Common Wireless Connection Issues

Many of the users report that their SBG6580 has constant issues with restarting, resetting, intermittent signals, or disconnecting. Below are some of the methods that may fix your connection problems.

You will generally run into losing connection issues when you have lots of interference in the area, or when you are running multiple media wireless streams through your network. In addition, if you found your router constantly restarting itself, the connection issue may come from your cable internet provider as well.

You can usually fix the dropped internet connection by restarting your router. However, if you are experiencing constant wifi outages.

1. Pick a Good Wireless Channel Instead of Auto
Instead of using “Auto” for the control channel, consider fixing the channel to either 1, 6 or 11. Pick the channel that has the lowest interference. Sometimes the router can run into wifi connection issues during the automatic channel switch.

2. Use 2.4 Ghz and 20 Mhz
Some of your older laptops or devices may have higher chance of dropping signals. Consider switching it to the lower band to see if it helps with the signal dropping. In addition, if you use 2.4 Ghz and 40 Mhz, you will find that your wireless connection keep losing.

It should be noted that your older devices may not support 5 Ghz and you will not be able to wirelessly connect those devices.

3. Hard Wire media streamers into your router
A part of the problem that can cause your wireless connection to drop, is when one of your devices flood the network with data. This means that if possible, you should consider hardwire (using ethernet cable) the devices that tend to consume alot of bandwidth. Although this can sort of defeat the purpose of having wireless network, but it can actually help your overall network speed if you can hardwire the bandwidth hogs.

The potential choices include your common media streamers like Roku, Google Chromecast, Apple TV, or computers that download / upload heavily with services like bittorrent.

4. Change SBG6580 Router Placement
If you have your modem hidden inside a small cabinet or next to other active electronics. Your own interference may be the cause of dropped signals. Consider moving your routers to other places around your home to see if the connection improve.

5. Turn off IP Flood Detection and Block Fragmented IP Packets
Many users report having dropped wireless connectivity when you enable IP Flood Detection and Block Fragmented IP packets.

You can turn these two options off under Firewall > Basic. Please see How to Disable IP Flood Detection.

6. Upgrade SBG6580 Firmware
Some users report that updating firmware has fixed their connection issues, however some have reported no changes. You should only pursue firmware update as the last resort.

7. Last Resort – Change Your Wireless Network Setup
If your SBG6580 modem router still drops wireless connection more often that you would like, and you have tried everything to get it to stay connected. It could simply mean that your SBG6580 either generate too weak of a signal or memory cannot handle the amount of work you put through it.

Consider buying another router and place your SBG6580 into bridge mode. And use a separate router to server your home wireless network instead.

  1. My SBG6580 works OK with any wireless or plugged in computers in my home, however I am having issues with a light flashing on and off on the unit that indicates there is someone using it, even though all computers in the home are shut down.
    When I called tech support and asked about this, they told me that this is Wi-Fi working and is normal, however I can’t get over the feeling someone hacked in even though after I changed the password it is still happening.
    When I changed the password a few times the activity light was quiet for a day or two, but then it started up again, that’s why I think someone is hacking in. Is it possible, or can I do something else to make sure?
    I also tried to make the password stronger by using symbols like % ? () but they were not accepted by the system, what can I use that the system will accept, and will make the password much stronger? Please let me know.

  2. Don’t forget to check for problems with your cable setup. Mediacom, my cable provide, has fairly tight signal tolerances of -7mDb to +7mDb. Two of my channels were at -6.8 mDb. So, normal signal fluctuations would knock my cable modem offline. Mediacom replaced my home run, rewired from the pole to the house and finally reduced the number if splits in my house. As a result my signal strength has improved to -4.5 mDb to +4.5 mDb. This is well within tolerance and allows room for normal signal fluctuations. Our modem has been rock solid ever since.


  4. i have a sbg6580. trying to figure out the wireless connection password to enter into my iPhone. how do i find or create a wireless password?

      • You will find a security key behind of your router,you can also find this password by going to login using admin as username and motorola as your password go to wireless bar on the top third from left and go to primary network and scroll down little till you see a box saying show password,now you can just click it and see your password but in your case just see the back of the router

        • You can also go to and use root as user and motorola as password then follow the other instructions from Techhelp.

  5. The wireless on my sbg6580 stopped working. The internet light on the modem does not light, but, I am still able to connect to the internet by ethernet cable. When I go to the residential gateway and log in, the wireless tab on the top of the page is now gone.So, I cannot even urn the wireless on if I try. Has TWC done something to disable this? How can they change the page and delete a tab for the wireless? I talked to TWC customer support and they claim they did nothing. Something changed the interface while I was using it. My wireless dropped twice, I reset it twice, then on the third time, the wireless tab disappeared so I couldn’t reset the wireless.

  6. Is there a simple way to open ports on this router? For some reason it will only allow me 7 devices on the network at a time. In order to have any more devices connect one device has to come off. I’ve searched all over and tried different things but ca’t figure it out

  7. Just got 6580. My computer shows connected to wireless but browsers say webpage is not available. Checked all setup tips above. Please help!

  8. I just got a new 6580 to replace my old 6580. The old one was configured by a tech from Atlantic BroadBand but I never looked at them or thought to copy them down. I can’t figure out the settings and I’m not getting the speed I used to get. Anyone have “best settings” for SBG6580?

  9. Hi

    1) Why “Bandwith” drop-down menu has only “20Mhz” despite my selection of @Ghz/5Ghz above?

    2) May be you know (asked everywhere):
    my Comcast cable internet has a speed of 50Mgbs (and up) – when I connect my laptop (trued several different ones, even brought new one from work) with Ethernet cable to SBG8580.
    But Wi-Fi – even in the same room, 10ft distance, is always 20Gbps (same speedtest.net)

    Are there any configuration settings on SBG8580 that limit the speed?


  10. ” 20Gbps” – meant “20Mbps” – much-much slower than connected speed 🙁

    By the way, it’s only download speed issue, while upload is the same 10Mbps being it wi-fi or ethernet cable

  11. So, I’m trying to setup the guest wifi, however, there is not Guest Network button on my router interface. Do I need to enable it somewhere else or doa firmware upgrade? Please Help. I have a Motorola SurfBoard SBG6580

  12. I have a private CMTS and cannot locate the code to push the SSID, Password, and bandwidth caps through the MIB file to manage the WIFI section of these router/modems. We have found the code to manage the ethernet ports.

    If anyone has this information it will be appreciated.

  13. I was getting .4 mg upload.(ARGGG) on Wifi(50 mbs ethernet) after my ISP updated my account. I had the channel set to auto and the router said there was no interference on channel 11. However,when I manually set it to channel 3 I got the proper speed(relative to my ISP plan) of 37mbs upload and 5 dowload. Most of the setting you suggested were defaults on my SBG6580. I had to switch it out and remove the ISP’s Arris because I kept getting the deadly “timeout dynamic packet exchange failed” I tried everything on Technet to resolve the issue but nothing worked. The SBG6580 resolved the problem. Works like a charm(so far)

  14. I have an Ooma Telo voip phone attached to this modem/router. Is there any Qos settings that I can or should set on this modem/router to help make my Ooma Telo work at it’s best? thanks
