Slow WiFi, fast ethernet, please help!

Hello, I'd be extremely grateful for any help -
Our WiFi is VERY temperamental and inconsistent. I can run two speed tests within a minute of each other, one will return around 40mbps and a moment later 0.2mbps download. Upload is always a consistent 15mbps. Ethernet we receive a consistent 50mbps so I am confident the issue is with the WiFi.
I've raised this with plusnet but feel we are close to exhausting all options. We've had an engineer out who can't find any issues, he also replaced our master socket. We've tried a new router, changing the channel, disconnecting all devices. Also tried switching off anything that may be causing interference, microwave, baby monitor etc and this makes no difference.
WiFi extenders have been suggested but we only have a small house and are always within 10 meters of the router so not sure this will help.
The engineer suggested it may be the materials the house is made of weakening the signal, but wouldn't the speeds always be slow rather than up and down?
It's so frustrating, the majority of the time the internet is unusable. Please help before I throw the router out the window!!!

Re: Slow WiFi, fast ethernet, please help!

Welcome to the forums @TLBarrett Hopefully other, more technically savvy, members will respond as well as me, but to be honest, Wi-Fi performance has so many variables, that it close to impossible to track down the cause. Just a couple of questions to start - Which routers have you tried, are they plugged into the phone master socket (which type), and how old is your home?

Re: Slow WiFi, fast ethernet, please help!

Thanks John. I've only used the Plusnet Hub One routers, I've only recently discovered I can use other routers so will look into this! Not sure what you mean by which type of master socket - sorry - but I don't think the issue is there, as the engineer replaced it when he visited a couple of weeks ago. The house was built in the 60s.

Re: Slow WiFi, fast ethernet, please help!

D/load a free wifi analyser programme, then check which channels are least used in your vicinity.
Use those not showing neighbour use; additionally ensure the SSID's for the 2 frequencies 2.4 /5 ghz are given different names on your router.
Ensure router not near a source of wifi interference, such as Nest/Hive heating controllers etc etc.
That may help.

Re: Slow WiFi, fast ethernet, please help!

OK. Hadn't seen your GEA test until this morning, and that, as far as I can interpret it, says there is nothing wrong with the connection - as I expected when you say your ethernet connection returns a constant high speed, so the problem IS the Wi-Fi aspect.

The question re master socket was probably badly phrased, but I am assuming from your comment about the engineer that you have a Master Socket 5C with a Mk4 faceplate - largely irrelevant, given those test results, but it is a standard question.

If the house was built in the 60's, do you know what type of insulation you have - it's not foil-backed by any chance?

You say 'always within 10m of the router' - that is a reasonably long distance, especially if any of your equipment works on the 5Ghz band. I have an older, more efficient ADSL router, but even that loses connection with my iPad at about 12m.

By all means, try a different router - for a cheap(ish) option, the BT HH6 is available (in reducing numbers) on eBay.

Re: Slow WiFi, fast ethernet, please help!

Hi there are two things to keep in mind, 1- WIFI connection (dual-band 2.4GHz & 5GHz) if your device supports 5GHz you should receive your full speed and if not than half. 2-distance from your hub it affects a lot on 5GHz not so much on 2.4GHz

@ecrTech Don't understand your first comment, point 2 is valid, but not applicable in this case I don't think, unless the OP has devices which use the 5GHz band, which usually means very modern equipment, but we don't know if they have it.

Re: Slow WiFi, fast ethernet, please help!

most devises support only 2.4GHz so they will give you half of 5GHz speed.

Absolute nonsense. 

 

In theory the poster should see full speeds with wifi whatever the band, your comment is factually incorrect and confusing.
