No those two configs are not compatible, you need to set up from scratch for such a large version jump.
To fix the browser I would normally suggest a “hard refresh” e.g. Ctrl+F5. This is the less nuclear option compared to a full browser cache clear, but you might need to do it on several pages (in particular the Connection Basic page).

Attempt to connect to the upstream router, wait 60 seconds and then run a “logread” command on the router to see if anything indicates why it is not connecting.
Just to remind you how to configure the bridge, the Bridge IP must be outside the upstream routers subnet. So if upstream is 192.168.1.x (example) you might choose 192.168.2.1.
On successful connection, the router is now accessible at the IP that the upstream router assigns, in the 192.168.1.x subnet, e.g. 192.168.1.100. The device you are using to configure it will also acquire an IP in this range, but may require you to bounce the connection (unplug/plug Ethernet) to trigger a DHCP renew.
IF connection is not successful, you can set your IP on your device manually to 192.168.2.10 (inside the bridge IP subnet) and then navigate to 192.168.2.1 and attempt to recover the device (and/or read the logs).

The Gargoyle router did not fully recover after the reboot last night. After a power cycle, it came up running normally this time.

I do have the router on its own subnet. The primary router is in a different building, I am unable to reach it without getting outside and physically closer to it, which won't happen at 3 AM.

I did set up 1.15 from scratch, just curious if the 1.12 config would have worked.

I'll need to see what logs are available. are they cleared when power cycled? I looked around, but was unable to find logs. Where are they located? I don't see a logs field in status page.

I did go ahead and install a logread plugin, but saw nothing prior to the power cycle this morning.

Thanks

Yes logs are in a circular ram buffer that is cleared on restart, so you will need to get them before rebooting.
The logread plugin will work just fine, otherwise the “logread” command on the terminal

I also used the terminal and saw the same results. The part of this that could be sketchy, is having the ability to access the logs after the router craps out. I can try to get to it, but it may require a power cycle, which would then wipe the log.

I am debating now if I should try to flash 1.15, or wait another day and try to extract a log file.

Just a few minutes ago, the router was dropping the connection to the main router. After it reconnected, the throughput was extremely slow, like less than 4mbps, when it should be between 150-200 mbps. I copied the logs as a text file and rebooted. It is now back to speed. How would you like me to send you what I have?

Thanks,

SL

You can paste the contents into pastebin and link it. If you’re worried about sensitive info you can send it via PM, otherwise just post the link here.

Today, the router came back running correctly after last night's reboot. But, as I said it flakes out randomly also now.

Nothing particularly stands out in the logs. Each disconnection is quite non-descript:

Code: Select all

wlan0: Connection to AP 8c:3b:ad:29:54:07 lost
It is not indicating that the upstream AP forced a disconnection, it looks more like a loss of signal type event to me.

Is the signal level at the router OK? Is the country code set appropriately to gain the maximum allowable transmit power?

First disconnection was 9 hours, next one was 3 hours, so it doesn't really point to a cyclic thing occurring either.

The RSSI from the main router is -55 dBm (5 GHz). The country is unown to me. TX power is set for max, @20 dBm. I recalled seeing a country setting, that was world, but that may have been version 1.15. I can't find it now.

What I found to be the more alarming issue, was that the throughput was crap, until I rebooted, then all was good.

The bridge is a point to point link, using an outdoor MIMO panel antenna.

How far is the link?
It doesn’t matter if the panel antenna is shouting at the router if it doesn’t have a big enough signal to shout back.
20dBm is limited, you might get another 3-6dBm by setting your country. Yes in 1.15 this is exposed on the GUI, on earlier versions it would be a manual setting.
