    Fixing my daughter's Lenovo Y50-70. The one with the 15 inch 4k screen.

    New SSD and new install of windows but unfortunately I wasn't the first to try to fix it. Other guy left what I am hoping was only cosmetic damage.

    Anyway now that the dead HD is out and ready for its new demanding duty as a paperweight, it seems to work fine. Well fine except there are no bars on the internet access and it isn't spotting any others. The internet works, it just appears to be stretching.

    That's odd because my old dell does much better, and it has notoriously poor range on account of trying to get signals past a metal shell. To the point that I bought a different model (not with me here) for use where signals may not be so good. And that other laptop with its better range was...... a Y50-70. A 17 inch touch screen version.

    So anybody got a good guess what is going wrong? My thought is that the aerial wire is loose, but I ain't opening the thing up again till I have had a good long think.

    Sure sounds like loose antenna connectors.

    I always double check that and put a piece of tape on top to make sure they wont pop out.

    Hmm. Always worth getting a second opinion. Located the wifi module in the manual.
    Could open it up again n just give the connection a quick fiddle. If nothing obvious I am just going to put it back together and maybe consider a professional repair. Maybe an external usb wifi and be done with it, but that would be a shame.

    Or, you could just spend 5 minutes to pop a $20 Intel AC8260 or even an AC9260 in there and see what happens. ;)

    Wish I knew what those thing were..... Ok checked. looks much like mini modem board already in laptop. But is it plausible that one inside is functional but working poorly?

    Hmm £13 from Ebay, local free delivery:

    Intel WiFi Card Wireless-AC 9260 NGFF NGW Dual Band 802.11ac

    Would that do?

    Edit: have to say cables look connected & Not convinced both are broken. What would the result be of just one functional? Right now what should be a decent connection keeps dropping out.

    Anything is possible. For ~$20, you can't really go wrong (return if not needed/didn't help, of course).

    What is inside already? Check the Windows Task Manager for details.

    Just make sure you do not buy an Intel AC9560 card. That needs additional chips on the M/B to work properly, which your notebook probably doesn't have. ;)

    Ebay's deal is cheaper & local. Newegg is £20

    Not opening the laptop up again tonight but from "view your network properties it is a:

    qualcomm atheros ar956x. Status is operational. link speed 144/72 Mbps

    Updating drivers was first act. Never fiddle with hardware till you are sure it ain't software.

    Ang on.........I think I have found the problem.

    Checked out my internet box. It runs at 2.4Ghz or 5ghz. Whichever it recons is better.

    The ar956x only works with 2.4Ghz which can get congested. I live in a tower block so kinda likely that.

    That £13 Intel AC 9260 board is dual 2.4Ghz and 5Ghz.

    So the last question....am I likely to have driver problems if I upgrade to it?

    No more likely than what you're facing now.
