Wifi performance crap after W10 upgrade

    Just upgraded this evening on my trusty Dell studio 1735 from Win 7. All good with exception of wifi which has literally taken a dive from what was approx 50-60mb download speed to approx 1.5 ! Ethernet runs at the full 240mb or thereabouts. Its a dell wireless 1510 WLAN card. Any suggestions from the clever folk here ?

    Ive a 5ghz and a 2.4ghz here. UPC Horizon. I'll roll back if I cannot get it resolved but plenty of time to fault find before I have to undo the upgrade. I'm sure its something simple such as a driver compatibility issue or the like but fecked if I can find the cause/fix.

    If it's one of the cards where Dell have compiled their own driver for it, the driver being shoddy is almost certainly the problem - I had a similar issue on my Dell tablet where the wifi & 3G is fine on Win 8 but gives crap performance and constant errors on Win10.

    To be honest, the easiest workaround might be spending a few euro on a USB wifi dongle - the alternative is either waiting for a new driver from dell or spending ages trying various driver releases for Windows 10, Windows 8.1 and Windows 7 to see if any of them give you better throughput.

    Cheers Fysh. I've ordered an Intel card that apparently works with W10. They've better supported than the Broadcom stuff anyway. I've rolled back for the moment but at least having installed it before the deadline, I can reinstall it now anytime in the future now I have the digital entitlement. Handy that!
