Why is my wifi so slow with new Ultra fast broadband??

November 1, 2019 at 08:09:13
Specs: Windows 10
I have had BT ultra fast broadband installed, the 100mbps minimum one!
On the smart hub 2 manager it is showing downstream sync speed of 137mbps, cabled over 100, however wifi to computers and play stations only 30mbps - what's happening, do I have to change something?? BT engineer could offer no advice at all on this, as it's coming into the house fast enough.
Any advice gratefully received

Wifi is always slower than a cabled internet connection. We need to know what type of wireless equipment you have - wireless G, N, AC, etc. Also, is the wireless signal going out & the wireless adapters on your devices in sync? In other words, are both the same speed? If you're broadcasting wireless AC but using an older device with wireless G, the theoretical max speed would be 54mbps, but distance, walls, & other interference can reduce the speed significantly.

Does it make any difference if you run one of your slow devices near to the router?

Always pop back and let us know the outcome - thanks

On a desktop you can add on an AC Wifi card, disabling the built in Wifi (if any) or removing an older card.
On an older laptop you can purchase an AC Wireless Dongle, disabling the built in WIfi.
On older phones and tablets you may have to settle for slower.

Thank you for replying, but no afraid not, I've got a PC less than 10 ft away, showing 22mbps and a PlayStation 4 showing 30mbps which is just the other side of a door. All BT have offered to do now is send a booster, not sure if that will help, as there does seem to be an issue, there selling point is 100mpbs wifi!!

Good morning, thank you for replying, we are running desk top PC's as work from home and have PlayStation 4's. Plus phones etc, the desktop PC's have been fitted with the latest usb wireless cards capable of 150mbps, (sorry don't know exact type as husband built PC, but he's just bought them and they are the latest available apparently!) Playstations are as they came, not been messed about with, and very close to the modem so would expect them to pick up more than 30mbps.
BT have offered to send a booster, so not sure if that will help at all!

Bring a laptop over to the router, plug it in via Cat5 or greater network plug into the router directly. Run a speed test. If the speed you are receiving hard wired is not at least close to the the max throughput advertised, call them back and they will need to send a tech over to diagnose the issue inside or outside your home. If the hard wired speed is fast then the issue is with the Wifi. Have them send you both a new Wifi router and the booster as long as they are not going to charge you for the booster and return the old one which may be defective. Alternately they could send someone over with a new unit and booster and diagnose the issue onsite. If you are going to reinstall the hardware, make sure that you understand the set up procedure and write down the important settings you are going to need when installing it.

from the BT website: https://www.bt.com/broadband/smart-...

Complete Wi-Fi guarantee

96% UK availability. BT sends additional discs to guarantee at least 10 Mbps in every room of your home. Sky send one additional disc and guarantee 3 Mbps or money back. No other provider offers a faster Wi-Fi Speed Guarantee than BT. To verify e-mail superfast.fibre@bt.com. We’ll send you up-to three discs to ensure a strong signal of at least 10Mbps in every room of your home. If you still can’t get a strong signal we’ll give you a one-off credit of £20 off your next BT bill. Guarantee only applies when your Smart Hub2 is connected to the internet and does not cover broadband faults. For full terms see bt.com/legalstuff.

Not sure what they mean by "additional discs"


In my case, the provider installed a Huawei router with N-WIFI. Subscribed speed at first was 50Mbs then upgraded to 100Mbs. Of course the WIFI did not accommodate the 100Mbs speed, As a free token, the provider installed additional AC-WIFI router/acces point and the speed now nears 100Mbs (depending where you are in the house). So the question is: is your router N or AC standard? Is there a brand/model somewhere on the back of the box?

Good morning

Yes it is most certainly a wifi issue, I've plugged my laptop in with the cable as suggested and the speed test is showing 123.79mbps with 8.35mbps upload. so there is a wifi issue.
I'm still waiting on the booster to be sent from BT have chased again today, so hopefully that will improve the wifi side of things.
At the moment I am just using the BT smart hub 2 that they have sent, they have said it is the very latest in routers, so would not need upgrading or improving, but that's just what they say!
What's quite shocking from above is that BT only guarantee 10mbps in each room with 100mbps service!

Thank you again for all of your advice, i'll plug the booster in once it arrives and see if that changes anything at all.
