All day today I’ve had crap wifi here. I’ve gone from 27Mbps down to 1mbps, even 0.1mbps. Moved the laptop to within 4 feet of the modem – same result. D’s laptop was getting 27Mbps. Then I remembered I had installed Notifyr last night.
Removed it, rebooted.
Sorted.
Notifyr. Avoid.
Phew! Thanks for the warning! I just installed it, too — removing it now.
