Wi-Fi wont connect a lot of the time

I am using Windows 7 32-bit SP1 with a Belkin 54G USB Adapter, sometimes when I boot it does not connect..but rare,

but ALL the time if the computer puts itself too sleep the wifi will not connect when I come out of sleep, sometimes a troubleshoot & repair will sort it, sometimes it wont and say its access point - but if I put the comp too sleep then wake it shortly after the wi-fi is working? seems to be when the computer sleeps it

things I've tried:

1. I have changed the WI-FI adapter settings so windows can not turn it off too save power.
2. I done the same in the power settings within windows "Maximum Performance"
3. the WLAN service is set to Automatic

now I had been playing with Windows 7 Manager program and it somehow (wasnt my choice) removed the wi-fi icon from my tray, sometimes when I boot its there, sometimes it isn't, I used a reg fix to restore the icon - its been since all this I have noticed it the wifi issue, but also I have stopped a lot of services running at boot and Iam wondering if thats why? however I would have thought it would not work at all if that were the case.

can anyone help with this?

I can not use standby or hibernate

I dont have a restore point either cos I have had a freeze and had to force a shutdown and lost all restore points (this is common in windows)

just to recap: its not just sleep, sometimes booting up as normal and wi-fi wont connect

thanks

Have you re-installing your Wi-fi card's drivers?

its not the channel, ive tried that

I havent tried re-installing them no... good idea, ive had 1 or 2 crashes recently they could be corrupt (slaps myself for not thinking of that myself)

I will do and see how it goes...
