Massive difference between Ethernet and Wifi

newtothiscompany — Wed, 17 Feb 2021 20:45:15 GMT

Hey All

We have FTTP at 900mbps which has been in for a week.

On an old PC connected by ethernet we are getting 1.2Gbps where as a new laptop with WiFi6 we are getting 15Mbps in the evening its right next to the HH2 (During the day we can get 200-300 on the Laptop) - there is no other significant loading on the network either. Called BT and they did say our speed to the modem was slightly lower than expected. A BT engineer is coming tomorrow but is there any possible issues that I should check on the HH2.

Any ideas.

Just to add have been checking with FAST.com as BT suggested and also have to BT Wifi Discs all with excellent connection.

Have you turned off Smart Setup?

What is Smart Setup on the BT Hub? How can I turn it on and off? | BT Help

Yeah I had to as our sonos wouldn’t work with Smart Setup

We also had two HH2 sent so different serial numbers that wouldn’t be the issue would it if they expect another HH2

If I have read your post correctly you are saying you get 200 - 300 Mbps via wireless on your laptop during the day but only 15Mbps via wireless on your laptop in the evening. If that is correct it would appear that there is some sort of inference affecting your wireless connection in the evening.

Is there any electrical device that is switched on in the evening that coincides with the drop in speed?

I wouldn't expect the serial number to make any difference.

Just for clarity, how many routers are connected to your network? multiple routers can cause a problem if not correctly set-up.

Hey thanks for message. I have checked and there’s nothing that I can see affecting this in the evening. I tried this tonight and no others were in and the only thing on was the TV which was on during the day.

So I have just plugged in a Netgear Nighthawk router to the HH2 and get 210Mbps when connecting to BT HH2 immediately after I get 11Mbps

Why are you connecting the Netgear to the HH2? If you want to use the Netgear, connect it to the ONT instead of the HH2

When you replaced the BT Hub with the "new" BT Hub did you also change the power plug?

It was just to test the speed difference its not to be used. We wish to use the HH2 as we have digital phone which needs HH2.

So you have SH2 connected to broadband and Netgear Nighthawk connected to a LAN socket on the SH2?

If that's right then you need to disable the DHCP server on one of the routers, it doesn't matter which one as long as they're both on the 192.168.1.xxx subnet

Openreach did the install I did notice the plug they used had the other SSID on it

It could be the "old" hub's power plug is causing interference. Fit the new one and see how you get on.

Sorry I dont think I was clear.

The netgear was simply plugged in 10 mins ago to test the speed via wifi and was getting 200+ when unplugged and switched off the speed from BT HH2 went back to 15Mbps.

BT have the other HH2 and from the looks of it the incorrect Power Supply.

I suppose will have to wait to see what they say tomorrow. I have many screen shots of different devices at different times of the day showing the speed decreasing to the evening of about 15Mbps

If it was the power supply I would expect it to be faulty all the time but it is worth checking it if only to eliminate it from the problem.

Is there any pattern to the speed drop?

Re: Massive difference between Ethernet and Wifi

newtothiscompany — Wed, 17 Feb 2021 22:09:58 GMT

No real pattern it just appears to suffer on an evening however as said the Netgear is giving 200+ and as it’s simply plugged into the HH2 I would expect the HH2 to be capable of speeds higher than 15Mbps.

Maybe I should check if someone in nearby house has an old TV like that couple in a village that caused all the service to stop lol

Re: Massive difference between Ethernet and Wifi

It is capable of more. Check the wireless mode in Advanced settings, it should be set to Mode 1

Re: Massive difference between Ethernet and Wifi

newtothiscompany — Wed, 17 Feb 2021 22:19:55 GMT

yeah it’s on Mode 1 calling BT earlier they did ask to switch to Mode 2 but found no different and so switched back to mode 1 and reset
