How do I interpret my BQM graph

Interpreting your BQM graph is a combination of comparing a current graph to your history, and if you are seeing unusual patterns asking other users on the same ISP or from the same part of the country if they see similar patterns. We have collated a few commonly seen examples, and annotated them with our interpretation of what the connection is doing. All these graphs are taken from the same date/time.

Packet-loss from bad sync or heavy downloading

BQM graph showing consistent packetloss usually from bad sync or heavy constant downloading

This graph is showing consistent packet loss between 2% and 15%, which would making gaming or Voice over IP (VoIP) across the connection very difficult. The minimum latency is higher than average, which suggests a permanently congested link somewhere between the broadband router and our BQM Pingbox. The fact the blue area is still narrow suggests the packet loss is not due to the user downloading on the connection, but some issue in a core network. The toothcomb effect, is most likely an artefact from the broadband router in use on the line.

Peak time congestion

BQM graph showing peak time congestion packet loss

A classic example of peak time affecting latency, and suggests the provider in question is running its links at very close to capacity. The peak time starts at 4pm and continues until midnight. On this graph it looks as if the connection was used to download/upload something around 1am and 9am, with some more intermittent usage as the morning progressed.

Re-sync

BQM graph showing a minimum latency change due to resync

This graph shows some usage in several blocks between 2pm and 10pm, but the point of interest is at 7am when the minimum latency jumps from 22ms to 40ms. There is a very narrow red spike at this time, which suggests a short resync by the router, this may have been due to noise, or a provider forcing interleaving onto a line to reduce the number of errors (though there is no evidence that this is needed on the line). The most likely explanation is the resync has jumped the user onto a different gateway at the ISP, which has a higher baseline latency. To ascertain what actually happened, more graphs from the same provider would need to be compared.

Very busy broadband connection during night-time

BQM graph showing a very busy broadband connection

We are looking here at what is most likely a very busy broadband connection, perhaps with a combination of fast downloads and uploads happening at the same time. Saturating the upstream of a broadband connection will have a significant effect on latency. When a connection is very busy, it is not uncommon to see some packet loss, as the router will be very busy handling all the data transfers, and thus may ignore the ICMP (ping) requests occasionally.

Peak time congestion during late evening

BQM graph showing peak time congestion raising minimum latency

This graph covers a different time period to the other graphs, but shows what effect a heavily congested link from an exchange to the wider internet can have. In this case the minimum latency climbs from a high but OK 40ms to over 140ms at the busiest point in the evening. The consistency of the latency, i.e. wide green area with a narrow blue area helps to suggest this is not congestion from a single users line, but the effect of a much larger link becoming saturated. Anyone who is a gamer would not be able to play first-person shooters with latency like this at peak times.

What should I see if my connection is idle and running well

The graph below is a great example of what a nice stable broadband connection should display:

BQM graph showing a good connection

The green area is stable across the 24 hour period, which means that the line is performing well. There is almost no blue on the graph, which tells us that in each 100 second period the latency stayed very close to the minimum which is around 16ms for this connection. The yellow (which is maximum latency) only spiked twice, at around 6:30pm and 10pm, which may represent someone opening a webpage or two at these times.

The red area of the graph, which runs along the top edge normally shows no packet loss most of the time, but there was a few packets lost at just after 7:15pm.

The BQM will usually show a red line that is one or two pixels wide stretching from the top to the bottom of the graph if a router is re-syncing.

Функциональные возможности

так, точка доступа ZyXEL G-560 EE, ориентированная на домашнее использование, имеет компактный корпус с габаритами 112Ѕ106Ѕ23 мм и массой 0,2 кг. Конструкция корпуса допускает как настольное расположение, так и настенное крепление. На тыльной стороне устройства расположены порт Fast Ethernet для подключения к локальной сети, разъем для подключения внешнего источника питания и интегрированная поворотная антенна с коэффициентом усиления антенны 2 dBi. При этом отметим, что выходная мощность передатчика составляет 18 dBm, а чувствительность приемника равна –82 dBm.

