Hi all,
I have successfully flashed OpenWRT onto a AVM FritzRepeater 1750E a while ago. It works fine as an access point, i.e. no firewall/DHCP/DNS/… needed on the machine.
While it works when using it “as a client”, I have trouble when logging in via SSH or when trying to upgrade it.
When ssh’ing into the machine using the dropbear SSH server, I can change directories normally. But there seem to be some “triggers”, like copying over a file via scp/rsync, that freeze the device. Even if it is just a SHA256SUM file.
The SSH connection is not dropped, but does no longer react to any input. It might take a minute or two for the text input (or even just hitting ENTER) to appear.
The device is pingable during this, even though the ping times seem to go up higher (like 1ms to 70ms) .
Sometimes it seems to recover from this, sometimes it seems to “do something” and files in /tmp vanish afterwards. Not sure if it does a reboot, right now I cannot login and check the uptime.
You can imaging that copying over firmware files is not fun on this device. So upgrading is currently not possible.
Normally the Luci UI is reachable and works (slowly, but it works). Sometimes it freezes and I get “bad gateway” errors or just pages loading forever. Sometimes it recovers.
Any ideas how to fix the device (without throwing it away and getting a new one, I mean)?
I think I might just remove Luci from my custom image and see, if this helps.
Thanks in advance!
Kind Regards,
Johannes
