I recently switched from a DSL to a cable broadband ISP and use the same Belkin wireless router at home. I had no issues for a couple weeks, but in the last few days, the internet speed on my Macbook Pro will seemingly come to a halt after a while. I don't experience the same problem on an older Powerbook. After some trial and error, I've found that the problem is temporarily fixed by switching the airport off and on. My ISP can't seem to offer any help with this problem. Does anyone know what steps I should take?
