    I have this weird problemÂ… if I sit right next to my rooter, I get around 5-6 Mbps. If I go in my room, just a few feet away, I get Limited connection or no connectivity at all...

    The signal is always show as strong, in both case.

    I was in an hotel the other day and everything worked fine.

    I tried changing the chan.

    Any ideas?

    an we see an xirrus screen shot please
    1) when you are next to the router and working
    2) when in the other room

    Do you have any other wireless devices working with the router ?

    ------------------------------------------------------------------------
    Run Xirrus Wi-Fi Inspector
    Download and install

    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file to the faulty PC and install the program.
    You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

    If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply

    http://go.pardot.com/l/66982/2015-01-26/2361i
    enter you details
    Download this file "DOWNLOAD WI-FI INSPECTOR Vx.xx "
    ( the site now appears to allow webbased emails like gmail, hotmail, outlook and yahoo now )

    There is also a xirrus gadget, But that does not have all the fuctionality "DOWNLOAD GADGET Vx.xx

    Alternative links - Use the links below


    http://www.softpedia.com/progDownload/Xirrus-Wi-Fi-Monitor-Download-99109.html

    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You will need to have NET Framework installed for the WiFi Inspector to function.
    On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

    Run the program

    A user guide is available here
    http://www.xirrus.com/cdn/pdf/xirruswifiinspectorguide1-2-0

    post a screen shot of the program running.
    if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information.

    post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)


    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
    note: the signal level is a negative number, so for example -88 is worst and -40 is better

    To post a screen shot of the active window.

    Windows XP
    Hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.

    Vista or Windows 7
    you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool
    http://www.bleepingcomputer.com/tutorials/how-to-use-the-windows-snipping-tool/

    Windows 8
    you can use the snipping tool > Open Snipping Tool (From the Windows 8 Start Screen, type "snip" and press enter.
    >Press the Esc. key.
    >go back to your Windows 8 start screen - Swipe from left or press Window Button
    >Press Ctrl+PrntScr button to use Snipping Tool

    they both look fine
    and the signal hasnot gone below -70 which i expected - so should still be able to get a good connection

    i would suggest updating the wireless adapter driver

    Whats the make and model of the PC ?

    the adapter is a Ralink - so you should see the driver on the PC manufacturers website support pages for you laptop model

    Okay, that's a start!

    I have an HP Pavilion TouchSmart 15-n080ca, Model#: F5U88UA#ABL

    The RAlink is named as: "RaLink radio model RT3290" on the back of the laptop.

    I'll look on HP web site for a driver update

    Thanks for you help btw! Appricated that!

    Thanks for your answers!

    I tried what you recommend, with a few extra step:

    1- Installed the drivers for the adapter (same prob)
    2- Clean installation of windows (same prob)
    3- Re try solution 1 with the clean installation of windows (same prob)

    Same thing, as soon as I get a few feet away from the router, it’s super slow for 2-3min. then goes to limited connexion.

    Disable Bluetooth through device manager and see if it makes a difference.
