Check LAN Setting
STEP 1: Click on the Start Button and type in "network and sharing" in the search box. Click on the search result.
STEP 2: Click Change adapter settings.
STEP 3: Right-click Local Area Connection and verify it is enabled. If it is not enabled, click Enable. Once it is enabled, right-click and choose Properties.
STEP 4: Click Configure.
STEP 5: Click the Advanced tab. There should be a Property box on the left-hand side. Select "Speed & Duplex", "Link Speed", "Media Type", "Connection Type", or the similar box on the left-hand side. This name can vary by adapter manufacturer, so each computer will be different.
Once the item under the "Property" box is selected, change the selection in the "Value" drop-down list.
- For TTU residence halls, change it to 10Base-T Full Duplex, 10Mbps Full Duplex, 10M_FULL, 10 Mb Full or similar.
- For any other on-campus connections, change it to 100Base-T Full Duplex, 100Mbps Full Duplex, 100M_FULL or similar.
Again, the options on this screen can vary by manufacturer. The "Value" field may read "AutoSelect" or "AutoSense" when first selected. Once this has been set, click OK. If you changed the setting, try accessing the Internet again (by accessing the Web, etc.) to see if that fixed the problem. You may have to try several settings to see which one works best.
If you change this setting it may affect your connection in other locations! For instance, if the computer is a laptop and you take it off campus you may have to set this option back to its default settings.
STEP 6: Right-click Local Area Connection again and click Properties.
STEP 7: Uncheck the box next to Internet Protocol Version 6 (TCP/IPv6).
STEP 8: Click Internet Protocol (TCP/IP) 4 (TCP/IPv4) to highlight it, and then click Properties.
STEP 9: Verify the options shown below are selected, then click the Advanced button.
- Obtain an IP address automatically
- Obtain DNS server address automatically
STEP 10: Verify that DHCP is enabled and Automatic metric is checked.
STEP 11: Verify that the settings under the DNS tab match those in the screen shot below.
STEP 12: Ensure that the settings under the WINS tab match those in the screen shot below:
STEP 13: Once all the above settings are correct, click OK until you are back at the Network Connections screen in the Control Panel. Close these windows until you are back at the Desktop.
If you changed any settings, try connecting to the network again (by accessing the Web, etc.) to see if that fixed the problem. If it didn't fix the problem, try using the Command Prompt to release and renew the DHCP lease if the connection still isn't working.
Release/Renew IP Address
STEP 1: Click the Start button and type in cmd in the search box.
STEP 2: Right-click on the search result and select Run as administrator.
STEP 3: Type ipconfig at the Command Prompt and press Enter. This will show the current IP address if there is one. Valid TTU IP addresses fall in the following ranges:
- 184.108.40.206 - 220.127.116.11
- 18.104.22.168 - 22.214.171.124
Even if address appears valid, try to release and renew it.
STEP 4: Next, type ipconfig /release *Con* at the Command Prompt and press Enter.
This will release the current IP address, if there is one.
STEP 5: Now, type ipconfig /renew at the Command Prompt and press Enter.
Your computer should obtain a new IP address. Compare this new IP address against the one noted earlier.
STEP 7: Try connecting to the network again (by accessing the Web, etc.) to see if release/renew fixed the problem.
Check QoS Setting
STEP 1: Go back to the Properties screen of your Local Area Connection. View the settings for the QoS Packet Scheduler and make note of them.
STEP 2: In the following screen, the QoS Packet Scheduler is enabled (checked). If yours is checked, try disabling it by unchecking it and clicking OK.
STEP 3: Go back into the network adapter properties and access the Advanced tab. There will, in many cases, be a setting that is something along the lines of "802.1p support" or "802.1p scheduler". Highlight this option and make sure the field to the right reads Disabled or something similar.
