Multiple devices lagging

[Roland81]

I work from home and my work equipment requires a latency speed of 80ms or lower to work efficiently. I have noticed serious lagging recently and this includes using the works phone line which works via the works system, not my phone line. Having checked my loaded speed it was running at 428ms. I reset my rooter and instantly this lowered my loaded ms number to about 25. However, through the day this jumps up and down from being as low as 25 and as high as 400's. This number changes in line with the speed of my internet. This isn't really impacted my the number of devices being run in the house because I am mainly on my own and everyone else is either at work or school. 

at the time of writing this my internet speed was 57mbps but sometimes goes as low as 15mbps but until recently doesn't seem to have been an issue. Not being very technical I am not sure where to start. Is it, or could it be my internet? Or is it likely to be my work equipment? 

other devices haven't worked on the internet such as I recently purchased the new PlayStation portal which relies on internet. We have sky q multi room that every now and again lags and when when using PS5 online it sometimes lags. All these little things are now making me think it's more likely to be the internet rather than my work equipment.

How is your work equipment connected to your router? WiFi or Ethernet?

Please post your router stats

Hi, I am using it through the Wi-Fi.

Those are not your router stats, please follow the instructions to the end.

Using WiFi is never a good idea for latency sensitive tasks. When your bandwidth is used by the device this can cause WiFi latency to sky rocket as it can't keep up with all the requests. When WFH, especially when you need sub 80ms latency you should be using an ethernet cable.

I was going to get a cable to see if this fixed or improved the problem. I work in a different room to the router so the cable I have isn't long enough. I have WFH for several years and been on the Wi-Fi and not half an issue until recently which is frustrating

@Roland81 

Its quite possible the WiFi conditions have changed whether than be a change to your devices/appliances or neighbouring routers/devices

[Roland81]

Could or should using a cable fix or improve the problem? I recently changed my work equipment so I am not sure if it's a coincidence or if actually the cable should be the better option for reliability wifi

Using a cable should fix the problem
