Networking card question - which one to pick

[FunkyFeatures]

I have no clue which one to pick

Intel 7260 dual band ac wireless for m.2 in motherboard(It will fit in m.2 right?), or tp link tl wdn4800 for pci express.
http://www.edbpriser.dk/netkort/intel-dual-band-wireless-ac-7260-id-7361632.aspx - link to the intel one - i think it goes into m.2
Which one would be more reliabe? The router is in the living room, right up to a wall, the signal then has to go through two walls(in total a good 3-4m thick walls) and maybe 10m air.

My connection is 40down 10 up.

I have no real good way of wiring it up to a ethernet port. Also, suggest alternatives if you think something is better at the same price

the INtel one is more advances and has the 802.11ac protocol as well as all the older protocols.

I didnt think i mentioned it - but i only have N wireless network in my house, which is enough for what we use. Will it have inteference from a metal case?

 

[Karsten75]

All metal cases act as shields. Unless you have an external antenna connector it will affect it.

So a case like Enthoo luxe - not released yet, but i plan on getting it, would actually block the signal of the wireless card inside of the system? It will be mounted on the motherboard if anywhere

Not block necessarily, just weaken it.

Something like this externalize the antennas - not recommending this one, just took the first one I could find as an illustration.

Not recommending this one? It was my second choice.
WDN4800 or 7260ac, what would you recommend instead? I heard the wdn4800 should be pretty good - is it because of missing AC support?

 

[Karsten75]

I just took the link, didn't say it was good or bad. Sorry. It may well be good. I have no knowledge of it.

Ah, a misunderstanding. No problem. It was just that it is the most popular and recommended around.
