I have dell vostro 5470 with n7260 network card and its wifi reception is very week relative to pretty much any other laptop or even smartphone.
I just tried replacing the network card from another laptop, that has no problems with wifi and woula! - it installed the drivers and worked, I had stronger signal and could see and connect to signals I couldnt even see at all before.... for about a minute or so, then all the signals disappeared and im back to bad signal.
While at it, I put my original n7260 in that other laptop and it worked fine, with strong signal.
First I thouht that its something to do with my laptop casing itself, but after this switch, when it worked.. but for a little while - it must be something in the software, doesnt it? But what? Something changed in the registry for some reason? Some power levels decreased?
I am running Windows 10. (and, actually, it was the same with win 8 and 8.1)
* when I replaced my HDD and installed a fresh OS, it too worked fine.. for about a minute or so after boot up.
* and it doesnt matter what driver I install or completely uninstall the driver (including driver software check box)
Of course, I tried googling, but I mostly get "8 ways to make your internet faster" or something like that, which is not for me - the signal itself is week and I cant even see many connections that other devices can see, unless I go very close to them.
