how to fix bufferbloat
Bufferbloat is a term used to describe the condition of a network where the buffers used to store data packets are too large, leading to queuing delays and packet loss.
There are several ways to fix bufferbloat, depending on the cause of the problem. Here are some tips:
1. If the problem is caused by a slow upstream connection, you can try using a proxy server or caching server to store copies of popular websites and files locally, so that they can be accessed more quickly.
2. If the problem is caused by over-sized packets, you can try using a tool like netpipe or iperf to measure the maximum throughput of your network. If the throughput is lower than the maximum bandwidth of your connection, you can try using a tool like iptables to limit the size of packets that are sent through your network.
3. If the problem is caused by a lack of available bandwidth, you can try using a tool like Wireshark to identify which applications are using the most bandwidth, and then try to optimize them or restrict their use.
4. If the problem is caused by latency, you can try using a tool like ping to measure the latency of your network, and then try to optimize the configuration of your network devices to reduce the delay.
5. If the problem is caused by congestion, you can try using a tool like tc to create a QoS (quality of service) policy that will give priority to high-priority traffic, such as voice and video applications.
6. If the problem is caused by a misconfigured router, you can try using a tool like traceroute to identify the source of the problem, and then try to fix it.
7. If the problem is caused by malware or spyware, you can try using a tool like malwarebytes to scan your computer for and remove any malware or spyware that may be causing the problem.
8. If the problem is caused by a faulty driver, you can try using a tool like ndiswrapper to reinstall the driver.
9. If the problem is caused by a faulty network card, you can try using a tool like ethtool to change the settings of the card.
10. If all else fails, you can try using a tool like DD-WRT to reconfigure your router to fix the problem.

What causes high bufferbloat?
Bufferbloat is a term used to describe the excessive buffering of packets that can occur in networking equipment, causing a degradation in performance.
Bufferbloat can be caused by a number of factors, including:
– Incorrectly configured network equipment
– Congestion on the network
– Excessive buffering on the client device
Buffering can occur on the client device, the network, or the server. When buffering occurs on the client device, it can be due to a lack of available memory or due to a slow network connection. When buffering occurs on the network, it can be due to congestion on the network or to a lack of available bandwidth. When buffering occurs on the server, it can be due to a lack of available memory or to a slow network connection.
Incorrectly configured network equipment is often the root cause of bufferbloat. When network equipment is configured incorrectly, it can result in excessive buffering, which can lead to a degradation in network performance.
Congestion on the network can also cause bufferbloat. When the network is congested, packets can be queued for a long time, which can result in excessive buffering.
Excessive buffering on the client device can also cause bufferbloat. When the client device has a slow network connection, it can result in excessive buffering, which can lead to a degradation in network performance.
There are a number of ways to address bufferbloat, including:
– Configuring network equipment correctly
– Reducing the amount of buffering on the client device
– Addressing congestion on the network
Configuring network equipment correctly is often the best way to address bufferbloat. When network equipment is configured correctly, it can help to reduce the amount of buffering that occurs, which can lead to a improvement in network performance.
Reducing the amount of buffering on the client device can also help to address bufferbloat. When the client device has a slow network connection, it can result in excessive buffering, which can lead to a degradation in network performance. By reducing the amount of buffering on the client device, you can help to improve network performance.
Addressing congestion on the network can also help to address bufferbloat. When the network is congested, packets can be queued for a long time, which can result in excessive buffering. By addressing congestion on the network, you can help to reduce the amount of buffering that occurs, which can lead to a improvement in network performance.
Can bufferbloat cause packet loss?
Can bufferbloat cause packet loss?
Bufferbloat is a term used to describe the excessive buffering of packets that can occur in some networking scenarios. When bufferbloat is present, packets can be delayed or lost, which can lead to poor network performance.
One of the most common causes of bufferbloat is a congested network link. When the link is congested, the buffer in the network device can fill up, leading to delays and packet loss.
Bufferbloat can also be caused by inappropriate buffer sizing. If the buffer size is too large, it can fill up and cause delays and packet loss.
In some cases, bufferbloat can be caused by a faulty network device. If the device is unable to handle the amount of traffic it is receiving, it can start to buffer packets excessively, leading to delays and packet loss.
Bufferbloat can also be caused by incorrect configuration of network devices. If the devices are not configured correctly, they can start to buffer packets excessively, leading to delays and packet loss.
So, can bufferbloat cause packet loss? In many cases, the answer is yes. If the network link is congested, the buffer can fill up and packets can be delayed or lost. If the buffer size is too large, it can fill up and packets can be delayed or lost. If the network devices are not configured correctly, they can start to buffer packets excessively, leading to delays and packet loss.

How do I fix Bufferbloat for free?
Bufferbloat is a problem that can occur when a router or other network device is overwhelmed with too much data, causing high latency and packet loss. While there are a number of ways to address bufferbloat, many of them require expensive hardware or software.
However, there is a way to fix bufferbloat for free, using the qdisc tool that is included with most Linux distributions. qdisc can be used to throttle the flow of data to a particular device, helping to prevent it from becoming overloaded.
To fix bufferbloat using qdisc, you will first need to identify the device that is experiencing the problem. This can be done by running the command ‘ip link show’, which will list all of the network devices on your system.
Once you have identified the device that is experiencing the bufferbloat problem, you can use qdisc to throttle the flow of data to that device. To do this, you will need to create a qdisc file called ’90-bufferbloat.qdisc’ in the /etc/qdisc directory.
The contents of the 90-bufferbloat.qdisc file should look like this:
#!/bin/sh
#
# 90-bufferbloat.qdisc – fix bufferbloat for free
#
tc qdisc add dev ${device} root handle 1: htb
tc class add dev ${device} parent 1: classid 1:1 htb
tc ratelimit per-packet 100000 burst-size 20000
This file will create a qdisc called ’90-bufferbloat’ that will throttle the flow of data to the device ${device}. The tc ratelimit command will limit the amount of data that can be sent to the device, while the tc class add command will create a class for the qdisc.
Once the file is created, you can activate it by running the command ‘tc qdisc add dev ${device} 90-bufferbloat’. This will activate the qdisc and begin to throttle the flow of data to the device.
If you find that the bufferbloat problem persists, you can experiment with different values for the tc ratelimit and burst-size commands to find the setting that works best for your system.
How do I test a Bufferbloat router?
Bufferbloat is a condition that can occur when a router or other network device buffers too much data. This can cause latency and other problems for users of the network.
Testing for bufferbloat can be a difficult process. There are a number of factors that can contribute to the condition, and testing for it can be time-consuming. However, there are a few steps that can be taken to help identify a bufferbloat router.
The first step is to determine whether or not the router is actually the source of the problem. This can be done by running a speed test on a device that is connected to the router. If the speed test results are worse when using the router than when using a different router, then the router is likely the source of the bufferbloat.
The next step is to test the router for bufferbloat. This can be done using the bufferbloat test tool, which is available on the website of the Coalition for Better Internet. The tool can help identify routers that are suffering from bufferbloat, and it also provides information on how to fix the problem.
If a router is found to be suffering from bufferbloat, there are a number of steps that can be taken to address the issue. One solution is to use the bufferbloat patch, which is a software patch that can be applied to routers to help reduce the amount of data that is buffered.
Another solution is to use a router that is specifically designed to address the issue of bufferbloat. These routers typically have firmware that is specifically designed to limit the amount of data that is buffered.
Bufferbloat can be a frustrating problem, but there are a number of steps that can be taken to address it. By using the bufferbloat test tool and taking the appropriate steps, it is possible to identify and fix a bufferbloat router.
