I have a Cat6a ethernet cable and TP-LINK Gigabit PCI Network card on Windows-7 64 bit OS Asus M2N32 SLI wireless edition Motherboard.
My router is a old 10/100 Linksys 54mbps.
Do I need 10/100/1000 upgrade router? If so, what do you recommend?
If you want the network to operate internally at gigabit speed, then yes you would need a compatible router. If you are not transferring files over your network, and your Internet speed is not over 100Mbps you can use what you have.
If you do decide to upgrade, take a look at the ASUS RT-N56U.
Thank you very much, RealBeast. So, I cannot improve the internet speed, I understand. With above mentioned setup (WIRED instead of wireless 802.11 g, and gigabit network card), do I improve INTERNET SPEED somewhat?
