Is the router setup per our forum sticky? Latest firmware, default settings and WPA?
I have a Dell XPS as the main computer with Vista. I also have a cheap Compaq with XP and a brand new Toshiba laptop with Vista. I have Cox Cable internet with a Scientific Atlanta 2100 modem and a Dlink DI-614+ router. The Dell is hardlined to the router and the Compaq and laptop are wireless.
In the last few months the computers have started to lose their internet connections after being on for a period of time. In the case of the Compaq, you might only be on line for 5 minutes and you can no longer make a connection (the green connection bar goes slow and finally stops, usually befor you get half way connected). In the case of the Dell, you might be on an hour or two before the same thing happens. The laptop seems to be more like the Compaq, being able to make connections for only minutes (instead of hours) before being unable to make another connection.
Also, about the same time this started, I have gotten infrequent (usually 3-4 times per month) blue screens with a NETIO.sys error. Don't know if it is related, but since NETIO.sys has to do with the network input/output, I wonder if it might.
RE the blue screen, dell support tried an MS update, but I already had it. Their next solution was to reload the Windows operating system, which I am trying to avoid and so have not done that yet.
RE the intermittent email connection, Cox had me bypass the router and just use the modem to the Dell. Still had the problem so I assume the problem is not the router. They said since the signal was getting to the modem, it was not a Cox problem (the modem was provided by cox).
A computer guy I know said (without seeing it) that it could be the network card on the Dell motherboard. I tried to update the network driver, but I already had the best/latest driver.
Any ideas or suggestions as to what might be the problem? The modem, the Dell hardware, or the Dell MS Vista software? Any ideas on what to do next? Am I correct in assuming the problem is not with the Compaq or the laptop? Should I try a different modem? Any help would be appreciated. Thanks.
