Wireless repeater setup with dd-wrt firmware

DD-WRT is a third-party/open-source router firmware distribution that gives the user more control over the router’s hardware features. This is in contrast to factory firmware, which only supports a limited range of functions. DD-WRT, which is based on the Linux kernel, is only constrained by physical constraints such as flash memory capacity, RAM size, and CPU clock speed, much like a typical personal computer.
Open-WRT (another open-source router firmware project) began in 2004 as Linksys-based firmware that was installed on top of a linux distribution with customizable software packages. DD-WRT (>2004) began as a Linksys-related firmware based on Sveasoft’s Alchemy firmware. The linux kernel is based on the Openwrt kernel from version 23 onwards (2006). DD-WRT is currently attempting to integrate its code base with Open-WRT so that packages can be exchanged.
The DD-WRT firmware (.bin file) for a specific router can be downloaded quickly and easily from the DD-WRT website. For download, use, and troubleshooting, the DD-WRT wiki page is a great resource. The Linksys E3000 and Ubiquiti Routerstation Pro wireless routers’ installation procedures are defined.

How to install dd-wrt on linksys e4200 router

I’ve tried changing the country code to 00 – world, driver default, GB, and US, rebooting the system after each update. I’ve also confirmed g speeds by running a speedtest, and I’m getting capped at around 24Mbps, which is close to the g network’s maximum speed. I’m not sure where to start looking now.
BCM4718A1 is only supported by b43, but b43 lacks any support for HT modes, which are needed for throughputs greater than 54 MBit/s (and no, there is no hope for this to change in the future). If you need more efficiency, you’ll need to find a router that is better supported (there are quite a few nice devices on the used market for rather little money).

Linksys e4200 v 1 as repeater

„DD-WRT is a Linux-based OpenSource firmware that can be used on a wide range of WLAN routers and embedded systems. The key focus is on making handling as simple as possible while still supporting a large range of functionalities within the constraints of the hardware platform in use.“
Important: Make a backup of all important information from the previous firmware. Access data for the provider, WLAN settings, allocated fixed IP addresses, if appropriate, Port-Freigaben, and VPN settings, and so on.
However, I followed Steve Jenkins’ guidelines for setting up my WLAN, My Cisco Linksys E4200 DD-WRT Settings for Max Speed, in order to get the most out of my wireless network.

How to install dd-wrt on your router and boost wireless

I’ve been running the new DD-WRT builds on the E4200v1. The officially confirmed DD builds are typically old, but current betas usually work as well – all you have to do is browse the FTP directories for the new update.
Older builds have significant security flaws, and the (still-old) wiki page’s suggested KingKong-Mod has inadequate IPv6 support, so I upgraded to the K3.x builds. There have been no concerns so far.
Temperature issues resulting from high transmit power are listed on the wiki page, but even with the original setup, it’s very hot. For my application, I was able to run both radios at 18dB (63mW), but the temperature was still reasonable at 19dB (80mW). It appears that CPU-intensive applications have a greater impact than radio.
I also tried OpenWRT (15.05), which is normally my preferred firmware, but I was only able to get 5GHz WiFi up once and it was not very reliable (kind of roulette if it booted correctly). Apart from that, it worked fine, but I wouldn’t recommend it to anyone, particularly beginners. It’s not easy to install custom network modules and configure the kernel.
