Hi been awhile since I last posted. In the house we have a desktop and 2 laptops on the go in the house.The desktop is wired internet while the laptops are run on wifi.This worked fine until my isp UPC upgraded my internet speed from 50mb to 120mb.. The desktop and one of the laptops still works fine but the acus laptop has web access for between 20 mins to 45mins before the wifi drops off and becomes limited access. The wifi needs to be renabled to regain access to the wifi which lasts another small while until it gets limited access again. The laptop specs are: Acus K53e Windows 7 home premium 64bit intel Centrino N100 wifi adapter Ram 6gig At the moment its running for 30 mins then wifi cuts off for a few seconds before starting up again.
