Internet speed 300mb yields only 40-50mb via wireless
An simpler explanation, my internet is 300mb.

If I use: Internet -> modem -> cable -> Pc. I get 300mb

If I use: Internet -> modem -> wireless -> cellphone. I get 300mb

If I use: Internet -> modem -> cable -> router configured as access point > wireless > cellphone as close as possible to access point. I get 40-50mb

If I use: Internet -> modem -> cable -> router configured as access point > cable > PC. I get 90-100mb

Is that normal? Is there any config I must change at the acess point to fix that?2804:7F2:590:9A24:C859:2050:493C:3F0D (talk) 02:13, 1 May 2020 (UTC)
 * Two things:
 * By "gb" do you mean "Gb" or "gigabits"? Are you measuring this with the same units across the board?
 * How are you measuring your speed? What destination are you reaching in order to benchmark it? What methods and protocols is the benchmark using? Elizium23 (talk) 02:15, 1 May 2020 (UTC)
 * Same measurement across the board, at computer I use speedtest site and at cellphone I use their program.2804:7F2:590:9A24:C859:2050:493C:3F0D (talk) 03:23, 1 May 2020 (UTC)
 * Well... it occurs to me that 300 gigabits is an absolutely massive speed for anyone other than a supercomputer or Google data center. What network cards and media are you using to achieve 300Gb? Surely it is not copper-based. I will not ask how much your ISP charges you as a consumer for a 300Gb Internet connection, but it must be extraordinary.
 * In my major metropolitan area, one or two ISPs are rolling out 1Gbps connections to most urban locations. There is no ISP providing more than gigabit service. The maximum signaling bandwidth for DOCSIS modems is 10Gbps, and you are achieving 30 times that. Wireless, 802.11ac can achieve perhaps 3Gbps, and you've topped that by a factor of 30. Remarkable. Absolutely incredible. Elizium23 (talk) 03:30, 1 May 2020 (UTC)
 * I agree 300Gbps or even 40-50Gbps is simply not plausible. I imagine the OP must have meant Mbps but some clarification would help. BTW there are 10Gbps trials over fibre including for residential areas in NZ [//company.chorus.co.nz/chorus-supercharges-new-zealands-broadband-10gbps-trial]. Everyone else covered by fibre (which I think should be 75% of the population by now) should be able to get close to 1Gbps (it's generally advertised as 950Mbps given the limitation from overhead etc). Also since I have 1Gbps, I know from discussions and some limited experience that if you are testing 1Gbps using the "site" which I take to mean the website over a desktop browser doesn't always work properly. Limitations of the system (browser etc) mean the speeds can be slow. It's generally strongly recommended to use the app (there is a Windows 10 app) or something similar if you want to ensure accurate test speeds at 1Gbps.  It sounds like maybe the app can handle 10Gbps [//www.speedtest.net/insights/blog/10-gbps-speedtest/] although I wonder if it consistently can or it depends on the system. Of course this assumes the testing server even can and your connection to it can by which I don't just mean your last kilometre (and well your system can).  I'm doubtful even the app can handle 300Gbps probably not even 40-50Gbps noting of course that 300Gbps likely exceed the speeds of PCI Express v4.0 x16 and pretty much anything close to being a normal SSD.

