I asked practically the same question on SuperUser: superuser. Active Oldest Votes. Add a comment. When debugging a connectivity issue, I split it into three parts: my connection to the ISP that's between me and the gateway at the ISP the infrastructure of the ISP you will have to do a little investigation to find this out, because some ISPs don't disclose their network ranges.
Look at the output of traceroute and do "whois" against each IP starting with your gateway. Up to a certain point they will be assigned to your ISP, that's the internal infrastructure of your ISP the rest of the internet My favorite tool for debugging networking issues is mtr. I will elaborate on them in reverse order: issues outside your ISP.
This is not an excuse for your ISP support to turn around angry customers. They should work with the upstream provider and settle this. Such problems don't happen often, because backbone ISPs have better quality. They might happen if some link went down and traffic is temporarily rerouted over a backup link that has lower bandwidth.
This is the situation when you can be more harsh. Call the support and tell them "Your router with this IP you will see which one in mtr, there will be packet losses there has issues. Fix them and tell me how much time do you need for fixing that. If they said ten minutes and the problem is not getting fixed, call again after ten minutes.
Never say "internet is not working" or something like that. Tell them exactly what the problem is, if you can figure it out, this will make them understand that you know the tech part and they won't get away with silencing you by providing some silly tech excuse.
These can be harder to debug, because there are many factors involved. They can happen because your network card went faulty. But they also can happen because you get ADSL over an old phone line and the signal is bad. This is already the headache of your ISP, it shall replace your phone line to meet the standards.
They are very sensitive about such matters and this is one of the reasons why a lot of ISPs don't have their own tech support forums for customers, because every reported issue is bad PR for them :- As correctly pointed, monopolies, especially government-linked ones, are another pain. There are a couple of workarounds here that can help mitigate the problem: use alternate DNS servers: the ones from google or from opendns.
I've used pdnsd and it did the job very well for me. Evan Anderson Evan Anderson k 18 18 gold badges silver badges bronze badges. Although data can be transferred quite fast , there could still be restrictions on the service itself. Your ISP might offer different package levels and the cheaper option is limited in the amount of bandwidth that can be consumed. More expensive packages might have generous or unlimited usage caps.
With video streaming, online gaming services like Steam and P2P downloading etc, far more internet data and bandwidth can be used than you might expect. There may be other computers on the network consuming more than they should , causing an overall slowdown of the internet service. An easy way to do that is running a program that monitors and logs how much internet bandwidth a computer consumes over hours, days, weeks or even months.
Here are 5 free tools to try that can monitor and log your internet traffic, all have been tested in Windows 7 and Perhaps the most well known network monitoring and logging software is NetWorx.
Other pluses include the fact NetWorx is constantly updated by its developer, SoftPerfect, and both portable and installer versions are available. While the NetWorx tray icon does not show an animated speed meter by default, you can easily turn it on and have bars or a mini graph by going into the settings. A resizable graph can be shown so you can see what has been uploaded and downloaded in the last few minutes. To go back further in time right click the tray icon and select Usage Report, this gives a wealth of statistical information.
Other notable features include a speed meter to test network throughout, a traffic quota system that can show a warning or send an email when a certain amount of bandwidth has been reached, and a notification feature that performs a number of actions when an amount of traffic has been sent or received.
NetWorx can also setup quiet hours, connect with other instances of NetWorx on your LAN and control dial-up connections. Download NetWorx. Sadly the NetSpeedMonitor program is no longer in development and its website has disappeared. After install you will be asked if NetSpeedMonitor is to be added to the taskbar. Then a settings window requires selecting a language, the monitored network interface and whether to log traffic to a database. After that is done an upload and download speed meter will sit next to the system tray in the taskbar.
Hover over the meter to get sent and received statistics for the session, day or month. Pingdom Website Performance Monitoring is our first choice! It uses a mix of synthetic and real-user monitoring to give you detailed insights on how your site is being used.
We were impressed by the granularity of the application performance insights whcih is great for getting ot the bottem of bottlenecks and issues. This module specializes in examining the network traffic on local or remote networks. It is also able to measure the performance of links between networks and also connections through to cloud resources, thus, it can measure internet connection performance.
The service requires an agent program to be installed on the monitored network. Thus, in order to see live information about traffic flows across the internet, the systems administrator would need to install the agent on at least two sites. Another method of measuring internet connections with the Network Performance Monitoring unit would be to place an agent on a cloud server and then an in-house host.
The agent will scan all traffic to identify all of the devices connected to the network and this activity enables the monitor to maintain a live topology map of the network and a device inventory. If agents are placed on several sites, the internet links between them will also be integrated into the network topology maps.
All of the data processing of this monitor takes place on the Datadog server — the agent is a data collector that feeds into those processes. The console is resident on the cloud server and customers gain access to it through any standard browser.
The network performance screens show live traffic flow data and Datadog also stores statistics so that performance over timer can be analyzed. The analysis features of the Network Performance Monitor enable network managers to plan capacity for expected demand both on private networks and in terms of an internet service agreement. Datadog charges for the Network Performance monitoring tool by subscription.
The company offers a rate per month and a cheaper rate per year. In both cases, the subscriber pays per host. The utility includes many different sensors. Each sensor is actually a separate monitoring program. These tests give you a live view of internet access speeds for your site. So, you can see how long it takes members of the public to get to your site anytime during the day. The internet monitoring tool has the Ping function at its heart. So, if your internet service suddenly stops working, you will know right away and be able to take action.
As well as seeing a line graph of access times from three different locations, you will be able to set the system to notify you when the internet service performance drops. These notifications can be delivered by email , SMS , or pager alert. The PRTG internet monitor checks on more than just site availability. You can also use the tool to ensure that all elements of the site are loading properly. You can also use the tool to check on the real user experience, performing a run-through of the full buyer path from an initial visit to a purchase.
This enables you to check that database access is efficient and that your shopping cart software is working properly. The monitoring capabilities of PRTG are not restricted to your own website.
You can also check other sites on the internet. Thus, you will be able to compare the response times of your site compared to rival sites. The PRTG package includes a lot of monitoring utilities. Problems with your website response times might not be caused by your internet service. Server and application performance, and also internal network response times can impact on-site delivery times. With the full PRTG system, you can check for the cause of any internet response time problems and drill through your system to find the exact cause of the fault.
Overall PRTG is great for monitoring internet availability and performance because it blends monitors for networks, servers, and applications. Websites involve every level of the stack and so problems with internet performance can have any of a long list of causes. Paessler PRTG includes features such as stack visualizations that make it clear where the source of a performance problem lies. PRTG is customizable and the customer only pays for those monitors that are activated.
You can get a day free trial with all sensors available. Paessler charges for PRTG in service level bundles. Each charging band is calculated on the number of sensors that you activate.
