Model: Deco BE85  
Hardware Version: V1
Firmware Version: 1.1.3

Hi,


If I connect a BE85 to a TP Link 3016F via SFP+ (5110-LR transceiver), the upload speed to the internet of an iPhone 16 Pro Max goes from 450Mbps to 250Mbps. If I connect the BE85 to the internet via the 10Gbps RJ45 port (to a TP Link SG2218), the upload speed of the iPhone goes up to 450Mbps.

 

If I connect a laptop directly to the BE85, on an Ethernet port, the upload speed is 450Mbps, so the issue isn't with the SFP+ port, it has something to do with how the traffic for this particular client is being forwarded to the SPF+ port.

 

If I connect via Wifi with a Macbook Pro, the download speeds are worse, but the upload speeds reach 320Mbps.

 

The Deco is operating in AP mode. I had similar issues in router mode.

 

These are worse results than what I'm getting from my old Deco XE75.

 

I updated my Deco BE85 to the 1.1.3 firmware, but everything seems the same (perhaps even slightly worse).

 

What can I do?

 

Best regards,

Alexandre

 If I connect the 10Gbps RJ45 port of the BE85 to an Omada MC420L media converter, and then connect that media converter to a 10Gbps port (SFP+, using SM5110-LR transceivers), I get the same 200Mbps upload. Can it be some sort of failed port speed negotiation?

 Just connected a laptop to the other 10Gbps RJ45 port, while the BE 85 continues connected to the media converter, and the upload speed is 450Mbps. Something funny is happening with the handling of the traffic of this iPhone, but only when the port is connected to an optical port somehow.

Hi, does it make any difference whether the iPhone 16 Pro Max is connected to the MLO network or the 6GHz network, even the Main WiFi/5GHz network?

 

Or no matter which wireless network is connected, as long as the main Deco BE85 is connected to the SFP+ port of the front switch via a media converter MC420L or 5110-LR transceiver, the upload speed of iPhone 16 Pro Max is capped at 250 Mbps?

 

Wait for your reply.

Best regards.

  @David-TP hi,

no difference at all. Meanwhile I ordered some BE25 and a SG3210X-M2 switch, and I'll see the results I'll get, but it all points to different wireless traffic handling of the iPhone when an optical uplink (or ethernet via MC) is used. 
 

the transceiver is also getting very hot when used in the be85, despite being optical.

  @David-TP if I set the optical port on the ER8411 that's connected to the BE85 to 1Gbps, then the upload speed on the iPhone goes to the max, at around 450Mbps (my max upload speed on my internet connection). So it seems that there's a bug when the link speed is 10Gbps, which matches my previous findings, even with a media converter (since it was set at 10Gbps).

 

I can't test with the media converter at 1Gbps, since the 10Gbps RJ45 port on the BE85 doesn't seem to want to link at 1Gbps.

Hi, Thanks for the update.

It seems you have now identified the following two triggers.

Uplink port is connected to SFP+

Uplink speed is 10G

 

You have done 4 tests:

#1

BE85(10G SFP+) to  TL-SX3016F via 10G SFP+ (SM5110-LR transceivers)，
iPhone 16 Pro: upload is capped at 250 Mbps

 

#2
BE85(10G RJ45) to an Omada 10G MC420L media converter, and then connect MC420L to TL-SX3016F via 10 SFP+ (SM5110-LR transceivers)
iPhone 16 Pro: upload is capped at 250 Mbps


#3
BE85(10G RJ45) to TL-SG2218 via the 10Gbps RJ45 port
iPhone 16 Pro: upload is 450 Mbps

I noticed the SFP port on TL-SG2218 is 1 Gbps. Have you tested the following  topology:

BE85(10G RJ45) to an Omada 10G MC420L media converter, and then connect MC420L to TL-SG2218 via 1G SFP

What would the upload speed be on the iPhone 16 Pro Max?


#4
BE85 to ER8411 via 1G SFP+
iPhone 16 Pro: upload is 450 Mbps

If the tested topology is like:

BE85 to ER8411 via 10G SM5110-LR transceivers

Would the upload speed be capped at 250 Mbps again?

 

Wait for your reply.

Best regards.

I don't have 1Gbps SFP+, but I tested with a 10Gbps SFP+, connected via the media converter to a 1Gbps port in the SG2218. I got max upload speed. 

 

#4

Same issue, no 1Gbps SFP+, connected via mc to a 1Gbps RJ45 port in the ER8411. Max upload speed. 

This seems to prove there's an issue handling wireless traffic when the uplink port (either RJ45 or SFP+) is at 10Gbps, at least with traffic from an iPhone. 

 

 

On an iPhone 16 Pro M, I got max download speed, capped upload at 250mbps. 

On an iPhone 15 Pro M, below max download speed, capped upload at 250mbps.

On an M1 iPad Pro, below max download speed, but max upload speed. 

 

So, this issue only happens with iPhones and when the Deco BE85 is connected via a 10Gbps uplink. 

 

You should be able to replicate this scenario easily at TP Link. Do you have a timeline of when this issue will be handled? I need to make a decision until May 15th, when the return window for these expire.

  @David-TP Connecting the BE85 to a QNAP switch in a 10G port, and I get max upload speeds on the iPhones, so it seems this is just an issue when the BE85 is connected to TP Link switches.

Hi, thank you very much for the details. I'll escalate your case to the senior engineer first for further assistance.

Please check whether you can receive my email later.
