    How to pick and optimize your home router


    By Robert Vamosi

    Staying safe on the Internet requires the combined forces of a router-based firewall, security software, regular updates, and a secure browser.

    In this column, I provide recommendations and tips on how to pick the right router and how to set it up for maximum protection from malicious Web sites.

    The full text of this column is posted at WindowsSecrets.com/2010/07/15/06 (paid content, opens in a new window/tab).

    Columnists typically cannot reply to comments here, but do incorporate the best tips into future columns.

    The SW piece of router support all very helpful. What I discovered was that the HW piece is more complex. Let me explain. I purchased a dual band Cisco Linksys router WRT610N and a couple of WET610N Wireless Bridges which I was able to configure as I had intended:
    1. 2.4Ghz band for all my legacy WiFi devices
    2. 5 Ghz for my Media Hub- TV connection with the Wireless Bridges

    What I discovered was fine performance for all my legacy devices and lousy performance for the 5 Ghz band devices.(I eventually reconnected on 802.11g 2.4Ghz to get 'best' performance.)

    Researching I discovered that the actual power output for the 5Ghz band as specified in the Linksys spec
    UNII-1 (5150-5250GHz)
    802.11a: Max. 14.0dBm @ All rate
    Wireless-N 20MHz: Max. 11.5dBm @ All rate
    Wireless-N 40MHz: Max. 12.0dBm @ All rate
    UNII-3 (5725-5850GHz)
    802.11a: Max. 17.5dBm @ High rate
    802.11a: Max. 20.0dBm @ Low rate
    Wireless-N 20MHz: Max. 17.5dBm @ High rate
    Wireless-N 20MHz: Max. 20.0dBm @ Low rate
    Wireless-N 40MHz: Max. 17.5dBm @ High rate
    Wireless-N 40MHz: Max. 21.0dBm @ Low rate

    I don't believe the output power was performing to spec but even so the combo of transmit power shortfall (UNI-1) and receive sensitivity differences made a totally unusable system for me.

    Worse, I discovered (now that I am looking for the highest power 5ghz solution to replace this set-up I have) that the new Valet line of products don't even a publish TX/RX performance specs at all.

    This ought to be a huge warning for all potential 5Ghz customers- output power, MIMO functionality, receive sensitivity.

    FWIW
