I have 12+ users in a small company & we are having one Belkin modem+router normal one...Now whenever we having any guest or some vendors in our company. our current router is not supporting all or two users will not have as a option i have connected one netgear wifi router to the main Belkin router via lan cable & everything is working fine..but some users on Netgear (secondary) is having printer issue, they are not able to print & we are using lan messenger, that is also not working, i understand coz of different ips its not working, but there should be some workaround...

Pls help.

When you say "Now whenever we having any guest or some vendors in our company. our current router is not supporting all connections", how do you know this? Are they connecting via WiFi and it won't allow them to connect or is everyone cabled in and you are out of ports?

You shouldn't be using two routers in this setup.

You should be using the one router you have (or perhaps buying a better one if this isn't up to the task) and connecting a switch and/or access points to it.

You should be able to buy a 24 port gigabit unmanaged switch for a pretty good price and that should suit your requirements fairly well.

If it's just that the connection is too slow (i.e web pages are loading but taking forever) then you'll want to talk to your ISP about upgrading your plan.

I also agree with what davidgo said about your DHCP pool may be too small, pretty unlikely on a home router since they normally use /24 masks but you could try looking in your config and reporting to us what your subnet mask is.

You want something like the following diagram:

Thank you Mokilok for answer. Your suggestion is pretty Hub will manage the IPs. I know this solution but as we are in temp. office am not interested in any investment. regarding "our router is not supporting" means system is not getting connect to the router., its showing error not able to connect (all wifi) I have one small 54mbps wifi router. i want to connect that to have the more users connected to net., but by that printer in not accessible by users connected to sub-router (netgear) & lan messenger also not connected. – Yogi Mar 4 '14 at 8:30
The two users that can't connect, are they using older network technology? Sometimes modern routers won't allow older wifi technology to connect. It sounds like you have your two that can't connect normally connecting two your second router but now because they are on an different network they are unable to print? You have plenty of IP address space in your subnet, you should disable DHCP on your second router and made it act like a switch/access point. It should still broadcast wifi so your two users should still be able to connect but it won't treat those users as if they were on a 2nd LAN. – Mokilok Mar 5 '14 at 1:25
But if i am disabling DHCP on secondary then my problem remains same... – Yogi Mar 5 '14 at 2:50
Disabling the second DHCP server shouldn't disable the second SSID. They should still see it and be able to connect to it. – Mokilok Mar 6 '14 at 2:55
But primary router is not assigning IPs if systems qty is more than 13~15.16th system will get error cannot connect to "ABC" (SSID) router. that's why i put secondary router.Now printer setting I managed, only remaining thing is Lan messenger. – Yogi Mar 6 '14 at 3:06

If you have 12+ users in your small company you should be able to afford to get a networking specialist to have a look at the problem - and that is what you should do.

There are many ways of solving this problem - however you shouldn't need more Internet connections to do it (unless speed is an issue). Indeed, adding more connections just makes the networking more complex.

While I can only speculate based on what you have advised, I suspect the problem is that you are using DHCP to assign each PC an IP address, but have not set aside a large enough range of IP's, so IP's are being reused causing problems for some users. The easiest way to solve this is to simply up the number of IP's.

A secondary problem you may be having - when you try and rejig your network - is that some devices may be behind "double nat", which could cause reachability between devices on your network and is not ideal. (Assuming you do actually need this complex structure - which is unlikely) - a network specialist would be able to come in and renumber and rework the routers such that the devices can all talk to each other without NAT between them (by breaking up your internal network into multiple subnets and ensuring routing between the subnets).

If you do need 2 connections, you probably need special hardware to drive/maintain this, as it means load balancing the connections in some way, and also ensuring that there are no collissions between the IP addresses handed out (one problem might be you have 2 DHCP servers running because you have 2 routers).

Thank you davidgo for your the IT guy here...actually we are in temp. office coz our actual office is in construction stage. We'll move there by end of this for time being we have to manage with limited sources. Now you have talked about ip range in DHCP...the set range is from 2~253. I guess that is the maximum range one router can offer. The double nat is not at all applicable here..coz our networking is not complicated. – Yogi Mar 4 '14 at 6:29
