What could be the most likely cause of occasional wifi signal loss?

I'm currently on TP-Link WR1043ND with 1.3.9.
Running fine for about 4 days, but today, it totally lost wifi connectivity, WLAN light was off - had to reboot the router to recover.

A couple of hours thereafter, the WLAN light went off again - but it did recover itself after waiting for about half a minute or so.

Sounds like flaky hardware? Or could it be attributed to the firmware?
Or maybe heat? My router is placed atop a DVR which can get quite warm to touch.

Heat issue is easy to troubleshoot - just set it somewhere cooler.

If it still repeats, then its probably not heat.

However, the newer routers, if running under heavy load, do get
quite warm and the faster processor and ram doesn't help with heat.

You could also monitor memory usage - see if its maxing out RAM
for some reason - do you have alot of stuff enabled?

Like QoS, bandwidth monitoring, rules, etc?

Thanks for the tips, will monitor.

Memory utilization hovers around 93% (26.8MB / 28.8MB).
Default settings except for WPA2/PSK and one regex URL access restriction.

Btw, I noticed that with each wifi packet, the WLAN light goes on then off, then on, then off - instead of actually blinking (whereby light goes off and then back on almost immediately), i.e. it can sometimes show an off state when there is no wifi traffic to constantly toggle it on and off.

Is this behavior adjustable in future firmware upgrades?
