I had problems connecting to my wireless internet for extended periods of time with my lease expiring almost instantly. Nobody else in my house had trouble connecting, only me. Troubleshooting the connection only showed that the default gateway was not available and failed to allow me to connect despite "fixing" the problem.
I attempted the ipconfig/renew, netsh int ip reset reset.log, and netsh winsock reset catalog operations in cmd as an administrator to no avail. Finally, as a last resort, I reset my modem and that finally allowed me to connect although occasionally I would be kicked off the connection and have to restart the modem again. I would still like to know the problem and a possible solution since my friends seem to have a similar problem with their wireless internet.
Many thanks for taking the time to read through this long question!!

ipconfig/all before resetting the modem:

have you updated the driver ? - use the service tag number on the Dell PC label and use the support site to download the driver

lets see am xirrus screen shot when working and when not

------------------------------------------------------------------------
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/file_download/fid,77196-order,4/download.html}

Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need 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/Xirrus-Wi-Fi-inspectorguide-1-2-1-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_Posting_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/

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

Do you still have this problem? I see that you now apparently have the lease period set to an hour. If your lease expires at the end of the hour and you have to restart the system to regain an IP configuration the cause is likely a firewall configured to block the lease renewal.

If you mean the driver for my WLAN card, it was already updated at the time of the problem.

I've attached a screenshot of Xirrus while my connection is working; I may have to wait a bit until the connection dies on its own to get a screenshot for when it's not working.

Thank you for replying and for your patience!

Thank you for taking the time to reply! My lease was successfully renewed and my connection is fine right now.

Here is ipconfig/all at the time of my reply:
