Hi everyone,

Every so often, the entire Decos or some Decos drops for 30–60 seconds and then recovers or sometimes i need to restart the Deco.This happens on both wireless devices and wired devices (like my PC connected directly to a sub Deco)
and little bit of some devices not connecting like my main phone is connecting fine and my other phone says "Failed to connect" or "can't assign an ip address".

However, my main ISP router stays completely fine and connected to the internet the entire time.

Current Network Topology:

onu -> TP-link AX50 -> cudy GS108 Switch -> main and sub Decos X20 -> End devices(Clients)

Current Settings & Troubleshooting Done:

1. Operating Mode: Set to Access Point (AP) Mode.
2. Firmware: All Decos and the router are on the latest firmware.
3. Power/Temps: Gear is reliably powered and cooled.
4. Current Suspect: My central switch is currently a Cudy GS108. I suspect it might be dropping IEEE 1905.1 multicast packets or triggering loop protection during Deco backhaul transitions, causing a broadcast storm that takes down the wired ports.

Questions:

1. Does this sound like a classic switch/loop detection issue with Deco's IEEE 1905.1 Ethernet backhaul protocol?
2. I am planning to replace the switch with a TP-Link TL-SG108E (and disable Loop Prevention in its settings). Will that completely solve the backhaul loop issue?

Can somebody tell me why 'Specified Connection' doesn't work for devices when selecting it in the app?

One device I want to connect to a specific hub, doesn't.

I turned off 'Mesh Technology' for it. I've rebooted the mesh and device several times, but it just doesn't obey this setting.

What is the point in having it in the Deco app if it does nothing?

Not only that, the 'Specified Connection' option for the particular device has vanished from the settings.

Looked it up but all the results I could find were for decos

I’ve looked in the tether app and the browser page when connected to the router, found the settings for MLO and things like that but not the beamforming

Does this mean beamforming is on by default? I would be surprised by this because other advanced options are usually off.

Hello,

I have a TP-Link EAP110-Outdoor (EU) V3.0 with firmware 5.0.1.

I am looking for the official firmware file:

EAP110-Outdoor(EU)_V3_5.1.3 Build 20250709

(or 5.0.7 Build 20230410).

The support website only shows the Release Notes, but there is no firmware download file.

Could you please send me the official BIN firmware file or a direct download link?

Thank you very much.

Thinking of buying these

I live in a 110 m2 house with concrete walls.

I have ftth 500mbps connection. The isp router is on one end of the house so at the bedrooms I get signal but not speed (10mbps out of 500). I have an ethernet connection from the router to one of the bedroom and was thinking of buying the 2 kit

. My plan is both wired one next to the router (and completely disable the router wifi) and one at the bedroom. Near the isp router is my office where I have my PC and where gaming takes place while the bedrooms only need to stream movies.

Could possibly go with only one device at the bedroom but I don't want to have to change networks and I fear compatibility issues with same ssid on the router and x10

What you guys think?

I’ve had a reoccurring issue with the TP Link extender- it works great for a couple of months and then the 5G randomly drops.

Trying to reconfigure is a laborious task, but I normally eventually get the 5G one back up and running.

This time I’ve tried a series of rebooting WiFi from the modem (several times), resetting the TP Link, rebooting extender from the app and Factory Default Restore. I’ve also installed the latest firmware update.

None of these have resolved the issue.

I can connect to 2G no problem, but my network doesn’t show when I go to connect to 5G.

Looking at troubleshooting, it says to change the channel for my WiFi’s router, but this isn’t an option with a Sky hub.

I noticed there’s an Ethernet slot. Is it worth me buying an Ethernet cable to help it connect and find the 5G?

I’ve been trying to get it working for 3 days now and would appreciate any guidance.

Concerns TP-Link WR902AC (EU) v4

Not sure when this started happening as I don't use this router very often, but I suppose it must have been shortly after the purchase (Dec 2025). Wireless 5GHz just doesn't work:

• the default "TP-Link_xxxx_5G" network does not exist
• when in "share hotspot" mode it only finds 2.4GHz hotspots
• the "Status" page says "Wireless Radio: Disabled" in the "Wireless 5GHz" section, even though it's clearly enabled in the "Wireless 5GHz | Basic Settings"

I tried resetting to factory defaults. I tried upgrading firmware to the latest one (250821, previously on 230506). Nothing.

Should I assume this is a defective unit?

Rebooted, tried the mobile app, nothing seems to work. It says the file is too large. I see where you can download the file to your computer and browse to it for the update but I cant file it to download anywhere. Anyone have any help on this?

Thanks

I have disabled turning off the device to save power. I am on the AMD high-performance plan, checked the drivers and reinstalled them, changed USB ports, and changed the wireless mode from auto to 802xxxxx, still to no avail. I have changed bands on the router to less congested ones and turned off Smart Connect, and I still face this issue. Please help

Hello good morning

I have a two storey townhouse with my main Deco M4r on the 1st floor in router mode (FW 1.1.8 20190917 rel 76172) connected to ISP box.

Ground floor has another Deco (FW 1.1.8 20190917 rel 76172) connected via ethernet to the 1st floor deco.

My second floor has 3 units in a room (4m x 4m). The FW levels are 1.5.5 build 20220823 rel 41353 and (FW 1.1.8 20190917 rel 76172).

