Hmm. It should be 1.2. Perhaps my link was wrong. See https://garage.maemo.org/projects/wizard-mounter/.
Please uninstall 1.1 and download latest version - 1.2.

I assume both your laptop and n810 can connect to the Internet.
Your routers SSID does not apply here. It's only necessary to connect your computers to your router. Thereafter, your computers connect to each other via the router. ie. ignore the router from here on out.
First, ensure that you have enabled "File and Print Sharing" on your laptop.
In Explorer, right-click on a folder you want to share. Click on Sharing and Security...
Under Sharing tab, click Share this folder. Give it a Share name, preferably one with no spaces. Click on Permissions and ensure Everyone has access.

On your n810, start Wizard Mounter.
Click Add
Profile Name? LaptopShare
Server Address? IP Address of laptop
Remote Directory? Share name above
Username? blank
Password? blank
Click NFS or Samba? Samba (NFS is for Linux servers)
Click Save

You should see something like this screenshot.
Click on LaptopShare then Quick Mount.
In File Manager, look at internal disk in directory Remote.
Success!
