Hi all, I have an older dell laptop, a latitude D531. It has been upgraded with 4GB of ram, a SSD and Windows 10 Pro 2004. It runs pretty well, and almost all drivers installed perfectly, the only driver i had to install was the graphics to get the full 1440 X 900.
But i am having a problem with the wireless download speed. The laptop had the dell wireless 1390 G only card. I was getting 1.4Mbps download, so i thought by upgrading it to a 1505 wireless N card i would see some improvement in download speed. That did not work out that way. Even with the new wireless 1505 card, im still seeing only 1.4Mpbs download with normal 13.5 upload.
I did search and try a couple different settings in router and on laptop, but nothing is working... The Alienware on the same network, just feet away from the D531 will get over 100Mpbs download.
Any Suggestions? Thanks!

UPDATE:
As a last ditch effort i downloaded the "official" wireless driver from the dell website, and my download speed jumped to 68Mbps!!
