Just common question. Have you guys checked that the md5sum of the image you are trying to upload matches with the one that is reported 

[Geraner]

Installed the Web-Admin for the OpenWRT firmware.
Then I uploaded the orignal D-Link firmware again. Finally the router is working perfectly again after one week troubles with the open-source firmwares.

In the meantime I have bought a Netgear WNDR3700 and I'm very happy with this product.
I think I will sell my DIR-825 and stick with Netgear instead since the Wifi signal both in the 2,4 and 5 GHz band is stronger than the signal on the DIR-825.

[Geraner]

Just want to update you all.
Went back to the shop with the Netgear router. Keeping my D-Link DIR-825 and running it with firmware 2.01WWB02Build02 från Lizzi55's FTP server.

Stable firmware. Everything is working as it should.
Don't need to mess with any other firmware version so far.

Hey guys,
did anybody get the 5GHz working? I always get

wlan1: IEEE 802.11 Configured channel (36) not found from the channel list of current mode (2) IEEE 802.11a
wlan1: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-1)

by wifi and by hostapd itself. But:

root@OpenWrt:~# iwlist wlan1 chan
wlan1     9 channels in total; available frequencies :
          Channel 36 : 5.18 GHz
          Channel 40 : 5.2 GHz

Does anybody know how to get this working?
Btw: iw reg set DE did not work for me, does anybody know why?

Using Kamikaze r19497 from 3rd feb, but it was the same on the releases before. dir-825 b1.

Hey guys,
did anybody get the 5GHz working?

Do these ( https://forum.openwrt.org/viewtopic.php?pid=101782#p101782 ) instructions help you?

Thanks for that, now I got some changes in the available channels. But the main problem remains, there is still this "Hardware does not support configured channel" although it apears in iwlist chan and iw list.

[blackmole]

I got it all working now with mactallas great help, thank you very much!
Here is what I did:
- installed crda
- added "export COUNTRY=US" to /etc/profile
- added "option 'country' 'US'" to the 'wifi-device' section in /etc/config/wireless
- chose a channel which is allowed in US and DE, see here
- removed "option 'hwmode_11n' 'a'" and changed "option 'hwmode' '11a'" to "option 'hwmode' '11na'" in /etc/config/wireless

[gerhard]

another question - does anybody of the OpenWRT-users use timebased activation/deactivation of wireless or know if  OpenWRT can handle this. I find this a quite useful feature (both for security reasons and for powersaving) and would wan't to miss it in case I switch to OpenWRT.

[ea_umea]

There is a beta of the next OpenWrt release out now. I read that some packages for getting the wireless and usb to work are not included in the default image, but just download the imagebuilder and build an image yourself for this router and it will work from start. If you need more space for own packages see this guide, http://wiki.openwrt.org/doc/howto/rootfsonexternalstorage and include the packages needed using the imagebuilder. I am running this version now with a 2GB usbdrive connected for rootfs and it works as expected, the firmwares i tried from D-Link was never close to as stable as the current setup.

[JoeSchmuck]

So what's the current status on how OpenWRT is performing on the DIR-825 Rev B?  I have tried DD-WRT but honestly the wireless power leaves a lot to be desired.  The stock firmware is much better in that respect.

OpenWrt works pretty nicely with this router, far better actually than the extremely buggy DD-WRT. Thanks to the Ath9k driver (much better than the cr*ppy madwifi used by DD-WRT) I'm getting the best signal strength than any other firmware, including stock v2.02. I did however experience many bugs such as the non-working wlan leds (minor), and the infamous "Deauthenticated due to local deauth request" issue.

The problem with OpenWrt and DIR-825 is that very few people are actively working fixing bugs for this specific combination and AR71xx in general. Same as any opensource project, code maintainers are merging untested patches that fix a specific router but break others. That's why I always revert to stock firmware after a while.

[JoeSchmuck]

Yea, I really like DD-WRT on my WRT54G routers.  It works great, but then again that was a main target of DD-WRT.  I haven't tried OpenWRT on my DIR-825 but maybe in a few months after seeing a few more software releases pop out.  I'm looking to replace one of my WRT54G routers with this D-Link router so I can experiment on the 5GHz band.

Hi

Hey, how's it going?  I hope the instructions on the DD-WRT are helping.
