Surface Pro 3 Slow WiFi - 72Mbps Max (driver)

Anonymous

I have an Apple Airport Extreme 802.11ac wireless router at home and am only connecting at a max of speed of 72Mbps (usually closer to 11Mbps if I'm more than 20 feet away from the WAP). I have two other 802.11ac laptops at home (Samsung AB9+ and rMBP) and my two other computers are connecting up at 800Mbps+ and pulling down the same on Internet speed tests; yes, I have real GigE connectivity. Is anyone else having these problems?

    Actually, that is not a bug.  That is designed deliberately.  When you go high speed with the WiFi adapter on battery power, your battery will last about 30 minutes with a heavy data transfer load.

    Laptops have done that for years and nobody ever noticed it.

    It is not a defect; it is supposed to do that.

    Been fighting my SP3 I5 since I got it Sunday as well. Overall it's a nice little setup. The 802.11ac works but dog slow... almost better if I stay with N instead of ac. Pen connects about 1/2 the time. Getting tired of it. Should have waited for the I7 version I preordered. Maybe they'd have had more time and hopefully gotten this straightened out. Thought that by SP3 they would have it down pat....

    Will try deleting the driver to see how that goes. If not it's rebuild and back to Bestbuy.

    You want the driver dated 4/24 an with .67 on the end.

    I finally got the work around mentioned in this, and other threads, working.  Here are the steps I took:

    1 - Disable auto updates

    2 - uninstall battery driver

    3 - uninstall ac adapter driver

    4 - uninstall wireless driver - The difference I did this time was to uninstall the software associated with it. You'll get a dialog box with a checkbox.

    5 - reboot. Give the device a moment to reinstall the drivers and then reconnect to the network.

    Go into your updates and you'll see the 6/19 update that you DON'T want to install.

    WiFi is faster than before, but I'm still only around 54-72mb.

    Am a few feet from the router now and getting a solid 400 meg so I'm a happy camper.... just hope that it stays this way.

    Thanks again!

    For me it worked only for the first hour or so and then eventually it got very slow once again.  I found that if I ran speed test the next day it would be very very slow again.

    Good deal!!!!

    Went to Device Mgr and deleted just the Network Adapter and clicked on delete driver. Rebooted and now I'm @ 162 meg on ac!!! Am a good 40ft and a couple walls from the router. Checked Oklaa and am getting 65 meg down and 12 meg up which is max for my connection.

    Thanks guy!
