Network Connection dropping/reconnecting. "DNS Lookup Failed"

Hi, I've been having wireless network issues ever since we purchased a new router (Netgear n300) probably about one year ago. My laptop has no issues with other wifi connections, but when I am connected at home, the connection continually drops and reconnects. It usually disconnects for 10-15 seconds, and then reconnects. This happens constantly while I am at the house.

When I troubleshoot the connection, the message "Default Gateway not available" often pops up. When the connection drops while a webpage is loading, the browser tells me that "The DNS lookup failed". Also, our home network connection is named "Home-FORCE", but on my laptop the name shows up as "Home-FORCE 2".

Has anybody seen or had this issue before? I am wondering if the problem is with the settings on my laptop, or if I made an error while setting up the wireless router.

There are several other laptops in my house that connect just fine, and my smartphone has no issues with this connection. However, when my laptop is connected to wifi, other laptops in the house begin having the same issues.

Any help is much appreciated, and I will gladly provide any additional information that I can.

Have you done a ipconfig /release and then ipconfig /renew at a command prompt? It does sound like some setting(s) are amiss on the laptop. Go into control panel on the laptop that isn't working and go to the networking properties and check to see if get DNS automatically is selected. I will post exactly how to do that when I get home soon

Also have a pretty bad speaker setup which is a klipsch promedia 5.1 surround speaker setup with huge subwoofer and lg blu ray player/writer. Also a hp officejet pro 8600 plus wireless all in one and a logitech s7500 webcam.
I have tried ipconfig/release and ipconfig/renew in the past, and it hasn't seemed to change anything. I just tried it again now. I also went into the settings for Internet Protocol Version 4 and selected "Obtain DNS Server Automatically". It had been set on 8.8.4.4 / 8.8.8.8.

I will reboot the computer and let you know if anything changes today. Thanks for the quick response!

Have you tried updating the firmware on this router? Be sure and check the routers version number, the actual model number also matters, Netgear N300 isn't the model number, it's WNR2000, details matter. :)

What is the actual model number of your router and have you tried doing what Chev mentioned above?
