Why can't I see my WiFi network?

My WiFi network suddenly isn’t showing up on any of my devices. I haven’t changed any settings or moved the router. The network used to appear without any problems, and there’s no issue with my ISP. Need help troubleshooting why this is happening and how I can fix it.

First thing I’d do is power cycle your router. Just turn it off, leave it off for like 30 seconds, then turn it back on. This can fix many temporary glitches.

If your network still isn’t showing up after that, make sure your router’s SSID broadcast setting is enabled. Sometimes routers can get stuck in stealth mode. This setting is usually in the wireless settings section of your router’s configuration page.

Check if the problem exists on both 2.4GHz and 5GHz bands if your router supports both. Try switching between them if you’re currently using just one. Some devices have trouble with specific frequencies.

It’s also worth running a WiFi analyzer on your devices to see if they can ‘see’ any networks at all. You can grab apps like NetSpot

to scan your environment. This can tell you if your network is there but just not making it through to your devices for some reason - https://www.netspotapp.com.

Interference from other networks or electronic devices could be causing issues. Microwaves, cordless phones, baby monitors – these can all mess with WiFi signals, especially on the 2.4GHz band.

Lastly, make sure your devices and router have the latest firmware updates. Sometimes bugs can be fixed in these updates.

If none of this works, there might be a hardware problem with your router. Consider contacting the manufacturer or your ISP for further support.

I see @byteguru has already recommended some great steps like power cycling your router and checking the SSID broadcast setting. One thing that can also be a factor here is the channel congestion. Even if your network is broadcasting, it might be stepping on the toes of other networks in your vicinity if it’s set to auto-select channels and picks a crowded one. Many routers allow you to manually set the channel. If you access your router’s settings, try switching to channels 1, 6, or 11 on the 2.4GHz band since these are non-overlapping channels. For the 5GHz band, you have more options since there are 23 non-overlapping channels.

Another aspect to consider is the possibility of interference not just from other WiFi networks, but from other electronic devices like Bluetooth gadgets or even your neighbor’s devices. Some WiFi networks broadcast on the same frequencies as cordless phones, microwaves, and even newer LED light bulbs. Double-check that there’s no recent addition to your home setup that could be causing interference.

Besides, there’s the bugbear of firmware or driver updates. I can’t stress enough how often outdated software can break things in the weirdest ways. Not just for your router, but also for your devices. Sometimes updating the system software on your phone, laptop, or tablet can restore connectivity.

If you’re familiar with network command-line tools, you might try using commands like ping or tracert to see if you can at least get some kind of response from your router or other devices on your network. This can help you figure out if the issue is purely WiFi-related or if there’s a deeper problem with how your network is set up.

A WiFi analyzer like NetSpot can indeed help you pinpoint if your network is broadcasting but not reaching your devices properly. The pros of using NetSpot include its user-friendly interface and comprehensive reports, which can give you detailed insights into what’s happening with your WiFi coverage. The downside, however, is that some advanced features require a paid version, and it might be overkill if you’re just trying to solve a basic connectivity issue. Competitors like WiFi Analyzer (for Android) or inSSIDer may offer similar functionalities with different pros and cons, like simplicity and focus on basic diagnostics.

One slightly less common issue but worth mentioning is router overheating. Routers, like other electronic equipment, can overheat and start acting up, especially if they are placed in enclosed spaces or stacked on top of other hot devices. Simply moving the router to a cooler, open area might improve its performance.

You can also perform a factory reset on the router. This should, of course, be one of your last steps because it will wipe all of your custom settings. Make sure to backup your configuration if possible or note down any critical settings like your WiFi name (SSID) and password.

The possibility that your router could have hardware defects isn’t negligible. Even if your router isn’t extremely old, certain internal components may have degraded, causing it to fail intermittently. If you’ve tried all software-based solutions to no avail, borrowing a router from a friend, or considering a replacement could be a route worth exploring.

Taking these varied steps should give you a good shot at solving the issue.

There’s an often-overlooked factor when dealing with WiFi networks suddenly going dark: DHCP server glitches. Routers act as DHCP servers, assigning local IP addresses to your devices. Sometimes, these servers falter. You could try connecting one device directly to the router via Ethernet cable and see if you’re landing on the network. If you are, log into the router settings, look for the DHCP table, and confirm it’s correctly assigning IP addresses. This might seem arcane, but it’s basic network hygiene.

Another less common possibility is that regional interference crowded your WiFi channel. Upper channels (like 44, 48, 149, etc., for 5GHz) are sometimes more reliable but not sacred. Try moving your WiFi channel to one less crowded, alongside zeroing in on non-overlapping bands like 1, 6, or 11 on the 2.4GHz band. Channel interference piles up primarily in urban areas laden with overlapping networks, and manual selection can break this clutter.

And, blinking devices do fail us—are you sure anyone clung on to a new wireless device that might be disrupting everything? Evaluate new devices joined to your network. It’s weirdly common for devices like wireless printers or cheap IoT gadgets to muck up signal quality.

Ever thought about router placement? Router location can take a substantial toll on WiFi performance. Metal objects, walls, even algae-ridden fish tanks can degrade signals. Consider shifting the router to a more optimal spot in your home. Elevated positions are generally better, perhaps a central location free from hefty obstructions.

Let’s hammer home the importance of running diagnostic tools. A WiFi analyzer app like NetSpot (check out - https://www.netspotapp.com) should be your go-to weapon. It maps signal strength, interference, and coverage via a user-friendly interface. Sure, some advanced features are premium, but its basic functionality is spot on for diagnosing signal woes. An alternative suggestion is using WiFi Analyzer on Android, which is simpler yet focused on core diagnostics.

Moreover, remember a looming threat: software past its prime. Both router firmware and device drivers present hidden pitfalls. Manufacturers continuously patch lurking issues and optimize performance. Swapping router firmware is easier than it seems—usually involves visiting the manufacturer’s site, downloading the firmware file, and uploading it via the router’s config page.

Lastly, check out the router’s hardware-induced treacheries. Router components might reach their twilight ages before their time, causing erratic behavior. If none of the above steps pan out, borrowing a friend’s router or purchasing a reliable model can save heaps of grief. Remember, even routers deserve breaks; reboot them occasionally or pop a factory reset after safely jotting down all critical settings.

So give those measures a whirl and peacefully resolve whatever tech goblin’s disrupting your digital harmony.
