Often when a user complains the internet is down, what’s really happening is that DNS isn’t working. There are a few simple tools and procedures to diagnose and repair DNS problems.
for example look at this motherboard.…You'll see that this motherboard has a built in NIC.…It even has a cute little antenna here…so this is all built in and it has drivers…that come with the drivers just for the motherboard itself.…You'll even run into stuff like this…for example this is just a USB to 802.11 wireless NIC…so I'd just plug that in and I get a wireless that way.…My laptop here in fact gosh it'd be hard pressed…to find a laptop that doesn't have…built in wireless anymore.…
What's interesting on laptops is in almost all cases…the antenna for the wireless network card…is actually in the monitor itself.…That's important for the A plus.…And certainly last but not least…is all of our mobile devices, all of our tablets,…all of our smart phones all have 802.11 network cards…built into them and the antenna (laughing)…is pretty much the entire case on most of these things…so you're always going to have a wireless access point…and then you're always going to have a NIC.…
The wireless access point will be configured…
