How to troubleshoot internet connection problems

The most common issue is that your app is unable to connect to your computer. There are many different things that can cause this problem, which is out of our control. Please try these suggestions before contacting us.

In the app, remove all saved servers and re-add them. This should solve any issues where your computer's network address has changed.

Check your WiFi network. Make sure your computer and smartphone/device are connected to the same network. It doesn't matter if your computer has wired internet as long as they are connected to the same box!

Update to the latest version. Make sure both your app and server are updated to the latest versions. Follow our Update tutorial for more details on how to update.

Check your firewall. If you are using Windows try our Windows Firewall tutorial to make sure your firewall is configured correctly. If you are using other security solutions, make sure ports 9512 TCP and UDP are allowed, and port 9511 UDP (for automatic server discovery).
If you are using Mac try our Security & Privacy tutorial to setup the firewall.

Perform a ping test. There might be something else blocking the communication between your device and computer. Follow our Ping Test tutorial to check the connection.

If your mouse isn't working (or if it's sluggish/jittery), you can try reinstalling the server without the driver. Have a look at this tutorial.

If all fails. Restart your computer. Also try reinstalling Unified Remote (app and server).

If you find that your internet connection, in Windows11, Windows 10, Windows 8 or Windows 7, has suddenly stopped working or that you are facing certain Network and Internet connectivity problems, here are a few troubleshooting steps you may want to try.

Fix Network & Internet connection problems

  1. Renew IP address
  2. Flush DNS cache
  3. Use Network & Internet Diagnostic & Repair Tool
  4. Enable or Disable IPv6
  5. Reset Winsock
  6. Reset TCP/IP,
  7. Reset Hosts file,
  8. Reset Windows Firewall settings to default,
  9. Reset your browser
  10. Run Network Reset.

These suggestions are followed by other fixes too. Take a look at them!

1] IPConfig is a tool built into Windows, that displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol DHCP and Domain Name System DNS settings. You can access this tool via the command line. If you have a bad IP address, then renewing your IP address this way may help solve your internet problems.

Type cmd in start search and press Ctrl-Shift-Enter. If you wish, just out of curiosity, you may type ipconfig and hit Enter, to view the status of the computer’s Internet Protocol or IP address.

Type ipconfig /release to let go of the current IP address.

Next, type ipconfig /renew to obtain a new IP address.

If you get an error message when you Run the “Ipconfig /Renew” command see KB810606.

If you recurrently face this problem, then you can have it renewed on every start-up, by creating the following .bat file and placing it in your startup folder.

Open Notepad and type:

Save it as, say, iprenew.bat file.

2] Frequently, internet connection problems can also be traced to a corrupted DNS cache. Resetting or Flushing this cache is an easy fix to many of these problems. This is how you can flush Windows DNS cache in Windows 11/10, Windows 8/7 or Windows Vista.

Start > All Programs > Accessories > Command Prompt. Right-click on it and ‘Run As Administrator’. Type the following and hit enter:

You should be able to see a confirmation dialog window:

Windows IP Configuration. Successfully flushed the DNS Resolver Cache.

Next, type ipconfig /registerdns and hit Enter.

This registers any DNS records that you or some programs may have recorded in your Hosts file.

Just in case you are interested, to view the complete syntax for this command type ipconfig /help and hit Enter!

3] The Network & Internet Diagnostic & Repair Tool in Windows 11/10/8/7/Vista will help you identify the potential issues preventing network connectivity, and it automatically takes appropriate steps toward correcting them. If a computer on the network loses Internet connectivity, you can graphically see which connection is down and then use Network Diagnostics to help determine the cause of the problem and find possible solutions.

There are few things in life as frustrating as an "Address Not Found" message in your Web browser. Timed-out connections, a little red X in your network connection icon, or an "Internet Explorer cannot display the Web page" error screen all add up to the same dismal problem — something’s wrong with your Internet connection.

Finding and fixing the problem is never easy, mainly because there are so many places where something can go wrong. We’re going to walk you through five relatively easy steps that will solve the majority of broadband Internet connection problems, no matter what kind of Internet service you use. We’ll have you up and running, reading celebrity gossip and updating your Facebook status in no time.

