Hi,

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?

In the BIOS, for the properties of the wireless NIC, power tab, uncheck the setting that allows the card to be turned off. In the Power Properties, Advanced Settings, set the Wireless NIC for Maximum Performance both Battery and AC.

Try that, as the default settings commonly cause wireless NIC to drop their connection.

My apologies - I meant Device Manager not BIOS. Sorry.

So then if you have done both of the above, it is entirely possible that the wireless card is not compatible with the D-Link Router.

You say it works fine with the NetGear access point. Try a couple of other routers (coffee shop, friend, work, etc.).

You may have to replace the D-Link with a better model (and I am speaking from experience).
