@TF7 I know Tomato works and I already tried it, unfortunately it doesn't have repeater mode, I need to set this up as a repeater with multiple SSIDs.

I was actually going to buy 2 more of these routers if I can make it work with DDWRT, otherwise I may have to continue looking for a different router.

@KrypteX, thanks for reopening the ticket

If your intention is to use these in a repeater mode you would be better served to use dual band routers.

in DD-WRT, Services / USB / Core USB Support: Enable
then wifi working!!

@ddaniel51 - I know, but I don't actually need the speed, I need something which can handle a large number of devices at quite a distance and won't cost me an arm and a leg, the Internet connection that this is sharing out is only 15mbps

@KrypteX - enabling USB Core Support has indeed fixed the problem.

The moment I disable USB Core Support, Wifi drops, as soon as I re-enable USB, the signal comes back. So the issue is definitely related to this. Wifi also still works after rebooting.

Thanks for your help everyone!

Hopefully this will help others with RT-N18U Wifi problems. Looks like just enabling USB core services still may not work for all builds.

I have since bought a second N18U and spent 2 days trying to figure out why I was having issues with the Wifi connection dropping off after about 20 seconds on the new device.

I finally noticed that the Firmware on the two routers was slightly different, the one on the router that was working had "std" (standard) after the version name, the one that was having issues didn't have that.

I flashed both routers using the Asus recovery tool from within Windows, I can't remember where I downloaded the non-std image from. I then flashed the the "std" builds through the Webinterface and after enabling USB services both routers are working like a charm.

This is where I got the working std build from: ftp://ftp.dd-wrt.com/betas/2015/07-09-2015-r27506/asus-rt-n18u/

I bought router yesterday and have flashed it with the lastest dd-wrt firmware. Same issue on DD-WRT v3.0-r27734 std (08/24/15). And yes, it works with enabled Core USB Support. Thanks to DINKHo and this forum

[gdl_wrt_rookie]

can confirm fix with USB Core works!!! And that, also with this version DD-WRT v24-sp2 (05/27/14) std - build 24160M.

thanks again

Another confirm for wifi fix by enabling USB core in build 24160M. Follows my experience:

1.- Unboxed brand new Asus RT-N18U.
2.- Flashed DD-WRT build 24160M.
3.- Setup router for my network. Worked fine for about 1 week, nice wifi coverage.
4.- Suddenly router hanged, no wifi, no wired, nothing. Switch router off/on didn't help.
5.- Reflashed again same image DD-WRT build 24160M
6.- Router recovered. For some reason, reflashing did not kill my former configuration, all settings preserved (is this normal!?)
7.- All working fine, except very weak wifi signal.
8.- Enabled USB core, immediately got full power wifi signal.

It is working fine for the time being.

Here is my system information from the 'status' tab after reflashing:

DD-WRT
Router Model
Asus RT-N18U
Firmware Version
DD-WRT v24-sp2 (05/27/14) std - build 24160M
Kernel Version
Linux 3.10.40 #2701 Tue May 27 05:52:37 CEST 2014 armv7l

Cheers!

Hi Guys, you saved my life. Thank you!

Hi Guys,
today I bought an RT-N18U and flashed v3.0-r28586 std (12/23/15).
I set it up without problems, USB NAS is working, routing is okay and so on.
Except wifi. When I try to connect my mobile it gets till "obtaining ip address" and that point the router reboots...
Any idea?
Thanks in advance!

Upgraded but wifi still do not work, i.e. 24% signal in wifi Explorer. Router 10cm from computer.[/img]

What can I do?

[Malachi]

Upgrade to a new build. The one you are using is old.
