Can not connect to my wireless network Insipron 1420

Hey Everybody.... I'm not that computer savy.. but having trouble connecting wirelessly to the internet from my Inspiron 1420. I can see my routernetwork and the signal strength is good, but when I try to connect it says that it cannot connect. When I press connect diagnose problem it quickly opens a small window stating that windows could not connect to "Kat-wifi" (my network. I have tried rebooting the computer as well as rebooting the router by uplugging and waiting the 30 sec to 1 min and then retrying but to no avail.  When I connect the computer to an ethernet cable I AM able to connect to the interent. I even atempted to manually run a test with the wireless and it passed everything except the PING test. it stated NO RESPONSE DHCP SERVER. I tried then to go to the screen of Wireless Network Conenction Properties and checked the IP Version 4 (TCP/IPv4 and both the obtain IP address and Obtain DNS server automatically are already on. I am running out of ideas.. PLEASE HELP.... I will place a copy of the cmd ipconfig /all file that I ran so hope it helps.. Thanks in advance for any comments and any help out there..

The thing is also that other wireless devices are able to connect to the internet and the laptop used to be able to connect to the internet but now it can't...grrrrr

Kittykat78,

 

Check your AVG Firewall settings, it may be blocking. This is for printers but gets you to the firewall settings. Allow Wireless Printer Blocked by AVG 8.0 Firewall

 

To setup the router(if needed)

 

How to login to your wireless router and use these Recommended Wireless Router Settings I use channel 11. I would make a new SSID to make connecting easier.

 

Setting up/Troubleshooting a Wireless Network has pictures that you can follow so it makes changing it easier.
