Switch with DHCP server

[rubantin]

I know I might be asking this wrong... But, I want a simple switch (8 port) for my home that will hand out it's own IP addresses.... What am I looking for in terminology?

All of my devices except for the wireless router, that I have in another building, seem to be affected by the choking of data.

I have a 4 port modem/wireless router that has become overloaded by the sheer number of personal devices attached to it as well as 2 unmanaged switches and a wireless access point. I would like a wired ?managed? (DHCP) router to handle some of the traffic...

How many devices are you handling?
What, specifically do you mean by "choking"?
What sort of bandwidth do you have serving this? Down/Up.

 

[rubantin]

10/1 bandwidth... 3 echos, 2 google home, 6 android phones, 2 roku, 9 wired PCs (7 are mining rigs) and an ooma. I want to run the mining rigs and PCs on a separate subnet....

BTW, I served in the AF from 82 - 86 main station was Bergstrom AFB... PMEL

That's only 23 devices. The DHCP in your current router should handle that easily.
With that incoming bandwidth and number of devices, I'd say that the 10/1 is the limiting factor.

But you can use any standard router for this second subnet. A managed switch serving its own DHCP would probably be much more expensive.

ok.. thank you... Unfortunately 10/1 is the best we can get out here in the boondox... but what is the appropriate term for the managed router serving it's own DHCP?

Any router will do this.
Connect it to the primary router on one of the LAN ports.
Tell to to obtain an IP address of 192.168.2.1. The xxx.xxx.2.x is the second subnet. Connect the desired devices to that.
It will serve up addresses in 192.168.2.xxx range.
For the number of devices you want on that, you'll also need a second regular unmanaged switch.

All of your other devices connect to the original, and get 192.168.1.xxx addresses.

Have a friend that said I could have an old Cisco 891W-AGN-AK-9 that was given to him... Said he doesn't know anything about it...lol... could I use this?

You are in for a massive learning curve to use that device. It is configured via line mode..no gui. The DHCP config is a confusing because it has a massive number of options. If you want to use WiFi that is even worse, you will need to closely follow the examples and it is a very strange method where you have to link the wifi radios to vlans.

I would say spend the $25 for a cheap consumer router if all you need is simple dhcp.

 

[rubantin]

can you suggest one that has a dhcp server in it? I just need 8-ports

 

[bill001g]

8 ports in a router is not common you will pay a lot more than necessary to get that. You are better off buying any router with 4 lan port and plug a 8 port switch to increase the number of lan ports.

You can get a 8 port switch for about $20. tl-sg108 is just a example and you can get it a bit cheaper if you buy a 10/100 rather than 10/100/100. A router that has 8 ports likely will be more the $100.

ok this is what I have right now..

DSL Modem/wireless router combo with 4 lan ports > 8-port unmanaged switch > wireless router

I have 5 android cell phones, 2 - Roku, 6 mining rigs, 3 amazon echos, 2 google homes, 3 PCs

They all worked fine at first. Now connections get flaky, both wired and wireless drop connections as well. I replaced the DSL Modem/wireless router combo with a new one (same exact) and after a couple of weeks the same problems came back... So, I thought if I could divide the network with another router and subnet it might solve the problem...

Hard to say it depends what is actually causing the problem. The devices should not be sending data between each other unless you are for example sharing files. So even if you had 2 pc transferring huge files between each other it will not have a impact on say another pc access the internet. You could have something like a duplicate ip address causing your problems. A second network might if you are lucky hide the problem but it is blindly trying stuff when you don't know the actual cause.

You should have no issues with capacity on a lan even with that number of devices.

If the problem is related to internet usage a second network will not help because all the traffic still must flow through the main router.