Now my network is stable but every couple of weeks I have to restart the DECO's as the speed drops to less than 40mbps from 150mbps.

Should I update the firmware and possibly sacrifice stability?

Hi everyone,

I set up a wifi network at a friend's house: an Omada OC200 controller with 7 EAP225 (AC1350) APs distributed around the house, on an unmanaged switch. Since I don't live there and don't have much time to visit in person, I'm trying to figure out the fix remotely. My friend is going to give me access to his Omada Cloud and the exact modem/router model, so I can share those details if needed.

Everything worked fine for the first few weeks. Then we added IoT devices to control the house, and that's when wifi started failing — but only when visitors come over.

In the app, connected devices are always between 50-60, well distributed across the APs (no single one is overloaded). The only fix that works is a full power cycle of everything: router, OC200, switch, and APs. After that we have to reconnect fast to "claim" a spot, and if visitors stay long we end up repeating this.

What I've done so far:

• Created 3 SSIDs: IoT devices (2.4GHz only), guests, and main devices.
• Switch is unmanaged, but with so few devices I doubt that's the bottleneck.

Haven't tried anything else yet. An LLM suggested it could be channel interference between APs, or the ISP router capping at ~60 devices — but I'd rather hear specific opinions from people who actually know Omada setups. What do you think is the most likely cause?

Hello 👋 hoping to get a little help setting up my mesh network.

I have a full fiber connection from my ISP. When I follow the instructions in the app for setup and try to create my WiFi network, the deco LED turns red and the app says it’s unable to connect to the internet. This is with the deco connected with the provided rj45 to the ONT provided by my ISP on setup. Internet connection type is set to dynamic.

The only way I can get the deco to work is by having my ISPs original router connected to the ONT, then using the provided rj45 to physically connect from the original router to the deco, at which point the deco is able to access the internet. However, the point was to get rid of the provided hardware and upgrade entirely to a mesh system.

Does anyone have any ideas on what I’m doing wrong?

TPLink Deco BE9300 (BE65) WiFi 7 mesh system, pack of 3

ISP is Vodafone

ONT has been reset/power cycled multiple times
Deco has been reset/power cycled multiple times, and tried setup from scratch multiple times too.

Ethernet from ONT works on the original ISP router.

Have tried Dynamic IP and PPoE internet connection types.

The hardware is straight from the box, brand new, so should be the latest hardware and firmware type

My living room Deco shows as connected, but it isn’t connected. I decided to factory reset it and try to add it back to the network, but the app still shows it as connected. When I try to remove the satellite Deco from the app, I receive the error message: “Unable to remove. Please try again later.” I'm currently unable to do the following: remove a satellite deco or reboot my deco network. I have the Deco XE75 Pro. Has anyone else experienced this issue, and how did you fix it?

I am using AX10 and facing lag issues inbetween even my ISP is proper at another house.

Can someone ping in the best settings for me?

I followed the official guide for resolving this issue, but I had no luck. I also factory reset my router, checked the cable, but no luck.

When I connect my laptop to ISPs modem, it works just fine. But, when I connect my Archer AX73 to the modem via a working CAT 5e cable, it is not even detected on my modem, and it says that WAN is unplugged when I enter Archer's admin panel.

Also, is there a universal global warranty for these devices? i.e can I bring it to any licensed TP Link service shop and get it fixed? I bought it 11 months ago, and I believe it should still be covered.

P.S I checked this thread from 2 years ago, where someone had the same problem, but I couldn't find anything that resolved my issue

My Wi-Fi node is placed fairly close to my set up but not too close so that is messes with the signal. It was 1 of 3 nodes in the house and the internet speeds on the phone in my room (Furthest room in the house) reaches over 100 mbps up and down. Whereas my pc is capped at around 18. I don't know how to fix this problem. My ethernet cable is not the issue as I got a new one that's cat8, a bit overkill but it was pretty. Regardless of what ethernet cable I use though, it was still capped at 18.

Choosing between Deco X50 and BE25 — looking for real‑world range/stability feedback.

Understand BE25 is Wi‑Fi 7 with a 2.5Gb port, X50 is Wi‑Fi 6 with 1Gb. I’ve seen people say the X50 is more stable in older houses.

My home is ~220sqm with dead spots on one side and out on the patio. I mainly want better stability and coverage, not Wi‑Fi 7 speeds.

Anyone have opinion?

Hey I’m in the UK with Vodafone and Cityfibre. My Vodafone router was water damaged today due to a leak in my apartment and doesn’t turn on. I’ve got a replacement coming on Tuesday but I’m trying to connect a few Archer C6 and C7s I had lying around at my business premises.

I got the username and password from Vodafone for PPPoE and I’ve tried all 3 routers and in the quick setup it says failed.

I’ve had Vodafone support on the phone who couldn’t figure it out either and they’re now closed.

I can’t seem to understand what I’m doing wrong?

Factory reset routers
Connect to ONT
Go to 192.168.0.1 on my pc/phone and follow the quick setup

Repeatedly failing.

Any ideas?

I know very little about networking so step by step instructions appreciated.

Archer C7 AC1750 ver 5.0 (x2)
Archer C6 AC1200 ver 2.0

‏What are the features of this update? Did anyone talk? Do I update or wait yet?
