Atrocious speeds with fibre

[#1]

Had my fibre installed Tuesday and all was well, I was getting around 30-40 down and 12-18 up. Now this wasn't the speed I was estimated, as I was told I would be getting around 75 down. Fair enough as they had to do that 10 day speed test thingy (not very good at this computer mumbo jumbo stuff).
But here's the bad part, since yesterday i have now been getting speeds at around 2.5 down and 7 up!!, that's worse than my old broadband. Please can someone from Plusnet look into this for me as this is atrocious. Poor customer service this whole month with you and now this.

Hi pbyne,
I'm really sorry to hear that you've got such low Fibre speeds.
I'm just going to take a look at things for you, I'll report back shortly.

Thanks for taking this up Chris

[#4]

No problem at all. Can you just restart your router and check to see if anything has improved please?

[#5]

Thanks again Chris
Resetting the router seems to have worked and getting 35 down 16 up.
Just another quick question though, will i see my estimated speed of 75 after the 10 day period?

[#6]

You should definitely be getting much more than 35 down and 16 up.
Would you be able to connect your laptop/computer directly into the modem as shown here: https://community.plus.net/library/broadband/fibre-help-how-to-set-up-a-pppoe-dialler-in-vistawindow... ?
I'm just wondering if bypassing the router improves things for you. If it regardless of the results, it'll give us something to work on.

[#7]

Sorry Chris but I'm unable to do that due to the computer being up stairs.

[#8]

Does that mean you're connected wireless to the router ?
There are many factors that could make a wireless connection slower than a wired one.

[#9]

Yes I'm connected wireless and I expect in to be slower than if it was connected directly to the router, but I don't expect it to be slower than half of what my estimated speed is. Which is 75 down 20 up

[#10]

Run the BT speedtest - further diagnostics and that will allow us to see the actual download sync speed

[#11]

Ok thanks, before i do that though, i have a 30 meter ethernet  cable, would that work also if i plugged that into the modem to do what Chris said above?

[#12]

Yes, that would work fine. First just try connecting the computer to the router with the cable and do a speedtest. Then connect the computer directly to the modem as Chris says and do another speed test.
Post the results back and we'll be able to advise.

[#13]

Ok to be honest guys, i think its just the wireless connection. Here's my result using the ethernet cable.

[#14]

Yep, it's the wireless. You could try changing channels ( see here for explanation http://www.broadbandspeedchecker.co.uk/guides/improve_wireless_internet_speed.aspx ) to see if that improves things.
Is the card/dongle in your PC Wireless N or G ?

[#15]

I dont actually know its a pc from medion with built in wireless.