Основным отличием точки доступа ZyXEL G-560 EE является поддержка расширенных протоколов беспроводной связи 802.11b+ и 802.11g+. Напомним, что протокол 802.11b+ предусматривает максимальную скорость передачи до 22 Мбит/с, а протокол 802.11g+  до 125 Мбит/с. Естественно, что воспользоваться преимуществами расширенных стандартов можно только в том случае, если все беспроводные клиенты сети также поддерживают расширенные стандарты.

ZyXEL G-560 EE

Настройка точки доступа происходит очень просто. Достаточно с использованием Web-браузера ввести IP-адрес устройства (по умолчанию он равен 192.168.1.2 и написан на тыльной стороне устройства). В главном окне программы можно выбрать русский язык утилиты конфигурации и ввести пароль (по умолчанию пароль равен 1234 и тоже написан на тыльной стороне устройства). После этого предлагается ввести новый пароль для доступа к устройству, ну а если вновь введенный пароль вы случайно забыли, то имеется кнопка Reset, которая позволяет сбросить все настройки к настройкам по умолчанию.

Утилита управления позволяет ознакомиться с текущей настройкой точки доступа, а именно: MAC-адресом, версией прошивки, IP-адресом и маской подсети, а также с IP-адресом шлюза. Кроме того, имеется возможность просмотреть заданный SSID беспроводной сети, номер канала, метод кодирования и таблицу подключенных беспроводных клиентов с их MAC-адресами и временем подключения к G-560.

Утилита управления предусматривает два способа настройки устройства: с использованием мастера установки и вручную.

Мастер установки в пошаговом режиме позволяет задать имя устройства, IP-адрес и маску подсети, а также IP-адрес шлюза (в случае применения статических сетевых настроек) или указать назначение сетевых настроек автоматически (с использованием встроенного DHCP-клиента).

На следующем шаге мастер установки предложит задать SSID беспроводной сети и номер беспроводного канала (от 1 до 13). Далее предлагается задать метод кодирования (WEP или WPA-PSK) или отключить кодирование. В завершение мастер настройки предложит просмотреть и подтвердить все сделанные изменения.

Настройка точки доступа ZyXEL G-560 EE вручную предполагает возможность более тонкой настройки. Так, при настройке беспроводного соединения можно указать не только SSID сети и номер беспроводного канала, но и тип сети, то есть указать, что именно используется: только клиенты 802.11g, только клиенты 802.11b, только клиенты, которые поддерживают расширенный протокол 802.11b+, или только клиенты, которые поддерживают протокол 802.11g+. Кроме того, предусмотрено задание смешанного режима сети, когда присутствуют различные сетевые клиенты.

В дополнительных настройках можно задать порог RTS/CTS и порог фрагментации, указать количество подключаемых беспроводных станций, тип заголовка кадра (короткий, длинный или авто), а также активировать трафик между BBS, то есть разрешить сообщение между отдельными беспроводными станциями.

В диалоговом окне «безопасность» имеется возможность указать метод кодирования данных. Точка доступа ZyXEL G-560 EE поддерживает алгоритмы WEP (64-, 128- и 256-битный ключи), WPA-PSK, WPA и 802.1х.

Кроме того, точка доступа ZyXEL G-560 EE поддерживает фильтрацию сетевых клиентов по MAC-адресам.

Еще одной особенностью утилиты управления точки доступа ZyXEL G-560 EE является возможность использования патентованной технологии OTIST (One-Touch Internet Security), позволяющей в автоматическом режиме произвести настройку безопасности сетевого соединения и присвоить свой идентификатор SSID, а также обеспечить правильную конфигурацию алгоритмов WEP или WPA-PSK на всех беспроводных клиентах сети. Понятно, что использование технологии OTIST возможно только в том случае, если беспроводные клиенты сети также поддерживают данную технологию.

