like it connects, but I still cannot get my computer to see it and the Deco doesn't show it connected.

Unfortunately the interface for the Decos is pretty limited so it's hard to do much troubleshooting, but I'm hoping someone here may have some suggestions. Thanks!
