So I had a theory that the 8 channel SB6141 may perform better. I just had to know so I went through the hassle and swapped my modem again. I swapped the SB6183 for a SB6141 and you know what... it's faster. SB6183 (16 channel, $129.99) Comcast Ultimate 150/20 I tried two SB6183's and they both displayed this slow response. Never getting near my old SB6121 or this SB6141 in terms of starting out fast. Always took seconds to ramp up, unless multithreading. SB6141 (8 channel, $89.99) Comcast Ultimate 150/20 (only 25 minutes later... nothing changed besides the modem swap, same variables.) Now this is more like it. Instantly apparent that this modem initializes the connection much MUCH faster. I don't know why this is... but for my Internet package the 8 channel SB6141 performs better. TestMy.net results are proof. The other modem started so slow this one just POPS right up instantly. Looks like people can save their money and actually have a faster responding connection.

Looks like you normally get 15-20 Mbps but like you said, right now you're only getting ~1 Mbps. If your PS4 is downloading a game... that would totally explain why your speed would drop like that. Any network activity that's drawing bandwidth off the Internet will affect your results. Whatever is speed it's being downloaded at... you can pretty much figure that amount will come right off the top of your results. Say I have a 10 Mbps connection and I'm downloading something at 1 MB/s (8 Mbps) --- I'm only left with 2 Mbps to test with (or do anything else). Your connection is a 20 lane freeway... 19 lanes are most likely being taken up by your PS4 download right now. If your router has QoS settings you may be able to alleviate some of the symptoms on the rest of your network by deprioritizing the PlayStation traffic or setting your computers to a higher priority. Here's some info on setting up QoS on netgear routers. Concept is the same for other routers.

You posted it alright, I was able to see the issue it just disappeared right away because it only took a second to fix. Now I see the same thing in EBrown's sig. ... except this time it was missing that update all together. Updated.

Fixed. Thank you for pointing that out. A variable needed to be added to the combined output. Like you said it was showing the correct local time but was saying GMT -7. All the times used to be in GMT-7... that wording had to be replaced with a variable. How it works now is it will show in GMT unless you've visited TMN. If you've visited TMN there's a cookie that I set and reference to adjust to your local time. The next version will show the time relative to the user referencing the result and also tell what time it was in relationship to the person who was taking the test. The results above, to me, show as 9am ... but that's what time it was where I am when you took the test... the next version will include your timezone data. The data is logged now so it just needs to be referenced and displayed. --- so you're GMT+1 ... I'm GMT-6 so the actual time you took the test was at 4pm, right? Definitely important information if you're troubleshooting with someone across timezones. I'll work to make it less confusing and more informative. Thanks again! Which means you haven't been on the speed test side of the site since you last cleared cookies. Hit the homepage then refresh this page and those images should change to show YOUR time. That's what "local time" means.

... why not find another provider who will deliver? Do you have limited options in a remote area or something? If I ever felt lied to or given the run around... I'd be shopping for a new provider. Surely they aren't the only game in town. You shouldn't have to multithread to pull your full speed. You didn't have to before. Multithread is where you're downloading from multiple sources or splitting a task into a bunch of processes vs one process. Multi-homed is different, that's where a computer or device is connected to multiple networks to increase reliability. e.g. TestMy.net's servers have multi-homed bandwidth from over 25 tier 1 providers. You connect through only one provider at any given time but having those options there increase reliability and decrease network congestion.

Let's see what you get with the multithread speed test and then we can make a better assessment.

Does your web browsing slow down significantly when you're seeing the issue?

Well I got home this afternoon and our Internet is out. Comcast reports no outage and the cable TV is working fine so I assume the SB 6183 took a dump. Power cycled the modem a few times, in the modem it's showing... I'll swap it out at Best Buy... maybe it was bad from the start and that's why it was initiating so slow. I've had countless Motorola Surfboard modems. First time I've had one die.

