Trouble connecting to AdHoc network

Question

I have a Dell Latitude 10 tablet running Windows 8.1 that cannot connect to an AdHoc network.   The computer initiating the AdHoc network is running Windows 7.  The host computer seems to think that the tablet is actually connected but the
tablet just spins and then finally returns a timeout error.  I have been working with a Dell technician who had me try the following commands to no avail:
netsh wlan set hostednetwork mode=allow
netsh wlan start hostednetwork
Any insight would be much appreciated.

Answer 1

Thank you for your response.  The AdHoc network was OK and could be accessed by Windows 7 and other Windows 8.1 devices.  Since Windows 8 and 8.1 do not show adhoc networks in the available wireless connections list, we used the following
commands and got it to work on a Windows 8.1 laptop but not on the tablet:
SETUP:  
This must be done once per network.
go to "Network      and Sharing Center"
click "Set      up a new connection or network"
double      click "Manually connect to a wireless network"
enter the      SSID of the ad-hoc network (as shown by "netsh wlan show      networks") into the "Network
name" field
configure      security settings accordingly
uncheck "Start      this connection automatically" (important)
click "Next",      then "Close"
Run this command (important):
> netsh wlan set profileparameter <ssid> connectiontype=ibss
CONNECT
After setting up, run this command whenever you want to connect:
> netsh wlan connect <ssid>
Replace <ssid> with the SSID of your network.
RESOLUTION TO THE PROBLEM:  This made us think it was some kind of a hardware issue with the tablet so I purchased a USB wireless adapter and was able to connect to the Adhoc
network using the commands above.  It then showed up in the Network and Sharing Center as an Unidentified Public Network.  Apparently connecting to an Adhoc network will not work on the Latitude 10 tablet with the current wireless NIC drivers
from Dell.
