hello to all we have this problem for months concerning the wifi, either it loses the connection intermittently or impossible to connect at all, this time my iphone in this snapshot remains connected but the android laptop refuses to connect if I restart the router is ok

@Lynx do you has solve the problem for the wireless ?

thanks everybody

Browser based IRC clients are flawed by design, as forward/ back and similar browser-side controls will inevitably break the connection. Decent free (both FOSS and fre as in beer) native IRC clients exist for just about any operating system - and they're worth the 5 minutes to investigate and install them.

I realize this is somewhat off topic, but I was hoping to replace my aging Archer C7 access point with the inexpensive AX202. I've been a very pleased user of the RT3200 so I guess there's at least some commonality as they are both Mediatek based. If I offered to donate an AX202 to a developer would that help in getting patch accepted? [https://github.com/openwrt/openwrt/pull/9690] @daniel

EDIT: Welp they sold out...still I could set a price alert if there's interest.

The issue still exists for me with:

OpenWrt 22.03-SNAPSHOT r19445-19f3ee51a2

And with 'reassociation deadline' set to 20000.

Namely last night my wife said that for both her iPhone and iPad she left it in room, came back to it, unlocked it, and internet didn't work despite WiFi symbol showing until she disconnected from WiFi and reconnected to WiFi. It seems this - loss of internet connectivity after sleep pending manual reconnection - occurs about once every day.

I don't know how to fix this or diagnose the issue. :frowning:. Anyone have any ideas or suggestions?

@daniel any suggestions for cause or things to try because multiple individuals complain about such issues with Apple devices over several threads on this hardware. I realise a difficulty is that there could be a couple of problems not just one problem.

I see no such issues with Android devices or my Windows laptop or desktop.

If someone could build a build without the PPoE offloading patches, that would be a decent work-around for those using this device as an AP only (assuming that PPPoE patches indeed conflict with the connection issues).

I've managed to connect to serial console, and got this:

What's the general feeling, am I better off with 22.03 or using snapshot?

I'm using mine as dumb AP, so really only need stable switch and WiFi.

Wifi has never been stable for me with this router.

Looking for some guidance on repairing OpenWRT on my Belkin RT3200. It had been working fine for a few weeks, also running AdGuard on it. Randomly stopped working, and all settings had been reset, and 5GHz radio is not detected. I attempted to update with 'openwrt-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb' and see if it would correct the issues, and the router still does not see the 5GHz radio, and when ssh'd into it 'auc' does not work like it did before.

Current Firmware Version: OpenWrt 22.03-SNAPSHOT r19228-0877953235 / LuCI openwrt-22.03 branch git-22.083.69105-af8e91c

Is there a different, more stable, version that I can swap to? Do I need to do a complete reinstall of OpenWRT? If so, is there a guide to doing so? I have been flashing through the GUI

My use case is my primary router, 2.4GHz + 5GHz in USA, running AdGuard on the router as private DNS server.

Hello could you try this:
https://downloads.openwrt.org/releases/22.03.0-rc4/targets/mediatek/mt7622/openwrt-22.03.0-rc4-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb

I have this version running in my rotuer

This did it! Thank you!

More specifically, I force flashed the initramfs recovery image, unplugged for 2 mins, plugged back in, it booted into recovery, then flashed this image. Not sure if all the steps were necessary, but my router is seeing radio1 again :smiley:

I feel that WiFi is more responsive on the MASTER SNAPSHOT due to updated mt76. However this is my own subjective feeling and I haven't taken any quantitative measurements to back up my claim.

I first wrote about this issue here:

I'll try to make this concise:

  • In November or December of last year, I used @daniel's image to upgrade to UBI
  • used this build to update to the latest build that same day
  • enjoyed months of completely flawless performance (never rebooted, crashed, or lost connection)
  • About 1.5 mos ago, decided it was time for an update, the gui version of AUC failed, then the SSH version also failed.
  • returned to the DangoWRT github page, and downloaded this image: openwrt-22.03-snapshot-r19338-ae64d0624c-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb. This image had two problems for me,
    • it took some finagling to get the 2.4 ghz network working (5ghz was fine)
    • AUC was not present at all. It's not in Luci, and it doesn't appear to be in $PATH when I SSH into the machine.

I have been using this build ever since, but my wife has been complaining about the 2.4ghz network (which she has to use because her office is too far from the router). Even though her problem could be outside our network, I'd still like to update to a newer snapshot.

My questions are:

  • Why did AUC disappear?
  • Should I install the RC4? Scanning this discussion, it seems like a lot of users are having problems with it. My wife will kill me if the router stops working.
  • Does anyone have a build that they'd be willing to share that has been very stable for them?

Thanks in advance!

Maybe auc is just not included in that build? Install normal sysupgrade file from openwrt or one of the build servers. On the build servers you can even specify what extra packages you want included or install them through opkg package manager later on (software tab on luci or opkg cli). Problem is on snapshot you can only install packages through opkg for that day until there's a new snapshot build as all package are rebuilt towards that new build.

I recently installed openwrt on my Belkn RT3200 following the directions at https://github.com/dangowrt/owrt-ubi-installer#installing-openwrt. Everything booted up ok and I started poking around. I seem to be missing my 5Ghz radio. I then installed a more recent snapshot, no radio. tried installing RC4 - same but I noticed that the version info on the Overview page didn't change.

Tried going between the most recent snapshot and RC4 and no matter what the Firmware version doesn't change in the overview page.

Hostname OpenWrt
Model Linksys E8450 (UBI)
Architecture ARMv8 Processor rev 4
Target Platform mediatek/mt7622
Firmware Version OpenWrt 22.03-SNAPSHOT r19338-ae64d0624c / LuCI openwrt-22.03 branch git-22.119.37115-66994a5

Is the 2.4 Ghz band internet connection disconnecting at times for anyone else? The internet stops working only for this band at times and it's back after a while. Anyway to fix it?

I have same issue, at random times I loose all connectivity. I have same SSID on 2.4GHz and 5GHz and can't actually tell which radio looses the connection. I am running OpenWrt 22.03.0-rc4 configured as "dumb AP", so the load on the CPU/RAM should be pretty low actually.

@nbd Hello Felix, Thank you for maintaining the mt76 driver. Are there any plans to update the mt76 version in 22.03 branch to match the master branch? How do you decide which mt76 commit to use for a specific openwrt branch? I had also asked this question earlier at https://github.com/openwrt/openwrt/issues/9945#issuecomment-1139843095

Every once in a while, I have these moments when I realize how profoundly confused I've been. I didn't know that you could simply install the AUC from the repo. I thought this was one of the main benefits of using the DangoWRT script; it installed Daniel's custom-made AUC. :laughing:

Thank you. I think you've solved my problem.
