hansg91: I haven't gotten anything reasonable on both 2.4 or 5ghz (B,G,N,AC) with any recent dd-wrt build. I'm pretty fluent with channel selection and how to optimize in different environments, but I can't get stable above-average speeds with the WZR-1750DHP(D). Even Auto channel selection doesn't seem to do it's job, and interference from nearby AP's kicks-in and usually results in less than 50mbit speeds (even though the link rate is much higher). I've done extensive testing with all builds the past few months and most of the results are similar.
For 2.4, I always lock 20MHZ, choose a non-busy-non-overlapping channel, a dedicate the mode to one or two protocols.
For 5G, I pick a high channel (149) and lock it on 80MHZ.
AES/WPA2 of course, and the Advanced settings don't help gain anything substantial, so I leave them alone or tweak only slightly.
Considering the above, dd-wrt doesn't net high performance wifi speeds which are constant. The WZR-1750DHP may perform as expected for an hour or two, but then nearby AP's seem to interfere and kick the transfer rates to less than 50mbit.
I've even tested in quiet environments and get the same results.
Buffalo DD-WRT however (minus a few small bugs) is reliable, stable, performs, and always nets advertised wi-fi speeds.
Current link rates from the few devices I have connected are 433mbit, 433mbit, 144mbit and 1300mbit. All devices are getting full air speed during transfers. Uptime on my WZR-1750DHP is 3 weeks.
To be honest, the Buffalo ware:v24SP2- (06/12/14) std build will net you the best results. (Besides the factory firmware which is fast, but I won't use.. just because).
I know this only shows WAN performance, but here is an iPhone6 test on 2.4ghz, with a 75down/10up connection at about 50 feet. Hits peek rates 24/7 using Buffalo dd-wrt.

Okay so I never expect things to go well. I always assume i'll be stuck with the TFTP Mess or whatever for hours. So I've basically given up and just started with the Hard way. I just spent an hour trying to get TFTP to work to upload and had NO success with it. So i thought I'll give the web front end a try -- BAM no issues at all!
1. 30-30-30 This DID work for me, but I've read sometimes you need to check the Admin Page -> Initilize to factory reset
3. WAIT -- I was watching for the generic wifi signal to pop up on my phone, Then i gave it another 90 seconds after that to have a good margin
4. Refresh your IP / disable & Reenable your NIC or whatever -- Buffalo defaults to 192.168.11.x DD-WRT is 192.168.1.x You need to move over to that IP space.
5. 30-30-30 again... It's a minute and a half, just do it!
6. Connect to 192.168.1.1, Update password, then Administration -> Update Firmware -> Update with the build you want (I don't really know if you need this one I didn't check my build version before I updated...)
7. Done -- that's it -- no TFTP mess or anything! Woo!
To be honest, the Buffalo ware:v24SP2- (06/12/14) std build will net you the best results.
I'm running 06-24-2015-r27435 and my 1750dhpd keeps periodically causing my wireless clients to lose internet connectivity -- the clients are still connected to the 1750dhpd but cannot access the network. The 1750dhpd is unresponsive over wireless too (via GUI or ssh); but I haven't yet tried connecting over physical ethernet when the 1750dhpd goes out to lunch.
Anyway, my tale of woe aside: I intend to upgrade to 07-09-2015-r27506 over the weekend. Hopefully that helps, but based on your findings that the Buffalo provided dd-wrt is best for performance (and others have said range) I'd like to understand how I "downgrade" from dd-wrt.com firmware back to buffalo provided firmware.
I downloaded wzr1750dhpd-v24sp2-23709c.zip from buffalo and would like to be able to fallback to it if needed. But it is my understanding that their firmware is encrypted such that flashing via the dd-wrt.com r27506 web interface won't work?
So how would I go about downgrading from r27506 to buffalo's wzr1750dhpd-v24sp2-23709c?
I've noticed the same problems with interference as scampganter has, but I'm also in a VERY dense wifi neighborhood. At my house I can see 10+ AP's.
What I did was jacked up the transmit power near max. Not the best idea, but without doing that, I couldn't get usable speeds. 5Ghz N still only connects at 144Mbps when 300 is supported. If I use Buffalo firmware, steady 300Mbps. DD-WRT always flops around from 48Mbps to 144.
One thing I also found is that on the 1750DHP the 2.4Ghz G/N signal will mysteriously vanish at random times and stay that way causing all my 2.4ghz devices to have no signal, even though I can still pick up 5Ghz just fine. If I hit Apply in Wireless settings without changing anything, 2.4Ghz is back...
DD-WRT is full of bugs that Brainslayer doesn't care about. The quality of the software is so low compared to years ago I won't be buying another DD-WRT router again. I'll look for something else.

I tried the Buffalo DD-WRT version again after your post and with your settings it does sometime seem faster (even saw more than 100mbit once), but it doesn't seem like a stable connection. At least through speedtest I see a lot of acceleration and deceleration. I tried Buffalo DD-WRT 06/12/2014 and some version I found from april 2014, both seemed to give the same result.
What is your experience with this firmware, is it good? Or just better than BrainSlayer's version? How does it compare to Buffalo's own firmware?
EDIT:
I stand corrected, the dd-wrt from buffalo does seem to be fast with the wireless speed, its running smoothly now! Thanks for your reply, it got me testing again
totay I have try to go back to Buffalo original "userfriendly" software. but it is not possible....the router reboots only after firmware update an the DD-WRT 27734 is also istalled !!!
The original firmware is the 2.24, not the 2.27
via TFTP I can't get any connection !
Someone an Idea ?

[quote="swallick"]Just a heads up: If you want to continue to use DD-WRT on your WZR-1750DHP and DHPD do not flash factory 2.27 (released 2015-04-13) to the device. Per Buffalo, it is not reversible.
Reported thread: [url=http://www.dd-wrt.com/phpBB2/viewtopic.php?p=969215]Buffalo WZR-1750DHP ver 2.27 to DD-WRT Firmware[/url]
According to Buffalo,
[quote]We must limit access due to licensing agreements.[/quote]
You can still move over to DD-WRT albeit a little trickier with version 2.27 basically you need to enable debug options and from there you can access a hidden admin page to upload whichever BIN file you like without validating it for compatibility (RISK ASSUMED).
I will post details on how to do that on the link you provided, PM me if you need more help.

Did any one try this solution;

Reverting Buffalo WZR-1750DHP-EU from DD-WRT firmware to Stock (v2.22)
Just got myself a WZR-1750DHP from Amazon.
Tried the stock firmware, was quite impressed with the performance and features provided, only draw back was SSID2 only supports WEP encryption, and I do want WPA2 on SSID 2.
Was always a big fan of DD-WRT, decided to give it a try, flashed the following two images:
factory-to-dd-wrt.bin then
buffalo-wzr-1750dhp-webflash.bin.
Unfortunately the WAN performance was not very good at all, it's kind of limited to about 30MBps throughput, apparently hardware NAT was not enabled / support on DD-WRT firmwares.
No SSID2 vs slow internet, I've decided to go back to stock.
Procedure for going from DD-WRT back to Stock 2.22 firmware:
(1) Download 23709a (buffalo customised DD-WRT firmware) from Buffalo
(2) Extract the .zip downloaded from Buffalo, locate file wzr1750dhpd-v24sp2-23709a.bin, and update to router, selecting erase all settings.
(3) Download v2.22 firmware from Buffalo
(4) Extract the .zip, and locate file wzr_1750dhp_eu_222
(5) Update firmware from 23709a to EU 2.22. Be patient as the process did take some time, and router might restart several times.