 * There is also the question of why on Earth would the average citizen need even 1Gbps for personal use. Make work I say 89.172.65.59 (talk) 04:55, 2 May 2020 (UTC)
 * Who needs i7 and i9 processors? Who needs 256GB RAM in a desktop computer? Who needs 8K graphics at 150MHz in their monitor?
 * Answer: gamers with more money than sense. And the gamer demographic, or at least its mentality, can keep ISPs pumping up the numbers and, accordingly, the monthly fees.
 * I downgraded my bandwidth last year and I've been thankful for two things: I've never missed the extra, and my bill has stayed steady and manageable ever since.
 * Perhaps families with 7 children and 24 devices need a gigabit Internet connection, but I doubt anyone with a family like that has an address that qualifies for it! Elizium23 (talk) 05:09, 2 May 2020 (UTC)
 * Just because people don't "need" something doesn't mean there is no advantage to make up for their cost difference for the particular individual. I mean after all a lot of people spend like $23 on barista coffee a week when they could spend $3 to make it at home. Other people will spend $30 for a meal for one sitting, when they can spend $10 for a meal which equally satisfied their dietary and time requirements. Someone else may choose to spend $25 on a movie at a cinema with popcorn for one person, when they could wait 3-6 months and rent it for $5. Clearly no one needs any of these, but many people do it anyway. I mean even the $5 for a movie rental or $10 for a meal for one person is pushing it. Heck, more controversially, I'd even argue spending $5 a week or maybe $20 for a one time Uber to go to church is something few people need. Ultimately people choose how they spend their leisure time and disposable income how they wish and what they feel suits them best, and it's very easy to snark at how someone else chooses to do so.  BTW, I chose these amounts for a reason. In NZ, this is about the price difference per month (maybe even less) between a regular connection and a gigabit connection. And the regular connection only has 10 Mbps upload. Intermediate options with faster uploads have largely disappeared or are not cost effective for residential connections. The difference between uploading 100GB or even 10GB on a 10 Mbps vs 400 Mbps is fairly stark. (More realistically you'll maybe top out at 100 Mbps but it's still fairly stark.) Especially since many routers lack decent QoS so it's quite easy for an upload to saturate the the upstream causing the whole internet to become slow due to problems sending ACKs. In fact, if streaming on Twitch or whatever is your thing, 10Mbps is a little low even for  streaming at 1080p60 if you aren't the only one who uses the internet connection.  Since games were mention, it is true that many games nowadays can be 50 GB or more downloads. On a 100 Mbps you're talking maybe a couple of hours to download that, especially on a shared connect. On a Gbps, you may be able to get in in 20 minutes. (These numbers are very rough since your download probably won't saturate your connection all the time especially on the gigabit one.) That has after all been one of the promise of cloud computing, you don't have to worry that it isn't stored locally. When you only have to wait 10-20 minutes to play your game, the thought 'maybe I should download this since I may want to play it in the future' is likely to arise a lot less than when you may need to wait 2 hours.  Nil Einne (talk) 06:38, 2 May 2020 (UTC)
 * Yeah 10 Mbps could be too low on 1080p but 100 Mbps is well enough and probably already causing pointless greenhouse gas emissions. Downloading a 50 GB game (which there aren't that many of) takes roughly an hour on a 100 Mbps conn. Most people download less than 1 TB a month. That's roughly a day of continuous downloading at 100 Mbps. Maybe a few days a month there are situations where you find that something is so large that you see the benefit of 1 Gbps but on the whole I can think of absolutely nothing that couldn't realistically wait that hour for 90% of high speed internet users, including me. People are stuck on the inconvenience treadmill. I remember downloading 10+ MB video game mods every day on dial-up. Now that's waiting. 89.172.65.59 (talk) 15:41, 2 May 2020 (UTC)
 * Sorry I meant mb and fixed previous texts. Also When I said "Same measurement across the board" I was saying that the b from mb at both the cellphone test and the pc speedtest are the same b.2804:7F2:590:9A24:C859:2050:493C:3F0D (talk) 04:15, 1 May 2020 (UTC)
 * First off, please use capital "M" for megabits. This is to avoid misunderstandings like your gigabit speeds, etc.
 * This is a high-level benchmark with many low-level factors that could affect it. Your choice of cabling, the hardware in the access point, the TCP/IP configuration and stack of the client OS, WiFi radio channel and local interference, all kinds of things could factor into this.
 * The fact is that the Internet is wide and varied. You will not receive a solid 300Mbps to Facebook, Yahoo, YouTube, github, Instagram, and everywhere else; your speed will be limited by Internet-transit factors beyond your control and beyond your ISP's control. Therefore, achieving a high score on your SpeedTest.net app is no guarantor of actual performance. Personally, I would say that 40Mbps is downright fantastic for most use cases.
 * If you are still not satisfied and you truly believe you should be getting more out of your advertised 300Mbps connection, the first place to check is with your ISP. They can suggest configuration tweaks and modifications on your end that might squeeze more speed out of the wireless, or the access point. From here, without knowing your hardware or software configuration, or the specs of the ISP, we can only guess in the dark. Elizium23 (talk) 04:36, 1 May 2020 (UTC)
 * This answer seems fairly offtopic. It sounds like the OP's concern is not with other sites. They want to know why when using speedtest, they get 300Mbps if they bypass their router, but a significantly lower speed then they use their router. This likely has fuckall to do with their ISP and definitely nothing to do with connections to other sides, beyond the fact that perhaps their ISP supplied their router. Note that plenty of ISPs will not provide much support for third party routers which could easily be the case here considering the 'modem' apparently supports Wi-fi routing, so is probably a router of some sort. If your connection direct to the 'modem' is fine as it apparently is for the OP, there's a good chance at best they will tell you 'we recommend X routers', we can't help you with problems you have with that router you purchased, try contacting their tech support. And many won't even recommend a router to avoid having to provide supports related to them. I see no reasons things would be particularly different in Brazil. If anything I expect the chance the ISP supplied the router to be even lower. It may be true there's ultimately no point worrying about it since they will often not get close to 300 Mbps anyway, but while this could be briefly mentioned, it doesn't mean the OP's main question should be ignored. Nil Einne (talk) 06:16, 2 May 2020 (UTC)
 * The answer is wrong because clearly this is a router problem but the gist is right, there are very few sites that will suffer a 300 Mbps+ user at full speed. In all of OP's conditions the speed is high enough to stream even 4K. Even if he gets all conditions up to 300 Mbps he's not going to see improvements in real Internet use. 89.172.65.59 (talk) 15:41, 2 May 2020 (UTC)
 * I presume by "wireless" you mean Wi-Fi. Different Wi-Fi versions have different maximum speeds. 802.11g, which is probably the most widely-deployed, maxes out at 54 megabits/s (without proprietary vendor extensions). Sounds like that might be what you're using. 802.11n and 802.11ac have faster maximum speeds, but access point and device both need to support it. Also those are maximum theoretical speeds; they will be generally lower in real-world usage due to interference, encryption overhead, and bandwidth being shared if multiple devices are transmitting at the same time. --47.146.63.87 (talk) 04:22, 2 May 2020 (UTC)
 * We need more info on your router and both the wired and wireless connection to it. Does your router even have a gigabit ethernet port? Some crappy routers even made in the past 5 years or so only have fast ethernet ports. As 47 mentioned, as for Wi-fi, if your router only supports 802.11g for example or it only supports 2.4ghz then your results may not be so surprising. Also crappy routers may not be able to handle routing at your internet connections line speed. This is especially the case with TCP connections. As per my above comment, this is something you come across a lot with gigabit connections but depending on your router, it could be the case for significantly lower speeds.

