Net usage causes arch based router soft freeze/hang (kind of)

My headless router hangs at some random intervals, mostly (as I've noticed) when I'm trying to upload larger files.
After some (random amount of) time the router becomes irresponsive, none of my LAN machines can reach the internet, not even ping the router.
The only thing that helps is to make any kind of physical access to the router, such as plugging in a keyboard, a USB device, or anything like that. After this action the machine is like "waking up", and continues to route the traffic as expected.

The sad thing is, I don't see anyithing in the journal. I'm not kidding, according to the journal nothing happened, a few times it just says "modem hangup" (I'm on adsl with rp-pppoe) , but the timestamp corresponds to the moment when I've plugged in a pendrive, for example (that means the moment of the wake-up).

Do you have any ideas what can cause such kind of behaviour? I've never seen something like this before.

the box has the following hardware:
VIA esther 800mhz Processor
512 MB of RAM (memtest shows no errors)
8GB CF Card
3 Realtek 8139 10/100 Mbps NICs
