I have two macs that I use using a linksys router. I have an emac 10.4.11 and an ibook running on the same. I use firefox as my browser and mac mail. My ISP is a local satellite company and it's been working great til about 4 days ago. Sometimes everything loads fine and very fast. Other times, everything hangs. Might take 2 min. and up to 5 min. to load. I only have one website open at a time and my mail app. Seems like I'm having to re-start the computer 2-3 times a day otherwise I'm dropped out of my wireless connection. Why is it doing this? Does this sound like a router problem or ISP connection problem??
