Hub5 - Disconnections and 5Ghz dropping

Good afternoon,

I've had some issues with my broadband over the last few weeks.

  1. I run separated 2.4ghz and 5ghz bands and have done for years. Lately the 5ghz band keeps disappearing completely.
  2. My main PC uses an ethernet connection to the hub, but I've been experiencing frequent disconnections. I often work from home and have been dropped out of a number of meeting recently, which just isn't acceptable.

Some examples below (I've been disconnected on everyone of those latency spikes):

    Lets see the full data set - can you do this...

    ___________________________________

    Navigate to these “data 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 pages. 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

      Hi John

      Are these what you mean?

      I've just factory reset, so you can likely ignore the end of the log!

        DS channel power levels are high and there is a handful of 3.1 downstream uncorrectable errors.

    BQM not going to show problems with Ethernet unless in modem mode

    Have you reinstalled your PC?

  • Try a factory (pinhole) reset of the hub (you will have to reset the bands again afterwards). 

  • Last time I had a fault that required an engineer one of the forum mods was nice enough to arrange everything (rather than re-explaining everything over the phone to somebody new). Is this still something that happens here?
