    Stuttering and cpu usage

    Check the PC's BIOS set up to see if there are any floppy drives configured. If there is any an 1.44MB drive listed, change it to 'None'. I have come across a similar issue before where some older motherboards automatically add a 1.44MB entry if the BIOS CMOS is reset, such as after replacing the CMOS battery. If a floppy drive is configured and there is no floppy drive connected (which are obsolete anyway), Windows will stutter terribly, especially when opening the file explorer.
  2. That made a big improvement on the ping test here to the UK server: The speed tests are about equal now between the two servers: I never thought of checking the ping latency the last day. Usually when the speed drops below around 5Mbps, I run a ping test and trace route to check the latency.
  3. Over at least the past week, I've been having problems running speed tests with the UK TestMy server, which CA3LE reckons is due to routing issues affecting my connection. I just want to check if anyone else in Ireland/UK is having a similar issue, i.e. much lower download/upload speeds with the UK server compared to the German server and high latency with packet loss pinging the UK TestMy server. The following is a speed test from my end against the UK and German servers in regular linear mode. My home connection is 4G based, so it's normal for me to get under 10Mbps in the evenings due to cellular contention. However, it has been very unusual for me to frequently get much lower test results with the UK TestMy server than the German TestMy server. The following is a trace route to uk.testmy.net from my connection: A ping test to uk.testmy.net with 100 pings from my connection: A ping test to the second last hop ( gives an average ping of 54ms and no packet loss. Finally, a ping test to de.testmy.net gives an average ping of 62ms and no packet loss.

    No subforums for fixed wireless?

    Going by the database log, it looks like the majority of the high test results (~54Mbps down) are with the same connection ID. This could be someone that is connected to a wireless mast with very few other customers and running a repeat scheduled test. There haven't been many discussions here about fixed wireless Internet, which is likely why there is no sub-forum here. If you have 4G LTE coverage with any cellular provider, see if that provider offers mobile broadband with 4G LTE connectivity. The latency will be similar to fixed wireless and the monthly caps are generally much better than satellite. For example, here in Ireland all three major mobile providers (Eir, Three and Vodafone) offer 4G based broadband packages with monthly caps of between 60GB and 750GB. Like fixed wireless, the speed will depend on the network load of the nearest 4G cell and the signal strength. The price will depend on the monthly cap. My own home broadband is 4G based as my only other options are DSL (4Mbps max), satellite and a wireless provider I had terrible experience with. I usually get around 20 to 30Mbps with the 4G service as there is not much load on the Three cell in my area.

    What about DNS response?

    Probably the best way to test DNS response times is with this DNS Query Sniffer utility. This let's you see the individual DNS response times when opening a website. The following is an example loading TestMy in the Chrome browser: Blank response times are probably cached entries and the green indicators on the left indicate successful responses. A red indicator means a DNS error such as an invalid host name. If you see any yellow responses, this can be a sign of packet loss, which with DNS would lead to some DNS look-ups that never receive a response. If the 'Duration' column is showing unusually high figures such as over 100ms or you see multiple yellow icons on the left, I suggest trying DNS over HTTPS to see if it performs any better. This page shows how to configure Firefox for DNS over HTTPS with the Cloudflare HTTPS DNS server. When this is set up, no entries from Firefox should appear in DNSQuerySniffer. If the intermittent lag continues, then it is unlikely DNS related.

    Wireless interference

    Indeed they should definitely offer a lot mor ethan 30Mbps. I used to peak around 60Mbps with my former Huawei router with only 300Mbps over 802.11n (2.4GHz). With my current set-up, a Huawei B525 with 802.11ac, I get around 110Mbps between it and my desktop PC (TP-Link Archer AC1900 USB) based on a load test between the PC and a laptop connected to the router. This is with the Huawei B525 in the loft at one end of the house attached to a pair of LTE antennas and my desktop PC on the ground floor at the opposite end. Based on my experience troubleshooting Wi-Fi performance in the past, nearby power supplies can severely deteoriate the Wi-Fi performance. For example, I remember my brother struggling to get over 3Mbps over Wi-Fi, only to discover his router was on a shelf with its power supply socket directly underneath the shelf. Due to the shelf location, he couldn't move the router and there was just the one power socket nearby, directly underneath the shelf. As an experiment, he placed a sheet of aluminium foil underneath the router. His Internet speed tests over Wi-Fi jumped straight to about 76Mbps, the same as with a network cable.

