Slow Wifi with just one laptop?
I have 3 laptops, 1 destop, and xbox.

However, only my laptop with wifi is very slow. it just happened all of a sudden. however, it is fast with an Ethernet cable plugged in. This just happened last night. The other 2 laptops run fast with wifi .. Help?

can we see an xirrus screen shot - from the faulty PC and one of the working PCs
------------------------------------------------------------------------
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 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.

http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

{If the above link does not work heres another link http://www.pcworld.com/downloads/fil.../download.html}

Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need will need to haveNET Framework installed for the WiFi Inspector to function.

Run the program

A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus...-1-RevB-6.aspx

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)

To post a screen shot of the active window.
1) 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.
OR
2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
Full details are available here http://library.techguy.org/wiki/TSG_...g_a_Screenshot

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

If you are using the Mac OS then use http://www.istumbler.net/ or
if you want to optimise base station position and signal strength / dead spots use
http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

-71 is too low for a robust signal you need to get above -70 - green
you may need to move the router, a few feet can make a difference , or if possible move the aerials around see if you can get a better signal

you also have a lot of signals on channel 6 - so that maybe interference - log into the router and change the wireless channel to use 1 or 11
