Why does my wireless connection keep disconnecting?

Typical wireless connection issues are usually caused by one or more of the following problems:

  1. The wireless adapter/computer is not properly configured to join the wireless network. (This means the adapter is not configured for the proper wireless security type or with the proper security key)
  2. Environmental issues this is caused by
    1. Radio frequency interference caused by wireless devices in the 2.4Ghz range such as cordless phones, satellite systems, microwave ovens, anything producing a wireless signal at 2.4Ghz.
    2. Electromagnetic interference caused by having the modem/router too close to electrical powered devices such as Monitors, stereo speakers, etc.
    3. Structural interference caused by physical things such as concrete/brick walls, heating, and ventilation ducting, metal piping, stucco walls, etc. 
  3. Your wireless device is too far away from the wireless radio transmitter in your Actiontec device. 

Possible solutions.

  1. Change the channel that the modem/router transmits and receives the wireless signal on for interference issues.
  2. If you detect the signal with no issues but can't connect turn off security on the wireless and check the connection. If the device still doesn't connect it is an issue with the wireless device. If it does connect without security then the wireless device is not configured correctly to join the secured network.
  3. Relocate the modem/router to a new location in the house or bldg., for signal strength issues.

If you are still having issues after you have tried the possible solutions above let us know in the comments section below.

  • I have this modem and it is constantly kicking some of the wireless connections offline. We are never using everything that's connected at the same time, but still had issues with it just going offline. I got a wireless extender and moved some items to that, but it will still kick things off. I have tried your suggestions, and still, the same. Is there some sort of limit to the number of wifi connections, even though we don't use them all at the same time? Is there a setting I can change on the modem page? It gets very tiresome to have to keep unplugging and plugging in the modem, only to have to do it again the next day.

  • Elizabeth,

    What Actiontec device do you have? Also, do you know what firmware is currently installed on your device? Can you also tell us when and where you got your device from?

  • Verizon recently replaced the FIOS "entryway" equipment in my home (not the router, but the equipment before the router). Ever since, devices keep dropping from my wireless network and my printer says there are two networks with the same name. I have a Verizon router (compatible with its FiOS quantum service), an Actiontec WCB3000n extender in my basement, an Apple TimeCapsule on my main floor, and an Apple AirPort Express on my top floor. The Apple devices are being used as extenders. Any suggestions on why my network may be dropping devices when moving through rooms since the Verizon work or how to fix it? I called Verizon already but they are no help.

  • Stephan,

    This question would be better asked in our Actiontec community forum. Found here:

    But at first, it would seem that some how the apple devices that you are using as extenders are not configured correctly (or the same as the WCB3000N). We have not seen this kind of setup before so we have not tested it. Unfortunately, we do not have an Apple Time Capsule or an airport express to test at the moment. We will send your issue to our engineers to see if they can come up with a better answer but it might take some time to get an answer.

  • It's strange that anything would be configured incorrectly since it all worked well before Verizon replaced their equipment. I'll play around with things starting with the Apple devices and see if that helps. Thanks!

  • Ok, so it seems that when Verizon replaced its equipment, it caused the FiOS router to reset to the factory default password, which was different from the password being accepted by the network extenders (Apple and Actiontec). So, in rooms where the coverage overlapped between the router and an extender it was as if there were two separate networks with identical names but different passwords. I've had to change the password on the router and then reset each of the extenders. This seems to have fixed things.

  • Glad it got all sorted out for you.

  • I have a MI424WR-GEN3I that I bought on my own with Frontier FIOS service (originally Verizon) and am having DNS issues.

    Randomly the router will drop all DNS services. If I go into the settings and change something it will start working again for a while. It was happening every few days, now it could work for a day, or a few seconds. If I set the DNS manually on the individual device it works fine, it is just the DNS forwarding from the router that is flaky. The only help Frontier would give me is to reboot the router.

    I am running firmware

  • I've tried resetting the router the lights come on but the internet light doesn't appear

  • Jaden,

    It sounds like you restored your router to defaults you will have to reconfigure it for internet access once again to get the internet light to come back on. What model do you have?

