@NeverAgain I'm sorry to read of your frustration.  Do you have 5 of the units each set up as router?  Or maybe one router and the rest nodes, (I hope)?

  @jzchen Thank you for your reply!

I've got one unit configured as router which is connected directly to my modem and the other 4 Deco units are serving as nodes.

Really bothers me this was removed, hopefully they'll comment on it being added back. For now we have to assume it's running? Not thrilled there's no communication on this entire post. Sure they can't make everyone happy, but they can feign it. 

  @WYLDSTALLYNS What do you mean by "backhaul option"?  Is this the display of the media used to connect two Deco?

Hey there, sorry to hear you are having problems. Always a bummer when things don't work. 

For what it's worth, I've have three versions of the Deco system. The Deco S4 (3 units), then Deco XE75 Pro (4 units), and just recently moved to the Deco BE95 (4 units).  Never had any trouble out of any of them, which is why every time I upgraded, I went back with TP-Link's Deco system. 

Is this your first Deco system?  When did you upgrade to the Deco XE75 Pro units?  What was your previous router? Have you had your ISP check your internet service from their end?  What type of internet service do you have (fiber, DOCSIS, satellite, etc)?

As far as speed of connection to the network, that can sometimes be a result of the client device itself.  For example, when I had the Deco XE75 Pros, I opened the 6 GHz band up to be used by clients.  The phone I had at the time was a Galaxy S21 Ultra which was Wi-Fi 6E capable.  It was slow to connect, and sometimes would not see the 6 GHz band right away.  Since then, I switched to the Galaxy S24+ which has much newer (and mature) network 6 GHz band capable hardware. It's sees the 6 GHz band instantly and connects much faster than the older phone. 

It is always possible you received faulty hardware.  It happens.  So I'd only troubleshoot for so long.  If you still have your proof of purchase and the place you purchased the Decos from has a return policy, I'd return for an exchange. 

@RestingCat...thanks for your reply!

This is my first time ever using TPLink products...and will be the LAST!!! The router I replaced was a Synology RT2600AC mesh router and I will say that router was rock solid. I had absolutely NO problems with the Synology router and had 1 main router and 2 nodes. Only reason I upgraded was to move to Wi-Fi 6.

I have a DOCSIS modem and the ISP has indicated no problems on their end.

My laptop has a Intel(R) Wi-Fi 6E AX211 160MHz network card in it and I literally just encountered these type of ping responses while composing this reply:

I tried upgrading the driver for the network adapter and downgrading the driver and nothing helped.

This router is effectively useless to me with these type of stability issues. Same type of instability whether I'm on the 5GHz band or the 6GHz band.

I can assure you, if I wasn't out of my return window, these things would already be boxed up and out of my house.

Thanks again for your response. As usual, no response from a TP-Link support personnel...pretty sad when a billion dollar company can't offer support for the junk products they put out!

  @NeverAgain Did you happen to review the Deco XE75 Pro's specifications and compatibility for your setup before purchasing?

  @DanielTan88 Compatibility in terms of what?

  @NeverAgain 

Have you tried changing the mode from "Wi-Fi router (default)" to "Access Point"?
For me, most of the similar problems disappeared when I changed mode to "access point" mode in the application.

  @Vuk_2024 Thanks for the suggestion.

However, the way I understand it, you would still need one (or another device) to serve as the router though? Problem is, if I had another device as the router and all the Deco's in AP mode, I'd lose some of the functionality I bought the Deco's for to begin with:

• Device Isolation
• VPN Server
• VLAN
• Connection Alerts

For the price I paid for these Deco's, it's very frustrating to have to sacrifice functionality to simply make these things work!
