HP 2540p + Intel 7260HMW AC

[Paul_Tikkanen]

You're very welcome.

Sorry that you weren't able to easily do something to get the card to work in the 2540p.

Dell doesn't have BIOS whitelists on many of their old PC's

I installed a dual band Broadcom wireless N card with Bluetooth in an old Dell Latitude e4200 and it worked just fine.

I had an Intel 7260N card too but it has exactly the same specs as the Broadcom card and I had two Broadcom spares lying around.

The notebook ran fine on W7, so I upgraded it to W10 (when you could still get the free upgrade through last September) and gave it to one of my son's friends who has a young daughter that he said would make a good 1st laptop to use.

So, finally last step...

Because we can't modify whitelist, we can to use external modules.
For reasons of compatibility with Win7 and reasonable dimensions, TP-Link T3U Nano was chosed.

Brief comparison between native (Intel 6200AGN) and this solution when connecting to a WiFi6 router on 500 Mbps WAN channel :

Win7

Native:
2,4 Ghz https://www.speedtest.net/result/15950367817

5 Ghz https://www.speedtest.net/result/15950374045

TP-Link:
2.4 Ghz https://www.speedtest.net/result/15950417894

5 Ghz https://www.speedtest.net/result/15950403680

Win10
Native:
2.4 Ghz https://www.speedtest.net/result/15950503988

5 Ghz https://www.speedtest.net/result/15950516050

TP-Link:
2.4 Ghz https://www.speedtest.net/result/15950549499

5 Ghz https://www.speedtest.net/result/15950557272

The result, of course, is far from ideal, but...

Yes, that is one way to improve the wireless throughput when there is a whitelist.