    Rural Satellite Internet Help

    Unfortunately what you describe is quite common with satellite Internet and very likely down to their traffic management policy. For example, with some satellite operators here, once a certain amount of data is consumed within rolling time period (I think an hour), the maximum speed is halved. This process repeats until basically the connection is rendered unusable until data consumed earlier falls out of the rolling time period. So basically something like a Windows 10 feature update (3-4GB) could render the satellite connection unusable in a very short period of time. If you are getting 3G or 4G/LTE connectivity on your phone from the WeBoost, try running a few speed tests over the phone's cellular data connection at different times of the day. A good 3G (HSPA+) signal with a lightly loaded mast can provide over 10Mbps. If you are able to get over 1Mbps on most of the tests, that will likely give you a much more stable and consistent connection than over satellite, regardless of the 10s of Mbps they claim to deliver. In this case, I suggest getting hold of a dedicated router and data SIM. If you are unable to get out of your satellite contract, it will still be useful as backup or to supplement the cellular data connection, e.g. download bulky files overnight over satellite such as Windows updates and use cellular data for your VPN connection where low latency is more important.
  8. No problem. I had a quick check and toggles back and forth fine now in Edge, Firefox and Chrome while logged out.
  9. This is a screen-recording from my end with Chrome, Firefox and Edge. I uploaded it as an unlisted video on YouTube to embed here:
  10. I cleared the browser cache and cookies, but will try to make a screen recording.
  11. If I am not logged on to TestMy, and switch to Mulltithread mode, the [Linear] button at the top right does not work. Neither does the 'Disable Multithreading' button. Steps to reproduce: Log out of TestMy (or open an incognito/private browser). Click Multithread at the top-right. Click the 'Enable Multithreading' button. Click [Linear] at the top-right. Click the 'Disable Multithreading' button. It will continue to display "MultiI Select" at the top-right, sometimes even with the British flag: I'm not sure if it's related, but if I perform the above steps and then go to the Download page and click the 'Express Test!' button, it display a "Not Found" error page: I checked this with Chrome, Edge and Firefox.

    UDP Speed???

    UDP is a simple connectionless protocol, where data is sent without the overhead of setting up and maintaining a connection. It's effectively the electronic equivalent of mailing packages without any tracking or return address. There is no guarantee they will reach the destination. Unlike TCP, there is no simple way to run a UDP speed test. If UDP data is sent faster than what the connection can handle, UDP packets will be lost. With a UDP based video connection, this will result in dropped or garbled frames or no picture at all if there's not enough data in each frame to decode it. If you are comfortable with using the command prompt, you can try running an iperf3 based test over UDP. With this utility, you specify the test server and the bandwidth to test with. The test will then show the resulting bandwidth and how many datagrams were lost, e.g. due to insufficient bandwidth. A small loss of 1-2% is fine, but if it's over 2% then there is either not enough bandwidth or another issue such as a router dropping packets. With TCP, a small packet loss generally goes unnoticed as TCP will automatically retransmit dropped packets. You can download iperf3 from here. Some test servers are listed here, although from my experience only a small few work with the UDP test. To run a 2Mbps UDP test with it, type: iperf3 -c (server name) -p (port) -u -b 2M The following is an example from my end, running against the iperf.volia.net server:

    Proof of Network Throttling

    That street light sure must have been emitting a lot of interference to interrupt your Internet connection. Based on the faint blow, it probably had a loose or badly corroded terminal that was arcing. It also makes me wonder just how many others in your area were affected. It is surprising the havoc that even a small electric arc can cause. Even the older incandescent blinking fairy light strings were known for interrupting DSL connections.

    Compare your Download Speeds!!!

    My cellular based broadband provider Three made a recent blunder in our area by putting up a cellular mast in the distance that seems to be operating on the same frequency as the local mast. When my router "sees" both, it gets knocked offline, much like trying to listen to a radio station with two stations broadcasting on the same frequency. I've managed to get back online by carefully positioning an antenna such that an obstacle obstructs the direction of the unwanted mast. It seems to work, but with a severe hit on my signal: Despite what appears like a barely usable 4G signal, I still manage to get quite decent speed from the cell, surprisingly from vertical-only polarity: It wouldn't surprise me if many others were knocked off the cell also, freeing up some bandwidth for me. As Three doesn't seem interested in fixing the issue (I reported the issue, but they claim there is no issue), I decided to order a pair (for MIMO) of the most directional LTE antennas I could source to try to isolate the local mast.

    Host Graph

    To me, that seems like either high packet loss or intermittent drop-outs, both which you can check by running an extended ping test while streaming. On a Windows PC, open a command prompt (Start -> Windows System -> Command Prompt) and type the following command: ping -t You should see a continuous run of "Reply from". Leave that window open and start streaming a programme. As soon as the streaming stalls, check the window for any "Request timed out" lines. If you see three or more in a row, your connection had a brief outage. Press CTRL + C on the keyboard to stop the ping utility. Look at '% loss' figure. If that is 1% or higher, scroll up by holding the mouse down on the top-right up-arrow and look out for lines that say 'Request timed out'. If you see three or more grouped together, that is another brief outage. If you come across five or more 'Request timed out' lines in one screen-full, this is a high packet loss issue, which can also interrupt streaming. I've had an issue in the past with at least 3 D-Link routers failing with a high packet loss with this exact symptom, i.e. no issue with browsing or speed tests, but could not reliably stream YouTube.
