I would suggest you reboot the modem first. Nothing bad will happen. It is the same as if the power in your house went out and came back on. It is meant to get an IP by itself. As for the ISP customer service staff, I would suggest you to just be patient with them. They are mostly reading from a script and must go step by step through a procedure. The first thing they will often tell you to do is to power off the modem for 30 seconds and power it back on.

hi ian5142,

thanks for the suggestion.  The final conclusion I got is that 30880 & 30826 are not stable at all for v7, and as I find out v7 is running a totally different hardware than v8.  SOC on v7 AR7241-AH1A vs v8 AR9341.  

I'm uisng 21061 for its stability on the web interface, however, what I'm trying to do is to have ssh server running correctly on 841, which is a problem in fw 21061...

So my question is which fw version is best for AR7241-AH1A with everything working, especially SSH Razz ?

Why do you say that 30880 and 30826 are bad on the v7?

I don't see anything on the svn timeline: http://svn.dd-wrt.com/timeline

or as far as I can tell anything in either build thread:

Hi guys,

I just bought the v11 and it seems locked, I can't do anything at all (it seems to be a new regulation or something like this) do you have any idea about a way to unlock it in order to install dd-wrt on it.

Thanks a lot

You will need to use TFTP to bypass the firmware upgrade screen.

Get a TFTP Server software such as TFTPD32 or TFTPD64: http://tftpd32.jounin.net/tftpd32_download.html
Make sure to get the installer it makes it easier to use.

Download this file: ftp://ftp.dd-wrt.com/betas/2016/11-14-2016-r30880/tplink_tl-wr841ndv11/
(You want either the factory-to-ddwrt or factory-to-ddwrt-US) The US is if the router was bought in the US.

Rename the file according to this page: https://wiki.openwrt.org/toh/tp-link/tl-wr841nd#tftp_recovery_via_bootloader_for_v8_v9_v10_v11

Follow the steps listed there. It should work.

The 841nd v8 has too small of a flash size to offer VPN services. You will need a router that can run a standard or bigger build (>= 8mb flash size).

Look at something like the TP-Link WR1043nd v2 or higher. (v1 is faulty hardware, avoid at all costs).

Or if you want to go broadcom, get an Asus N66U.

If you want to know if a router will support VPN on dd-wrt, just check the build size. If it is bigger than 4 mb (4000 bytes), it most likely will.

Hi! I've just bought WR841N because of it's dd-wrt compatibility, but it happened to be Version 13.0 and can't seems to find the dd-wrt firmware for it. Is there ant chance of reflasing this router to dd-wrt?

Ciao
I had the same issue on my router v11
I fixed installing a patched firmware done by user NeDark

My bundled firmware was:
3.16.9 Build 160325 Rel.62500n
With it I was receiving the same error message
SO i founded a patched firmware:
3.16.9 Build 150616 Rel.52099n (attached to this post)
With it I was able to install later a DD-WRT firmware Very Happy

Hello, I just successfully updated my DD-WRT WR841n-us firmware from version r29974 to r33525. Is the startup script to enable communication between lan ports still necessary with the latest firmware?

Thanks!
