Assuming Overheating

[HarrySmith]

A while ago i started having problems with the internet randomly going off or going to very slow speeds. I have the 350mbs package and it works fine until i play a game for a while and my computer does produce quite a lot of heat so I assume its heating up the room then the box. I moved it then it was fine. But recently my brother decided to take it apart and to see if he could fix it (He did not ask me aha) and when i looked at it after he did it i touched one of the heatsinks on the board and it was really hot to touch so I couldn't imagine what the actual chip underneath is like.

Would getting a replacement hub fix this because I'm just wondering if there's some sort of thermal compound that has gone or lost its effect overtime.

What VM Hub do you have and is its "overheating" warning light showing?

[HarrySmith]

I have a hub 3.0 and its just the broadband as i dont use this one for sky sports or anything. This hub is dedicated to my computer and mobile devices in this area of the house as i dont get good wifi on our sky box. And it goes a amber colour every so often

[jbrennand]

Yellowing LED is usually just a sign of it fading/failing - only time to be concerned is if it goes to bright red.

Can we check… are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection/Hub related?

What are the various Hub lights showing/doing when this happens if a Hub3 is the base light a steady white/yellowish - or flashing green?

[HarrySmith]

Hey thank you for replying, its doing it right now and it does it on wifi and ethernet devices, the wifi devices just switch networks but my computer which is on ethernet will stay on. However if im in a call for example such as discord it will be fine then the ping will flicker from 30 to thousands and constantly do that, also does it on games so it just constantly jumping up and down and ive done a help diagnose and it says theres no issue which im confused about because there is 100% a issue of some sort

Thanks, Harry

Forgot to add that the light is yellowish and the other 2 or 3 lights arnt showing but sometimes the other lights are either red or amber im pretty sure.

Ok do this
___

Post up your Hub/network connection details and someone will check to see if there is a problem there.  In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) (DONT click these links) - and hit return. On the first page up dont login just click on the “router status” icon/text at bottom-middle (Hub3/4) of the Login page and then Navigate to these “pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs page. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again. If character limits are “exceeded” - just do two posts

If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. Click the lower link (Share Live Graph) then click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK
