Output Power

You can use these figures to come up with what Tx power would be best for you. As factory lists it at a max

of 20dBm, then a setting of 100mW could be used as 20dBm = 100mW, 17dBm = 50mW, and so on.

Initial Flash

Linksys_E3000

Initial Flash 2

Also reference this post regarding the newer nv60k.bin for Linksys E-series. Be aware that some E-series use

nv60k, and others use nv64k.

This guide also applies to units converted to an E3000, running Linksys firmware.•

Read all required reading sections of the Peacock announcement:1. Disconnect all cables and wireless clients.2. As a precaution, USB disks should be removed before flashing.3. Do a Hard reset or 30/30/30 on router.4. Connect 1 Lan cable to pc doing the flash.5. Log into Web Interface and flash the firmware E3000 Initial Flash Trailed Build6. Wait AT LEAST 5 minutes until WLAN (Wireless LAN, not WAN) light turns on.7. Power cycle by unplugging E3000 for 30 secs.8. Plug E3000 back in and wait about 5 minutes until it finishes booting.9. Do a 30/30/30 reset on router.10. Wait 3 minutes and log into web interface.

Upgrade in DD-WRT

AFTER FLASHING THE TRAILED BUILD, only use the following builds OR YOU WILL BRICK THE

e3000:

For builds before svn16773, ONLY USE e2k-e3k.bin builds• For builds since svn16773, ONLY USE an E3000.bin trailed build• If running an E3000.bin build since svn16772, you can upgrade using E3000 (trailed) or nv60k builds• See Where do I download firmware? for links.•

To flash an nv60k build (that replaces e2k-e3k), you must flash a trailed E3000 build from svn16773

or later before nv60k. Do not flash directly from e2k-e3k to nv60k!

To flash another e2k-e3k build such as 15692 (must have e2k-e3k in the file name), follow

these steps.

♦

Download the desired e2k-e3k or e3000.bin trailed build2. Hard reset the router, then login to the router at 192.168.1.1.3. Go to the Admin->Firmware Upgrade page and flash the downloaded file.4. Wait AT LEAST 5 minutes until the WLAN light turn on, then unplug power on router and wait 30

seconds.

Power up and wait 5 minutes, then hard reset again6. Wait until it finishes booting, log into web interface, set user/password, and set up DD-WRT

Clear your browser cache if the web login does not display.♦

e2k-e3k and nv60k

Any build past 16773 requires a different build, rather than e2k-e3k, for subsequent flashing. In order to use

one of these experimental builds, you must ALREADY HAVE dd-wrt installed on your router using the

instructions above, following the steps in the Peacock announcement note 1.

Linksys_E3000

Upgrade in DD-WRT 3

The first Eko -nv60k build is 16773; the first official BrainSlayer -nv60k build is 16785. If you have a

pre-16773 build on the router then you can load either of BrainSlayers 16785 or 16994 builds with file name

ending in e2k-e3k, flashing any those files will be the step stone bringing you over to -nv60k type builds.

16785: ftp://ftp.dd-wrt.com/betas/2011/04-09-11-r16785/broadcom_K26/dd-wrt.v24-16785_NEWD-2_K2.6_big-e2k-e3k.bin♦ ftp://ftp.dd-wrt.com/betas/2011/04-09-11-r16785/broadcom_K26/dd-wrt.v24-16785_NEWD-2_K2.6_mega-e2k-e3k.bin♦ ftp://ftp.dd-wrt.com/betas/2011/04-09-11-r16785/broadcom_K26/dd-wrt.v24-16785_NEWD-2_K2.6_std_usb_nas-e2k-e3k.bin♦

•

16995 is the last dd-wrt build with upgrade files of e2k-e3k type, all upgrading thereafter is done with -nv60k

type files.

Kong Build

Kong 22000++ is a stable, reliable, recommended large build for the E3000 without the Heartbleed

vulnerability. You can (only) upgrade to Kong from DD-WRT. (There are no trialed Kong builds.) Two

versions are available:

DLNA (recommended for home users)• VPN (recommended for office users)•

(Easiest way to rip minidlna is flash the DLNA build then

cp /usr/sbin/minidlna /tmp/minidlna.conf /mnt

and then flash the VPN build.)

K3.x upgrade

To install K3.x the first time, follow these steps using these EXACT builds, otherwise it will soft brick the

E3000.