5: Check the Wires

It may seem obvious, but one of the easiest troubleshooting steps you can take yourself is to check all the cables and connections involved in your Internet connection. This is true no matter what kind of connection you have. Even if you’re sure nothing has changed, it only takes a minute to make sure.

Start where your Internet service enters your house. This might be your cable company’s line drop, a satellite dish antenna or a phone line. Make sure the cable is connected securely, and any cabling that runs outside the house hasn’t been damaged by weather or chewed on by birds, bugs or squirrels. Just be careful if there are any electrical lines around — and if you see damaged lines of any kind, don’t touch them, just call the cable or phone company.

Next, follow the cables through your house, checking connections at every appropriate point. If you use a router, check those connections, too, and make sure the correct cable is going to the correct place. If your router feeds several different computers or gaming systems, it can get confusing to keep track of which cable goes where.

If the cabling and connections seem OK, the next step is to power cycle your modem.

4: Power Cycling

Power cycling might sound exciting, but it just means turning your modem off, waiting a few seconds, then turning it on again. This works regardless of your connection type, whether you get your Internet via cable, DSL or satellite. The easiest way to turn it off is to disconnect the power cord where it plugs into the modem itself (they don’t always have on/off switches, but if yours does, that should work, too). Wait about 30 seconds, and then plug it in again. Sometimes, that’s all it takes. Once the modem has cycled through its usual boot-up sequence, you may find your connection works again.

If this doesn’t do the trick, a more elaborate power cycling sequence might. You’ll have to turn off every device on your network, then power them on again in a particular order.

First, shut off your computer, then unplug the power cords from your modem, router, access point and hub.When you turn things on again, follow the signal from the modem toward the computer. In other words, power up the modem first, then power up your router or hub, then turn on your computer last. As you turn on each device, wait for it go through its boot-up sequence before powering up the next device in line. You can determine the status by watching the lights on the device itself.

Still no connection? If you use a satellite Internet service, we’ll troubleshoot your unique problems in the next section.

3: Weathering Storms with Satellite Internet Connections

If you access the Internet with a satellite service, you have your own set of issues to deal with. The first potential issue is line of sight. Satellite Internet connections use a special two-way dish, and the dish has to be pointed directly at the satellite at a very particular angle. The problems start when anything gets between your antenna and the satellite.

Overgrown greenery, snow and ice or leaves and other debris could be blocking your dish, so you’ll have to get to the dish to clear it off. This can be especially difficult if it’s mounted on the roof.

Odd as it may seem, weather hundreds of miles away can also affect your satellite connection. Because the satellite is over the equator, your dish points south (that is, if you’re in the Northern Hemisphere). The farther you are from the equator, the less direct the line of sight is. Your dish has to send and receive signals through a long stretch of atmosphere to the south, so southerly storms many miles away can still cause interference.

If there’s nothing in the way, and the weather is clear from your roof all the way to Guatemala, your dish might be misaligned. If it isn’t pointing in the proper direction, your connection will fail. Satellite dish antennas require much more precise adjustment than TV dish antennas do – it’s probably a good idea to call your Internet service provider for help, rather than trying to adjust it yourself.

And on top of that, the problem might be beyond everyone’s control. Sunspots are massive flares on the surface of the sun that send intense blasts of energy at the Earth. That energy can severely disrupt satellite communications.

Next, we’ll diagnose some common wireless problems.

2: Wireless Router Outages

If you use a wireless access point or wireless router to access the Internet with a laptop, then the wireless connection might be the cause of your problem. You may have to use a wired connection to your network until the wireless problem is solved. You’ll also want to have a copy of your wireless access point or router’s user manual nearby.

There are two main potential issues with wireless connections: configuration problems and security problems. Consult the user manual to see how to access the wireless device — this is usually done by typing the device’s IP address into a Web browser. From there, you’ll need to check the manual to find the proper settings. You’ll probably have to call your Internet service provider (ISP) for assistance, because the necessary configuration will vary tremendously depending on the type of network you have and the type of connection provided by your ISP.

