Dd-wrt as access point

Dd-wrt wireless access point using a linksys router

I want to set up a home VPN, and I was planning on doing so with DD-WRT. The issue is that DD-WRT does not help our new router. DD-WRT is supported by our previous router, and I have already installed the firmware on it. The issue is that we need to use a router that does not support DD-WRT as our primary router for a variety of reasons. I’m curious if it’s possible to use a DD-WRT router as an access point on an established network that isn’t operated by a DD-WRT router while still using that router to set up a home VPN.

Setup virtual access point (vap) better known as gust wi-fi

Simply hard reset the router and set the router’s IP to, for example, 192.168.5.1 on the standard setup page if you want a secondary router to be on a different subnet than the main. Then, on the Wireless tab, set protection and SSID, click Save then Apply, and finally, link the LAN cable from your primary router to the WAN of the second router.
Allow Web GUI management in the Remote Access section of the Administration/Management page if you want to be able to access your secondary router from devices on your primary LAN. By typing in the secondary router’s WAN IP, you should be able to connect to it. Setting up a static lease for the WAN interface of the second router in Services on the first router would enable you to always know where the second router is so you can access it. This is the standard router/gateway mode, which is NOT the Wiki’s main target.
Side note: If you want to fully separate clients on one router from those on the main router, you’ll need to use IP table laws. This can be accomplished by following the above “Separate Subnet” instructions.

If you have a wide network for which DD-WRT is not a suitable core router, you would almost certainly want wireless clients to be a part of it. Clients would get DHCP setup from another DHCP server in this scenario, and other clients on the network could access it.
Some colleges, for example, that still enable students to have their own wireless access points (WAPs), require that the WAPs do not assign private IP addresses (as many routers with DHCP/NAT do by default), since this makes it difficult to determine which client is causing problems (eg. virus infections, worms, etc.)
Since routers are typically used by home users and WAPs are more common for businesses, vendors such as Linksys charge more for devices that act as standalone WAPs. With DD-WRT, you can buy a router and transform it into a wireless access point.
When you plug your router into the network (after configuration), if you didn’t switch off DHCP, your WAP can provide IP addresses to clients on the wired network, which may be inappropriate. It can be time-consuming and difficult to track down problems caused by multiple DHCP servers.

Dd-wrt how to set-up an access point (ap)

After that, you’re almost done. Although using dnsmasq makes step 2 relatively simple, the difficulty of step 1 can range from “trivial” to “you must reverse engineer the wireless drivers.” For the time being, more information (model number and revision) about the Linksys router in question is needed. A DD-WRT table of supported hardware should be able to assist you.
Oh, and all of this assumes that your idea of “access point” is anything along the lines of “a way to link a computer with a wireless ethernet card to the network,” rather than “any sort of walled garden setup.”
More information can be found on the DD-WRT wiki, but the basic concept is to disable the WAN, disable DHCP, and connect the AP to your network through one of the LAN ports rather than the WAN port (or use the “Assign WAN Port to Switch” feature).
If you set the DNS and default gateway addresses to your router’s IP address and don’t overlap the DHCP IP addresses you’re serving on the router and access point, you can still serve DHCP on the wireless access point (s). When a network client connects to the access point, this will allow for faster IP address assignment.
