IPv4 is not much better:

hotel side issues

comment:2 Changed 5 years ago by jdishongh@…

Hi Jen,
Thanks for the info. The hotel has turned off their 5Ghz radios and have made adjustments to the radios on the 2.4 band. I'm curious, have you seen improvement?

I do see an improvement, it's not 50% packet loss anymore and I'm even
able to attach files to my emails ;)
However it is a bit far from working well unfortunately ;(

Just ran ping test to the default gateway and google.com:

Wifi info from my mac attached (one screenshot, "wifi_tue_morning"
just has been taken, another one from the last night which I was not
able to attach in my first email).
