Would it shock anyone to know I actually did this reboot to a malfunctioning public Wifi base station recently and it worked?
I had a client moving into a new commercial location where the local cable company (Shaw) has one of their public Wi-Fi terminals installed.
They did not have their own network connection yet (booked for a few days later) so we just joined their computer to the public network but it was horrible. The connection showed moderate to high packet loss which was strange because the base station was in the roof a few feet away. Even doing a ping test to first hop (the base station) was showing the packet loss problem. Increasing the packet size on the ping tests showed the problem was got worse as you increased the packets so anything that wanted a sustained download and not small little transactions was suffering worse effects.
So I went into the back, found the power injector for the base station and cut the power. Plugged it back in, and after the reboot it was working well. No more packet loss, and a usable connection.
Maybe Shaw needs to update the firmware on these Cisco base stations they are using.
