Model: Deco X60  
Hardware Version: V3
Firmware Version: 3.9.76

My wifi is very slow since I had a power failure.

 

I restarted my modem and the Deco router, still slow

I updated my wifi card, still slow

I updated the Deco X60 firmware, still slow

I optimized the network, still slow

I deactivated UPNP, SIP ALG, Beamforming, still slow

 

The only thing I have not done so far, is change the channel, could you tell how ?

Is there anything else I could check ?

 

Thank you

I have reset all my pods to factory settings, deleted the Android app, and restarted from scratch.

 

Everything is working well again.

 

Thank you

Hi, welcome to the community.

Please also turn off QOS if it has been enabled.

 

Was the WiFi speed slow even when connected directly to the main Deco X60?

- Can I have some screenshots of the speed test results?(Please make sure the tested client is connected to the 5GHz WiFi.)

-It would also help if you could help me check the wireless link speed on the tested client: How to check the associated/link speed on a wireless client

 

How about the Ethernet connection speed from Deco X60? Is it as fast as expected?

 

By the way, the current firmware of Deco X60_V3_1.3.0 doesn't support changing wireless channels.

Wait for your reply.

Best regards.

Hi, thank you for the reply.

 

QOS is/was disabled

 

Wifi speed 

 

Ehternet speed 

 

Associated/link speed WIFI Sorry for the french screen.

 

Based on the results, seems that my pc receives the right speed, but for some reason, the speed test doesn't reflect the right speed ?

 

So my Deco X60, is actually giving the full speed ?

 

Any idea ?

 

Thank you.

Hi, I forgot to mention that both my laptop and computer have the same slow wifi and have different wifi adapter.

 

Everything was working fine, until, I got a power failure for a few minutes.

 

Since then, the wifi speed went down from 400mbs to 20 mbs.

 

The only last solution I can think of, is to reset all my Deco X60 pods to factory settings, delete the app from my phone.

 

Restart everything from the beginning.

 

Anyone has a better solution I could try ?

 

Thank you

Another strange thing.

 

I used two different Android phones to test the WIFI speed, and the speed is 350-425 mbs, which is very good.

 

On my laptop (realtek wifi adapter) and computer (killer wifi adapter), the speed is 10-20 mbs max ?

 

Thank you

Hi, please also try the following suggestions to see whether they helped:

1. Disable "Fast Roaming" and "Beamforming" under Deco App>More>Advanced.

2. Turn off "Mesh Technology" for the laptops (realtek wifi adapter)+(killer wifi adapter)

By the way, can you help me find the correct model numbers of the Realtek and Killer adapters, such as RTL8811AU and Killer 1550I?

Best regards.

Thank you for the reply.

 

I restart my laptop and pc everyday, and still not working.

 

Both my wifi adapters (laptop and pc) were working fine before the power failure. 

 

Since I use a surge protector, I eliminated that possibility from the beginning.

 

Thank you
