Hi friends,

I am using Comway broadband connection at my PG. I have 4 floors and currently the BB is installed on the 3rd floor. I have to give wifi to all the other floors through that connection only. Please suggest me best method to do it.

Currently I have Comway modem with 2 lan ports, two pieces of Deco M4 and one Tenda N301 modem. I also have one airtel modem which I hav'nt used since last 3 months and currently its wifi has been paused as I am using comway wifi.

With regards
Rohit

The 2 Deco M4 units should be able to create a mesh network but it might not be enough to cover the entire area.

Need to create a MESH setup. Deco M4 should work, but may need one for each floor. First check if Wifi signal reaches either 4th floor or 2nd floor. Place the second M4 in either floors and verify.

If this is successful, you may buy 2 other Deco M4 for this.
Don't use Network extender (would face duplicate SSID issue frequently).

I tried creating mesh network but it was not able to give food coverage to all parts of those floors.

Hence I HV put cat6 wire on all floors for connecting the m4 and the n301 router with the router provided by comway.

But now I found that comway router has only 2 lan ports, from one of that port I send one wire to 4th floor and from another port I send one wire to 2nd floor. From 2nd floor i connected one mesh and from that mesh i attached another wire which went till 1st floor. These settings were done by a network engineer.

1. Now the network is good on all floors except @st floor where I have used n301 router as it's speed is limited to 100mbps

2. As the main router has only two ports, i am unable to connect my cctv internet port to it.

Pls tell what to do for (1) increasing the speed and (2) connecting cctv port as I bought one splitter too but it didn't helped.

You've done so many things, why stuck with Comway router then, invest in a good router with more ports?

I know but their router is good and I don't want to invest much hence was thinking to buy either POE switch or network switch, whichever is better.

Pls also tell what is PoE injector ?

Switches are the best to convert 1 LAN port to more.
Just don't make the mistake of buying a non gigabit switch like I did (as mentioned in this thread: *geek.digit.in/community/threads/suggestion-on-a-switch-for-home-networking.212632/)
Also you might save a lot of money, if you don't need a PoE. Just get a gigabit switch.
