Full Fibre 500 upgrade speed only averaging 50mbps

mpsoborne — Tue, 11 Mar 2025 08:38:36 GMT

I upgraded to 500 last week and my speeds are consistently way below, around 50mbps download speed, this is now slower than what I upgraded from! What could be the problem?

@mpsoborne what product were yo on previously, with whom, and how are you measuring your speeds - wireless or wired?

Plusnet Unlimited Fibre Extra was my previous package. I'm checking speed using wirelessly, I don't have a spare ethernet cable. Nothing else in the house is currently using broadband.

@mpsoborne

To isolate this problem you really need to get a wired connection to the router to test with.

Currently you have two potential problem areas: the connection between your router and Plusnet, and the WiFi signal within your home.

Ah, so you switched from FTTC to FTTP. Did you run, or did the installation engineer run, a speed test when he had completed the installation, to check it was running correctly.

One quick suggestion, which may or may not help - try resetting the ONT.

@mpsoborne if @jab1 s suggestion dosent give any results

you need to make sure that the device is connecting to the 5ghz band. A 50Mb speed looks remarkably like its connected to the 2.4ghz band in which case 50Mb is about what you'll get!

I don't know if the engineer did a speedtest, he didn't mention it.

How do I reset the ONT, sorry not very technically minded.

I realise using a cable would give a more accurate speed but I am using the same laptop in the same position, the router is in the same position as before so surely it should reach faster speeds than it currently.

To reset the ONT , press a paper clip or similar into the reset hole on the R/H side until the lights flash, release and wait until all three go green.

Looks like it is using 2.4ghz band, how do I change it to 5ghz ? will this affect anything else? Thank you.

@mpsoborne assuming the laptop is running Windows , https://www.thewindowsclub.com/how-to-force-wifi-to-connect-over-5ghz-in-windows-11-10

It wont affect anything else

Have managed to change laptop to 5ghz, checked speed using plusnet speedcheck now getting around 90mbps, still long way off 500

Have you reset the ONT?

Re: Full Fibre 500 upgrade speed only averaging 50mbps

MisterW — Tue, 11 Mar 2025 11:26:15 GMT

@mpsoborne after the ONT reset, check that the link from the router to the ONT is showing 1Gb.

To confirm the Hub and ONT connection is 1Gbps look here :- http://192.168.1.254/basic_-_status.htm WAN link speed.

I did ONT reset, lights didn't flash they all went out except for power light, waited, nothing happened so switched off at socket and restarted, lights on green again, checked router status WAN link speed shows 100mbps.

@mpsoborne

"WAN link speed shows 100mbps."

Replace the ethernet cable between the router and the ONT.

I don't have a spare one, (as it was the engineer had to use the one that connected my central heating hub) I'll have to order one from somewhere.. does it have to be a particular sort? Thanks.

So long as it is Cat5e or better, no.

@mpsoborne if you want one quickly and have a Toolstation

nearby then

https://www.toolstation.com/cat5e-utp-patch-lead/p15584

https://www.toolstation.com/cat5e-utp-patch-lead/p14536

https://www.toolstation.com/cat5e-utp-patch-lead/p31020

will do fine depending on how long a cable you need

@mpsoborne There is another thread on this board where the WAN link speed was 100Mbit and restarting the Hub2 router cured the problem. The poster actually changed the power supply and came to the conclusion that the original one was faulty, this is debateable, it may just be the power reset that caused the Hub to connect at 1Gbit. Could be worth a try.

This is the thread ..... Incorrect WAN link speed

Your central heating hub won't need >100mbps, so if the lengths of the cables are appropriate you could just swap them over (at least until you get a new cable)
