Marriott wifi blocking

Mon Oct 6 19:01:06 UTC 2014

I live in a condo.  I have a WLAN set up.  More people move in and start 
setting up WLANs and the collective noise of those WLANs starts to 
impact the performance of my WLAN.  Just because I was there first 
doesn't mean I have any right to start de-authing the newcomers.  I 
don't see how Marriott has any additional rights to de-auth personal 
hotspots than I do to de-auth my neighbours.

After all, if you fire up your personal AP, with a non-colliding SSID, and start downloading multi-GB files, that’s bound to impact[1] anything else using that channel. While there are at least a few non-overlapping channels on most wifi networks, if Marriott(’s third party network operators) had any sense they likely would have situated their APs and channels to provide the most range with the least amount of frequency overlap. Now here your personal AP on one of those channels consuming enough of its bandwidth to significantly degrade performance for anyone else, and they may not have access to (or usable signal strength or bandwidth on) another channel from their hotel room.

This may be a stickier case, as no one user is causing the issue but one could make the case that, in aggregate, they are very much interfering with existing operations.
