Take the tour ×  I have a home wifi access point consisting of a
small Intel board with Atom CPU, 4 GB of memory and a PCI wifi
card. Everything works fine, only that I experience major lags
during playing of computer games online. I am not entirely sure
that it is the router's fault, but it seems to vanish after a
reboot of the AP. During such lags, for up to 3 seconds, no
packages are received by the game, while other services (like
Teamspeak) keep working. It seems to be a single UDP (?)
connection that hangs for some seconds. Also when I bypass the
router and use the ethernet of my internet modem, the lags
vanish as well.  Now, how could I find the root of the problem?
The high traffic of the game seems to trouble the router so that
it hangs sometimes and I don't know how to create artificial
traffic conditions similar to the ones during gameplay.  On the
AP, hostapd is used for the Wifi and the traffic is routed
between the ethernet port and the Wifi clients. I basically
followed this tutorial and set up
