    Hey guys

    So, as it may be apparent, I am currently using a DELL Lattitude E5420 which has an N 6205 Wifi card in it.
    Its not a bad Wifi card per say as it serves its purpose, but I have been experiencing issues with Wifi dropping out quite a lot (which could be due to Windows 10 and MS still not issuing that fix for my platform - they apparently released a fix, but as you know it takes time for the fix to reach certain OS-es).

    Its not a router issue as my mobile phone Wifi works fine when the laptop keeps disconnecting.

    Anyway, I was wondering which laptop wifi cards (of the more modern type) would work in this laptop as I was looking to potentially upgrade to a better wifi module.

    Try using this first:

    Intel 62xx and 72xx family of network cards always suffered from those problems, try using that utility/program first, because it fixed my unstable connections when I used those cards.

    If not, check if you have physical space and use an m.2 to PCIe half mini adapter and use the latest Intel AX200 card.

    I would steer clear of that. Engineering sample of dubious quality and origin. Also can't find it for sale in China, which is a major red-flag.

    M.2 to M-PCIE would better, but I've heard of some cases when it isn't working due to power demands.

    Quality control is certainly not factory level, but there's buyer protection against faulty cards. m.2 1216 cards soldered to adapter board have been around since Intel stopped producing mini pcie ones, starting with 8260.

    There is also ALFA AWPCIE-AX200 but it uses MHF4 antenna connectors and thus will require antenna adapters or antenna replacement. It is also both expensive and hard to buy.

    Then, there is 3x3 AW-CB160H, also with MHF4 antenna connectors. Needs 3x3 or 4x4 router otherwise it won't perform any better than 7260 802.11ac cards, and even then it is a far cry from AX200 while being more expensive.
