Just looking around me there are 45 wireless SSIDs, crazy interference and nothing but crap flying around my airspace. Half the time I can see people's bluetooth devices wide open in nearby houses as well.
Add to that the impending 9000 useless little devices that will be broken and this is the RF equivalent of space debris. It's got to the point I can barely keep a WiFi connection up for more than a few minutes already. Even on my 4G connection I'm lucky to get 4mbits due to the contention locally. I can upload at 40mbits though which is crazy
So literally last weekend I cabled my house with 5 runs of 100 meg ethernet and a couple of long patch leads in the living room and stuffed in a cheap 8 port netgear switch from ebay. Plugged the whole thing into my router and turned off the WiFi entirely just using it as a switch + NAT combo.
I can now transfer files between my desktop and laptop at 10Mbytes/second rather than 500k/second with dropouts. It is simply bliss. Even my wife is no longer annoyed about the prospect of dangling wires because stuff is working again.
It has got to the point that I'd rather have a broken CAT5 plug that falls out every 5 minutes than WiFi. I really don't know how all this tech is going to work when there is so much contention and noise already. I think it will just contribute to the pain.
