Someone in my work environment is providing an ad-hoc wireless network called 'Free wireless internet'. I can connect to this network using my (firewalled, unix) laptop, but don't get a functional internet connection when I do this. I see numerous similar networks (sometimes 'Free wifi') when using my laptop at airports. Is this the result of a virus? If so, which one?
Why are my wireless routers flakey? I have a Comcast cable modem, which I use with a wireless router to create both wired and wireless networks. I have tried 3 (!) different wireless (802.11b/g, WEP) routers (Belkin F5D7230-4, Netgear WGR614, Apple Airport Extreme). In each case, the wired connection has been stable, but the wireless signal periodically disappears without warning. It's not just an interference issue, because power-cycling the router fixes it immediately. [more inside]
I want to connect my (not-internet-connected) ethernet network to an existing 802.11g network. What hardware do I need? [more inside]
