Improving IOT in the garage

The dumb AP in the garage is a nexx WT3020, minuscule "travel" router that happily runs OpenWRT. There was a problem with the most remote stations (esp8266 nodes with MongooseOS apps) "giving up" on coming back online, once they faced too many connections drops.

This mod:

Resulting in this:

brought the following improvements:
| Station | Signal before | Signal after | Improvement | |-------------------|---------------|--------------|-------------| | b8:27:eb:6f:cd:a3 | -58 | -56 | 3.4% | | 84:0d:8e:51:d1:47 | -68 | -56 | 17.6% | | dc:4f:22:95:39:7d | -76 | -70 | 7.9% | | cc:50:e3:b5:b3:38 | -84 | -76 | 9.5% | | 5c:cf:7f:02:66:98 | -70 | -60 | 14.3% | | 8c:aa:b5:06:1b:e9 | -64 | -62 | 3.1% | | 5c:cf:7f:11:ab:d9 | -74 | -60 | 18.9% | | cc:50:e3:b6:8e:ac | -100 | -86 | 14.0% | | 8c:aa:b5:05:55:a9 | -76 | -70 | 7.9% | | c8:2b:96:11:79:2f | -88 | -82 | 6.8% | | ec:fa:bc:6f:0c:a5 | -92 | -84 | 8.7% |

The stations further away had the best results. Which was the problem I was solving.
