In some cases, you may see an ADSL Modem troubleshooting message on your system. There can be several reasons for this problem.

  1. Make sure the surge protectors are installed correctly and free from defects.
  2. Turn the modem on and off.
  3. Check the LEDs on your modem. If the Power LED does not turn on when you plug in or turn on the modem, the modem may not be receiving power. Try replacing the power cord first.



This is a basic ADSL troubleshooting guide. Before continuing, you should try to fix the problem that is related to your own network. For more information, see our Guide to Troubleshooting Basic Connectivity Issues.

My ADSL Connection Was Interrupted

If your ADSL connection is not working, you must first try to restart the kit. It sounds like a cliché, but in many cases it can help bring the connection back to life. It is enough to turn off the router for a few seconds and then turn it back on. However, it is always recommended to turn it off for at least a minute before trying it again. Another thing to always try is to disable the microfilter on the telephone wall jack. Microfilters are often made from very cheap components and can fail. For a few pounds, it’s always a good idea to have a few spare parts in the office so you can try out alternatives if the line breaks. Many ISPs include this in their troubleshooting process and ask you to turn it off in As a mandatory step before approving an engineer visit. Also, make sure the cables to the router are not blocked, blocked, twisted, or contain anything.

If the restart didn’t work and you’ve ruled out the possibility of a problem with your network or kit, the only thing you can do is talk to your ISP to log the bug. However, there is some very useful information you can record and share with your ISP to speed up the process for you and for him:

  • Be sure to tell them that you have completely turned off and then turned on the router, and that you have turned off the microfilter.
  • For line status information, refer to your router manual or user manual. All routers have a sync indicator and a PPP session indicator. The sync indicator determines if the router is synchronized with the exchange, while the PPP session indicator indicates whether the ADSL username and password are authenticated on the authentication server of your internet product Aider. Both are required for a successful ADSL connection. Refer to the manual to find out what indicators they represent and what condition they indicate in your situation. This is not an exact science, but if your router is out of sync on the line, there will likely be a line failure when your router is syncronized but unable to negotiate a PPP session. The problem is more of a server problem or a problem with your username or password. If you are filing a bug with the provider, please provide information about the status of the ad so you can identify the problem.
  • If possible, connect an analog phone to the line and watch for noise, problems, dial tone, weak or intermittent dial tone — mostly anything that looks abnormal. A clear dial tone is required for the ADSL connection to function effectively, and you can determine that a bad phone line is causing the problem. If you notice anything unusual, contact your telephone company and ask them to check it remotely. If you cannot find anything suspicious, please reportyour ISP’s support team that you performed this test and found nothing.

My ADSL Connection Is Dropping

Probably the hardest part of troubleshooting an ADSL line and identifying it is when your line is intermittent and out of service at random times of the day. There is no exact science. Ultimately, you should talk to your ISP about this. You can run various tests and adjust many parameters remotely to improve the situation. However, there are some things you can try on your own to fix this problem. Go through this list and try to always tell your ISP what you have tried.

You can find a lot of information on troubleshooting intermittent connections in our guides on basic connection troubleshooting and basic router troubleshooting guides.

  • Always try to give your ADSL router a good power cycle. ADSL routers are electrical devices that typically operate24 hours a day, 365 days a year. They can become old and bulky, and components can fail or burn out. Some routers stay powered on for months or years. It’s probably not a very viable long-term solution to every problem you run into, but it’s definitely a great first way to try.
  • ADSL can be very sensitive to environmental influences. Always keep nothing near the router that could cause electrical or radio interference. In extreme cases, problems have been known to be caused by devices such as cordless kettles, Christmas tree lights, or aquariums. In general, however, you should be careful with devices such as scanners, alarm systems and anything else that the radio or radio sends or receives. This is sometimes easy to spot because there is a direct correlation between when the interruption occurred and when the problem device was turned on or off. So be careful. If possible, make sure your ADSL router isproperly insulated.
  • Test the analog phone on the line and check if there is noise or crackling on the line, and a low dial tone or not. You can also talk to your phone company about running certain tests remotely to rule out any problems.
  • Another thing to look out for in a physical environment is the cables going into the router. Many offices neglect to protect wires from obstacles, and they can bend, twist, or run over a table or chair. Cables are very important and can be damaged very easily. The longer the cable, the more likely problems will arise. Always keep an eye on them and make sure they are protected and not endangered.
  • If you’ve tried everything and everything you could think of could cause any of the above problems, you probably need to talk to your ISP. Always let them know what you’ve tried and what haven’t tried to continue the troubleshooting process. Also, be honest with them – talkTelling them that you did something if you didn’t do it is bad, it will only slow down the process.

I Have A Slow ADSL Connection

Another very common complaint from ADSL or any other form of connection is that the line in the department is below average. Again, you will probably have to talk to your ISP about any issues you have, but it’s always best to try to fix the problem yourself first, or at least do extensive testing to analyze it.

Many of the most common causes of slow connections can also be caused by intermittent connections. See the previous section for more information. Another problem that can arise when using wireless ADSL is that a third party can use your connection without your knowledge. Check out our essential troubleshooting guidethe consummate to learn how to get rid of this possibility.

Also make sure that the bandwidth you provide to your office is adequate for the needs of your user base. It is very easy to underestimate the bandwidth requirements of your network, especially if you are using an inexpensive product like ADSL. A good way to test this is to ask your ISP to monitor the connection or implement some monitoring tools yourself. If you find that your usage patterns are often at their peak, your speed is probably not fast enough for the required bandwidth and you will run into low speed issues. Talk to your ISP about updating the product you are using.

If you have resolved all of the above and it is obvious that the issue is with your speed, you should file a bug with your ISP. You should be able to shed some light on the situation and adjust some of the profiling values ​​on the line to improve the sieve.uation. In some cases, an engineer visit may be required. Always try to run line speed tests at different times of the day before contacting your ISP so that you have as much useful data as possible. A good site for this is www.speedtest.net. If possible, you should always try to run tests with a laptop or PC connected directly to the back of the router.
