So I called his VoIP phone and asked him to accept a remote desktop connection so I could try some further tests. He came back saying he's getting 4.8Mbps down and 7.5Mbps up. I asked him what speed he's getting and sent him the TestMy combo speed test link. I had an interesting call with my work colleague in the UK who got in Pulse8's Fibreoptic 38Mbps Broadband package, which runs over VDSL. For example, a 4G provider could throttle individual connections at 4Mbps would prevent most streaming services being able to play full HD, yet if one uses the popular Speedtest app which performs a multi-threaded test, it will report a vastly higher test result. Some mobile/cellular and fixed wireless services also seem to throttle individual connections, which effectively reduces network load as video streaming services generally stream at the maximum resolution possible over a single connection. However, as video streaming services only establish a single connection to run the stream, 500kbps is not enough for most streaming services as many require at least 1Mbps to stream at all, yet Ookla's Speedtest will falsely give the impression that the connection is well capable of streaming video when throttling occurs on individual connections. So what I reckon they've done is throttle individual connections to 500kbps, which is just fast enough to comfortably browse the web as web browsers make multi-threaded connections to download all the web page elements, pictures, etc. It mentioned that the complementary Wi-Fi is suitable for general web browsing and e-mail only and in order to stream video, download large files and so on, I would need to purchase premium Wi-Fi access for €8 per hour. I saw a flyer on the table mentioning about high speed Wi-Fi, so was curious to see what it said after my strange Wi-Fi experience. Sure enough, when I ran TestMy in multi-threaded mode, I got over 2Mbps as the test result. However, when I started running simultaneous downloads, each single one continued to run at about 60KB/s. When I started a download in my web browser, it came in at a steady 60KB/s. When I tested with TestMy, sure enough it reported my speed as about 500kbps consistently, which explains the YouTube playback problem. Going by Ookla's Speedtest, it looked reasonably good with a 2Mb download test result, yet when I tried watching YouTube, it would only play in 240p with a grainy picture even though I know 2Mbps is plenty to play videos at 480p and some even at 720p. While on a business trip in Germany, I stayed at a Leonardo hotel which had plenty of advertising about having free Wi-Fi. This potentially also explains why some users who get fast results on Speedtest have problems with video on demand services repetitively buffering or showing a grainy low resolution stream. While multi-threaded tests are great at determining the maximum bandwidth available on an ISP's connection, it does not show what one will get when streaming video or even downloading a large individual file. Then again, this ISP also uses a carrier grade NAT, so if it did have access to the logs with IP addresses, it probably couldn't map them with each logged IP address being shared amongst many customers.Īnother problem I noticed with Ookla's app is that it does not provide the ability to perform a single threaded speed test. during the brief periods my uplink worked. I'm not sure if this ISP has access to the test results since it hosts an Ookla server, but if it does, they'll obviously be skewed as the only test results it would have logged from my end were the ones the test successfully completed, i.e. That's as far as it gets, even when I check an hour later - It stalls like trying to drive a manual gear stick car below 5MPH without pressing the clutch. When the uplink is running slow, this is what happens when I run the Ookla's Speedtest: While Ookla's browser based Speedtest seems to measure the link during the brief periods the uplink is running quick, I have yet to see it record a single speed test with a result below 0.1Mbps. My fixed wireless ISP's connection has had an issue for over a month now where the uplink struggles to perform better than 0.1Mbps, then intermittently spikes to about 9Mbps as shown below: Testing very slow connections (especially uplink):īased on my experience, Ookla's browser based Speedtest can't seem to handle connections below about 0.1Mbps, at least on the uplink.