  • Lance,

    I would recommend you restore your unit to factory defaults and set it back up and see if the issue is still there. If it is I would recommend replacing the unit.

  • MI424WR Rev. 1

  • I have already restored factory defaults and set everything up again. I was getting ready to replace the unit, I just thought I would give it one more try to see if there was anything I missed. I guess replacement is the only option.


  • Lance,

    Unfortunately, we have not seen this issue before. If you have restored it to defaults with no other custom settings and you are experiencing this issue with all of your devices it is either an issue with the router or with ISP. If its just happening on one device it could be an issue with that one device. So I would recommend replacing the router and then if you are still experiencing the issue it will be something you take back to your ISP and say listen I have had the same issue with two different routers. It is now clearly an issue with my service.

    Sorry, we could not offer any better answers for you.

  • Jaden,

    If you have the cables connected correctly. 1st step would be to contact your ISP and make sure the routers Internet connection is setup correctly.

    Who is your ISP? Is your router connected to and other router or modem?

  • I have a GT784WN using firm ware ver NCS01-1.0.14. My router keeps droping wirless connections or it will not let any new connections. I must unplug and reset the router almost everyday. Please help correct this problem

  • Robert,

    Please give us a call at 1888-436-0657 for that we can help troubleshoot your issue.

  • Robert,
    I had the same problem and had to change the channel on mine. I’m sure the people here can help you or your internet provider. Haven’t had any issues since. Good luck and thanks Admin for all the replies.

  • Hello. I have the WiFi extender and the light for the 2.4 will blink, I unplug it, wait a few seconds, plug it back in and it works for a while, then later it will go back to blink.

  • I am having the same problem of the Actiontec (gt784wn) dropping connection intermittently. All lights are normal, but no connection. For what ever it means, it is setup for PPoE. If I disconnect the power for only a moment, it will operate normal for a while, when it comes back up. This is my second Actiontec. I saw a mention in another comment that over heating may be a problem?

  • Harrison ,

    Please take a look at this FAQ. https://actiontecsupport.zendesk.com/hc/en-us/articles/360002611091

  • May be a little premature, but I place a 12vdc fan on the Actiontec router/model Gt784WN and have not lost connection between the PC and modem. Normally, I would have lost it 2 or more times in a 24 hour period. Checking status, I found the N/F end CRC error counts vary low. Help this helps.

  • Gt784wn. Disconnects all devices once a week. Router requires reboot, unplugging, once a week. I have century link. The router isn't from century link its unbranded.
    How can I I fix this issue? Is it renewing IP address ? Firmware is updated. Thank you.

  • Samantha,

    Please check out this article and get back to us if it doesn't fix your issue.

  • I am having a variant of this same issue with all of my Apple devices (both iOS and macOS). The internet will not stay connected when the device sits idle. When I go to pick up my iPhone, for example, the internet is disconnected. In order to reconnect, all I have to do is go to settings, the turn wifi OFF then back ON again. This has only started recently. The extender worked fine at first (~3 weeks ago).

    I'm using the ECB6200S02 extender.

  • Jim,

    What model of modem/gateway do you have?

  • Cisco DPC3216 cable modem. It's connected to the ECB6200S02 MoCa extender through a coax-to-ethernet conversion kit that I bought from you guys - Model # ECB6200.

    Any advice would be greatly appreciated.

    PS - it's worth noting that when I'm connected to the wifi signal direct from the router (i.e., not through the MoCa extender) I don't have this issue at all. The connection is quite stable. (Model # RAC2V1A 802.11ac Wave 2 Router, if that matters.)

  • Jim,

    The ECB6200 adapters are just Ethernet/coax MoCA bridges and have nothing to do with wireless connectivity. When having your connection issue verify the coax lights are lit on the ECB6200 adapters. If they are green then they are passing network traffic over the coax to your router. If you have further issues contact our technical support at 8884360657 while having the issue so further troubleshooting can be done.

  • I purchased a Actiontec 300Mbps GT784WN modem/router from Amazon back in September and ever since we set it up, we are constantly having to reset the device because all of our devices will lose their connections. Suggestions on how to fix this?
