Belkin RT3200/Linksys E8450 WiFi AX discussion

Want to confirm HE160/VHT160 is working.
Intel AX200NGW (2x2) reports link speed 2402mbps. iperf is around 900Mbps

To use 160MHz (HE160 or VHT160), channel must set to any lower 80MHz channels of the 160MHz channel (i.e. channel 36 - 48 for 5250MHz, channel 100-112 for 5570MHz) and wait for DFS (1min). Once it's up, logread should show wlan1: AP-ENABLED. -- Strangely, if I use higher 80MHz channels, the radio can be enabled, but no device can connect.

Does that mean actual 4.8Gbps AX speed if 4x4 is used? :star_struck: I don't have a device to test.

Hello is anybody having any problem booting on the latest snapshot via auc?
Updating via auc hasn't resulting is a successful reboot in the last 36hours.
Thankyou Daniel for the recovery instructions Or wouldn't be able to post this

64

I ordinary wouldn't want to update my router so often but as WiFi 6 seems to be a working progress and progressing quite fast recently. I just can't help myself.
Longing for the days of a long term release with ax support... As a side note anybody know where to make a request for the included packages in the releases. As native ipv6 and tunneling ip4 is becoming increasingly common in japan

65

What is auc ?? I have download a last snapshot no problèm for me

@daniel I recently sourced some proper JST PH 6 pin serial cables and as I also have earlier Linksys devices like a WRT3200ACM and a WRT32X I noticed that while the pinout is really the exact same (and my cables indeed work on all of them) you used a different notation for the E8450 (e.g. likely RX/TX from the PC rather than the target point of view). One can easily see what I am talking about looking at the following pages:

(Those all have the same picture.)

Do you agree to streamline this? Should I do the edit or you still have the source of that image?

Same here. I end up went to failsafe, manual bring up Internet, wget and sysupgrade. failsafe was also half broken: mount_root, firstboot, sftp-server don't work.

Yes, please go ahead, always glad to see things converge :slight_smile:

I had the same issue. It's due to the recent kernel update but it's working now.

I'm trying to figure out how we can get the (current) TIB file from auc because I'd love to have this 'working' version in my backups (just in case).

I like that idea, now I know its working again i just used the easy oem install script but added the extra package that i need, now that i now the current snapshot is bootable.

Nice! Keep me posted if you find anything. I used the Luci-AUC and it worked and have been using auc via CLI again.

We can probably generate our sysupgrade.tib package if you know what packages we need via: https://chef.libremesh.org/

73

@daniel , can you tell us what packages were included in your build? I really like the way it's put together. Thanks again!

guys, can you help me, please

  1. it is brand new Belkin RT3200
  2. I'm uploading openwrt-mediatek-mt7622-linksys_e8450-squashfs-sysupgrade.biin in the vendor firmware Web UI upgrade page
  3. after that 192.168.1.1 is ERR_CONNECTION_REFUSED
  4. DHCP is working
  5. I'm trying to reset it, push reset button and swith on the router, but the colour of indicater still white, it reboots, and that's all
76

use recovery install and after sysupgrade.bin like this thread

77

Do you get that when trying to open 192.168.1.1 in browser? If so, and if you are installing a snapshot image (afaik there are no releases for this router yet), it likely doesn't have the LuCi (web interface) installed. You can install it by connecting via ssh and issuing opkg update && opkg install luci

78

Im trying to set up two of those for mesh and it seems i cant get 160mhz working (config made with uci). Any advice? I already tested a bunch of channels like 36, 52 and 100. I always land on vht80 or he40. What is the exact version of your firmware?

Edit: can you please show me your wireless config with working vht/he160?

79

I'm using snapshot r16750-f716c30241
I never used mesh (on openwrt) personally. I'll would try one as AP and one as station first.
What's your iw wlan1 info?

Hi all,

I am looking to install OpenWRT on the Belkin router. Following the advice to backup all mtdblocks, I flashed the "recovery" (not recovery-installer) image. I was able to backup mtdblock 0-3 which I have saved. I did not find any volume called boot_backup, however, so I'm assuming that's performed by the recovery-installer image.

So, from this state, how do I continue to install OpenWRT. It's not clear to me if I'm able to flash the recovery-installer at this point?

If it can't be done from this state, what should I do to get to a state where I have more options? Flash an image (which one?) from luci or is it better to utilize TFTP recovery and flash something through that? If so, to which image, or can/should I flash vendor/stock firmware from there and begin anew?

The goal is to get OpenWRT with UBI properly installed on the router. This includes whatever install is performed by the "recovery-installer", but if I read correctly the best way to have taken backup was to first boot into "recovery".

Thanks for any help you can provide.

oh god, thank you!

probably we need to write in FAQ, that you need to install LuCi. And other question, why Reset button is not working.
