    Windows 8.1 Tablet Reverse Tethering?


    Okay, so I acquired a Windows 8.1 Tablet (Surface Pro 2) recently and my wifi router just went dead yesterday so I had to directly plug in my modem to my desktop PC. One of my friends who has an android tablet told me he could "reverse tether" his tablet using his Windows PC's connection via USB.

    I was wondering if this was possible with Windows 8.1 tablets? Can you connect to a PC running windows 7/8 that has internet via USB and share the internet connection that way?

    I won't be able to buy a new wifi router until next week so I was just wondering if there was another way to connect via cables. Thanks for the replies in advance.

    if your desktop is connected via a cable to your modem and you have a wireless adapter on that desktop too, you may be able share the network with an Ad Hoc setup.

    open network and sharing center from control panel(in windows 8.1 or just by clicking the icon in the tray in win7)
    click "local area connection" in the Internet Connections area
    Choose Properties
    Sharing
    Share connection

    I think you can connect to it after that with your surface, but it's been a while since I used this method. Certain firewalls may block it or get in the way, I only recall Zone Alert firewall doing that, though.

    In addition to tannim's post, you must enable and create hosted networks to that Marvell WiFi adapter on the Surface 2 Pro to create a portable hotspot. Now all of the devices that connects to the Surface Pro 2's hotspot will get internet connection per tannim's post.

    Ah thanks for the reply. I'll try Tanim's suggestion since I do have an extra wifi usb adapter lying around. I'll try that once I get home. I have Norton 360 on my desktop so I'll make sure to add a rule or exception on the firewall.

    Please bookmark this guide (link: About the Wireless Hosted Network (Windows)) since it explains how to create a portable hotspot with your WiFi using command prompt. If the hosted network is disabled, you enable it first then set your Ssid then password. Finally start the hosted network to create the hotspot. Make sure to share the internet in the "virtual miniport adapter" (that's the portable hotspot you created.) from tannim's post.

    In case you need a picture tutorial for it, just see my post here: cannot share internet (wired) from laptop with mobile devices - Windows 7 Help Forums

    Okay, I was able to setup an adhoc network on my Windows 7 desktop. I've got an old Netgear WG111v3 usb wifi adapter that supports adhoc networks. I did find that guide that theveterans linked and was able to use it. However from time to time I get kicked out of the wifi network from my tablet and when I try to reconnect it says its unable to. Even tried connecting with my android phone just to check and the same thing happens.

    I noticed that for about 8-10 minutes it works fine then it suddenly drops everything. I have to delete the adhoc network and re-create it again for it to work. Then it eventually drops everything again. I tried disabling the sleep mode and power saving modes of the wifi usb adapter thinking it was the reason but the same thing happened.

    Any suggestions on this? I'm a bit stumped.

    I haven't used that feature for extended time but to me it seems like the netgear usb can't handle too much network traffic.

    You can try doing multiple streaming with the adhoc network and see if you can reproduce the drops with just heavy networking. You can also try another adapter and see if it fixes the issue.

    Well the windows tablet is the only one connected to the adhoc network and all I'm doing is facebook and a few tablet games that require an internet connection.

    I guess I'm out of luck I suppose since the netgear is the only adapter I have. Ill just have to wait till payday until I can get a new wifi router.

    Thanks for all the help!

    well I'm happy that at least you have a temporary solution (albeit unreliable) until you get a new router

    A little internet is better than none at least : )

    Make sure you have the newest driver for your wireless device on the desktop.
