Slower than a Gigabit snail race in Area 01

Ok things checked/actioned: Rebooted modem (latest V4), checked coax, checked Cat6 cables, WiFi is off on the modem.

Running speed tests directly at the modem with my laptop (less than 18 months old running the latest version of Win 10 and using the admin account) with a WIRED connection, today I am getting ~60-90Mb down out of 1000Mb.

Have had the Gig service for about 12 months now and I never get more than ~500Mb.

Have phoned on multiple occasions to be told there is nothing wrong with the modem or last mile.

Anyone any suggestions other than phoning in.

Am gonna be phoning in to claim about 12 months worth of my service costs back.

At a loss & frustrated

P.S. I am technically adept having managed the infrastructure for a major global company for many years

Re: Slower than a Gigabit snail race in Area 01

Boot it into safe+networking mode and put the Hub in modem mode. That will give you the maximum speed possible.

As you are tech savvy I wont mention ethernet cable failures and bad NIC cards defaulting to 10/100 or Dell's killer wifi cards, etc 🙂

Re: Slower than a Gigabit snail race in Area 01

Yeah have checked everything you suggest, hub is always in modem mode and I have numerous cables that test fine and I don't use the wifi in modem, wired is the way forward.

service is still at the mentioned levels

Re: Slower than a Gigabit snail race in Area 01

Upstream power is out of spec.

However it is the right modulation somehow.
