dd-wrt flash to N66U
Hi Philwoz98.
Let me preface this with the fact that in no way am I a techy. I have a lot of years' experience but not a techy and the guys on here just blow me away when reading some of the stuff.
However, I have the N66U and successfully flashed to dd-wrt. So here are the steps I took.
(as an addendum, earlier versions of dd-wrt needed CFE 1.0.3 but I read that it doesn't matter with K3 builds but will only work with the N66U (B1) version).
1. Made sure that my N66U firmware was the latest.
2. Did a 30-30-30 reset - held the WPS button for 30-seconds, unplugged router whilst still holding the WPS button for another 30-seconds, plugged in the router and still held the WPS button for a further 30-seconds.
Went for a coffee while the router settled down.
3. Flashed to Merlin firmware FW_RT_N66U_3004374979.trx (to try it out)
4. Did the 30-30-30 reset as described in 2.
Let router refresh itself and had another coffee.
5. Flashed to dd-wrt dd-wrt.v24-21676_NEWD-2_K3.x_mega_RT-N66U.trx
6. Did the 30-30-30 again.
Had another coffee while the router settled down.
7. Flashed to dd-wrt.v24-21676_NEWD-2_K3.x_mega-nv64k.bin
8. Flashed to dd-wrt.v24-22118_NEWD-2_K3.x-big-RT-N66U.trx
You may be able to go 1-4 and then straight to 8. I went to 5,6 and 7 to see these versions of the firmware but doing all of this did give me a working dd-wrt N66U.
In the end went back to Merlin's firmware as I don't need all of the bells and whistles and it leaves me working comfortably within my own abilities and needs.
Please, please, please, seek other advice as someone with a lot more experience may advise otherwise.
Best
Paul
