Windows 7: PC not automatically connecting to wireless network

We recently moved to a new internet provider and a new infrastructure company.

We got a "Hotbox" as it's called, wireless router + modem + phone hub or whatever.



When i connect to it from pc, i check "connect automatically" like i did with former network. Every time I turn the pc on, however, it doesnt connect. Like it forgot i asked it to.
It should be mentioned: when i restart the computer, in seems to auto connect to network. When i turn off, and then after some time back on, it doesnt connect.

Any help is appreciated.
I live in israel, and the infrastructure company is HOT, supplier is Netvision.

anyone?
Important: it seems this problem occurs only on my PC. the netbook we have , Windows 7 Basic , 32bit i think, doesnt have this issue. Nor do smartphones.

Hello Inuyasha,

Updating your Wi-Fi adapter to the latest might help. Also, disable the Power Management Mode of your Wi-Fi adapter frm Device Manager, see attached image.

An update will be nice.
