I bought a used Compaq Presario CQ56 recently. It works well except that the wifi doesn’t work everywhere. It will work on a public wifi, such as AT&T;, where you connect to the wifi through the computer, and then agree to the terms on the browser.
It will not work, however, on any other type of wifi, such as a home network, and it will also not work on an ethernet connection. I’ve checked the password on the network, so I know it’s not that.
I think it has something to do with the public network access, but am not sure. What can I do to make it work?
Thanks in advance.
If it won’t work n the cat-5/ethernet connection either then there are a possibly a couple of things to check first… Presumably you are referring to cat-5/ethernet connection with “your” home router?
Look in Device Manager and see if there are any yellow exclamation marks showing in the Network Adapters “branch”. If so then start by resolving those…
This link may help re’ Device Manager…

That you can connect to other wifi (public) networks does suggest that the wifi adapter is OK; though possibly the cat-5/ethernet one isn’t. It may be the cat-5/ethernet adapter is simply “switched off” (disabled) on the laptop? Is there an icon in the system tray (bottom right) showing for the cat-5 adapter? There ought to be one for cat-5 and also the wifi adapter. If either is disabled/not working correctly often it will show as such. But again as you appear able to use wifi OK elsewhere, that adapter ought to show as OK in those locations, but not so “at home”.
Check Device Manager and see what may or may not be showing there.
Reboot the router and then see if you can connect to it via cat-5. IF not then “reset” the router. This will restore/reset the router setting to the default settings – as delivered.
What make/model router do you have?
