I just bought a brand new dell pr m6800 with a dell wireless 1550 802.11ac wireless card.
I can connect fine to a Net Gear Access Point at my work, but it drops the signal when connected to a DLINK DIR 825 Access Point (both APs WPA2-psk). I have replaced the dell wireless card (dell tech support sent me a replacement) , but it still doesnt work. All other devices seem to connect fine to these Aps. Any suggestions?
