Posted: Mon Jan 10, 2022 9:03 Post subject: Wireless Connection Stops Working on R7800 after Upgrade
I recently upgraded my R7800 from DD-WRT v3.0-r33010M kongat (08/09/17) to DD-WRT v3.0-r47976 std (01/06/22) - my wireless connections stop working randomly and I need to reboot my router. Sometimes it's the Guest network, sometimes it's the main. Additionally, when I was trying to trouble shoot everything the Web GUI interface that shows up when you go to 192.168.1.1 stopped working and I needed to reboot manually.
When I upgraded from r33010M to r47976 I didn't clear all my old settings out, could that be the problem?
Before I upgrade to the latest build (r48075 ) and deal with the hassle of starting fresh, could you guys please review the attached screen shot of my wireless settings. Is there anything incorrect there?
dd-wrt internals from 5 years ago are WAY different than what dd-wrt is NOW. So a factory reset is a MUST.
I personally recommend you treat the 5Ghz wireless as your primary and 2.4ghz as your secondary/fallback. Make them both different names like
5Ghz would be "I am Jacks Wireless network"
2.4ghz would be "I am Jacks Legacy" (sounds awsome not gonna lie)
my network is something like 5ghz "GAKS wireless" and 2.4ghz being "legacy" so now you know why I said what I said in my suggestions.
-ANYWAY-
Start with default settings for wifi. Adjust ONE SETTING AT A TIME and test it before changing another setting. Each wireless environment has its own needs and may most likely work better with default settings then to mess with something thats already working fine. _________________ For people who are new to the dd-wrt forums >> http://www.catb.org/~esr/faqs/smart-questions.html#rtfm

I agree about a reconfiguration after such an old build.
This has probably been asked before but if the settings from that sticky are so good why aren't they the defaults? Is it just a matter of compatibility?

Yes, it's done to assure you can connect to wifi on the router. It's the most basic/generic settings to assure broad compatibility on initial loading. _________________ FORUM RULES
@xxxxts, I did similar, old to new, however on the Jan. builds I've had my wlan0 stop working on my Linksys EA8500.
I've done several factory resets, and the problem remains.
I'm not trying to hijack this thread, but wanted to provide some troubleshooting tips to work together to solve.
I've SSH'ed in and done a erase nvram && reboot and noticed not all my setting reset. I then did 3 factory resets in a row via the Gui, reset, reboot, new pass, (x 3) My WDS Mac address settings unchanged, so at least the WDS Mac addresses are not cleared with a factory reset.
After a reset I would add a password, reboot, then go into status, wireless, and my wlan0 would say channel "unknown". I've tried auto, multiple channels, and multiple different settings, but I can not seem to revive wlan0 on the Jan firmware levels. I'm going to attempt to backlevel to an older firmware level and post my results. But take a look at your status, wireless and see if that helps you troubleshoot.
I reverted back to Firmware: DD-WRT v3.0-r47074 (07/20/21), and my wlan0 now shows a channel under Status->Wireless->Wlan0. The 2.4 wireless started working again, where before on the Jan versions it would not work at all regardless of channel settings.
