How can consumers determine whether their phone lines will support the advertised speed?

Speeds should only be advertised if at least some consumers are actually able to achieve the advertised speeds.

As everybody knows, there's a notorious gap between advertised "up to" and actual broadband speeds.

In other words, around 45 percent of the advertised speed.

Ofcom's survey determined that download speeds averaged at around 31.8Mbps-80 percent of the advertised speed.

The difference of actual to advertised speeds for DSL compared to the others may have modest.

All the advertised speeds are available as distinct gear ratios controlled by a single shifter (except for some early 5-speed models which used two shifters).

They never have given us the advertised speeds.

The fibre-optic broadband is excellent and delivers close to the advertised speed of up to 10 Mbps, while the phone package offers free weekend calls.

Very low bandwidth (these were the 85mps ones) and nowhere near the advertised speeds even with a house rewiring.
