I live in Auckland and don't have access to Fibre yet. My (Vodafone) VDSL speed is approx 42 Mbps

A relative in Rotorua just upgraded to Fibre. I was expecting to see amazing speeds.....

but over the last 24 hours it's been approx 28 Mbps.

Why is her Fibre 34% slower than my VDSL?

Did they buy a 30/10 Fibre plan? Are they testing on Wi-Fi or a wired connection?

Fibre isn't slower than VDSL, however most plans are speed capped. 30 seems to be the standard speed, but there is 100 and 200 available, sometimes faster. Your VDSL is good, but it varies significantly between connections. I was getting 17 on VDSL in Tauranga.

Thanks for the replies - all tests are WiFi - no cabling at either address.

Wasn't aware of the speed limits - that will be the reason.

Glad my VDSL is fast!

Wifi can give you very mixed results. Test over a cable to avoid this.

Glad to hear you are happy with your vdsl. :P

Dont ever test with wireless, its unreliable to give accurate results especially if your looking for headline rates.

Fibre can go up to 1000/500, and you get previsioned what speed you pay for.

VDSL can go up to 100/50 (or 70/30 Depending on linecard) and you get what your profile will allow combined with loss over distance being a factor - 99% of people will likely never see a capped out VDSL line, Same cant be said for fibre.

VDSL also has copper error correction inplace, most noticeably the interleaving values which can result in FAR FAR higher latency than fibre.

If you want to look at it another way, VDSL is active gear, where as Fibre is passive for the most part. What this means is in a power outage, your not reliant on cabinets running on battery backups. (assuming you have power backups at your end too ofcourse.)

There are so many points to look at, but at the end of the day VDSL is a stepping stone to fibre.

Most isps are opting to have their entry level fibre at the 100/20 profile now days, which will be faster than VDSL in the downstream and very often in the upstream too still.
