As an Alternative to the Repeater you can also use your Laptop as a Wi-Fi amplifier to use a private HotSpot on the PC or your phone as a Repeater use.In order to increase your WiFi range and provide a continuous network coverage. How will also show you the 3 best Repeater and betrayed, as you have a Fritz-Box as a Repeater the setup. Is your Wi-Fi reception is poor, you can also the range of the WLAN increase, by sources of interference, eliminate them, and a Repeater set up.So you should avoid, for example, Lead paint, and metal objects in the area of your wireless network. Unitymedia itself offers a number of tips and Tricks for dealing with Wi-Fi.Doesn’t make much sense in my case because the SNR levels on the modem look okay, but anyway he will be there. So far, a Unitymedia guy will be here on Wednesday to check my line. ![]() Sorry for being late, but here are the new graphs:Īs you can see, the problem gets worse on weekends. As you can see, I finally reach the promised 100 Mbits so this evening will be the first day where you can see the full bandwidth drop. But after that, finally I’ve found a new host so the tests can continue. Then suddently the speed test from Unitymedia went down and I was no longer able to test it further so I had to find a new host where I can download test data from.Īt first, I tried my small V-Server but as you can see, it couldn’t provide enough bandwidth. I modified the code now to use five connections at once (code snipped above is updated), but still there was no large increase. This also happend one day before.Īdditionally, you can see that I never managed to get above 50MBit and I was starting to hunt for a bug in my code but didn’t find one. So as promised, here is a graph for the last 24 hours:Īs you can see, there is a huge bandwidth drop starting at about 6pm, lasting until about 1am. Of course, I’ll post a longer graph tomorrow when the script has been run for a longer time. Given the fact that I pay for a 100 mbit line, this is terrible. So while typing this article, the test is now running since some minutes and the first graph can be shown: SetInterval( testBandwidthMultiple, 1000 * intervalSeconds) Syslog.log( "BANDWIDTH", "isp", "Unitymedia" console.log('HEADERS: ' + JSON.stringify(res.headers)) Ĭonsole.log( "size " + size + ", bytes per sec " + bytesPerSec + ", mbit " + mbit + ", " + numRunning + " parts left" ) Ĭonsole.log( "finished, size " + size + ", total bytes per sec " + totalBytesPerSec + ", total mbit " + totalMBit ) Var request = http.get(url, function(res) Knowing how to do it, I fired up Notepad++ and created a small script in node.js that repeats this test every two minutes and dumps the result in a syslog file that I can feed into my small Splunk instance to be able to graph it: var syslog = require('./syslog') The address is called with a parameter called ‚x‘ which is randomized at every new test. ![]() ![]() When analyzing the network traffic you quickly find out that the speed test basically does nothing more than downloading a huge 4000 x 4000 pixels random jpg file and then measuring the time it took to download it: As my internet line bandwidth is terrible every day during „prime time“ (about between 8pm and 11pm) I wanted to create a small test to have a proof to show to my ISP as well as to find out the critical hours.Īs my ISP always tells me to test with a specific speed test (actually it resides on a web page owned by the provider, giving a small distance in hops), I started analyzing what the speed test really does.Īs it turns out, the speed test is a flash application.
