Basically, i bought a netgear WNDR3400 about 3 weeks ago, but couldn't find a WRT for it, found one yesterday installed, followed every step 30-30-30 etc etc.
But now the netgear doesn't give me any internetz lol.
i know its not my modem because im currently talking to you from it.
I have no clue what could be wrong, guessing at IP's but i don't know any help would be appreciated.
its acting like its not getting any connection though
*if i click on internet access and trouble shoot it just says no cables are attached*
when literally 5 minutes before i swopped to it the same setup of 1 router to it worked. Just with the netgear firmware
Did you do a hard reset after the flash to dd-wrt?
Can you access the dd-wrt web interface on the router?
Does your router show any WAN IP on the Status > WAN page? If not try power cycling your modem and the router, modem first.
If it does show you have a WAN IP, when you go to Administration > Commands can you ping any websites on the internet like google?

I did a hard reset, before, After and while to see if i did it again it would fix the issue.

Yes it does show a Wan IP 192.168.1.4
this is a simple easy fix
dd-wrt defaults LAN IP to 192.168.1.1 and gives out 192.168.1.100-XXX the problem is you have the same net as your upstream...
so the fix is change your LAN settings, LAN IP on the main page.... to 192.168.5.1 save/apply settings... then reboot the router then reboot your pc... all fixed.
Cheers Fractal. reverted back to the custom firmware for now when i get some free time thursday i'll swop back.
College and work so no time, *hense the long response time yesterday lol*

I just flashed my tp-link Archer C9 with a DD-WRT. Got everything setup and most of my devices online. But for some reason my Samsung S9 cant get any network connection. I can connect to the router fine and it is assigning me a 192.168.1.111 address. What should I look for as possible reasons for not being able to connect.
