    Internet Connection Sharing and mobile hotspot. Windows 10 CU 1703


    Hi all,

    I have a problem with my network sharing.

    Let me explain first. The dorm I live in only has wifi. WPA2- Enterprise security. I am able to connect with this network with my laptop.

    Because I want to have multiple ethernet connections in my dorm ( For my ps3, smart tv, Blu-Ray player) I shared my wifi network and with an ethernet out port on my laptop I connected my laptop to a router. So the connection is ethernet port on laptop to Internet port on my router. From there I connected all my devices to the router.
    - This worked! Until now ..

    I was watching netflix on my smart tv. Laptop was on, the internet LED on my router was on, like it is normally. And suddenly my movie started buffering and netflix gave an error that it was disconnected from the internet. I restarted my laptop, router, tv, everything! And after about 30 minutes of figuring out what the problem was I noticed that when I share my network and have the build in windows hotspot disabled. The shared connection does not reach my router and my tv has no internet. Then I turned the hotspot on. No devices connected. And suddely my router got internet signal again.

    - Very strange. Now I cannot share my wifi network over laptop ethernet port to my router without having the build in windows hotspot turned on. This isnt that big of a problem. Except, The hotspot keeps turning itself off every 5 mins.

    And the weirdest thing is, I never had this problem before. I never even used the windows hotspot before.

    I tried reinstalling drivers, restarting router, Resetting router. There is no way I can undo this.

    Please help me. I think it is a bug in windows 10.

    Hi kevingriffioen.

    Have a look at your Windows update history. What was installed just before this happen? Have you tried rolling it, them, back?

    Here is what I think is happening. It is considered, at least in the Corporate world, a security risk to have a connection to a wireless network and a wired network at the same time. I think now you have the choice between wired and wireless. Windows sees the connection on the wired lan and shuts down the wireless connection. When you turn on the mobile hotspot that overrides the shutting off of wireless. Again I think.

    This article is Windows 7 but it gives you the concepts and for some screens the isn’t a lot of change in 10, at least not yet.

    Others may have a better explanation or fix. Please note exactly what you change so you can undo.

    Additionally, in light of a security hole recently discovered, they may have updated your router to patch it.

    Also, does the school throttle it down at a certain hour or when you use up your share of data? It is the end of the month.

    There was no update yesterday. The last update is from october 18th. And like I said, it worked perfectly until yesterday evening..

    I also tried changing the automatic metric. As shown in the post you linked. But that didnt help either.

    Well if no update and you think its a glitch then you could use the Network Reset built into windows 10. Although as pointed out maybe the Dorm's policies have changed.

    Start => Settings => Network & internet => scroll down right hand side => Network Reset

    You will "Forget" wireless passwords and may have to reset custom communication packages like VPN clienst.

    Additional if you have restore points enable you could restore to a time before the incident.

    Members use a tool like Macrium Reflect to Image their machines. Very handy to restore a machine to a working time. Please have a read.

    Excellent. When you say this work, was it the network reset. (or restore points) Glad the forum could help.
