  Hi Reinette,

  Might be of interest:

Happened on site B, with high throughput (280-340k/s). So, it's happening w/ both, fast
and slow conn speed.

Yes, I noticed and had a look into the compat-wireless scripts but preferred to do 
it manually. Thank you for your explanation.

Cheers,

                Nils
