Slow write and read speeds over Wifi 6 to my Unraid

[un4given]

Dear all,

 

hope everyones well. I bought a new laptop recently after selling my Gaming PC (Windows 10 Pro 64BIt, Build 19044) and it uses Wifi 6. 

I was pretty sure the tranfer speeds to Unraid would be pretty fine, since the new laptop is situated near router (1-2 Meters)

Wifi conncetion via Laptop.

 

 

But i determined with regret, that transfers to and from server are 10-12 MB/second (100 mbit cap)

I also have an Xpenology running and checked transfers to that server reaching 110-115 MB write and read speed.

Also Speedtests to Internet show me full ISP speed 500/50.

I also tried another Laptop with Wifi 5 and could get 60-80 MB to Unraid.

I was writing to Unraid cache (NVMe SSDs) where i normally get the full speed.

 

What am i missing? Why is WiFi speed to Unraid caping?

Hope some1 will have an idea

Have a nice Sunday

If you get better speeds with another laptop cannot see how Unraid could be the problem, could be your Wi-Fi router/ap, you can run iperf between various computers to test.

From the description you give it sounds like has to be something in your laptop or router that is limiting the speed.   You have confirmed that Unraid can getter speeds when the laptop is not in the equation.

Thx for the responses.

But this is the funny thing. I doubt it's laptops fault.

Over WiFi 6

Laptop to ISP - 500mbit

Laptop to Other Devices on the Network - 1gbit

Laptop to Other NAS - 1gbit

Laptop to Unraid - 100mbit while writing/reading to/from SMB share

 

So is it really my laptop? If it is, why 1gbit to other NAS (Synology)? This is the point where I am trying to solve a riddle.

 

P.S. going to use iperf now and see what comes out

To Unraid

P.S. iva got Intel AX200 Adapter on my laptop and those seem to have issues. Will maybe try to switch to another one.

 

But i as still confused: why is speedtest.net showing 500 mbit?

Slow as well, so not an Unraid problem.

sory, but i figured it out. it is an unraid issue. after i downgraded back to 6.9.2 the speeds went back to full write speed of 1gbit...gonna check out if 6.10.3 will do the deal, otherwise revert back. so 6.10 somehow borked the write speeds to cache drives. found other users on reddit complaning.

 

p.s. went to 6.11 rc4 and having no issues there. full expected write speed of 60-70 MB/s

Don't see how that could be the problem when you were getting low speeds with iperf, iperf only tests network speed, it has nothing to do with actual write speeds.
