Acer Aspire ES1-533 connectivity issues.. help!

[rubytuesday.h]

I've had my Acer Aspire for about a year and half, all been going fine until I mucked around with it and disconnected a ribbon connector on the inside of the laptop (not sure if keyboard/touchpad or motherboard), no lights would turn on, no screen etc, nothing. Anyway, all fixed now, had a guy come out and reconnect it no problem, works again like normal except for the wifi??? I've never had an issue connecting to my home wifi before, but since it's been fixed, I can only connect to my wifi sitting right next to the modem (only 1-2 bars signal) and no bars anywhere else. I know it's not the wifi itself as otjher family memebers laptops work fine on it and no issues. Purchased a wifi adapter hoping that would help & the network won't even be found on that adapter.
I'm stumped. I've checked the software and doesn't seem to be anything out of the ordinary there.
Any suggestions???

The answer might be in the Properties of the device in Control Panel>Device Manager, given that your device is off the suspects list having been joined in there by the new adapter..

For example, check under Power Management to see if it can automatically be turned off to save power and change that.

Next, under the Advanced tab, check 802D and 802.11 to see if either disabled and reverse that setting.

Rack the Roaming aggressiveness to Medium (4) and finally, check the Wireless Mode.
