Unfortunately, those cards will not work in the D630. You may want to look online for a USB WIreless card.
Dell has only tested the below cards in this computer. Also, the computer does have any PCI-express slots. So, it cannot handle the card you mentioned. The compuer shipped in 2007 with Windows xp and vista. There is not support for larger newer cards.
Dell Wireless 1390 WLAN MiniCard, Wireless 1490 Dual-Band WLAN MiniCard, Wireless 1505 Draft 802.11n WLAN Mini-Card, Wireless 1395 WLAN MiniCard, Dell Wireless 13xx, 14xx, 1505 MiniCard, v.126.96.36.199, A31-1
Intel Intel(R) PRO/Wireless 3945ABG Network Connection, (R) Wireless WiFi Link 4965AGN,
Although most likely not tested by Dell, nevertheless the Intel 7260AC WIFI part works very well with the D630.
** What works:
- the WLAN adapter up to 866MB/s
I use Ubuntu 16.04 amd64 and it worked out of the box and it is so much faster!
Despite reported elsewhere, the card doesn't have issues with standby or be put or taken from the docking station. Actually, it works much better than the stock WM3945ABG card with which I had regular issues after standby.
If you have issues with Windows, you can find users reporting that you should use older drivers.
** What does not work:
- the bluetooth 4.0 adapter. It is not recognized. Putting the WLAN card in another (newer) laptop, the bluetooth device on the adapter shows up. This post (superuser.com/.../getting-the-bluetooth-on-an-ac-7260-to-work) suggests that the bluetooth radio is accessible via USB or serial. It seems the pci-e slot of the Dell D630 does not have USB and/or serial functionality.
I ended up using the original 2.1 USB bluetooth radio.
Can you describe how you installed the 7260AC in your D630? It has a different form factor than the stock card.
