Other Fixes

The following steps have shown to stabilize connections to OSU_Secure in Windows:

  1. Wireless Certificates:
    1. While connected to OSU_Access(needs to be this network), using Internet Explorer, go to https://csacs2.nws.oregonstate.edu/
    2. Once here, you will be redirected to a Cisco authentication page. You will not need to log in. Just going to this site downloads a certificate you may be missing.
    3. Also go to this address: https://csacs1.nws.oregonstate.edu/ to check for the same certificate, if you didn't receive it from the first link. You won't know if you actually have the certificate or not, but using both addresses gives you a better chance of getting it.
    4. Once you have gone to each, and loaded each page, restart your computer.
    5. Check connectivity now.
  2. Power Properties:
    1. Go to or search for Control Panel.
    2. Click Network and Internet, then Network and Sharing Center.
    3. On the left side of the window, click Change adapter settings.
    4. Right click on your Wireless Adapter(usually Wifi, and connected to a network). Click Properties.
    5. In the new window under the Networking tab, select configure under your wireless adapter name. f. In the new window under the Power Management tab, make sure the box next to "Allow the computer to turn off this device to save power" is unchecked.
  3. Complete Internet Repair Tool:   This software could potentially fix unknown or unseen issues with your connection, working with the software on your computer.
    1. Complete Internet Repair Tool can be found at the author's website here: http://www.rizonesoft.com/complete-internet-repair/
    2. Scroll down the page until you see the Complete Internet Repair (Build 2103), being cautious not to click on supporting ads.
    3. Run this software when connected to OSU_Secure(limited or connected).
    4. Restart your computer and check connectivity now.
  4. Re-Install Your Wireless Adapter Drivers: (assuming you can get a Internet connection elsewhere)
    1. Find the make and model of the laptop, and the wireless adapter make and model if possible.
    2. b. Search the laptop manufacturer's website first for the driver, then the manufacturer's site for the adapter if needed.
