Red light on hub 3 - unstable connection

[craigchaos88]

Hi, recently my hub has been unstable, constantly requiring me to do a reset, I use it in Modem mode and still I keep loosing connection needing to reboot. I have noticed that the status light has turned to a solid red since these issues have been present.

Any help would be appreciated.

Thanks

Are you sure it’s red? Hub3 in modem mode the LED is magenta and can look red to a lot of people. Please post some stats. 

How to get stats from a VM hub (no need to logon to the hub)

Open a web browser and go to 192.168.0.1 router mode or 192.168.100.1 modem mode

• Click on the “> Check router status” button
• Click on the “Downstream” tab, copy the text and paste into your reply, do not take a screen shot
• Click on the “Upstream” tab, copy the text and paste into your reply
• Click on the “Networking” tab, copy the text and paste into your reply.
• Do NOT post photos or screen shots they will be rejected as they contain MAC addresses. The board software will automatically change MAC addresses to **:** if done as above.

Hello craigchaos88

Sorry to hear of the red light and connection issues in regards to your Hub, we appreciate you taking the time to raise this via the forums.

When using the Hub in modem mode it should show the base light as a magenta colour, due to it currently being in modem mode we're limited as to what we can see in regards to the Hub and it's stats but what we can see, all of the levels and specs are in the ranges we'd expect them to be.

Please can you try this for me:

• Turn the power switch off on the back of the Hub.

• Ensure the Hub is upright, in a well-ventilated location and out of direct sunlight, if possible.

• Switch the hub back on at the power. The Hub should now operate normally.

Please report back with the result.

Rob

Hi craigchaos88, 

Thanks for providing that information. So we can continue to support you, can you let us know how things were after you followed the instructions in Rob's post above? 

Once we know the results, we can then look to help further 😊

Thanks, 

[craigchaos88]

Hi, sorry for the late reply. The issue is still present and getting worse. I have my router in modem mode and have reset the WiFi router which I have connected also. I have read on other posts on this forum that the red light indicates that there is an internal fault with the hub. It is free from obstruction and is well ventilated. I am worried this may cause a fire as the other posts have suggested its an overheating issue.

… and before the Forum Team ask you to put your Hub into router mode (which will be a complete waste of everybody’s time), the Red light is a matter entirely local to the Hub itself and its guts.  

Is the Hub warmer/hotter than you would think to be normal?  If so, I recommend you don’t leave it on unattended.
