I have a Dell Vostro 1500 laptop with Vista Business SP2 + all updates. My ADSL modem is a Netgear DG834G wireless broadband router. Anti-malware: PrivateFirewall 7.0 + Avast! AV. Browser: Firefox 3.5.9
This combination works well, IF I remember to switch on the router before the laptop boots up. If I switch the router on afterwards, or if the router is switched off and back on, or when the laptop comes back from hibernation - it "can't find" the wired internet connection. No error messages, just failure to connect to the web or read email or even ping a site from the command prompt.
This is not such a big deal because if I switch on the wireless option on the laptop, and manually connect to the router the connection can be made, and sometimes after a while I find that the wired connection has been re-established. As a rule I prefer to use the wired connection - I think it is a bit faster than the wireless. But mostly I just want to know what/why/how etc. for my own education.
I have tried the Windows network diagnostics and it always comes back with the message that it can't solve the problem. Reboot: problem solved.
So I have two questions:
1. Why doesn't the laptop become aware of the router when it is switched on?
2. Is there a manual way to reconnect, like the manual "Connect to" option for wireless?
Thanks for advice.
