We have been having trouble with our Airport Express. It is
working very slow (takes about 1 min. or longer to load a page).
The internet works fine when we plug it directly into the
computer. It was working fine a month ago but now it won’t. I
have tried resetting it and unplugging everything. We have had
problems with this Express before (we had to unplug it fairly often
just to get our computers to connect to it).
products, often requiring more resets than a simple device like this
should. So, I would absolutely recommend resetting the Airport
Express back to factory defaults (pressing the reset button for about
15 seconds until the light blinks 4 times), and reconfiguring it with
Airport Setup Assistant. If you have already done that, you might try
switching cables out. If that doesn’t work, and if it’s under
warranty, please call Apple to get a new one. If it’s out of
warranty, might as well buy a brand new, freaky-fast Airport Extreme!
