This is happening 100m in the next household, and having a human (water bag) standing between the two households improves the situation. So on each commercial break, the local wifi improves because the humans next door go to the washroom. This means that the wifi speed/power selection gets all all confused, several times per minute. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | IoT architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [ --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEbsyLEzg/qUTA43uogItw+93Q3WUFAmEPH1oACgkQgItw+93Q 3WXceAgAj4ukhX3pQkT8tYbq+q1oOEAo/K2KOmB9qxZj/BKiICI68uOc2/+malYp 9DR8kU81/C2T+nW73TrJ0bJLUiMQFWktH59kWpmE7wM2ak1p9b9dJdfL0PqsCNcX F2JdN4aLJRukhbzIMnFkv+OWl/tsb32vYLzDC60ueGQF72mj1Dz/DZEBjriouHr+ sV1ixQ3OTgZVj3BXt4oHvdvQXz2aUmefQ3dcp7TC+OqW89TIeLL6NKP6RQqKth1T ZkytU9iJn6Vd+g1564HYMVNr0mdhKPDNQaaIgeZjMc9/SMSy7m1jxzjfYrpmbyHk X1QY3oJU7F150qgUCF2atNz/NnO3Tg== =PW/z -----END PGP SIGNATURE----- --=-=-=--
