Britain slipped down the global broadband speed table, going from 34th place in 2019 to 47th this year - a result of a slow pure fibre network rollout, experts say.
The Worldwide Broadband Speed League gathers data from more than 570 million speed tests in 221 countries or territories around the world to create a comparison.
The 2020 table revealed that while the UK average speed had increased, from about 22 Megabits per second (Mbps) in 2019 to 37.82Mbps, its table place had dropped.
The UK has fallen 13 places because it hasn't been able to increase its broadband speeds as fast as other places due to a slower fibre optic network rollout.
The top three spots in the table were all taken by small nations including Liechtenstein, Jersey and Andorra - all with more than 200Mpbs average speeds.
The US is placed 20th with an average speed of 71.30Mbps and Australia is in 62nd place with an average speed of 25.65Mbps.

Pure fibre, also known as Fibre to the Premises, involves delivering broadband over fibre optic cables straight to the home or office.
In other types of fibre broadband delivery, the fibre goes to a location junction box and is then the internet is delivered to the home from there through copper cables.
Europe was the fastest region with a continent wide average speed of 81.9Mbps - that was more than three times the global average of 24.84Mbps.
According to Cable.co.uk, the company behind the research, the UK is 'dwindling' in 47th place due to the fact Openreach has been slow in rolling out pure fibre.
The UK still finds itself a long way behind many nations of equal or greater size.
'Ultimately, the UK, specifically Openreach, is comparatively late in its rollout of pure fibre networks, which is causing the UK to stagnate, while other nations gain ground,' according to Dan Howdle from Cable.co.uk.
Around 60 per cent of the UK has access to the Virgin Media network and can get speeds of up to 516Mbps, and there is limited availability of smaller networks such as Hyperoptic offering gigabit speeds, according to Cable.co.uk.
However, they said the Openreach network remains the anchor that keeps average speeds in the UK comparatively low.
Entry-level fibre packages and 'fast' fibre packages on Openreach have been set at around 30-35Mbps and 60-70Mbps respectively for more than five years now with no significant changes beyond how those speeds are advertised.
Catherine Colloms, MD for Corporate Affairs at Openreach said the UK has been prioritising delivering decent broadband to the vast majority of homes over superfast full fibre to a monitory of towns and cities.
'Today though, we're investing £12bn in the next big build and taking ultrafast, ultra-reliable full fibre broadband to 20m premises by the mid-to-late 2020s.'
Colloms said data like this league table should be considered in more detail and look at the difference between current and available speeds.
'Experts at Thinkbroadband have calculated that if everyone bought the fastest product available to them, the UK's national average broadband speed would be a whopping 385Mbps.
'That said, we'd always recommend considering a range of measures like pricing and quality of service – and not just speeds – when comparing the UK to other countries.'
Small territories have been able to more easily roll out full fibre to every home or office and Jersey was one of the first places in the world to make the switch.
Daragh McDermott, Managing Director of JT, the Jersey government owned telecom provider, said since completing their full fibre rollout - to replace all copper connections - they have quadrupled minimum speeds from 250Mbps to 1Gbps.
'This ensures the best possible experience as more and more of us are working and schooling from our homes,' McDermott told MailOnline.
'We are extremely proud that our network is able to deliver some of the fastest speeds in the world and that we have been able to support our island communities during these challenging times.'
Howdle, a consumer telecoms analyst, said there was an increase divide between the 'have and have nots' of global broadband.sonos sonos One (Gen 2) - Voice Controlled Smart Speaker with Amazon Alexa Built-in - Black read more
'While global broadband speeds continue to trend upward, the truth is faster countries are the ones lifting the average, pulling away at speed and leaving the slowest to stagnate,' he explained.
'Last year, we measured the slowest five countries at 125 times
