Problems with AC7260 wireless adapter on Latitude E5440 w7

Hi to all

I am new on this community, however I tryed to find an answer about my wireless adapter.

Problems with AC7260 wireless adapter on Latitude E5440 w7, I see my wireless router, I knew the password, SSID, but I cannot connect to this one. This is the second router with the same connection problem. I cannot change the router settings because is the workplace.

I tryed to update the driver (latest v17), changing adapter settings with different protocols, no success.

My collegues has the same laptops, they don't have any issues to connect to the same router. Is there some solution to find out why I cannot connect?

I tryed to make my phone as hotspot for wifi access, this was OK. Connection succeded.

Please give some advice because I am stucked.

Thank you

Peter Veres

Hello petike779,

Is this wireless card the original one that came installed in the computer when you bought it, or was it installed later?

If it already came installed, we recommend that you contact Dell first to see if they have any updates that might resolve this issue. Here is a link to Dell* Support Page that might help you as well: http://www.dell.com/support/article/us/en/19/SLN285330/EN Latitude E5540 and E5440 Windows 7 driver install order | Dell US

Thank you for the answer.

Yes, it was bought with the card installed already. It is a genuine w7 and all software's also (corporate pc with administrative rights for me).

Unfortunatelly I already tryed what you suggested. No success...

Some other ideea?

In this moment I use an USB wifi adapter to this purpose...

Cheers

Hello Petike779,

have you tried to connect to any other network other than these two and see if the same thing happens? You may also try to connect to a public network and see if the same thing happens.

To check with your computer manufacturer would be the best option since the wireless card came already installed and this fits the characteristics of an OEM's (Original Equipment Manufacturer).

The reason we are suggesting this is that being an OEM card, the manufacturer has adapted the card to be compatible with their system and in this particular case, only them are entitled to provide you the correct drivers that might resolve the issue. Please check with them and let us know as you since it connects when you use your phone as an AP.