Comprehensive Geographically-Specific Chronology
I've searched for a long time for a chronology that lists every single event in history, with corresponding GPS coordinates. How do we create this? Here's an example:

1941-12-07 | 18:18:31 Coordinated Universal Time (UTC) | 1941-12-07 07:48:31 Hawaiian Time (UTC-10.5) | GPS Decimal Coordinates: 21.365, -157.95 | The Pearl Harbor naval base is attacked by 353 Imperial Japanese aircraft (including fighters, level and dive bombers, and torpedo bombers) in two waves, launched from six aircraft carriers.

1941-12-07 | 19:18:00 Coordinated Universal Time (UTC) | 1941-12-08 04:18:00 Japan Standard Time (UTC+9) | GPS Decimal Coodinates: 35.672448, 139.757570 | Via the Board of Information of The Japan Times, Japan announces a declaration of war on the United States, but the declaration was not delivered until the following day.

...

1942-02-01 | Requested Edit Coordinated Universal Time (UTC) | Requested Edit Kansu-Szechwan Time (UTC+7) | GPS Decimal Coordinates: 36.618638, 109.467266 | Mao Zedong makes a speech on "Reform in Learning, the Party and Literature", starting the Yan'an Rectification Movement in the Communist Party of China.

This would list everything on one page chronologically from beginning of recorded history up to present day. Thank you!Mtsuzuki (talk) 21:26, 1 May 2020 (UTC)
