I have just updated recently my wzrhpg450h to latest firmware (wzrhpg450h-pro-v24sp2-18795.zip)
Unfortunately my Epson SX525WD after router update cannot connect to it anymore. there is no any specific error just information that the password to ssid is invalid.
other devices are working correctly. when i have restored previous verion - problem was gone!

I am having same issue with my Epson WP-4540 Printer. It worked fine with the older DD-WRT firmware. Now that I upgraded to DD-WRT v24SP2-MULTI (03/21/12) std (SVN revision 18795), The printer refuses to connect.
Everything else works fine, but the printer keeps telling me that the entered security key/password does not match the one set for the router/access point.
Problem is that it is in fact the right one. So something else is going on.
If I revert to the older DD-WRT firmware (which I saved), it connects. If I use the new User Friendly firmware, it connects. If I go back to using the newest DD-WRT, it refuses to connect. :(
Anyone know what might be going on?

I would really like to get this solved. I cannot use the User-Friendly firmware as there is no IPSEC VPN Passthrough support.
The older DD-WRT had too many issues with dropping clients and had terrible throughput.
The newer DD-WRT has improved the throughput speeds and seems to provide more reliable client connections, but refuses to connect at all to a couple of clients, including my epson printer, and one Dell D630 laptop with an Intel Wireless WiFi Link 4965AGN.
At this rate I'm just about ready to toss this router and replace it with a different brand altogether.

I had the same problem with the new firmware (18795) on a 450H and an Epson Workforce 633.
Downgrading to 17140 (obtained from ftp://184.108.40.206/) fixes my printer problem.
I would say I'm surprised, but if they held a contest for who writes the worst software, router manufacturers and printer manufacturers would both be up there... :/

Are these printers working through the USB port on the unit or are they connecting wirelessly to the router?

Today I finally re-flashed my WZR-HP-G450H to firmware: DD-WRT v24SP2-MULTI (10/31/11) std (SVN revision 17798).
This firmware had issues dropping connections (drops about every 20-30 minutes) to my daughter's Dell Latitude D630 Win7 Home Premium (x64) running Intel PRO/Wireless 4965AGN (802.11a/g/ Draft n) Mini-Card.
It also drops my wife's Lenovo G560 laptop, also with Intel 4965AGN, (Win 7 Home Premium (x86)
Funny thing is, when I upgraded to the current version (18795), those laptops also would not connect to the Wireless.
Now, back to 17798, they connect, even though they drop (a lot), it is almost reliable.
I did not have these issues with the "User Friendly" firmware, but that firmware does not support IPSEC VPN Passthrough, which I need for my work.
All-in-All, I am now looking to replace this router and will probably not buy a Buffalo product again after this.

I have a similar, but slightly different issue, with a HP 3050 J611 printer connecting wirelessly to my WZR-HP-G450H router with dd-wrt build 18795 installed. The printer gives all indications that it should connect. It recognizes the SSID, can determine the transmit channel, even knows that it is using WPA2-AES. However, when it get to the last stages of connection it gets an error that MAC filtering is on, which it is not. According to HP, it is a default error that means something is incorrect but the printer does not know what it is.
I have five other wireless devices connected to this router and all of them connected with no issues.
When I switch the router to the User Friendly firmware, the printer connects without any problems. Also, when I bring out the router the 450 replaced, it connects to it just fine.
The printer is wireless N and I have tried all the different combinations that the WLAN can be set to. 40Mhz, 20Mhz, different channels, and B G N combinations but nothing seems to work. Also, took a look at advance settings but did not see anything that might be the problem.
I’m at a loss as to what to try next.

Similar problems w/ Epson Workforce 845 multifunction printer. Solution appears to be with the AES/TKIP differences and/or having multiple encryption algorithms on the same network. With DD-WRT 18795, the switch to only TKIP fixed the Epson printer issue (and clearing of Epson to default before relogin). Some issues now with Apple/Hon Hai network chipsets. Seriously considering revert to old Buffalo DD-WRT 17140 or their non-DD-WRT software.
