How to subnet a home network

[Shams Dimashki]

Hi Everyone

I have a project to share the internet across multiple flats.

I am planning to distribute multiple SOHO router for each flat to provide Wifi for the users

The problem is how can I do subnetting or use multiple VLAN for these flats (each network must be separate)

For the first step, I assigned static IP for each SOHO router (TP link MR3420) and stop the DHCP for each.

The ISP router doesn't have routing capabilities and I can't change it as well.

Can anybody tell me how I can do subnetting with a cheap and active solution ?

Is this real environment or Lab ?

If real environment, you need to invest on good AAA (like ISE to make it work)

since you looking to have one SSID for all Flats i guess 

you have not mentioned what WLC and AP you have - Do you have any cisco equipment here ? (if not then you are in wrong forum also post correct forum to get correct replies all time)

This required quite design consideration and lot of input required, better contact local cisco partner to help you.

Dear Balaji

Thanks for your comment

This is a only a lab but I am planning for a real project 

The SSID is unique for each flat so no need for WLC

for the authentication, I will use WPA2 personal included in each SOHO router 

All the mentioned AP can be any model as its purpose is to provide Wifi to the users

My problem is how can I make each flat isolated from others? 

Shall i add any other switch or layer 3 router to make it work? and which brand is suitable ?

As i mentioned this requires proper design and planning.

what SOHO Router ? This is cisco FORUM if this is not Cisco Router, then you need to post your query to Respected FORUM to address correctly.

If you installing each SOHO Router, then you need to Look Like DSL and DSLAM based to get an idea for you how you can distribute with central end HUB.

All the mentioned AP can be any model as its purpose is to provide Wifi to the users  - this was not clear to me is the SOHO router have AP built in ? or AP will be separated ?
