I bought a macbook and ever since then my net connection SUCKS. Even plugged into an ethernet cable I lose connection. Sometimes pages just won't load and says 'not found' in safari (pages like google.com). Other times it says I'm not connected to the internet. Apple support said there was a problem with this router and to upgrade the firmware, I did. I have the WRT54G v. 6 model. I've reset everything (cable modem, Linksys router, vonage box). Nothing works. What can I do? This is driving me insane; I can't connect to the f***king internet half the day.
