upgraded internet today but its slower

[Calling John]

so we got fiber installed  my ping on speedtest and in games is much lower  but compared to when we had vdsl my internet speed for downloading is worse

im using a 150mbps usb 3.0 dongle

 

before with vdsl i got around 50 mega bit down now im getting around 25mgea bit

 

what is causing this

First, when testing speed you should connect directly to the modem/router with ethernet to remove any problems caused by wireless signals or dongles.

 

Second, what speed plan did you purchase from your ISP?

i can't remember off the top of my head but i know it should be much faster then vdsl  also my computer is in my bedroom and i don't have a long enough lan cable

Unfortunately that will prevent you doing any meaningful diagnostics.

No ISP will respond to complaints if you are using WiFi, especially with a 150Mbit stick as its likely using 2.4Ghz only which is not at all uncommon to get speed drops that severe, or worse.

I'm surprised you ever got 50Mbit, I've had days where I could only get 25Mbit on WiFi supporting 2x2 MIMO on 2.4Ghz and 150Mbit sticks are usually 1x1 SISO which is half the speed.

Do you know what router you have?

Can you go into Control Panel, Network & Internet, Network and Sharing Centre, Click on your WiFi connection in there to see the link speed.  At the very least you probably need a better WiFi adapter.

 

If you changed router as part of the upgrade its probably just not got as good range on WiFi so using an older WiFi adapter is holding you back.

Might also be worth noting that many ISPs ask you to wait 2-3 days so that your connection can stabilise. and by the sound of things, that dongle of yours might also be the weak link here. I'd also vouch for you getting a LAN cable if at all possible. I know they're super messy and all. but they're very reliable and will give you a high chance of getting the speed you pay for.

my mum used her phone with our old vdsl internet in here room and would get like 75% signal with this new fiber she get like 10 to 15 % signal


this is our modem https://www.spark.co.nz/business/shop/internet/modem/
this is our old one Huawei HG630B

Is that modem (actually router) broadcasting a single SSID (the name of the WiFi connection) or one for each frequency?

It could be your mums phone is latching on to 5Ghz now when it was 2.4Ghz before.  Sometimes this can work better (even when a weaker signal), sometimes worse, which is why I always use a different SSID for each - so you can manually change if automatic isnt working correctly.

Either way I'd still highly recommend you get a better USB WiFi adapter for your PC and ideally a nice long ethernet cable for testing (or temporarily move your PC into the same room as the router).  Otherwise were not going to know if this is a WiFi problem or not.

It seems from your later replies you're from New Zealand and your ISP is Spark. 

They actually have (or had) a 30/10 Fiber plan, so you should double check with Spark that:

A) You're on a faster plan (e.g 100/20) and;

B) That your plan is provisioned properly. Sometimes there have been mistakes where they applied the incorrect profile. 

 

As others have pointed out though this could be Wifi related. I could barely get 50Mbit on that Huawei HG659b despite apparently being 3*3 MIMO.

If you have a mobile from the last few years, you might want to try testing close to the router with the Speedtest app. Also make sure you're testing to the Spark Speedtest Server. 

You might also want to check your wifi connection and make sure you're connected on 802.11ac (5ghz).
