Netgear WNDR3700v3

Flashed successfully with
dd-wrt.v24-23838_NEWD-2_K2.6_big-nv64k.bin
with reset, but Wi-Fi is not working.

Reverted to
dd-wrt.v24-21676_NEWD-2_K2.6_mega-nv64k.bin

Same here, the wifi would work on my 3700v3 only after you manually disable in wireless setting, then enable again, but after reboot wifi will stop working again, this should be a driver problem.


Thank you for your reply. I didn't test disabling, enabling and rebooting, so thank you for your info.

Does anyone know something about CPU overclocking on this router with the latest build? I noticed it is supported but i don't know if it is safe to test it, so i will be grateful for some information.

Never tested but it's an old cpu which came out in 2009 so overclocking might not bring much improvment. Better get a newer model with dual core cpu for better performance such as R7000 or EA6900.

Thank.you. I can say, i'm very satisfied with my WNDR3700v3 running on DD-WRT. There is only one problem that i'm trying to solve - router freezes if i'm copying big files via FTP. I don't know how much can overclocking improve the performance and if it can solve my problem, but on my Linksys WRT54-GL overclocking really improves the performance and speeds.

E3000 working nicely with 23838 so far.

Before getting there I bricked my E3000 at least 10 times by flashing stock firmware and going to K3.X directly, K2.6 23838 first and K3.X 23838 next and bunch of other permutations. What got me there finally:

Flash K2.6 21676 first, K3.X 21676 next and then K3.X 23838.

Both 2.4ghz and 5.0ghz bands working. More importantly for me, USB NAS works with 3TB ext3 drive. I only get 6 MB/s transfer speeds but I think that's all E3000's cpu can handle.

Do you think it is safe to flash my router with K3.X build? Did you recover you device with tftp or jtag?

I definitely can NOT say that it is safe. I bricked my E3000 many times and each time I was getting a short window of ttl=100 ping responses but not long enough to tftp new firmware. So if you can access your router via serial you are in good shape. I actually shorted the flash chip when booting the router (google Eko's pin shorting) which put the router in a state where it expects firmware to be flashed. This is way more riskier than the serial method so try at your own risk.

If you decide to give it a go, I think the best option is to follow the flashing route that worked for me: Flash K2.6 21676 first, K3.X 21676 next and then K3.X 23838. Anything else I tried bricked my router.

There's no need to go to the 21676 K2.6 first. I went through the same fiasco about two weeks ago.

From stock, you can go to 21676 3.x and then to the newer build 3.x. However, if you go straight from stock to 23838, something in the nvram defaults won't get initialized correctly, and it things it's a different router (the wrt54g).

I can do that on mine, but it isn't stable - wifi drops every few minutes and the router reboots after 9-10 mins.
Is yours stable?

Thanks

it;s been relatively stable for me in this short time period. Did have a reboot due to trying to do a large file transfer (8 gigs of mixed sized video files) to my USB attached RAID array(file transfer speed is still slow-4 mb per sec).

as for wifi, not noticing any errors in the sysinfo page thus far. wifi seemed pretty stable in 23720 as well.