The wireless device’s security settings could also be causing problems. You can access these settings the same way you accessed the configuration. If you have a wireless security protocol enabled, you won’t be able to access the wireless device without using the proper password. You can set and reset the password the same way you can change the other settings.

If none of these steps have solved your connection problem, there are still a few last-ditch efforts you can attempt.

You may experience connection problems on your PS4 from time to time. Sometimes, the issue may be coming from the console itself while at other times, it’s entirely outside of it. In most cases, simple troubleshooting steps like checking network cables or restarting the console fix connection woes but at other times, the cause is deeper. This guide will show you the possible solutions that you can try if you have a connection problem when gaming on your PS4.

Causes of PS4 internet connection issues

There are a number of possible factors that may cause connection problems on your PS4. Let’s discuss each of them below.

PlayStation Network Services are down.

If you’re having trouble connecting to an online game, like when you can’t join a multiplayer session, or can’t access game servers at all, it’s likely that the issue is with the PlayStation Network servers. At the time of this writing, many PS4 gamers may find that their downloads are slower than normal or delayed because Sony has intentionally slowed down their services as they work with Internet Service Providers in reducing internet traffic. There can be different reasons why there’s PSN servers issue although the common ones include outages or maintenance.

Bugs with home network equipment.

Modems or routers may encounter errors from time to time, which can result to degraded performance or connection problems. You may need to work with your ISP or replace your network equipment if your home internet connection won’t improve at all.

Network cable is bad.

If your PS4 uses wired connection, one of the possible causes of connection issues can be the ethernet cable. You want to make sure that you check the network cables in troubleshooting your issue.

ISP-related problem.

If you are unable to connect to the Internet on your PS4, one of the factors that you must check is the connection from your ISP. If all your devices can’t connect to the internet at the same time, you may have to contact your ISP for a possible issue from their end.

IP conflict.

A modem or router assigns an Internet Protocol (IP) address to each device that’s connected to it. Sometimes, two devices in a home network may share the same local IP address. This can result to connection problems for the devices affected since only one device can use a local IP at one time.

What to do if your PS4 has connection problems or won’t connect to the internet

Below are the troubleshooting steps that you can do to identify the source of the problem you’re experiencing.

    Do a quick cables check.

If you’re on a wired setup, you want to make sure that you deal with your network cables early in your troubleshooting ladder. Try unplugging the ethernet cable from both the router and PS4 and ensure that both ends are plugged in properly afterwards. If nothing changes, try using a second ethernet cable or use another ethernet port in your router.How to troubleshoot internet connection problems

If you don’t use a wired connection and using a wifi instead, make sure that you troubleshoot for a possible wifi issue on your PS4. These two articles can assist you in this regard:

Another important troubleshooting step to fix any connection issue on your PS4 is to check PlayStation Network services status. The problem you’re having may be caused by a server outage, maintenance, or issue.How to troubleshoot internet connection problems

Make sure that you reboot your PS4 and modem/router. Turn off your PS4, disconnect the power cable from the back and wait for 30 seconds. Do the same for your modem or router. Once the devices have been shut down, turn on the modem or router first but not the PS4. you’ll have to wait until the router has finished starting up fully. Once the lights on your router are stable again, that’s the time that you want to turn on the PS4 and see if the connection problem is gone.How to troubleshoot internet connection problems

If you are connected to your own home network, try to check if other devices are having the same issue your PS4 is experiencing. If there are multiple other devices with the same exact connection problem in your network, there may be an issue with the modem/router, or your internet connection in general. You may have to get help from your ISP after doing a power cycle of your modem or router.How to troubleshoot internet connection problems

If you’re having an issue playing an online game, connecting to an online multiplayer game, or connecting to the PlayStation Network you may have a port problem. The router must allow the following ports to be accessible in for your PS4 to connect to the PlayStation network:
-TCP: 80, 443, 3478, 3479, 3480
-UDP: 3478, 3479
If you are not sure how to check your router if these ports are opened, contact your ISP or consult the documentation that comes with it.How to troubleshoot internet connection problems

Contact PlayStation support

If you are positive that there’s no problem with your router or your ISP, we suggest that you contact Sony’s PlayStation support so they can assist you further in checking a possible network port issue on your console.

