I made an account just to ask this. I'm trying to run this on my laptop and I've got an Ethernet plugged in and I've got a wireless open. I've done everything right in the tutorial but I keep getting this error when I press "Start Hotspot."
"An operation is blocked waiting for an oplock. (Exception from HRESULT: 0x800702FD)"
I've not a clue how to fix it.
Does your laptop have a spare wifi adaptor?
I found a way to fix these issues was to
A. Open the command prompt (type cmd into the start menus search bar)
B. Type: netsh wlan set hostednetwork mode=allow. then press enter.
C. Type in NCPA.CPL into the command prompt.
D. Right click on your Spare adaptor (the one not connected to anything.)
E. Click properties, then click the sharing tab.
F. Check the box that says "allow other users to connect to this network"
G. Where it says "select a private network." Set that to Local area connection (aka your ethernet cable) Make sure you confirm this choice with the Ok button before trying the next steps, otherwise it wont have updated.
H. Open instacheck and set the shared connection to Local Area connection. Name the hotspot and set the password then click start hotspot.
I. If you check the NPCA.CPL window again, it should say that your hotspot is connected to the wifi adaptor also.
After this you need to head to connection settings on the DS. Make sure the hotspot is connection 1 otherwise your DS will try to connect to the home network and it will not work. Keep in mind should the DS disconnect from the hotspot for any reason (The ds itself not pokemon) You will need to completely stop and restart the hotspot. If you're still having troubles after trying this Pm me here and I can try set it up for you with team viewer.
