One thing I noticed that might help with your connection problem: Most modern WiFi gateways are dual band (2mhz and 5mhz I believe). The Samsung (and most other robotic vacuums) only work on the 2mhz band. I had some lost connection issues until I forced my smart phone or tablet to only operate on the 2 mhz band when I wanted to vacuum.

Well, I just received mine and had no problem setting it up and creating a floorplan. But due to the layout of my home, it put about 60% of my home into one room (I have a large greatroom that opens into the kitchen area and a hallway). Not getting much info from the manual, I called tech support and wasted about 30 minutes. I wanted to delete the created floorplan and find out how to subdivide my large area. They told me you cannot delete floorplans and you are at the mercy of the Vac to create floorplans. Here's what I did to resolve the creation of the floorplans I desired. I took some scrap lumber and created "barriers" in the large connecting rooms. After creating the first floorplan, I created a "path" with the lumber from the charging station to the next area to map. I did this for each floorplan I desired. Now I've got six good floorplans and two floorplans I'd like to delete (My wife is not very tech savy so simpler is better). Here's what I've found out so far about floorplans. I installed the Smart Home app on two tablets and a smart phone. Created floorplans from one device do show up on other devices. They must be stored in the vacuum. Samsung, if you're listening, please update the app to include a floorplan delete.
