networking - E3000 as repeater (bridge?) for Motorola DOCSIS cable modem

    I'm trying to use my E3000 as a bridge/repeater to extend the range of my cable modem (Motorola DOCSIS 3.0).

    To that end, I flashed it with DD-WRT firmware.

    1. I'm not clear if I want "Repeater" or "Repeater Bridge" ... I just want to extend wifi range (like WDS) ... ideally with same SSID, but not dealbreaker.

    2. I flashed the "trailed" version (dd-wrt.v24-14929_NEWD-2_K2.6_std_usb_ftp-e3000.bin) ... and it's "sort of" working. But lots of dropouts, losing connection, and SLOW bandwidth.

    3. There are many threads here about different firmware versions, and the order in which to flash them, and I'm thoroughly confused. Should I flash a newer firmware?

    4. The E3000 GUI shows 2 physical interfaces (one for the 2.4ghz and one for the 5ghz, I assume) ... but the guide at http://www.dd-wrt.com/wiki/index.php/Repeater_Bridge says nothing about 2 interfaces. Can/should I configure them both to repeat, each with its own virtual interface?

    5. The guide says to "Match Primary Router" for wireless security ... but the options are different on the Moto modem. Do I use "WPA2" or "WPA2-PSK"? "TKIP+AES" or "AES"?

    6. I don't see any way to change subnet in the TCP/IP settings on the modem, only the IP. It's set to 192.168.0.1; should I be using 255.255.0.0 on the E3000?

    Sorry for all the questions; thanks for any help; really want to get this working!

    dd wrt - Wireless Repeater with DD-WRT
  • pbz

    I have an ATT wireless modem and a LinkSys Router with DD-WRT v24 sp1 installed. I went through the instructions on this page and got to the point that the DD-WRT router can talk with the modem. My goal is to use the LinkSys as a wireless repeater, but for now, while I'm testing, I'm connecting to the LinkSys router via wire.

    From the DD-WRT interface, if I go to Administration -> Commands and run a "ping google.com" I get a reply, so that tells me the LinkSys and the modem are talking. However, if I try to ping google from the computer, while connected to DD-WRT via wire, I get time-outs.

    I followed all the recommendations / steps on the WLAN repeater page. Any idea what else I could try? Thank you!

    EDIT:

    The configuration is something like this:

    ATT modem:
  default gateway: 192.168.1.254
|
(wireless connection)
|
LinkSys WRT54GL v1.1 with DD-WRT v24 sp1
|
(wired connection)
[my computer]
  IP: 192.168.2.128
  default gateway: 192.168.2.1 (LinkSys's IP)

    pbz found that configuring DD-WRT as a Repeater Bridge instead of Repeater allowed him to access the internet when connected to his DD-WRT device via ethernet cable.

    Wireless -> Basic Settings -> Wireless Mode -> Repeater Bridge

    In contrast to Repeater, Repeater Bridge allows for connecting clients to be on the same subnet, in his case 192.168.1.x. Here is a comparison matrix between WDS vs Repeater vs Repeater Bridge features.

    i know its late to answer this post but incase someone else reads it later ill post to get access to the ddwrt just change the ip on either the dd-wrt seperate from the original group range ie. router is 192.168.0.1 ddwrt is 192.168.1.1 or pull up your original router and see what clients are connected and find the ip given for the ddwrt =D
