I am seeing very interesting behavior on one of my networks. I am running SmallWall in front of a Netgear ProSafe switch and a couple of APs. One AP is Ubiquity and the other is Cisco running DDWRT.
The behavior is that 4-5 users who are running different Linux distros all have trouble with web browsing. They can navigate to a web page but after interacting with the page for 60-90 seconds the page becomes unresponsive and eventually hangs. Both Firefox and Chrome respond identically. There are dozens of Windows users on that network and they never have an issue. I have also noticed that sometimes Signal messages will not send on Android phones when connected to the network. When disconnected they send immediately.
If the Linux users connect to a wireless hot-spot on my phone (for testing purposes only!) they are able to surf the web without incident. The only common theme is Smallwall. I have connected both APs directly to my SmallWall appliance and eliminated the switch - same behaviour. I would love to hear thoughts on debugging this. I have run a number of Wireshark and Fiddler traces without seeing anything obvious.
All the best!

The Soekris is a bit under powered for modern internet speeds. That may be the cause of your problem. To get gigabit speeds, you actually need 3rd of 4th gen core I architecture. (Not CPU, but chipset) So, yes, I would try better hardware first just to be sure.
I agree it is under powered. The CPU and Memory values show it is not breathing hard though. I would expect Windows and Linux to suffer the same fate if it was purely hardware (I admit non-Intel NICs may give me pause on the hardware side).
I'll try my MITXPC box and I may also try one of my super-duper boxes running OPNSense for grins if that doesn't work. This has had me baffled for a while now and I am just now getting round to enough spare time to dig in deeper.
