I was describing my observations, nothing more, nothing less. Never expected wonders. Full stop. Simon Slater schrieb: It prioritises, but does not guarantee speed throughput. the slowness you get is more likely that the data has to be inspected to identify each packets Access Category and then prioritise each packet to send it on. There is no deep packet inspection. So the slowness cannot be explained with that. The classification is done by the application. The router simply reads the classification and puts the data into the corresponding queue (in case of downstream). Should not consume that much CPU time (and it does not as stated above). If there is no or only little load on the medium by other clients, I expect maximum possible speed.

Just enabled WMM again and everything gets incredible slow. Doesn't matter what and where I download from (vimeo, LAN server, speedtest, ...) and which wireless client I use (Windows Laptop with 11g, Macbook with 11n network card). In a former posting I said that only WAN<->Wireles is affected, which I cannot hold true anymore. ... View more

Hi Thomas, I still have the concern that WMM is somehow broken. First: the IP packets are classified by their Differentiated Services Code Point (DSCP) value (0x00 - 0x3F, 6bit). In general there are only a few classes (you named it) to simplify things: Best Effort (AC_BE) Background (AC_BK) Video (AC_VI) Voice (AC_VO) The classification takes place inside wireless client (the application or the operating system has to set the DSCP value) or inside the router ("CoS to DSCP" in conjunction with QoS). Second: Depending on the DSCP value and wireless load, wireless packets are delayed by the receiver (e.g. the router in case of uplink traffic) by either not sending or delaying ACKs. The result is that other stations in the network get a higher probability to access the medium.  But dropping ACKs will and delaying ACKs can result in a complete loss of the transmitted data. This is bad because already transmitted data needs to be sent again. TL;DR So, again my question: Why should enabling WMM slow down my wireless downlink speed if no other is accessing the same medium? The settings on my laptop are the same, only the router config has changed. ... View more

Thomas, do you have DynDNS running? Just guessing... The last thing I did: I disabled DynDNS. So far the router is running fine. False Alarm, just had a few disconnects on my laptop. After that I wasn't able to connect my server. Wireless-to-Wireless is still working. So, still weird behaviour observed. All router settings are basically set to default values. In the last 3 days I collected nearly 40,000 (sic!) syslog messages from the router. I need more time to filter them. ... View more

...this seems to be a general problem. Enabling WMM leads to a decreased download speeds under certain conditions. So I keep it disabled.