Welcome! Sorry I'm just getting to this topic, getting over a nasty cold... well over a week but I think we're at the tail end now. Thanks, I appreciate that. Seriously, some people need to try out 2 Mbps down and 1 Mbps up before they complain... but then again, 2 Mbps was something to be jealous of back in the day. Sh*t, your 1 Mbps upload, I didn't see that at my house until... June 06 2006! Thought it was faster by then but I guess not. Your upload is fast compared to your download. Right now on the test results page... Comparing to yourself it's calculating your last 5 results for each test type. Comparing to your city, country and ISP (provider) it's calculating the last 30K results. Index is calculated every 2 minutes based on all tests for each type world-wide. There's a problem with that, if a large percentage of people all tested at the top of the hour at the same time it could cause issues. Especially if they all had massively powerful connections. The way it is now, there are often many people testing at the same time at any given time but not thousands who all decide to hit at the exact same time each hour. I'd worry about that feature on scale... especially if the site is hit with redit traffic again. I like the idea... maybe could be implemented where the system checks how many other people are scheduled during that time and will only allow a certain amount of people in each slot. TCP Optimizer can only help when the bandwidth is there to begin with. I think you're probably utilizing the connection to it's full potential... it's just lacking potential. Can you get any cable provider at your house? I'm guessing you've already exhausted your options, huh? You're welcome. Happy to help. Thanks for your continued patronage.

One of our members reported this private message today. I wonder if this guy knows a Nigerian Prince I doubt very many people got this message here, we use PM flood control so the person could have only sent a maximum of 5 in 24 hours. I think they specifically target recent posters who they know are active members. I wanted to post this for other people who may be searching for info on this message. If you get this message or anything similar, it's a scam. If anyone wants to eff with this guy (pretend you're falling for it or something) PM me for the email address. -- I just want to read the emails later.

So the SB6183 (16/4 vs the SB6121 4/4 channel) increased my speed but not totally. Ramp up to full speed takes a second or two when before it was nearly instant. Note how the middle variance went up and TiP minimum is much lower. Hurts the overall score. Above is actually an exceptional result right now... below is more typical... Sure... it ends up faster but because of the weak start it scores worse on TMN's linear test. Multithread and Mercury tests it performs totally different all together. Here's the best I've seen... (using sites.google.com Mercury Speed Test) This is not typical... I watched it burst when I got this result. My network controllers confirm bursts of up to 33.2 MB/s (266 Mbps) but once engaged transfers are chugging along at an average of 23-24 MB/s (~185 Mbps) Same Mercury test a moment later that didn't burst... (in getting this screenshot it sustained the faster speed for the longest I've seen... usually just see short bursts, like at the beginning of the graph above.) Linear results are showing me that there's room for improvement, the other modem initiated quickly... why can't this one? TMN didn't change. Nothing else changed... Looking at the levels.. Thanks again tjritter79 for letting me know about that modem. I'll get it dialed in. If this modem initiated as fast as the other one I'd expect to see 170-185 Mbps consistently with the linear (single thread) test. Again, this is why linear is the default. Multithread is important too but can make things appear better than they really are. The classic test is still the true benchmark to beat. IMHO these results clearly illustrate that. Downloading files off usenet (Giganews, 50 threads) Much faster than before.

You'll still be able to test with Google's servers just not the exact same way. You'll have to use the Mercury Speed Test system. Here's one that works awesome for me all the time. lh3.googleusercontent.com Mercury Speed Test Result I just ran on my laptop... Using that same test on one of my commercial connections I was able to see nearly 600 Mbps, again... confirmed by the client network controller. Google has very fast bandwidth and very quick responding servers, ideal for this test. You can search the Mercury index for other Google Speed Tests or make your own to nearly any web server you want to test against. Not many people realize that TMN does this. Find one that works good for you and bookmark it. If you like the Google tests, go to the Google Speed Test page, scroll down and click "Custom Index"... then when you visit testmy.net/mercury it will show your favorites. You can custom index by city, state, country or ISP (that the test is hosted on). Happy Testing!

I didn't realize that 16 channel modems were out, I'm going to pick one up right now! http://surfboard.com/products/sb6183/ SICK! A Comcast sales person came to my door a few weeks ago and was trying to get us to upgrade to the 150 package. I was like, "what?!" I thought I was paying for the fastest? --- wanted me to resign a contract. I shut the door. --- looking at the website... WTF! Been putting off the call to Comcast to see what's up but just now called and the girl tells me that the website is totally misleading and that I already have the Extreme 150. The sales person who came to my door was a total scammer! Just wanted to get me back in contract. Mother f&*%&*! So NOW... I'm pretty sure that if I swap for this 16 channel down modem it will bring the speed over 150 Mbps. My current modem is 4 down 4 up. Thanks for cluing me in.

