I recently bought an #Atari ST Book, and I'm in a journey or repairing it. You can check it here: https://www.exxosforum.co.uk/forum/viewtopic.php?f=29&t=7118

Found the problem! #Atari #STBook

Just finished building PAL-1, a replica of the first computer using a 6502 processor, KIM-1 (designed by Chuck Peddle of MOS Technologies).
It is super interesting, because you can program it in machine language on the included keyboard.

Gerber files uploaded! 🙂

The PCB I designed for the #Atari 8-Bit Ethernet Project card using an #Olimex board works!
I only forgot to connect 2 ground pins. 😁
Soon I will upload the fixed gerber files to https://github.com/AndresPlazaR2/atari_8bit_ethernet

My #Atari 8-bit network card is almost working!

Thanks for all the suggestions!
Problem fixed after rebooting the AP... But I hate that I don't know the real reason, and I just hope it is a one-off.
(I know, I should have rebooted the APs yesterday, but because the other devices were working, I did not think that could help)

@gerg Thanks for the suggestions! I did check on kernel messages and other chains; nothing.

But this morning I rebooted the APs and that fixed the issue. Because other devices were working I did not do it earlier.

@danielscher Thanks again!
Rebooting the APs fixed the issue. I should have done it yesterday, but the fact that other devices were working obfuscated my judgement. 🙂

@danielscher Thanks!
Well, I rebooted, disconnected and disabled/enabled DHCP several times, so I imagine that would do it?
I checked the routing table while doing the steps above, and it always cleared. ☹️

@friendslive Not yet; will try that next. Thanks!

I have the weirdest problem with my laptop, and I have no idea how to even debug it. So, I'm posting it here in case anyone has an idea:

I'm using Ubuntu 22.04; all updates installed.
Almost all the time, I'm connected to my home wireless network (router + APs).

Last week, the connection to the wireless was working fine. I went on vacation for one week; I took the laptop with me so it was not connected to my home network. Today I tried to connect to my WiFi, but it is not working.

The laptop can connect to the wireless network,
and it gets the IP, DNS and routes assigned via DHCP. But pinging to the router does not get any response.

I tried the wired connection (same router), and it works.
I tried the WiFi hotspot from my phone, and it works.
All other devices connected to the wireless network work.
There are no firewall rules in the AP or router blocking my laptop (again, it connects to the wireless network and DHCP works).
iptables is clean.

If it is a problem between the laptop and the AP, how can it get all the DHCP info?

If the problem is between the AP and the router, how do the other devices work fine?

If the problem is the wireless driver in Ubuntu, how does connection to the hotspot in the phone work?

I removed and recreated the WiFi configuration to my home network; it does not fix it. I also tested using a static IP.

I have no idea what this could be.
Any ideas?

Reposts appreciated. :-)
