Busy setting up a Hotspot Splash, sharing a limited ADSL with Campground users for free, so fairly distributing bandwidth, especially upload is important.

However, I find that the upload is not at all adhering to the location defaults. I have set 128/64 (as ultralow experiment), but a speedtest is showing 0.11Mb/0.79Mb. When setting 256/128, the speedtest shows 0.23Mb/0.79Mb. So upload is always roughly the max of my entire ADSL.

It seems download is adhering to limits, upload is not. And I am far more worried about upload, seeing how we have only 1Mb of it and I am predicting a lot of skype-video usage. I am checking with my ISP to see if they cannot change to Annex-M, but SDSL or VDSL is not an option here in the rural area's, so it would be nice if the upload could be limited as per location defaults.

Device: DD-WRT V24 preSP2 build 15778
TP-Link WR941ND 400Mhz atheros 32MB, CPU not heavily impacted during this test.

I also activated the device's overall QoS, setting a total device limit of 6146/768, and rebooted, and suddenly the per-session limits are followed for both up- and downlink. 256/128 nicely gives 260/112.

Not sure if it was the reboot that did it, or maybe the general activation of QoS service (maybe that service needs to be active for this?) but I am happy, and think I shall stop tinkering with it now.

Edit: Some further info: Setting a total upload QoS limit in DD-WRT seems to choke the router somehow. If I have any value in the upload, I can never get a total bandwidth higher than 400, but if I leave zero (no upload limit) in DD-WRT it goes to 800, but then the per-session limit is not enforced again.

Rather disappointing. Maybe its all firmware related, maybe its more generic.
If possible, please post below if you find you have a DD-WRT (with another build) where per-session limit is followed, but setting the QoS does not kill the total upload.

Thanks

Hello,

As you have stated, when using DD-WRT firmware the upload limit works only if you enable QOS.
