    My ancient HP desktop connects to the network via wired connection. My laptop connects wirelessly (usually). Both have very strong signals from the router and the desktop connects to the internet just like always, but the laptop isn't getting the internet signal. The laptop is an Acer Aspire 5534 (Costco special) and the router is a Linksys Simultaneous Dual Band N-type. The only real significant thing that was done on the laptop was to install Adobe Shockwave Player with Norton Scan. I already have McAfee on the laptop tho, so I uninstalled the Norton. I'm going to do a system restore in a moment...any other suggestions would really be appreciated!

    BTW, the laptop would occasionally seem to disconnect itself from the network and I would have to completely shut down the network (hard restart) and all computers to reset. This always worked before, but now it isn't. Like I said, I have excellent wireless connectivity, but the internet isn't there, just on the laptop. Even if I go wired with it!

    I've narrowed it down to a freakin firewall issue with McAfee. When I turn the firewall off, I get access to the internet. I restored the firewall settings to default and everything seems "normal" again. But why would my firewall start to do this. It seems to randomly disconnect my laptop from the internet (not the network).

    Because that's one of the things they like to do from time to time. Probably means it's corrupted, so best to uninstall it and run both the Norton and McAfee Removal Tools before reinstalling either.
