Network issues can be frustratingly difficult to troubleshoot, especially if they're intermittent.Sometimes it is a hardware problem, sometimes it is the layout of your home, and yet other times, it comes down to a software issue.If you're experiencing random issues with your Wi-Fi connection, this is a setting you should double-check.
MU-MIMO is supposed to make your Wi-Fi better What does MU-MIMO do? Imagine how annoying it would be if doomscrolling on TikTok was laggy because your router was too busy chatting with your light bulbs to stream video to you.That is the problem MU-MIMO (Multi-User, Multiple Input, Multiple Output) is designed to solve.As the name suggests, MU-MIMO was originally designed to allow your router to send data to multiple devices simultaneously, and a subsequent update with Wi-Fi 6 allowed it to receive information simultaneously too.
Previously, routers had to communicate with connected Wi-Fi devices one at a time.They were able to switch between devices quickly enough that it is usually imperceptible, but when you actually start benchmarking Wi-Fi performance, the difference can be noticeable.Quiz 8 Questions · Test Your KnowledgeHome networking & Wi-FiThink you know your routers from your repeaters — put your home networking know-how to the ultimate test.Wi-FiRoutersSecurityHardwareProtocolsBegin 01 / 8Wi-FiWhat does the '5 GHz' band in Wi-Fi offer compared to the '2.4 GHz' band?ALonger range but slower speedsBFaster speeds but shorter rangeCBetter wall penetration and faster speedsDLower interference but identical speedsThat's right! The 5 GHz band delivers faster data rates but loses signal strength more quickly over distance and through walls.
It's ideal for devices close to the router that need maximum throughput, like streaming 4K video.Not quite — the 5 GHz band actually offers faster speeds at the cost of range.The 2.4 GHz band travels farther and penetrates obstacles better, which is why smart home devices and older gadgets often prefer it.Continue 02 / 8ProtocolsWhich Wi-Fi standard, introduced in 2021, is also known as Wi-Fi 6E and extends into a new frequency band?A802.11acB802.11axC802.11beD802.11nCorrect! 802.11ax is the technical name for Wi-Fi 6 and Wi-Fi 6E.The 'E' variant extends the standard into the 6 GHz band, offering a massive swath of new, less-congested spectrum for faster and more reliable connections.The answer is 802.11ax — that's Wi-Fi 6 and Wi-Fi 6E.
Wi-Fi 6E adds support for the 6 GHz band, giving it far less congestion than the crowded 2.4 GHz and 5 GHz bands.802.11be is actually the upcoming Wi-Fi 7 standard.Continue 03 / 8RoutersWhat is the default IP address most commonly used to access a home router's admin interface?A192.168.0.1 or 192.168.1.1B10.0.0.1 or 172.16.0.1C255.255.255.0 or 255.0.0.0D127.0.0.1 or localhostSpot on! The vast majority of consumer routers use either 192.168.0.1 or 192.168.1.1 as the default gateway address.Typing either into your browser's address bar will bring up the router's login page — just make sure you've changed the default password!The correct answer is 192.168.0.1 or 192.168.1.1.
These are the most common default gateway addresses for home routers.The 255.x.x.x addresses are subnet masks, and 127.0.0.1 is your own machine's loopback address, not a router.Continue 04 / 8SecurityWhich Wi-Fi security protocol is considered most secure for home networks as of 2024?AWEP (Wired Equivalent Privacy)BWPA (Wi-Fi Protected Access)CWPA2 with TKIPDWPA3 (Wi-Fi Protected Access 3)Excellent! WPA3 is the latest and most robust Wi-Fi security protocol, introduced in 2018.It uses Simultaneous Authentication of Equals (SAE) to replace the older Pre-Shared Key handshake, making it far more resistant to brute-force attacks.The answer is WPA3.
WEP is completely broken and should never be used, WPA is outdated, and WPA2 with TKIP has known vulnerabilities.WPA3 offers the strongest protection, and if your router supports it, you should enable it right away.Continue 05 / 8HardwareWhat is the primary difference between a mesh Wi-Fi system and a traditional Wi-Fi range extender?AMesh systems only work with fiber internet connectionsBRange extenders create a seamless single network while mesh systems create separate SSIDsCMesh nodes communicate with each other to form one seamless network, while extenders create a separate networkDMesh systems are always wired, while extenders are always wirelessExactly right! Mesh systems use multiple nodes that talk to each other intelligently, handing off your device seamlessly as you move around your home under one SSID.Traditional range extenders typically broadcast a separate network and can cut bandwidth in half as they relay the signal.The correct answer is that mesh nodes form one intelligent, seamless network.
Range extenders are actually the ones that often create separate SSIDs (like 'MyNetwork_EXT') and can significantly reduce speeds.Mesh systems are far superior for large homes with many devices.Continue 06 / 8ProtocolsWhat does DHCP stand for, and what is its main function on a home network?ADynamic Host Configuration Protocol — it automatically assigns IP addresses to devicesBDirect Hardware Control Protocol — it manages router firmware updatesCDistributed Hosting and Caching Protocol — it speeds up web browsingDDynamic Hypertext Communication Protocol — it secures data transmissionsPerfect! DHCP (Dynamic Host Configuration Protocol) is the unsung hero of home networking.Every time a device joins your network, your router's DHCP server automatically hands it a unique IP address, subnet mask, and gateway info so it can communicate without manual configuration.DHCP stands for Dynamic Host Configuration Protocol, and its job is to automatically assign IP addresses to devices on your network.
