How good or bad is the network card speed of the Lenovo IdeaPad Z580?

Joseph Monticciolo November 24, 2012

I’m looking to purchase a Lenovo IdeaPAd Z580. Everything seems to be good except for one thing, i.e. the network card. I saw a video review of this laptop on YouTube and the reviewer stated that the network card only downloads at a maximum rate of 100 MB/second instead of the usual standard of 1 GB/second.

Therefore myself question is if someone can confirm this. I did a search engine search, but didn’t find anything.

Thank you.

    The lenovo Z580 has a RJ45 port, meaning the maximum speed it can ever get is 100Mbits a second. I do not think that is much to worry about as most people's internet is nowhere near that speed. The only time where I would consider a Gigabit Ethernet port is if I am transferring large files over the network.

    The card listed for the Lenovo IdeaPad Z580 is the Intel Centrino Wireless N 2200. After checking this link:, it looks like a good quality card. Reported 300MB/s speed, bundled with other features mentioned in that link make it a good choice.

    The network card that is listed on Lenovo's website for the IdeaPad Z580 is the Intel Centrino Wireless N 2200. After a quick search, this page came up:
    It has reported speeds up to 300MB/s, which is great for a wireless card.
    When you consider the other feature listed on that link about the card, it's actually quite a good card.
