I owe a Dell Inspiron 530 with the Dynex wireless G Router at home. I know everything about the router since I’m online always. My wife too has a Dell Laptop when she also connects to the internet via the router. If one of us tries to log on to the internet after being logged off for some time, Explorer tells that there is no connection available. I then have to unplug the router and the modem from the main power supply, wait for a few seconds, then plug them back in. We can then access to the internet. This takes place daily. If I bypass the router and plug the cable directly into the tower there is never a problem occurring. I thought that it was my original router's problem but the problem still continues with the Dynex which I recently purchased. This is also a brand new computer but the problem has taken place with my last one as well the new one?
