Windows 10: Internet Connection Sharing ICS is slow Windows 10

Hello,


I have a problem with slow internet using Internet Connection Sharing on Windows 10.


The scenario: PC A has no wifi antenna but needs internet. PC B has a wifi antenna and is connected to the internet via wifi. With an ethernet cable A is connected to B. B is using ICS to share its connection to A.

Both PCs are running Windows 10 Pro Version 1909 with latest software. The wifi and ethernet connections are marked as "Private Network".


As a result, I have internet on both PCs, but on A the download speed is way slower than on B.

Results on speedtest.net:

A - Ping 28, Down 3.31Mb/s, Up 2.19Mb/s;

B - Ping 23, Down 12.21Mb/s, Up 2.23Mb/s


Previously i had Ubuntu installed on B and using Ubuntus ICS feature it has a different name, A had a way faster internet connection about 99% of B's connection speed. Am I missing any settings?


Do you have any ideas? Thanks in advance!

:)

 

ICS (Internet connection sharing) dosent work in Windows 10 1607

For me, ICS recently broke on 1703 a while ago.

Down to «Error 1753: There are no more endpoints available from the endpoint mapper. ».

I've migrated to 1709 - and for a couple of days it worked normally. Now, it's broken again.

There's a chance that some common update package causes this on all versions. But I've not tried to find it yet.

Related feedback on feedback hub (for insiders):

• Internet Connection Sharing (ICS) stopped working automatically after Anniversary Update!
  
• https://aka.Internet Connection Sharing (ICS) hung up on "Starting..."
  - Fall Creators Update
• Internet Connection Sharing (ICS) freezes while starting

Non of them looks 100% perfect for me, so I've created one more:

• Internet Connection Sharing (ICS) stuck in "starting" state

Please consider upvoting, adding screenshot, your reproductions and etc if you want this fixed.

Personally, I was able to fix this by resetting firewall rules, as suggested in

Problems with Internet Connection Sharing after 2017-11 Windows 10 Update [Temporary fix found].

Simply do "Start -> type 'firewall' -> restore default policy" (consider creating a backup with "export Policy" before erasing it).

I'm not sure, maybe the issue would be back in a couple of days....

 

Internet Connection Sharing (ICS) not starting

I had the same issue.

Below is the solution which worked for me.

Internet Connection Sharing (ICS) never starts

After the most recent Feature Update (1709) it turned out that I can't use my Mobile Hotspot option anymore. After checking all possible options and searching for advises on the Internet for similar issues, I realized that in Services.msc, the status of Internet Connection Sharing (ICS) is frozen on Starting and it will never actually start.

I tried starting it with all 4 possible startup types, checked the status of the other services on which ICS depends (all of which seemed to have the desired default settings), run sfc /scannow, did a clean boot even with my third-party antivirus software uninstalled, even added a DWORD type registry key EnableRebootPersistConnection on HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\SharedAccess with value 1 as suggested on another forum. Unfortunately, none of that has helped me so far.
