Wifi issues. It works fine then all of a sudden can't connect.

Hello, I've been having this issue recently. On my laptop, the wifi works fine, and then a little while later, it can't connect at all (it looks like it's connected, then disconnects, and then tries connect again, etc). All the other devices connected to the router is fine, only mine is the problem. I tried looking at device manager, the Intel Centrino Advanced-N 6235 is enabled, updated, and in the properties, it says that the device is working properly.

The problem does go away temporarily when I turn off the router, wait a little, and then turn it back on, but soon afterwards, I continue to have connecting issues.

Here's the info

1. Is this a wired or wireless connection issue?
Wireless

2. Who is your Internet Service Provider (ISP)?
Verizon

3. What type of Broadband connection are you using?
Fios

4. What is the exact Make and Model of your Modem, Router or Modem/Router Combo - Linksys, D-Link, Netgear, TP-LINK, etc.
Router: Actiontec? Not totally sure

5. What is the Name of the Anti-Virus, Security or Firewall Software installed from the problematic
Avast

Welcome to Seven Forums,

Thanks for using the basic requirements, all info provided were very helpful. Your Xirrus capture looks good, no issue there, however, I see that in your wireless connection you're using Public DNS, why not change the DNS'es to auto same as your LAN DNS Servers . . . . . . . . . . . : 192.168.1.1. You'll have to click on Obtain DNS address automatically....Please follow this Tutorial.

Also, it's best to use WPA2 with AES encryption for a better secured network, you're currently using WEP.

Change TCP/IP settings

I use OpenDNS, so that's why the DNS is public. I've been using that for a while now (year+) and have had no problems. I changed it back to auto, but no dice, I still can't connect

I tried using your suggestion for changing the network to a WPA2, but I couldn't connect. It said "The settings saved on this computer for this network do not match the requirements of this network"

Try refreshing your wireless profiles, delete all of the SSIDs then re-add yours with the proper pass-phrase.

Scanning your computer for any infections won't hurt. Download and install Free SuperAntiSpyware. remove all infections found and see if that helps.

No dice on either. I did find some infections though, but still not connecting

FWIW, I troubleshooted again, and here's what came up (again)

Alright, let's try something else....

Have you tried different browser's?

Check your browser(s) for any Proxy setting and remove if found.
Removing Proxy Settings By Browser - Charter

Do a test - restart your computer, continue tapping F8 and select Safe Mode with Networking, see if you're able to connect.

Another test - how is it when you're connected wired? Also, have you tried connecting to different Wi-Fi connections?
