Well... I'm brand new to broadband, so any answers will have to be at the noob level. I have cable internet access through Time Warner. They're using a Motorolla cable modem, and I installed a NetGear router. I also use the free version of Zone Alarm. I've had the broadband service for about two weeks, and everything has been great. It was incredibly fast up until last night. Wednesday night I fired up Kazza Lite, and set it up to download some files, along with sharing a bunch of files that I had. Things were downloading at a pretty good rate. Thursday morning I noticed that some of the larger files hadn't finished yet, so I left Kazza up while I was at work. When I got home, I shut down Kazza and attempted to surf the web normally. I couldn't get ANYWHERE. Every page took five minutes to load, if it would load at all. I'm talking DOS attack slow. I removed my router, no difference. I tested my NIC, it tested fine. I called Time Warner, they said the line looked fine, "maybe it's just net congestion..." Yeah right. I shut down Zone Alarm, no difference. Zone Alarm doesn't seem to be reporting any abnormal behavior. So... What else can I check for? How do I check to see if someone is attacking me, if that's even possible since I have the router and Zone Alarm. If you don't think it's an attack, what are the symptoms of a failing modem, or NIC? Do they simply fail, or do they slow WAY down like this? By the way... my dial-up access works just fine. Sorry about the length... thanks for the help.
