Try the following troubleshooting steps which may resolve the issue:
1. Boot the computer in Safe Mode with Networking. To boot the computer in Safe Mode with Networking, please switch on the computer and start tapping the F8 key which would take you to Advanced Boot Option screen. Using the up and down arrow key, select Safe Mode with Networking to boot the computer into Safe Mode with Networking.
2. Check the IP address of the wireless connection. Click on Start and type cmd, on the command prompt screen type ipconfig and hit enter. Check for the IP address starting with 192.168….
3. If you get an IP address starting with 192….ping www.dell.com and check if packets are received. Note down the IP address of www.dell.com
4. Browse to dell.com with the IP address. If the Dell webpage opens, there is an issue with the DNS settings.
5. Connect the system to the modem directly and check if the system is able to go online. Howver, If the system is not able to go online power cycle the modem and the router.
Meanwhile, if the wireless LED is off (refer to the picture below), turn it on by using the Fn+ F2 keys on the keyboard.
Please reply with the results.

When i do the ipconfig it brings up an ethernet adapter local area connection that says media state disconnected and a wireless network connection with media state disconnected also.
The error, media disconnected for Ethernet connection may be due to the reason that the Ethernet cable is not connected to the system.
As for the media disconnected error on wireless, may be due to the wireless card not getting detected in BIOS. Check the status of wireless in BIOS. To go to BIOS, shut down the system and once you restart keep tapping F2 key, on the BIOS screen use the Shift +P key to go to page no.7. If it is off turn it On. (Refer to the snapshot below)
Also, would recommend you to connect the Ethernet cable to the system and check if the internet works fine on a wired connection. If no, I would suggest you to power cycle the modem and router.
If you are able to connect to the internet on wired connection, uninstall and reinstall the wireless adapter. To uninstall the wireless adapter, go to Device Manager and select Network Adapter, find the wireless adapter and right click on it, now choose uninstall and once completed restart the system. Reinstall the wireless drivers from the Dell’s support site. After the drivers are installed configure the wireless connection.
Hope this information is useful. Please reply with the findings.

Came across this thread when I was looking for a solution to the exact same problem. Command <ipconfig /all> returns "Media disconnected." for wireless network adapter "TrueMobile 1300". I can connect to the router using a cable, however, for the wireless adapter nothing seems to work.
I have tried:
So far, no change, I still cannot connect to the wireless network. Any additional suggestions you could come up with will be much appreciated.
