Re: Really low speeds - please help

Often this can be due to an ethernet cable failure. Can you try it on a good new Cat5e or better one first.

At the came time 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 (they my have "loosened"). Also 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.

Then do a Hub “pinhole reset” - but, make sure the 2 passwords on the Hub sticker are still there and legible first ! Disconnect any ethernet cables from the Hub, and then with the Hub still "switched on" throughout, press pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it there firmly for 60 seconds – release the pin then leave the Hub 10’ to stabilise.

See if that helps.

I note also that you are using an old Superhub2 and so are eligible for a free Hub3 upgrade. If you want it, you could try the "free" SH1/2/2ac upgrade/replacement scheme - see the link below - as they are trying to get everyone onto Hub3's.

It works first time for about 50% of customers, but if you get the - "Ooops - please call" message, then come back here for more assistance before calling.

Re: Really low speeds - please help

Thanks for that. The poor speed over wireless connection seems to mirror the wired connection (i.e. when it's bad, so is wifi, when it's worse, so is wifi) so I was ruling out any cable issues.

I have just placed an order for an upgraded hub - thanks so much for that as I had no idea that was an option - here's hoping it works!
