OpenWrt installation on Linksys EA9500

Installing and Using OpenWrt
1

Good morning folks.

My trusty EA8500 shit-the-bed after several years of work. I had a decommissioned EA9500 at work which I bought home and I am attempting to get working. I downloaded the firmware from the ea9500_v1 toh page and flashed it via tftp. Router boots successfully and I get to a login prompt, I see via ifconfig that br-lan is assigned 192.168.1.1, but connecting the router to the network I cannot talk to it on any of the lan ports and the wan port does not appear to attempt to lease an ip address.

Is the 21.02.2 version showed on the toh page actually a stable version, or is this still a work in progress?

I probably screwed up on what I was supposed to flash. The toh page, under the "OEM installation using serial+tftp method" is unclear which firmware file is supposed to be flashed, whereas the non-US instructions are pretty clear and say "flash this first then flash this". Since the "Firmware OpenWRT Install URL" was an img and not trx file, I flashed the firmware trx under the "Upgrade URL".

Feedback/guidance from those "in the know" would be appreciated. thank you, vinny

The problem appears to be with 21.02.2. I re-flashed 21.02.1 and am able to communicate with the gui interface. After doing some setup, I attempted to re-flash 21.02.2 through the GUI, and the EA9500 became unresponsive again, so I went back to 21.02.1.

Is anyone actively using OpenWRT on this router, or is this build simply an experimental version? Even with 21.02.1 there appear to be several features I had on my dead EA8500 which are very buggy on the EA9500.

When booting he EA9500 on 21.02.2, I see these messages in the startup:

[    4.148865] kmodloader: done loading kernel modules from /etc/modules-boot.d/*

whereas I do not get the "failed to connect" messages using 21.02.1.

Continue to have problems with 21.02.1 on the EA9500.

For example, the 5Ghz channels one can select in the stock OEM firmware are 36, 40, 44, and 48 for Radio 0 and 149, 153, 157 and 161 for Radio 2.

However, if I attempt to use any channel above 112, I will see messages like this on the console:

[  171.434382] ieee80211 phy2: brcmf_cfg80211_start_ap: Set Channel failed: chspec=55414, -52

[  175.337897] ieee80211 phy2: brcmf_cfg80211_scan: scan error (-52)

I have not tested every channel, but trial and error seems to indicate Radio0 and Radio2 can go to channel 112 (anything above that will yield errors akin to those above) but no higher.

#  cat /etc/rc.local
# Put your custom commands here that should be executed once

iw dev wlan0 set power_save off
iw dev wlan1 set power_save off
iw dev wlan2 set power_save off

exit 0

Allegedly that should help. We will see...

6

This is crap non of them bulids works on 9500 just shoutdown the…can not even boot tl-wdr3600 , don’t publish firmware that brick your stuff

7

No difference w/ the iw dev wlan commands. Same symptoms.

Additional messages I see in the boot log:

no idea what you are talking about. OpenWRT boots but appears to not properly talk to the hardware for some reason. I haven't bricked my router yet.

This is a new issue that suddenly started after several years. Since I put the power_save changes in place, I have not run into any further issues. Uptime is approaching 5 days.

Okay, are you using the public builds downloadable from downloads.openwrt.org ? if so, which release are you running?

I tried 21.02.2 and when it boots I get the "Failed to connect to the switch." error on boot and cannot connect to the router at all (via 192.168.1.1 or via wifi). Downgrading to 02.1 I am able to connect but even with the power save parameters the 2nd radio refuses to into the higher channels.

Not sure where to go now.

10

In most geographic locations, channels 50 to 144 are reserved for radar (DFS) and should be avoided.

Pick a channel between 36 and 48 or 149 to 161...depending on channel usage in your area.

12

See the hardware data for this device...

WLAN Comments:
radio0 just supports channel 36 up to 48 + radio2 only 100 up to 140

It is well-known that Broadcom chipsets have limited OpenWrt support.

13

21.02.1 I get the same errors (set channel failed and scan errors) if I attempt to use 149 through 161. Anything above 112 gives me the error. I have the US country code set.

21.02.2 will boot but I cannot connect to the web interface (192.168.1.1) nor can I ping outbound from the box. The switch appears inoperable. I see an error during boot telling me "Failed to connect to the switch." in pre-init. I do not know how to correct this error.

The stock linksys firmware works fine on all 5Ghz channels
