Max number of IP address a home router can distribute??

[legocitytruck]

I recently purchased a new wireless router for home use. The additional speed is nice but now different devices (sometime a computer, sometimes a printer) will display an error stating that it is sharing it's IP address with another device at the house. The device with this error message is unable to access the network or internet.

Is there a maximum number of IP addresses a home router can distribute between home devices? Is there anyway to increase this max number?

Each Router has a DHCP menu that let you set the Number of IPs.

I Life is so good that it usually let you set from 1 to over 100.

It is in the manual, or in the online support.

Where? Why? How ? - I do not know because you did not indicated which Router.

Thanks Jack, sorry for the omission.

The router is: Netgear N600 Dual Band Router WNDR3400

Duplicate IP issues is not you running out of IPs. Do you have a wireless card bridged to a network card someplace?

Assuming you only have one router acting as DHCP address server on your network, one or more of your computers/printers is probably misconfigured and using either a static IP in the same range, or pointing to a nonexistent router and using an old IP lease that conflicts with other devices on your network...

Isn't the answer 253 for most home routers with a DHCP server? Every Linksys/DLink/Netgear router that I've worked on lets you assign x.x.x.2 to x.x.x.254 via DHCP.

Like imagoon said, you probably have some fixed IP addresses or "stale" DHCP assigned IP addresses if you're getting duplicate errors. Just set everything to DHCP and release/renew the addresses to fix it. If you can't change a fixed IP address to something else, just exclude that IP address from the DHCP range.

True, if configured as such as they are on a network with a /24 prefix, meaning there are 254 valid addresses, the router using 1 of them.

However most default DHCP setting usually have a 50 address pool. This could be changed of course, or static IP's assigned, but that does not mean the router will have the resources to allow all hosts to connect to the internet simultaneously. Each connection by a host on the inside to a host on the internet is stored in RAM in the router so it knows where to send the response and 'translates' the address to the internal host. The amount of RAM reserved for this can even be configured with third parts firmware such as DD-WRT.

I checked the settings and the router has 253 available addresses.

I recently hooked a TRENDnet 300 Mbps Wireless N 4-Port Media Bridge Up to the reciever in the basement to allow control via cell phone from various rooms. It sounds like this device is causing the router to send the same IP address to different devices.

Aye the short answer is "1 c block" or /24 is typically what a router you buy for your house will hand out. As for the protocol - Any number. We have a DHCP server in use that has over 120,000 entries over thousands of blocks.

Make sure that the Trendnet DHCP is Off.

Its core IP is the same subnet as the Source and its specify core IP is Not used by any thing else on the Network.
