Dear Sir/Madam,
I had already reported such bug in the previous firmware, v3.3.3.1, on 27th June, 2010 in this forum.
Reference: viewtopic.php?f=2&t=3418
However, this bug is still existed in the latest firmware, v3.3.6.1. I am quite disappointed that DrayTek used for a long time to fix it, but this bug is still existed yet.
In the control panel, [Bandwidth Management] -> [Quality of Service] -> [Service Type] -> [Edit], I still cannot add the user defined service types which is greater than 10. According to the current user manual downloaded from DrayTek website, it stated that the user defined services types is supported up to 40.
Quote from Page 197 of UG-Vigor2920-V2.0.pdf: "By the way, you can set up to 40 service types. If you want to edit/delete an existed service type, please select the radio button of that one and click Edit/Edit for modification."
Honestly, I had reported such bug in your forum and the DrayTek official support previously. But they did not show me any solution or schedule to solve such bug.
I look forward to hearing your response.
Your faithfully,
Jacky Luk
