Q: Very slow internet connection on MBP mid 2010
Hello there,
I've got a MBP mid 2010 running ML 10.8.2. Model n° A1286.
Since a few weeks my internet connection with my wireless router AND with the ethernet port has become extremely slow.
The Wi-Fi does work, the ethernet as well, since we've got more computer here at home and there are no problems at all with those devices... So the problem is probably my mac.
Now I don't have any clue about this. It's too rare that both my Wi-Fi network card and my ethernet card are broken.
So I thought maybe there's something in the system preferences that's gone wrong.
Thanks in advance...
MacBook Pro, OS X Mountain Lion (10.8.2)

First contact your ISP. You need to confirm that the issue is not on their end.
Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.

Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.
