Hi All,

Experiencing some technical difficulties with my WiFi, Noticing that it can drop in speed greatly - or just completely fall off.

Done several Hard resets. Done several soft resets. Unplugged the router and replugged the Router, the issue has been going on for at least a month.

I did just a little investigation and noticed this in my network logs. Please tell me If i need to include anything else

You havent said... 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?

Also you are missing 2 tables of data the Down one with RS errors and the Up one with T1-4 errors.

Also, 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

Hi,

Sadly the down one won't become a table and provided the Upstream one as well. Lights seem to be a yellowish constant even when the issues occur

There are no devices in the household connected with ethernet cables other than the router as the house I live in only has the one data port.

You can screenshot the RS table showing the Pre and PostRS error "numbers" per channel

Can you test it with a computer/laptop plugged directly into the Hub on a Cat5e/6 cable - just for testing purposes.

it may well just be a wif issue and there are different pastways to resolution of that or a network connection issue

Your link to a BQM will help in that regard - network issues should be obvious.

You can see 1 spike for today which matches what occurred today - though it probably missed when I spiked before that since I hadn't set it up by then.

Ethernet cable connections? Do this...
_________

Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.

Hi,

No problem at all.

I have done what Jbrenner has suggested - and it has made it slightly more stable. But Noticed today that it dropped again.
