I have been using Mac systems for a while now and have never faced such problems with it before. I recently bought an eMac which is installed with MAC OS X 10.4.11 on it. I have a Linksys router through which the eMac access Internet. The eMac is connected to the router using ethernet cable. The problem I am facing is Network keeps dropping on eMac. This started to happen when I tried to update the operating system on my computer which I cancelled midway. I am not that much into networking and hence need your help in solving this issue. Any suggestions about the topic is more than welcome.
