Hi hoping someone can help.I have a Dell Inspiron 15 3000 laptop.The onboard wif adapter is only 2.4.I installed the Dlink AC 182 dongle installed the latest driver.My services is 50Mbps.When i do a speed test i get 2.5.Mbps I tried the Dlink on a lenovo laptop and get 51.When i do a speed test with on board wifi 2.4 adapter i get 25Mbps.Anyone have any idea why the Dlink speed is so slow on this Dell?Thanks
