It looks like a particular issue with such connection because it works with your home connection. At this time it is difficult to know the reason why it does not work there but it may help to contact the network administrator.
Intel® My WiFi Technology has been replaced by Intel® My WiFi Dashboard and the best advice to get it working is to completely uninstall previous versions of Intel® Proset from Programs and Features and the wireless driver from device manager before installing the new version.
When installing the new version of Intel® Proset we suggest selecting custom install, just to verify IMWT component is marked for installation; then you may install Intel® My WiFi Dashboard. System restarts are recommended after every change. Please bear in mind that only the wireless connection will be shared.
I have installed Intel My WiFi Dashboard and the relative version of Intel Proset successfully, it seems to be the full version of Intel My WiFi Dashboard and all the features are available but there is still a problem. Actually when I wanted to share my laptop internet with my phone through Hotspot, at first the phone connected to the WiFi Hotspot well but after couple of seconds the connection dropped off and my phone got disconnected, I repeated this process several times but the same thing happened and every time the connection dropped off after a few seconds, so I could not be able connect my phone through Hotspot. I could not understand what is wrong with Intel My WiFi Dashboard that makes this happen!!
Thanks in advance for helping.
P.S. I have Intel(R) Centrino(R) Wireless-N 1030, and I used to share internet with my phone by Intel My WiFi Technology before.
