BleepingComputer.com: Help with Wireless Connection Instablilty

Hi there, I'll try to be as detailed as needed,

After my previous wireless modem was spoilt, I got myself a new wireless modem --
Previous Modem: Linksys Wireless-G WAG200G
New Modem: Linksys Wireless-N WAG120N

After installing the new modem, my laptop can connect to the wireless network just fine, but my desktop (having the [TP-LINK TL WN-727N] USB dongle) couldn't connect at all; not till I go to the Wireless Network Properties and checked [Connect even when the network is not broadcasting its name (SSID)] in the [Connection] tab, and even then the connection is unstable, it changes from



to



and back constantly and shows at the taskbar.


How do I go about fixing that?

Nevermind, issue solved.

Thanks anyway =)

How did you solve the issue?
