Full fibre 300 but speed VERY SLOW

[#1]

Hi I recently swap from normal cable broadband for full fibre 300 but I had never get this speed since I'm connected.  This weekend upload is just a nightmare lower than 60 MPs..please help

I have exactly the same problem, I had mine installed last Wednesday 23rd and the speed is totally erratic, most of the time in the 60s very occasionally well over 200, but in the main very slow, sometimes well below 60.

I have been in touch with Customer Service and although they have been empathetic to my problem nothing has been sorted at all.

Worst of all they promise to phone me 12 to 24 hours later to check how it is going after their intervention and they never phone back. Having said that I have just had a callback now from Customer Service and he is going to book an engineer visit for me, so some progress now.

If this carries on in this manner I think I will be within my rigts to cancel my contract and go with another supplier.

How are you both connecting to the router (wired or wireless) and how are you measuring speeds?

I can't see any devices wired to either of your hubs at the time of writing, and the most reliable way to test that the service is provisioned at the correct speed is to run a speedtest from a device that is wired to your hub.

Wi-Fi is variable and affected by all sorts of external factors like your proximity to the hub, any barriers that sit between the hub and the device you're testing from, the capability of the device you're running the tests from, which Wi-Fi band you are connected to (2.4GHz or 5GHz) etc.

e.g. if you're some distance from the hub and using a device that is connected using 2.4GHz then 30-60mbps isn't out of the question.

I am testing 1 meter away from the hub.

Sometimes (but very rarely) it reads between 200 and 300, most of the time it reads in the early 60s.

I test it with the Ookla Speed test app and also with the BTW site and they usually concur within 1 or 2 MBs.

If your mobile phone has a Type-C USB connector, you could use an adaptor like this, to run an ethernet cable between your router and your mobile handset.  You will get much more representative results on a speedtest by using a gigabit cable instead of wirelessly.

I am testing one metre from the router, I have also tested with my laptop plugged into the router with my yellow router cable, this is slightly slower in fact.

The fact is that sometimes I get nearly 300 MBS but most of the time just over 60.

Results shown below,

Have you checked -

• That your phone is using the 5GHz WiFi band, and NOT 2.4GHz ?
• That your router WiFi "channel width" is set to 80MHz ?
• Have you done a wireless scan to ensure that your router isn't sharing the same WiFi channel as your neighbours ?

When the laptop was plugged in, was the WiFi switched off ?

Is the ethernet port on the laptop a typical 100Mb socket,  or a recent 1Gb (gigabit) port ?

Were you using an ethernet cable that is rated above 100Mb - a quality cable should have the speed stamped on the sheath.

Using your WIRED laptop, can you post a screenshot of the speeds and latency you get from this speedtest ?

I just gone through random speed tests, two examples from 27th

These tests are three hour apart, between these test what network activity is occurring? 

On a Hub two it is possible to check the wireless connection speed

http://192.168.1.254 Advanced Setting > Technical Log >Event Log , select category WiFi

Two examples

2.4G Client associate from <mac address> (IP=192.168.10.151) RSSI=-51, Rate=72Mbps, host

With this connection you would never achieve anything faster that 72 Mbps

5G Client associate from <mac address> (IP=192.168.10.101) RSSI=-65, Rate=702Mbps, host

With the connection you would archive the maximum wireless speed the Hub supports.

RSSI is the signal strength, the low the number the stronger the signal.

@Dan_the_Van  how are you running those Ookla speed tests?

Are you letting each run of the test 'discover' the server with lowest latency (so far-end server can change with every test), or have you fixed your server of choice in the settings so that you get consistent results ?

I have pretty much given up using Ookla, because I find that in 'finding optimal server' mode, that the lowest latency servers it finds, often have insufficient bandwidth to perform an accurate and repeatable test.  Instead I used to manually have to search for nearby servers (London) that have enough bandwidth, and then do repeated tests on each of say half-a-dozen different targets, before I got a representative result.

On my 80/20 FTTC line, my speed tests of choice are Waveform , SamKnows Whitebox , Thinkbroadband , DSLReports 

and the ones I avoid are BT Wholesale Performance Checker and Ookla

Note the loaded latency/ping results in the second image with the slower speed (aqua and purple icons). Comparing to the first image, it's suggestive that the local network might have been under fairly heavy load when that speed test was conducted? The upload latency is over a second!

[#14]

Difficult to believe there was only 3.3ms of jitter with those high latencies !

Those are @Greytopp tests not mine, see the post with the attached.csv file