HDMI is now the main type of connection used in home theater setups that include HDTVs, video projectors, Blu-ray Disc players, home theater receivers, network media players, and even cable/satellite boxes. One purpose of HDMI is to simplify connecting all your components together by using one cable for both audio and video.

Before frustration sets in, there are some things you can do yourself to remedy the issue.

HDMI Troubleshooting Tips

  1. Check Your HDMI Cable Connections: HDMI connections don’t fit as tight as component or composite video connections and can slip out sometimes if equipment is moved slightly. Please ensure that all HDMI connections are seated firmly and in the correct orientation of their corresponding HDMI ports.
  2. Try a Different Power Up Sequence for Your Components: In other words, if you have a habit of turning on your TV first, then your Blu-ray Disc player, or other HDMI source component, try the reverse power up sequence and see if that works.

Also, if you have a Blu-ray Disc player, or other component, connected through a home theater receiver and then to the TV – try different startup combinations and see if that works. If you find a sequence that works, remember it. Of course, make sure when everything is turned on, and that you have selected the correct input on your TV that the Blu-ray Disc player, or other source component, is connected to.

However, if changing the power up sequence of your TV and connected components doesn’t seem to do the trick, with both the TV and source component on, just try switching to another input on the TV and then switch back to HDMI input and to see if the signal locks in correctly.

  1. Check Your Source Device’s Video Resolution & Refresh Rate Output Setting: If your Blu-ray Disc player or other HDMI source device has a video resolution output setting menu, check to see if it is set to AUTO. If so, reset it to match the native resolution of your TV or video projector (such as 720por 1080p) and see if that provides a more stable result. If your source device has the option for adjusting the refresh rate of the output signal, ensure that your source device is outputting a refresh rate supported by your display (30Hz or 60Hz).
  2. Use the Process of Elimination: If you have a Blu-ray Disc player (or other HDMI source) connected through a home theater receiver to a TV and you still don’t get anything to show up your TV screen regardless of the power up sequence you try, use the process of elimination. Connect the Blu-ray Disc (or other HDMI source) directly to the TV. This bypasses the home theater receiver. See if that does the trick. If so, the home theater receiver, or the HDMI source component/home theater receiver combination is most likely the culprit.

What you can do now is keep the HDMI source connected directly to your TV and then make a separate audio connection from your source device (such as a Blu-ray Disc player) to your home theater receiver. This is not necessarily the most efficient connection method, but you can still use the separate video and audio connection workaround as the best option for the time being, or as a permanent solution if you prefer.

On the other hand, if you find that none of the above solutions work or work consistently – check to see if there are any announced firmware updates for your HDMI source and home theater receiver (or even your TV) that may resolve this issue. Also check to see there have been complaints filed or posted by other users regarding HDMI handshake issues with your components.

Connecting Your PC/Laptop to a TV Using HDMI

With more consumers using their PC or Laptop as a home theater source component, problems can arise when trying to connect an HDMI-equipped PC/Laptop to an HDMI-equipped TV. First, make sure that you go into your PC/Laptop settings and designate HDMI as the default output connection for both video and audio. If you can’t get an image from your laptop to show up on your TV screen, try the following:

  1. Try booting up your PC/Laptop with the HDMI cable connected to a TV that is on.
  2. You can try booting up the PC/Laptop while the TV is off and then turn on the TV.
  3. If the above options don’t work, try booting up the PC/Laptop first, and, with the TV on, connect the HDMI cable to both the PC/Laptop and TV.
  4. Ensure that your PC’s output resolution and refresh rate are supported by your display (1920 x 1080, 60Hz is a good starting point)
  5. Verify your display mode. “Windows Key + ‘P’ key” will cycle through your different display modes. Try duplicate mode to mirror your pc monitor or extended mode to treat your TV as a second display.

Final Take

In the vast majority of cases, you won’t encounter any problems that are the fault of HDMI connections. However, there are instances where you can run into a problem. If you do, don’t panic, before you make any phone calls, or pack everything up and return to the store upset, try the above suggestions. If none of these solutions work, then proceed to contact the J-Tech Digital Support Team. Only after exhausting all of the options you can try yourself should you call a tech or return to the store.
