Linksys router speed problem solved

I was mystified at the painfully slow wifi I was getting at my mother’s house. She lives in Silicon Valley where decent speeds should be expected, but I was getting <1 kbps download on Weirder, the upload speed was 5-6 kbps. Via Google, this blog post explained the problem and solution, which is worse on Apple products. Changing one config setting increased the download more than 25x on my ipad.
