CHECK FOR PACKET LOSS ON A MAC DOWNLOAD
I am downloading something and then the download stops suddenly and I have to start again. The problems are several micro interruptions on the internet connection, kind of lags, that is probably related to timeouts on their proxies or in my connection to their network.Īs these micro interruptions occur at random, I cannot prove that, because every time they send a technician to my office the problem is not detectable, specially because the service may be stable for 3, 4 hours and then start to show the problem again. VoIP would most likely be unusable.I have subscribed to a new ISP and I am experiencing problems with this new ISP. You should see a noticeable delay for all network tasks. You may see delays or freezing while browsing and have significant quality issues with VoIP. Web browsing shouldn't be affected but you will most likely notice quality issues with VoIP. You may notice the rare issue with VoIP but still acceptable for most. Practically unnoticeable web browsing delays. The higher, the more spread out they are. The lower the standard deviation, the more closely clustered the times are. Stddev - Stands for 'Standard Deviation', which represents a measure of the spread of times.Max - The maximum amount of milliseconds a signal took to go from your network, to the IP address specified, and back to your network.This value is calculated by adding up the total amount of milliseconds then dividing that sum by the number of packets that were sent. Avg - The average amount of milliseconds a signal took to go from your network, to the IP address specified, and back to your network.Min - The minimum amount of milliseconds a signal took to go from your network, to the IP address specified, and back to your network.The second line to look at is round-trip min/avg/max/stddev = X/X/X/X ms Any positive value indicates a potential issue on your network that and you may need to reach out to your Internet Service Provider to troubleshoot. Ideally, you would want to have a 0% loss. Having any packet loss could cause noticeable issues. Packet loss - This is the important number.Packets received - Tells us that the recipient IP address received your signal and replied back to you.Packets transmitted - Indicates a signal that has been sent from your network to the IP address specified.The first line to look at is X packets transmitted, X packets received, X% packet loss Allow the test to complete and show the summary.Click on the Ping tab at the top, enter 8.8.8.8 into the address text box, then click the Ping button.Navigate to your Applications folder and double-click Network Utility.Average - The average amount of milliseconds a signal took to go from your network, to the IP address specified, and back to your network.Maximum - The maximum amount of milliseconds a signal took to go from your network, to the IP address specified, and back to your network.Minimum - The minimum amount of milliseconds a signal took to go from your network, to the IP address specified, and back to your network.The second line to look at is Minimum = Xms, Maximum = Xms, Average = Xms Received - Tells us that the recipient IP address received your signal and replied back to you.Sent - Indicates a signal that has been sent from your network to the IP address specified.

The first line to look at is Packets: Sent = X, Received = X, Lost = X (X% loss)
