Internet keeps dropping
Hi,
I am running my iMac with OS X Yosemite and have an Airport Extreme with 3 Airport Expresses around the house to boost signal. My internet provider is Frontier. Their modem is directly plugged into my Airport Extreme. Lots of time during the day the internet on my iMac drops out. I still have bars but pages fail to load or email fails to download. In order to get this to work I have to go into Airport Utilities and restart the system, which fixes it for a little bit and then it drops again.
The airport extreme is running version 7.7.3.
This is getting really annoying. Can anyone help me out?
Thanks,
Victor