You should always purchase your own modem. Don't buy it from your provider either, don't even let them give you one. Always do your research on the modem, even if you're not going to use it's full capability... in the future you may. Motorola owns. If you get the best model (usually for around $100) and pair it with a great N-600+ or AC router (Netgear owns here IMO) you can't go wrong. So side from saving money why should you always purchase your own? Especially with Comcast... Because Comcast USES their customers who have leased modems. If you have one of Comcast's modem/router combos you're not only broadcasting your own private wifi but also Comcast's public wifi network. People can hop on your modem and draw your bandwidth. They don't access the Internet from your IP but they do draw bandwidth from your modem. You can now call 1-800-XFINITY or visit http://customer.comcast.com/ to disable this "feature". But in my experience, even without that... their modems suck. They're huge and you don't want to combine your router and modem. I change my routers out more often than my modem needs to be changed... More info > Comcast sued by customers for turning routers into public hotspots You can get much better supported routers in the open market that will give you a much richer feature set and technologies behind them. IMHO it's always a dumb move to get modems and routers from your provider. ESPECIALLY if they're a combined unit. YUCK! No thanks. If they gave one to me... I wouldn't even sell it or give it away... I'd disassemble it for fun, see if any parts could be salvaged. Get that public wifi out of people's houses! It's a disgrace and they should be ashamed for doing it without really telling people. Hey Comcast, install that crap out in your pedestals at the street and pay for your own electricity!

So you can still browse the site but when you go to start a test the page is blank?

No problem, glad that you've got it all figured out. By the way, you've earned enough trust now so you no longer have to wait for posts to be approved. Happy Testing!

Thanks... I'll look closer and see what they're doing over there.

depends on the bitrate.

It must be add-ons or something specific to your machine. I test as expected using SeaMonkey. I could try on windows too but I'd bet money it works as expected. :::..

Here's how it works. You modify your query to show the way you want... then click "Share This Query" under the graph. The resulting link will display the page to others the way you see it. Here's what I get when I do max results. https://testmy.net/stats/?&t=u&l=100&q=dpitman You only have 86 results right now so max results are 100. As you test more the link above will only show the first 100. Change 100 to 1000 and you can extend that. Hope this helps

As long as you don't mind clearing your settings and addons... this is what I would do at this point. Go to Chrome settings, scroll down and click on "Advanced Settings" then scroll to the bottom and click "Reset Settings" to Restore settings to their original defaults. This is what I would do at this point. Whatever is causing the issues if it's affecting the way the test loads it's most likely affecting the way other sites load as well. Like I said, sometimes just the fact that TMN loads at all is itself a test. It's designed to load the same on any device, any browser... something that's been tested by millions in every scenario under the Sun. So when it doesn't load... it's a strong indication something isn't right. Let us know how it goes.

Sorry, TMN doesn't have an API yet. Maybe released with the next version.

Love it! Thanks for the post!

The Google CDN is being depreciated so that will no longer be an option soon. Just a heads up. I'll work on more alternatives. Bummer.

Hi ohbothersaidpooh, sorry you're having problems. Whether in disappointment, "Oh bother." or in anger, "Oh bother!" it was truly Pooh's way of politely saying "Damn it". Eeyore was always my favorite. Watching and reading it with my daughter now and he still cracks me up. You're making me blush. Do you have wifi and a smart phone or tablet? Any other device really... laptop, other computer. Get connected to the same network and test. If you're able to test (which I bet you will be) then we've established Are you running through a VPN? These can cause issues. TMN is capable of testing VPNs but I've seen odd behavior with certain types. Especially web based anonymizers. That's actually the only time on a healthy connection I've seen things like you're describing. When those are disabled things instantly return to normal. Whatever is causing it... it's a clue to an issue that is most likely affecting your speed in some way. Sometimes when I test a device I don't even need to see the result. I can feel by how the test loads if the device is running great. The progress bar itself loads in different ways depending on how the data is flowing and how the device is processing. This was not intentionally programmed to do this... it just does it. If you use TMN enough you'll have a feeling for what it means when that bar reacts differently. It's very hard to explain but I'm sure others experience can back me up. Just seeing the progress bar (not even having to know how much data is being transferred) you can see fluctuations, jumpiness in the updating... in the linear download test this directly correlates with the data being loaded. You want to see a nice smooth transition across the entire progress. Software and hardware issues can cause the progress to jump. Multithread's progress is always jumpy, because multiple elements can finish simultaneously. Speaking of multithread. Try a multithread speed test. It may run when the linear test won't. Let me know. And let us know if you figure out what's holding you up. It may be causing unexpected behavior on other sites and you may not even realize it yet.
