@David-TP 

I am also running into the same issues.  To the extent this is helpful, adding some additonal data points.

For Internet, running AT&T Fiber through BGW320-500. IP passthrough to Firewalla Purple.

For router, using a Firewalla Purple.  Had both this and BGW in place with another WIFI system prior to going wiith Deco 85.

Using Deco 85 as an access point.

I've tested extensively, and the errors only occur when I go through the Deco 85.  Straight off modem, no issues.  Straight off Firewalla, no issues.

What was interesting is the erros persist even if I go direct through an ethernet port off the Deco.  They are also still there when connect to Wifi.

Per what another user reported, anything Apple is highly suspect to the download connectivity issues.  macOS updates, iOS updates, App Store downloads, etc.  Not exclusive to apple, but attempting to download big files (for example, a previous macos Version) through the macos App store is a pretty reliable indicator as to whether or not there is an issue.

Anyway, doing all my testing before I landed here, I thought the fact that whether it is wired or wireless through the BE85 might be useful in troubleshooting.

I'm running :   
BE85(2.0)
1.0.10 Build 20230815 Rel. 47787

  @David-TP thanks for the update.

I gave up and returned my BE85s because I needed a functional network.

In my opinion, the BE85 should never have been released in this state. Does TP-Link not do any validation or testing before releasing new hardware? It was trivial for me to reproduce the issue and I have no special knowledge of the hardware or access to the software stack.

Selling a broken product and making customers contend with an inability to even download files properly for five months is not how you build trust in a brand or products.

Even if the new firmware fixes the issue, I won't be giving TP-Link another chance anytime soon, if ever.

 @David-TP  Thank you for all of your time and keeping us in the loop.

I wanted to confirm that after running a whole battery of download tests after installing the beta (and then again after the produciton version which showed up on the interface shortly thereafter), I have not seen any issues.  Historically, those tests would fail at a pretty high rate.  I'm only a few hours in, but am highly encouraged.

WIth those failures hopefully in the past, combined with the incredibly high throughput rates that the BE85 is capable of, all signs right now are that the network is working beautifully.

Thanks again for keeping the lines of communication open.  Have a great day!

Hi David,

Do you know when the official firmware will be released ?

I'm running with Deco BE85_V1_1.0.11 and have still instabilities and data corruption issues.

Many thanks.

Hi David,

Yes it seems to work properly, I will perform some more tests tonight.

Thank you.

Hi David,

I performed some additional tests with this beta firmware and I observed no data corruption.

Many thanks.

Do you know if this fix is included in the most recent release, 1.0.13 Build 20230927 Rel. 38826.

The date appears to be after the Beta, however, when I upgraded to this version the network congestion issues returned.  I have since reverted back to the beta, but just wanted to make sure I wasn't missing something.

Thank you, sir.
