I am also having a similar problem with my Cricket broadband. The problem is that if I have my cricket broadband going, and I step away from the computer for a little while and return, Cricket broadband will no longer let me surf the web or do anything online but it will still say "connected". I have to fight with it by disconnecting and reconnecting (often a few times in a row) or sometimes having to reboot to get it to behave. Sometimes the fighting takes several minutes, and it is really annoying. For some reason it is because of me being idle from my computer (10 minutes or longer) that causes this problem to happen. Firefox will not run (loads half way) neither will I.E. The funny thing is that Skype will still be online BUT NOT yahoo messenger. I have called Cricket customer service 5 times and the issue is unresolved. They pretty much told me now that they don't know why and there is nothing they can do to help. There is nothing wrong with my computer. i suspect that something is blocking me, but why only when I go idle? Can anyone help me though this? I don't think I can keep fighting forever, don't have the patience. I am wondering if T-mobile or Verizon has a better working broadband than this piece of crap. Maybe it is my firewall, I have Mcafee, but don't know where to find the pin in the haystack, maybe it's firefox, but I don't think so because I.E. also becomes unresponsive.