Why is my graph all red show 100 packetloss

If your graph is solid red like this example:

BQM graph with ICMP blocked

Then double check that your registered IP address is correct, and that your broadband router that has been assigned this IP address. Check the router is configured to respond to ping requests on its WAN/Internet port. The option is sometimes referred to as ‘reply to ICMP requests’.

We maintain a list of some routers with guides on how to configure them to work with the Broadband Quality Monitor in our .

Our traceroute tool at www.thinkbroadband.com/tools/traceroute is an easy way of checking whether your router is responding, rather than waiting for the graph to update.

The latest version of the Virgin Media Superhub firmware (R36) hides the setting under Advanced settings > Tools > Ping — ‘WAN Ping Respond’, ‘Respond to ICMP echo requests sent to WAN IP’

My graph has lots of varying height yellow spikes is there a problem

A very common type of graph is shown below:

BQM graph showing the effect of hosting (upload) and browsing (download) on latency

The graph above was from a connection, that was hosting a small webserver, and the yellow spikes represent when someone is downloading a small file or webpage from the server. The wider block of yellow spikes at 11:45am represent when the actual owner of the connection, probably started using the connection too.

The connection in this graph is good, as the amount of jitter in the latency represented by the blue area is still very small across the whole 24 hour period.

If you are on a slow connection the action of downloading or uploading lots of data can have even larger effects, e.g. a connection that is saturated by streaming two HD films at the same time will most likely show a large yellow block for the duration of the streaming.

3.2 PPPoE Encapsulation

The NBG-418N v2 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem
(DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection
using PPPoE.

  • (..this is not a complete list so if your product is not listed below, try it out!)

Not Supported*

  • BT Home Hub or Smart Hub
  • PlusNet Hub Zero / Hub One (aka BT Home Hub 5a)

* These routers do not support responding to ping packets on the WAN port, however you can configure a Default or DMZ host which can respond to pings directed at your public IP address; we strongly advise you to only do this if you understand the security implications of running a publicly accessible host on the Internet.

Do you have any specific advice on how to make my router work with BQM

The common settings you will need to look at are usually labelled «WAN Ping» or similar. It will probably say ‘ping’ but may refer to ‘icmp echo’. On some routers, you may need to disable the firewall (not something we recommend unless you know what you’re doing) or use the router in ‘modem’ mode with another router for routing. On other routers, you will not be able to use BQM at all as it has been restricted by the manufacturer (or in most cases, your broadband provider).

Specific router advice is provided below for the more common routers which support BQM.

 If your router isn’t mentioned, please refer to our community forum for advice.

Virgin Media Superhub R36 Firmware

  1. Navigate to routers web interface
  2. Under the Advanced Settings -> Tools -> Ping menu
  3. Tick the WAN Ping Respond box
  4. Apply/Save changes
  5. BQM should soon start showing ping responses, rather than solid red

Virgin Media Superhub (Netgear VMDG480)

  1. Login to the router using your web browser at http://192.168.0.1 (this is the default IP address; if you have changed it, you will need to update it)
  2. Enter your username/password. The default settings will be found on a label at the back of the superhub under «Superhub settings» and will probably be ‘admin’ and ‘changeme’ respectively.
  3. On the next screen, find the ‘Advanced Settings’ link at the bottom of the page
  4. Under the ‘Advanced’ sub-menu click on ‘Ping’
  5. Finally, ensure the tickbox is checked after ‘Respond to ICMP echo requests sent to WAN IP’ and click ‘Apply’.
  6. That’s it! you should be done. Just don’t forget to check back regularly (we would recommend weekly) to ensure your IP address has not changed–otherwise you may be monitoring someone else’s broadband line

NetGear DGND3300 / DG834GSP / DG834N

  1. Login to the router using your web browser. (Type http://www.routerlogin.net, or http://www.routerlogin.com, or the router’s LAN IP address (default is 192.168.0.1) in the address field of your browser, and then press Enter).The default username is «admin» and the default password is «password».
  2. Once logged in on the left you will have a menu, scroll down to the «Advanced» section and select «WAN Setup».
