Setup > Wireless Settings > Manual Wireless Network Setup > Wireless Network Settings > Wireless Band : 2.4GHz Band

Wireless Channel & Visibility Status always display channel 1 & invisible, respectively, but their actual values are the correct channel 9 & visible at which I last set them. When I exit the page, it asks to save, but I never do because I want them where I had them.

(The corresponding 5 GHz band setting displays always do reflect where I last set them.)

Since the DIR-825 is end-of-life, I guess there will be no more updates (even security?), but is this a known bug?

Luckily this is something I can remember and work-around it by simply not saving whenever I'm in there only to inspect values. I just acquired this device yesterday (Hardware Version: B1) and updated from firmware 2.02NA > 2.05 (2-part) > 2.09, following the posted update instructions, especially doing a factory restore every step of the way.

[FurryNutz]

Did you clear browser caches after doing a factory reset then setting up from scratch?

[Schmye Bubbula]

^ I did note that in your firmware update instructions, but I think I have caching disabled in my Macintosh Firefox 45.0.1:



...however I just now clicked the Clear Now button, anyway (as well as the other Clear Now button under it — although I would think that there's nothing to clear, the way I have both set-up), and inspected my DIR-825 Wireless Band : 2.4GHz Band settings, but the two offending ones are still not reflecting the actual values.... So you sound like this is not a known bug. I wonder if there is some cache I missed, or some other culprit.

- -
Edit: It occurred to me to try accessing settings in a different web browser, Safari, and lo and behold, the two settings in question display at their correct known values! So it indeed is some cache or something in Firefox that eludes me. Off to google for obscure Firefox caches and such.... Meanwhile, any Firefox users reading this who've been through this before, please chime in.

- -
Edit #2: This Firefox Add-on extension, Cache Disabler, which is supposed to turn-off both the memory cache and the disk cache, doesn't make a difference.

I also tried RAMBack, which adds a Clear Caches command to Firefox's Tools menu, and it churned away for a few seconds, bringing up the spinning beach ball cursor until it settled-down, but it didn't help, either.

Does anyone know how to get rid of these frigging Firefox caches? I've never met a cache that didn't screw me over!

[FurryNutz]

you might fully un-install FF and then re-install. If Safari is working and FF isn't, then try fully re=freshing FF or remove and re-install.

[Schmye Bubbula]

Oh, boy, for Firefox that's like saying, "Re-install Windows, then all of your apps, one-by one." It would take months to get everything back like I had it. I think I'd buy a new router before putting myself through that.... I could try replacing the Firefox app per se with a fresh copy, but that usually doesn't fix things; it's replacing your Firefox Profile folder — in which resides all your Add-ons, prefs, etc. — that really constitutes a fresh install, and causes the aforementioned pandemonium.... And Safari caches like gangbusters, too — I'll bet it wouldn't be long before the same problem reared its ugly head in that web browser, too. It's caches and their evil, sociopathic programmers that are behind it all.

I found this support article that tells how to "Reload (Override Cache)" a webpage, but it didn't help with my DIR-825 settings page.

Hold the presses! I just tried a launch of Firefox in Safe Mode (disabling all Add-ons), and my DIR-825 settings page came up correctly. So I guess I have some extension conflict. I'll try an  extensions conflict isolation binary search (relaunching Firefox repeatedly, disabling half the extensions at a time) to narrow-down the culprit, and report back here my findings.... It's the least I can do for the other Firefox users amongst us, and a lot easier & faster than the aforementioned deletion of my Firefox Profile folder and rebuilding my environment from scratch!... You know, our web browsers are like their own whole operating systems, in terms of complexity!

Stay tuned, this will take a while.

[FurryNutz]

I've seen this before with some FF add-ons. I ended up backing up my book marks and removing FF fully then re-installing. Sometimes having too many add-ons can cause problems.

Try Opera as well...

