Net slow or unresponsive

Tuning in

Since today, my net has become unstable and slow. It's a form of income for me and I need it to be stable. My download seems to be fine, but my upload speed just tanks often. The network tester claimed no faults and turning the router off (waiting a minute) then turning it back on again did nothing.

A few weeks ago, something similar kept happening after there was an outage in my area. I was on the phone with a Technician who did something to my local network that made it work again, until today.

Please help.

You seem to be missing some upstream channels....can you reboot the hub leave it off for 2mins

Your hub might be faulty 

---------------------------------------------------------------

Will do. Other folks have been getting problems around here too.

Its meant I've lost out on a £40 job today, which I'm mad about.

That BQM looks suspicious its fine and then goes pear-shaped at 10.00. Is that pattern repeating every day - what does a full working day look like? Say last thu/fri?

I am thinking it might be the dreaded..... "Overutilisation" issue. Only VM could confirm that or say otherwise. If it is..... there is only one guaranteed solution for you.

I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired, 2 on WiFi) Hub5 in modem mode with Apple Airport Extreme Router +2 Airport Express's & TP-Link Archer C64 WAP. On Volt 350Mbps, Talk Anytime Phone, x2 Mobile SIM only iPhones.

It's hard to say. I don't see a pattern really.

I had a week of OK net. Then it goes wild. 

This has been the third instance of this happening in the span of a couple months, and it will do it for a couple days.

First instance: Phoned VM. Tech did something and my net was fine.

Second instance: I let it ride and it sorted itself out.

And this is the third.

Have you got any other devices/equipment routinely plugged into the Hub on an ethernet cable?

Try 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 see if you now have 4 upstream channels.

If not it will need a tech visit to sort - report back here

When you say Upstream channels. I assume you mean these? I've also got 2 desktops connected to the router and 1 spare.
