Help! Network connectivity problem
 

My wife's HP PC is finally toast. According to the diagnostics, the wireless adapter is fried. I bought her a Macbook Pro and I'm trying to migrate the stuff on her PC to the Mac. The Mac wants to be on the same network as the PC to do this, but I can't connect to our wifi network with the PC. I can only get on line with ethernet.
Is there some way to get on the wifi network while connected to the router via ethernet? It's a Linksys E1000 router.

Sure, if you connect the HP to an Ethernet port on the back of the router, your on the same network as the wireless clients.

You have several options: https://support.apple.com/en-us/HT201553

I would go for the direct connect route wherein you bypass your router by directly connecting the two systems together via a network cable.

edit 2: HardDrive is correct. If you plug the HP into the router and your mac is connected to wifi on that router then you are on the same network.

If run into trouble, you could always connect the HP via Ethernet, the dump all the files to the cloud via Dropbox, Google drive, etc. Then just drag them down into the Mac. It will chew up bandwidth, but so what? Let it run overnight.

As stated, connect direct via ethernet to the router or directly connect the two machines.

For the most part these days Ethernet ports are auto sensing and crossover cables for direct connections are no longer required.

The mac can't find it on the network, that's why I thought it wasn't there.
Wife says she's going to go the route suggested above and do some housecleaning. She doesn't want a lot of the crap on the PC.

I think you have to expose the PC on the internal network, or share the drive or something.

There are two ways to get the new computer connected. First is to go into your wireless router and get the following: network name, type of encryption, encryption key (check to see if it is case sensitive) and make sure the router is not restricted as to MAC addresses.
Enter this info in the setup section of the new computer wireless network properties and make sure you are close by to the router.

Second method is to go into the router and turn on "broadcast" so that the router is looking for clients. Use the network properties in the new computer so it "looks" for close by networks and yours should show up. Again make sure you are close to the network router.

You can test this with your smart phone as it should be able to connect to the wireless router and if you can do that then the new computer should be able to.

As already noted I would recommend using a hard wire to connect as it is safer, faster and more secure. On the old computer, go into the properties of the hard drive and make it shared and once the computers are connected you can attach the drives and just copy any documents/pictures/files needed. Note you will not be able to "copy" any applications.
