Hello world!

I use Telecom HG630b router, and I am having some problems filling out information for the QoS (Quality of Service) section. I have recently decided to use this feature, as my brother streams a lot of anime in my household, and I play a lot of online games. I am experiencing game changing lag (200-2000ms) when I am used to playing with a ping of around 100ms.

My solution of choice is to use the QoS feature to split the bandwidth priority evenly among our computers, and I understand that my router can indeed do this. The idea, (for those of you who don't know) is to essentially "throttle" the bandwidth when it reaches certain limits. The end result should be that my brother can still stream his movies (albeit with some delay) and I can still play games with minimal lag.

So I have found the section in the "Telecom HG630b Home Gateway" under advanced called QoS. I have done a lot of research regarding how this feature works, and I am certain that with the right specifications, I can allow myself (or deny my brother) enough bandwidth.

The problem is with what exactly I need to enter into these forms:

First Page



I have seen youtube videos demonstrating how to edit this information for different routers, and as such I am unable to use that information to help me. I have read user manuals for this exact router that do not have any specific advice for how to fill out these forms, only that they exist.

Please help me world. I am too afraid to simply trial-and-error this thing, as my research has taught me that "you can turn your modem into a brick" if you stuff it up. I have no real knowledge of these specific fields I need to fill out as the help documentation is less than helpful. I will paste it below for your amusement:

"DSCP: used to specify the DSCP to be classified."

That is not helpful at all:


QoS When bandwidth is limited through the QoS function, the gateway can allocate all the bandwidth to a certain application, increasing the priority of the application. Global Settings On this page you can set certain global parameters of the QoS. described as follows:


  • Enable: is used to specify whether to enable the QoS function.
  • Bandwidth: is used to specify the bandwidth used for the QoS.
  • Queue type:is used to select a policy used for the QoS.
    The available types are described as follows:
    • PQ: if you set Queue type to PQ, four queues are listed based on the priorities. The priority is classified into the highest priority, high priority, medium priority, and low priority. The gateway first schedules the queue with a higher priority. If the queue with a higher priority has a packet cache, the queue with a lower priority cannot be scheduled.
    • WFQ: If you set Queue type to WFQ, four queues are listed. You can set the weight of the bandwidth occupied by each queue. The bandwidth is allocated to each queue based on the corresponding weight.
    • WFQ,PQ: If you set Queue type to WFQ,PQ, four queues are listed. The first queue has the highest priority, the other queues scheduled by WFQ.

Note: the templates have certain preset classification rules. After you select a template, you can modify the parameter settings of the template.


  • Queue: the parameters of the queue vary with queue types. You need to set the queue type in the global settings, and then set the corresponding queue parameters. For each queue type, all the queues can be enabled or disabled separately.
  • Policy: You can limit the rate of stream though configuring the Policy parameters.
Traffic Classification On this page, you can manage the traffic classification rules on the basis of the QoS settings.
The parameters are described as follows:


  • Rule name: It is used to specify the name of the current rule.
  • Enable: used to specify whether to enable the current rule.
  • Source MAC: used to specify the source MAC addresses to be classified.
  • Dest MAC: used to specify the destination MAC addresses to be classified.
  • Source IP and Source IP Mask: used to specify the source IP addresses and mask to be classified.
  • Dest IP and Dest IP Mask: used to specify the destination IP addresses and mask to be classified.
  • Source Port and Source Port Max: used to specify the range of the source ports to be classified.
  • Dest Port and Dest Port Max: used to specify the range of the destination ports to be classified.
  • LAN Interface: used to select the lan interface on which the packets are classified.
  • WAN Interface: used to select the wan interface on which the packets are classified.
  • DSCP: used to specify the DSCP to be classified.
  • Protocol: used to select the protocol used by the packets to be classified.
  • VLAN ID: used to specify the VLAN ID to be classified.
  • 802.1p: used to specify the 802.1p values to be classified.

Note: After setting the preceding matching conditions, you can perform the following operations on the matched streams:


  • DSCP mark: used to add a DSCP mark to the matched stream.
  • 802.1p mark: used to add a 802.1p mark to the matched stream.
  • Policy: used to select a Policy that the configured rule is to be applied. For details about how to configure the Policy, see the description about the QoS page.
  • Queue: used to select a queue that the configured rule is to be applied. For details about how to configure the queue, see the description about the QoS page.
Note: After setting the parameters, click Submit so that the rule can take effect. In addition, you can modify, delete, or disable the rules.


I know how to find my mac address and ip address using ipconfig in cmd.exe. I simply do not know the difference between source and destination. Port min and max. Or any of the several other fields.

Thank you to anyone who can help me.

Note this is probably going to be for *outbound* bandwidth, not inbound.  I would use WFQ.  Normally with QoS the "bandwidth" you specify states the "minimum" bandwidth to allocate to that class, not the maximum.  Although many devices can also do policing and shaping.

So in this case, you can allocate the traffic you want to "protect", aka your traffic, to a queue and give it some bandwidth.  Then if you want to use some outbound bandwidth the router should throttle back the other traffic to give you your guaranteed minimum.

Oh no!!!

Please tell me I am wrong. I seem to have made a fool of myself :/

I guess it would pay for me to have researched a little more into WHAT QoS is as opposed to HOW to implement it. If it is the case, that I can only control outbound traffic with this feature, then surely it is not the feature I should e focusing on. That being said, it wouldn't hurt to have more control over outbound traffic.

I now pose the new question: Is there a way to control inbound QoS?

Will I have to pay for some program? Does such a program exist? Is there any other way to control inbound traffic? Has ANY router the capability? Do I have to move out? Change my hobbies?

So many questions, but thanks for the reply, yo. This is the advantage of forums. I now have a lot more to think about. It never crossed my mind that peoplewould even NEED to control outbound traffic. Cheers.

Help me world.

I haven't used the specific router model you mention, so its capabilities may be different, but I have done a lot of QoS work on Cisco kit.

Typically QoS does not "kick in" until you have congestion - aka a queue of packets waiting to go out of an interface.  QoS then re-orders those packets in the queue to maintain the policy.  Queues mostly form for outbound traffic.

If you are most worried about traffic into your site what you really need is traffic shaping or policing, where you limit the flow of data heading out the LAN (that originated from the WAN) to a specific value.  Either that or you use hierarchical QoS, but that is probably a step too far for you if you are just starting to get to grips with QoS.

A cheap option, if your inbound bandwidth is more than 10Mb/s and the machine you want to limit is Ethernet connected, then change its interface speed to 10Mb/s.  Quick, cheap and easy.  Then they'll have trouble getting more bandwidth than that, and you can use everything else that is left over.