Without it, you'd have to manually configure a unique IP address on every single phone, laptop, and smart device — a tedious nightmare!Continue 07 / 8RoutersWhat is 'QoS' (Quality of Service) used for in a home router?AEncrypting all traffic leaving the routerBPrioritizing certain types of network traffic over othersCAutomatically switching between 2.4 GHz and 5 GHz bandsDBlocking malicious websites using a DNS filterThat's correct! QoS lets you tell your router which traffic gets priority.For example, you can prioritize video calls or gaming over a family member's file download, ensuring your Zoom meeting doesn't freeze just because someone is downloading a large update.QoS — Quality of Service — is actually about traffic prioritization.By tagging certain data types (like VoIP calls or gaming packets) as high priority, your router ensures latency-sensitive applications get bandwidth first, even when the network is congested.Continue 08 / 8HardwareWhat does the 'WAN' port on a home router connect to?AOther computers in your home network via EthernetBA wireless access point for extending Wi-Fi coverageCYour modem or ISP-provided gateway to the internetDA network-attached storage (NAS) deviceCorrect! WAN stands for Wide Area Network, and the WAN port is where your router connects to the outside world — typically to your cable modem, DSL modem, or ISP gateway.
The LAN ports on the other side connect to devices inside your home network.The WAN (Wide Area Network) port connects your router to your ISP's modem or gateway — essentially your entry point to the internet.The LAN (Local Area Network) ports are for connecting devices inside your home.Mixing them up can cause your network to not function at all!See My Score Challenge CompleteYour Score/ 8Thanks for playing!Try Again MU-MIMO is especially important now, when there are more Wi-Fi enabled devices than ever before.
Quickly communicating with one device at a time was tolerable when there were only four phones and a laptop connected to the network.Today, there can be dozens of devices attached to a home Wi-Fi network, including smart appliances, TVs, laptops, phones, tablets, light bulbs, smart outlets, and more.Smart bulbs actually aren't all that demanding on your network.
Streaming video, gaming, downloading updates, and other demanding tasks are really where MU-MIMO shines.MU-MIMO can sometimes cause problems MU-MIMO was first implemented in 2015, and devices older than that are to fall back to using the older protocol.Unfortunately, buggy or poor firmware can occasionally result in nondescript connectivity errors, like random disconnects or lag.

If it is, you have some options.Related This free firmware made my old router useful again (and safer) Give old hardware a new lease on life and a new purpose.Posts 2 By Nick Lewis Disable MU-MIMO on your Wi-Fi network Log into your router and shut it off To disable MU-MIMO, log into your router through your browser.
In most cases, you can do that by typing 192.168.0.1 or 10.0.0.1 in your browser's address bar.If neither of those work, run ipconfig /all in the Terminal on Windows or ip a on Linux, then look for "Default Gateway" in the output.That is the IP address of your router.
Once you've logged into your router, look for a search button and type mu-mimo in the search bar—it is faster than manually looking through the settings.If your router's software doesn't have a search button, look through the wireless settings instead.You may need to dig a bit.
I've seen this setting available in the general wireless settings on some routers and buried in the advanced settings on others.Wherever you find it, click the drop-down menu and set MU-MIMO to Disabled.In my case, I can disable MU-MIMO without disabling OFDMA; your options may be different depending on your router.
Your router probably won't need to restart to disable MU-MIMO, but if it does, make sure to save whatever you're working on first.Fixing MU-MIMO problems Updating all newer devices may help Fortunately, MU-MIMO problems with newer devices are usually not because of a hardware problem, they're caused by buggy firmware.That means that updating your router or device—be it a phone, TV, or something else—could fix the issue.
Always start there first.It has the best chance of working and only takes a few minutes.Getting an older device working with MU-MIMO If the device is just too old to work with MU-MIMO and you don't want to leave the feature disabled on your router, you could try attaching a USB Wi-Fi adapter to it.
Most PCs manufactured between 2010 and 2015 will be able to use it, you just need to be sure that the Wi-Fi adapter's drivers will work.Your operating system is going to matter a lot there.ASUS WiFi 6 AX1800 USB WiFi Adapter (USB-AX56) This handy little USB dongle features Wi-Fi 6 and a dual-use design.
You can plug it directly into your PC or laptop or use the included tether for better reception.See at Amazon Expand Collapse If your PC is running Windows 10, you'll probably be able to buy a Wi-Fi adapter that is specifically stated to work with it.Additionally, most Wi-Fi adapters that are compatible with Windows 11 will also be compatible with Windows 10, even if they don't explicitly state it.
Linux is a different story.Driver support for USB Wi-Fi adapters is *very* hit-and-miss on Linux, so be sure to double-check the documentation.Subscribe for clear Wi-Fi fixes and MU-MIMO tips Join the newsletter for practical Wi-Fi troubleshooting, clear firmware and device-compatibility guidance, and step-by-step explanations of features like MU-MIMO.
