It's one of those situations where people know a little and so feel they can ignore that, so they need an explanation as to why it's a bad idea, annoyingly.

I'm having my own problem; I thought I'd lob it in here in case any geeks have time to think about it. Recently got a new laptop, and it's all pretty swish apart from a wireless issue: on most wireless connections, I'll suffer random disconnects, and the usual error reported is that "the default gateway is not available". It usually takes resetting the connection to make it come back. It's better or worse with different routers: Forest's is particularly problematic, with a connection rarely lasting more than a minute. I discovered through some Googling that this problem is a bit notorious with Windows 7 (it happens across different makes of network adapter, but couldn't find any definite solutions. I've tried setting the IP address by hand, turning various functions off, and reinstalling the network adapter, but not of it has worked. So I thought I'd ask here if anyone has time to make a suggestion. No worries if not.
I'm on a Toshiba Satellite C660 and the adapter is a Realtek8188CE.
