Hi There!

 

I have a setup of 4x Deco BE85 (Main + 2 x wired + 1 x wireless) and experienced abnormal wifi upload speed on selective device, some of my device could reach normal wifi upload speed while some were limited to around 300Mbps.  All device were connected to same MLO SSID 

 

Internet Speed:

2Gbps D/L , 1Gbps U/L

 

Testing App/Web

Speedtest.net

 

Normal upload speed samples (probably obtained 500+Mbps):

iPhone 14 Pro, iPad Air (M2) 

 

Abnormal upload speed samples (Seems have a ceiling of 300Mbps):

Intel AX211 (this couldnt even connect to 6GHz), iPad Pro (M4)(6Ghz)

 

Anything I could try? Thank you!

Hi, Does it help if we try to set the QoS to 2Gbps D/L, 1Gbps U/L?

How about the wireless download speed on these two devices?

 

By the way, will the upload speed get better when they are connected to the separate 6GHz SSID?

 

Wait for your reply and best regards.

Thanks David!

 

It seems no difference if I set QoS, I might give a try later today.

 

DL speed for both device are normal (say >1400Mbps, even on 5Ghz channel)

 

While that AX211 has some serious issues in connecting to 6Ghz network (i.e. neither the 6Ghz SSID nor the 6Ghz of MLO)