[Schmye Bubbula]

Found it!! (with my binary search)... It wasn't a cache issue, after all.
The culprit is the password manager, LastPass 3.3.1.

And you'd better believe that I run eleventy-umpteen other extensions! I'm surprised that it wasn't one of those more exotic ones.

It's funny, I've noticed all along that after every time LastPass fills-in my DIR-825 settings password for me, when I click the Log In button or hit return, it looks like it then concatenates it again to the end of the first instance of the filled-in password, but settings doesn't reject it and logs right on in. Then the LastPass sheet comes down and asks if I want to update what it thought was my changed password (even if DIR-825 settings didn't see it as changed — must have slipped-in under the wire before LastPass changed it), so I took the workaround of telling LastPass not to ask that any more for future logins to that settings page. That may not have anything to do with my problem, but it does at least show that LastPass is doing some funky things behind the scenes.

Now it's a matter of going through the various & numerous LastPass preferences and options, and if changing one of those doesn't account for it, I'll take it up with LastPass tech support.

[FurryNutz]

How about letting FF log in instead of this add-on? 

Glad you figured it out.

[Schmye Bubbula]

If I remove the login entry within LastPass for the DIR settings page, and tell LastPass to never ask whether I want to save the password in the future, my problem does not occur with those two fields' display in the other screen not reflecting the actual state of my chosen channel & visibility.

The business I described earlier about the DIR login screen's password field appearing to add the password twice in succession when I pull the trigger occurs whether LastPass is out of the picture and I let Firefox's native autofill occur, or even if I disable Firefox's autofill, too, and just type it in. False alarm on that; it looks like the DIR login screen is doing those visual machinations, i.e., making the length of the bullet-text string double in size upon entry.

So I've narrowed it down to the mere presence of a login entry in LastPass for 192.168.0.1 associated with the at least two wrong-reading fields in:
Setup > Wireless Settings > Manual Wireless Network Setup > Wireless Network Settings > Wireless Band : 2.4GHz Band > Wireless Channel & Visibility Status

By the way, is there a way to logout of the DIR settings page? I can't find one; I have to wait for the timeout to log me off.

- -
Edit: Wait a minute, I was playing around with LastPass this morning, and when I again let LastPass save my password for 192.168.0.1, it stored as gibberish text. I had forgotten that it had done that before, and I had to edit the gibberish back to my real password to make the DIR login screen accept LastPass's auto-filled-in entry, and I thought it was just a fluke.

Does the DIR login screen encrypt the password before sending it to the router? That would explain why the bullet text appears to lengthen when I pull the trigger.

And looking around in my settings, I notice that my admin & user passwords are gibberish text. (I have a Firefox extension that shows my real password text behind the bullet text when I roll my mouse pointer over the text field.) The passwords are getting encrypted, aren't they? But the next time I save my settings, I'm afraid that the gibberish text will become my password. I'm getting confused — did the router put gibberish text as the password, or did LastPass?

[FurryNutz]

I recommend NOT using this FF add-on as it seems to be causing problems. I use FF internal PW storage when I need to save a PW.

[Schmye Bubbula]

I very well may have to switch from LastPass to, e.g., 1Password, or just rely on Firefox's (less-secure) native password manager, as you do.

But as long as I don't let LastPass save passwords for the router, and instead let FF internal PW storage do it, or just type it in manually, there seems to be no other problems. I'm going to keep using LastPass for a while and keep an eye peeled for other any other anomalies, and let you know if any occur.

What I'm seeing behind the bullet text as gibberish text for my passwords in TOOLS > ADMIN must be the hash generated by the router for security. That would account for me being able to save the settings either with typing-in my password again replacing the gibberish, or with the gibberish as-is and still being able to login with my regular password.

Is there a way to logout of the DIR settings? I can't find one; I have to wait for the timeout to log me off.

[FurryNutz]

No log out feature. Should auto log you off with in 3 minutes I believe.
