Re: Better wifi performance with FRITZ!Box 3490?


[re: ajays] [link to this post]
 
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.

Agreed, browsing, downloading and uploading will be fine.

Like I said, its a shame you cannot add the host address doing the pings and the amount of allowed Pings to allow on the FritzBox, that would resolve this issue.

What it needs is an ISP that uses these boxes to push AVM for an update

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!!

I presume more than one app was trying to ping your router - TBB BQM plus another. Then the second app stopped pinging the router after a period of time.

OK - so what, if anything, do I do about it?

What do you mean by multiple pings?

This is a Fritz!Box 3490 on an absolutely dreadful connection which syncs well below what it should do (below handback threshhold), both downstream and up; https://www.thinkbroadband.com/broadband/monitoring/...

I'm not seeing anything like your graph is showing.

On mine, the only app was tbb - unless you are doing pings yourselves

I have not long asked via twitter for a feature request to allow the user to be able to add a host address to the allowed to ping list and also allow to fine tune the amount of ICMP Pings that host is allowed to send every X time.

They normally reply to me not long after the tweet, but it being the weekend I might not hear anything back till next week.

If I don't hear anything I will send them a direct message or email.

I really loved the 4040 router, it might be ugly but it worked ok for me, well apart from the dropping of packets LOL.

How's this for instant gratification - I phoned one of your colleagues in the Zen sales department after I'd read your reply, and received the Fritzbox around lunchtime today. Have just connected it all up and the wired speed is a little faster. But... wait for it... the wireless speed is nearly three times as fast as with the old router. In fact, wired and wireless speeds are indistinguishable. Amazing.
