Hi @erickhdez1226
Have you checked the status of the Bluetooth adapter in Device Manager? It may just need the drivers updated
The laptop has separate BT and WLAN cards so if there is a BT card installed all you have to do is to upgrade the WLAN card to get both 2.4GHz and 5GHz capability.
Here is a list of the [https://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/latitude-e6410-e6510-specsheet.pdf|specifications] for the laptop.
Scroll down to ''Connectivity'' in the list to view all the WLAN card options that will work with the model. For example an [https://www.amazon.com/Intel-Advanced-n-Wimax-6250-622anxhmw/dp/B004M9NZIO|Intel Advanced-n+ Wimax 6250 622anxhmw Wifi] (supplier example only) has both 2.4GHz and 5GHz signalling capability.
If you want mobile service then try searching for a [https://www.newegg.com/p/0XM-005R-000M8|Dell Wireless™ 5620 Multi-mode HSPA-EVDO Mini Card (Gobi™2000) with A-GPS] (supplier example only).
Here's the [https://dl.dell.com/manuals/all-products/esuprt_laptop/esuprt_latitude_laptop/latitude-e6510_service%20manual_en-us.pdf|service manual] for the laptop.
Click on ''Removing and replacing parts'' and then select ''Bluetooth card¹'' (to check if there is one there if there isn't one listed in Device Manager), ''WLAN card'' and ''WWAN card'' to view the procedure to remove replace these cards.
¹ If there is no BT card installed search online for [https://www.parts-people.com/index.php?action=item&id=9889|Dell Wireless 375 Bluetooth module] (supplier example only) to find suppliers.
Here's a list of the [https://www.dell.com/support/home/en-au/product-support/product/latitude-e6510/drivers|drivers] for the laptop but there is only driver support up to Win7 so hopefully Win10 (if you have this installed) will have drivers for the cards.
