So I got a new computer recently and have installed a tl-wdn4800 as the network card. However, the download speed is so terribly slow (25kb/s) that it took about 15mins to download a 29mb file. I have installed the drivers, uninstalled and reinstalled again too many times. It is not the router, my other computer downloads at 1.9-2.4mb/s using the same wireless network. Any help would be appreciated.
