AirPort Express slow download speeds (good upload)

Hi all!

So, here's my issue: My AirPort Express worked great until yesterday allowing speeds of up to 100 Mbps for download. Yesterday something happened and download speed went way down, to 10-20 Mbps but upload is still 60-80 Mbps across multiple devices. When I connect PC with cable to the same Express, it gives 80/80 Mbps.

I tried everything I could think of (resetting router, with settings) – nothing helps. There was no changes in network configuration, devices or ISP.

Can anyone help? 😐

I have fixed it!

Curiously enough, I needed Windows version of AirPort utility for this 😐

What I think helped is to uncheck "Use wide channels" option. This changed 5GHz network from 40MHz to 20MHz and speeds went up to usual 80/80Mbps. Package loss also is under control now at 0.03%.

I changed a bunch of IPv6 settings on the last try as well, so I share them in attachments as well as I'm not sure maybe it was what helped (I'm too happy to have good connection to experiment further 😀)
