I recently moved my Acer Aspire desktop into a new case to fit my graphics card and power supply. Everything works fine but the internet and download speeds are extremely slow. I have integrated wireless on the desktop.

Manufacturer and Model of your wireless router?
Upon connecting hardwired, do you have a stable connection?
You may need to change the wireless channel to avoid any conflicts from other wireless connections within your area.
