Your internet can be slow for many reasons. Your internet plan may be too slow for your needs, your modem or router may be out of date, your router may be on the fritz, or you might have too many people using your Wi-Fi at the same time. We can help you identify where the problem is and how to fix it.
You can improve your internet speed by upgrading to a faster plan, updating your equipment, or taking simpler measures like closing out apps and browser windows. We can walk you through 10 steps to improve your internet speed in just 15 minutes.
The fastest internet providers are Google Fiber, Verizon Fios, Xfinity, Metronet, and Cox. All of those internet providers offer fiber or cable internet plans with gigabit speeds. See our report on the Fastest Internet Providers.
If you see inconsistent results, there might be a bottleneck on your end. You can troubleshoot poor internet speeds with our guide on how to fix slow internet. But your internet connection may just be slow either from your plan or your internet type.
The time (measured in milliseconds) it takes for a signal to travel from your device to an internet server and back. Lower latency means your connection has a better response time for activities like gaming and livestreams.
There are several factors that determine speed when above about 300Mbps. I chased the same issue for days and found the bigest issue is if the test site is using IPv4 or IPv6. I found my router can only acheive about 350Mbps using IPv6, but can get 950Mbps using IPv4. The older Xfinity speed test had an option to set which IP version to use, but defaulted to IPv6. I have since switched to DSLreports speed test which allows selection of several test settings in the advanced section. To get the full 1Gbps I would use IPv4 and search for a very fast router. Most consumer routers will not achieve 1G using IPv6. I just bought a commercial router but I haven't put it online yet as runs Linux and uses command line syntax for settings. This class of router usually does not include WiFi so you will need a WiFi router as well. As stated above, everything must be wired with good ethernet cables.
I see the new Xfinity speed test now allows selection of test server and IP version. Another thing I found was if your computer is attached to your network through switche(s), the economical swithes will slow your speed as well. I plugged my computer directly into my modem to get full spped when I upgraded to 1G. I bought a managed, full duplex 16 port switch to replace my cascaded $15 5 port switches. Now everything is home run directly to the 16 port switch. This also made a huge different during my 1G testing.
Just to add a little more info to this thread. I have 1Gb service. I use a DOCIS 3.1 modem and an Orbi mesh router system. My desktop PC is on the wire. Modem -> Router-> Switch -> Desktop. Up until about a month ago, I was seeing between 970Mbs and 1.0 Gb on the speed test. On WiFi (laptop) getting about 550 Mbs, probably due to back chanenl communication over the mesh system, etc. Very acceptable.
About a month or two, ago, the speed test dropped to between 490Mbs and 510Mbs (on the wire) and has remained there. No other changes to my network have been made. It seems quite likely to me that Comcast has re-distributed bandwidth and/or throttled speed, perhaps due to increased demand during the lockdow when more folks are not in the office (i.e. they are online, at home).
I get the 1 gig speeds with no problem with the Xb6 gateway, I am curious if anyone checked the settings on their network cards, configured wrong and you won't get the 1 gig speeds, also are you using a Dell computer? They install a program called smartbyte that throttles your download speeds to about half of what is expected, I also experimented with the different router settings that I was able to change, some say they are grayed out, but mine aren't and I was able to dial in optimum speeds, just my thoughts
It is supposed that the Orbi Ac2200 handles speed unitl 833 Mbps when connected to 5Ghz so why I can;t get more than 300's Mbps?. I am thinking to get the Orbi 6, but first I want to be sure the problems is the AC2200.
A lot depends on settings, interference, device's capabilities, etc. If a laptop, (I have one), has a NIC that only supports 2.4Ghz 150Mbps, that is all you are going to get out of that device. Most of my wireless devices connect between 150 and 475Mbps. Most WIFI6 devices connect between 400 and 850Mbps. The further away from the router or satellite I am, the slower the speed.
833 Mbps is the theoretical maximum for AC but realistic networking conditions, encryption, etc. make real world wireless speeds much, much less. Even AX real world speeds (seen by only AX-compatible devices like the iPhone 11 Pro) don't usually reach 833 Mbps.
Wi-Fi is a half-duplex medium. Wired is a full-duplex medium. If wireless is giving you close to half your wired speed, your WIFI is operating at near optimum performance. Wi-Fi is also a shared medium therefore it behaves as a hub. Devices wanting to transmit have to request and gain access before being able to transmit, creating overhead and slowing speed.
Regarding speed tests: If you use an internet speed test to measure the speed of your wi-fi, you will not get an accurate result, as there are many hub hops during the test, that could be slowing the test results. Also WIFI conditions along the hub hops, change often.
It is more accurate to measure your speed using the internal Orbi speed test for connection speed and use a porformance tester to test the speed between your wireless device and a device connected to your internal network.
Thanks!, so for what I am understanding if the wifi speed is affected by the own wifi protocols and the capacity of each device, it is telling me as well that changing from AC2200 system to the new Orbi WiFi 6 mesh won;t do much for me either unless I contract a higher speed internet?. For 1 Gb speed I have now then I should expect half. The actual speed I normally read connected by wire to the modem is somewhere between 600-800 Mbp, so 300-400 Mbp is most probably the best I can do independent of the mesh system? I mean, if I won't be able to get more than 500 Mbp with a 1 Gbp conection it doesn't make sense to expend $500 in a new system for probably 100 Mbp more.
I have Xfinity Comcast cable internet service. I am provisioned 1000 Mbps download / 20 Mbps Up.
When I run speedtest either from Xfinity or speedtest.net, the test says I roughly get around 300MB download give or take.
I had Xfinity come out because I didnt think I was getting the 1000 MBPS service. They tested from the Coaxial cable prior to the cable modem a 1000 MBPS service with their meter equipment. They tested coming from any of the LAN ports with their meter equipment and it shows getting 1000 MBPS service. But for some reason when my ethernet cable is plugged into my PC or laptop from any of the cable modem LAN ports, I am getting approx 300 MB. Xfinity even hooked up their laptop into one of the LAN ports and they also saw an approx 300 MB download speed too.
Is the SBG8300 throttling down the internet speed when using the LAN Ports? When I use the WIFI 2.5 and 5, my speeds are what they should be. The 5 GHZ is showing around approx 500 MB download speed. This should never be faster than my hardwired computer setup.
I appreciate any assistance.
Thanks for the detailed explanation since you have done all possible trouble shooting and done checking with your internet service provider we would suggest you to reach out to arris technical support for further assistance check on arris.com/consumersupport
I am using our corporate internet connection which is 1gb/sec. When our sysadmin plugs in his laptop to my ethernet port, he is getting about 800mbps up/down... But my MBP will only get about 375up and 478down.
You might find for example if you are copying files to a local server that Mac is slow due to using wrong protocol. Even for internet testing via one of the standard sites might not give you correct reading in some situations.
I would not think the difference would be major. USB is known to be very CPU hungry.. and gigabit connection over USB 3 adapters might not have drivers for Mac.. remember all these adapters and dongles depend on drivers.
Assuming that the AirPort Express is connected using Ethernet.........the Express has only 100 Mbps Ethernet ports, so the speed of device(s) connected to the Express is never going to exceed 100 Mbps.
Fact is the vast majority of domestic routers cannot handle gigabit.. so this is not unique to the AE.. it is just unfortunate that Apple wrote the firmware themselves and removed the hardware acceleration.
