Re: Better wifi performance with FRITZ!Box 3490?

In reply to a post by ajays:
As a way of mitigating the damage of a ICMP Flood DDOS attack the FRITZ!Box deliberately drops ICMP echo requests if it receives more than one ping per second.

On the TBB BQM this will look like continuous packet loss. But, only ICMP packets are affected.


When I had similar issues with my 7490 earlier this year, neither Zen nor AVM could offer an explanation. The packet loss disappeared after a couple of months round about the time that Zen switched my connection to their GEA backhaul. I would be interested to know if there is an explanation for what is happening here:

High Bursts of Latency

Fritz!boxes do not like BQM!!


This problem has now been fixed with AVM's release of its latest beta firmware. Previously, AVM said that there wasn't an issue after looking at the boxes diagnostic. They pulled the beta shortly after I raised the issue with them.

I should add that the Fritz!Box mesh (box plus 1750E WLAN) gives excellent wifi speeds all around the house.
