Hi Celeste and welcome to WTT
Sorry to hear of the problems you are having with the Internet connection.
You have done a lot of the things that usually help solve the problem, but here's some extra suggestions to try.
1 flush out your DNS cache...here's the instruction.
press the enter key
you will need to run this from a command prompt (as you did for the other Ipconfig commands)..and as you know the space between the g and the/ is necessary, you may well get the same response as you got before for the other commands but its still worth trying again.
2 next try this instruction, exactly as it appears below, (still from a command prompt)
netsh int ip reset resetlog.txt
press the enter key
3 Next close down your machine wait 30 seconds with a blank black screen then restart it......see if your internet is back
4 If its still not working, then check that the WPA or other "password" needed for the encryption set up on your router is correct
5 The above instructions only take a minute or two to complete so are best done before we go to the next steps so now its time to check that the network adapter is working correctly and the drivers are Ok (present, in the right place and not corrupted) so now open :
Device Manager and expand "Network adapters" you should see your wireless adapter and your wired adapter....make sure there are no yellow flags (exclamation marks) or red crosses to be seen..if there are then you will need to reinstall/update drivers.
6 Finally power cycle your modem/router, ( Warn anyone who is on your network first!) make sure your computer is shut down and powered off (not in sleep or standby) switch off your modem/router/gateway wait 30 seconds, switch them back on and wait two minutes. Next restart your computer and try to connect.
7 Open your browser (internet Explorer) and try to connect to a webpage, if you get an error, press the F5 key, then press it again after 5 seconds, if you do not connect then look down the error page and run the Microsoft diagnostic.
Let us know how you go
