I also use Zone Alarm and AVG and frequently check for spyware various ways . Turning off the firewall completely does not help BTW.
I have a network with the following components:
Toshiba Satellite 1005-S157 laptop w/XP
DLink DFE 690TXD NIC for laptop
Dlink DI 524 wireless router (using wired connections only)
Speedstream 5100 modem
Win 98 desktop with Compaq NC3121 fast ethernet NIC
After turning on my computers, sometimes I am able to get internet access and sometimes not. I can power cycle the modem and/or router and get it (sometimes this takes several tries but ultimately I can get on). The laptop occasionally will tell me a LAN connection is unplugged (NIC lights go out) and then a few seconds later lights come on internet is restored.
I?ve tried a different router (new) and a different NIC (new) for the laptop but get the same symptoms. I?ve tried setting up the network again also but still no changes. Sometimes when I turn on a PC I will get an internet connection and sometimes not.
I generally get better luck with the laptop than the desktop. I also can usually get immediate internet connection by plugging a computer directly into the modem and leaving out the router (again, the laptop does a little better than the desktop). I can get what I need but it?s annoying and I feel like I?m either being stupid or being messed with by the cyber gods.
The only common item seems to be the modem.
Any suggestions would be appreciated.
