5x Hub / Deco x20 Mesh

Not a loose strand but a dodgy socket. Socket replaced, and getting 400 Mbps from an access point down the wire!

It is good to have identified the common denominator that caused the reduced speeds.

Faulty network cables are a very common source of issues, on a Cat 5e or Cat 6 cable we only need to loose one of the 8 strands to either drop from 1000 to 100 or to be totally disconnected.

An update for those who have been kind enough to help.

Looks as thought the cable running from the router to the office (where the switch is) is NOT Cat 6 but rather Cat 5. That would explain why everything coming through that throttles down to below 100 Mbps .

So..... As a medium term solution we have switched to using the 5x Hub as a Wireless router (it covers most of the house - the slowest speed I got was 150MBps) and then installing one of the Mesh units as an AP in my office with close to 100MBps for everything in there.

I find the new forum software lacking, and that's being polite.  Another nod to the "app" generation in look and feel.  Total wasted space and no page navigation at the bottom, just endless scrolling.  I find sometimes when scrolling down, the browser stalls and puts you back at the start ....

Expanded all the "Show more" type of options but still do not see this reply displayed unless I navigate direct to it from the link in my forum profile. URL below ...

It is in the nesting that information has gone missing.

I have found that missing posts can usually be found by changing the oldest/newest selector at the top, and looking for the 'Show More' link between posts. 

But you can't be sure that all posts have been revealed. 

Hello there @Client62,

These forums also perform very strangely for me also.

I made a thread in the Speed subforum, and it is displaying very strangely for me, with many posts missing (not visible or showing in the thread).

I think this has something to do with users regularly using the using the "Reply" button that is nested in the last visible post (a bad idea), as opposed to the "Leave a Reply" box at the bottom (seemingly a much better idea).

There seems to be some kind of glitch when too many "nested reply" posts occur.  The result is that large swathes of posts can become invisible, after they have been made.

This is very frustrating, and prevents useful knowledge transfer and interaction between users and VM colleagues alike.

I am hopeful that some strange aspects of the forum's behaviour can be fixed.

There is an odd issue with this thread, depending on how I come and look at it
changes if I can see my last post or I can not. Other posts are missing too.

At the moment I can not see the posts where the op restated the switch as being a model LS108GP with is a Gigabit device.

Was it a 10/100 switch by chance ? 
That would limit the speed of the mesh nodes.

Is this deliberate throttling by the Hub?

You know the Hub 5x is working ok.

The Wi-Fi hops of the Deco mesh are loosing the speed.
Using a much slower ADSL connection before this would not have been seen,
perhaps the mesh nodes are too far apart.

I would leave the Hub 5x Wi-Fi enabled, think of it as an extra dual band Wi-Fi 6 access point for free.