Start with a hard reset, then load from the GUI (Admin->Firmware Upgrade):1. K2.6_21676_mini_e3000, wait 5 minutes, hard reset, then load from the GUI:2. K2.6_21676_mega_nv60K, wait 5 minutes, hard reset, then load from the GUI:3. K3.x_21676_mega_nv60K, wait 5 minutes, hard reset4. Now any newer K3.x_mega build can be flashed from the GUI (use the trailed build for recent builds)5.

Build Information

Brainslayer added E3000 support starting from 14929 kernel 2.6 (in the broadcom_K26 folder).

Also it has been asked about the builds with e2k-e3k name in them, these builds when already running dd-wrt,

you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed

build (build with the unit only name in it) linked above.

Useful Tips

Cooling can be very important for E-series routers, due to the lack of airflow. It can affect

performance and wireless stability. An easy mod to improve airflow under the unit is in this post by

buddee.

If you experience disconnects from the Internet/Network with this router feel free to try the following

settings:

•

Wireless > Channel > Ch 161 (5GhZ)

Wireless > Channel > Ch 9 (2.4GhZ)

Wireless > Security > WPA2 Personal - AES

Wireless > Advanced Wireless Settings > Beacon Interval: 75

Wireless > Advanced Wireless Settings > Fragmentation Threshold: 2306

Wireless > Advanced Wireless Settings > RTS Threshold: 2307

Security > Firewall > Block Anonymous WAN Access <--- Uncheck

Wireless-N Configuration

From the Wireless-N_Configuration wiki: AES security is required for 802.11n, as TKIP will force 802.11g.

AES+TKIP is also allowed, but only WPA2+AES is recommended.

Printing

Printer Sharing gives a general description how to configure the router to connect a printer on the USB port.

However it describes too much and things that are not needed or even not working for the E3000 router.

Following procedure works with firmware DD-WRT v24-sp2 (12/24/10) mega, the latest version at the

moment of writing.

So here a more specific description how to enable printing.

On the web interface of the router (http://192.168.1.1):

Enable "Core USB Support", "USB 1.1 Support (UHCI)", "USB 1.1 Support (OHCI)", "USB 2.0

Support", "USB Printer Support" on the Services tab (all items under "USB Support" except for "USB

Storage Support"). Note that the router did not recognize my printer if I left the USB 1.1 drivers

unselected. This even though the printer supports USB 2.0.

•

It is *not* necesary to enable JFFS2 support via Administration, Management• Check that Secure Shell is enabled via Services, Service. SSHd and Password Login must be enabled•

Linksys_E3000

Printing 5

Connect your printer to the router• Reboot the router via Administration, Reboot Router•

Via an ssh client (for example putty under Windows) connect via SSH on port 22 to the router:

login as: root• password: <your password that you use to login to the web interface>• check if your printer was recognized:•

root@my-ddwrt-router:~# dmesg | grep usb

usbcore: registered new interface driver usbfs

usbcore: registered new interface driver hub

usbcore: registered new device driver usb

usb usb1: configuration #1 chosen from 1 choice

usb usb2: configuration #1 chosen from 1 choice

usb 2-1: new full speed USB device using ohci_hcd and address 2

usb 2-1: configuration #1 chosen from 1 choice

usblp0: USB Bidirectional printer dev 2 if 0 alt 1 proto 2 vid 0x047E pid 0x1001

usbcore: registered new interface driver usblp

This indicates that a printer is detected on the USB port

And at last enter•

This also indicates that a process p9100d is running looking at port /dev/lp0 which is a printer port

You don't have to install anything via ipkg or any other script. Everything is installed by default. So if

you don't have the expertise to ssh to your router, don't despair, it is only to make sure that your router

recognises your printer on the USB port.

•

To install the printer under Windows, use the following procedure:

Windows 7

Open Control Panel, Devices and Printers• Choose Add a printer• Add a local printer• Create a new port• Type of port: Standard TCP/IP Port• Hostname or IP address: 192.168.1.1• Make sure that the checkbox to query the printer and select a driver is not checked• Wait until the detection is done. It will say that the device is not found. Don't despair• Choose Custom and then click Settings• Make sure that Protocol Raw is selected and Port 9100 is entered. That will be proposed.• Leave all other settings also as they were and press OK• Click Next.• Choose the printer driver for your printer.• Click Next• Give your printer a name• You don't have to share the printer• Next• You can set it as default printer• Finish•
